概述
通过对数据库中一张表的CRUD,将相应的操作结果渲染到页面上。
如果想查看Spring Boot架构的同等规模的项目,可参考此篇博客Spring Boot项目实例——简易版商城管理系统
由于广大读者要求源码,作者通过这篇博客还原了项目(当然有一些隐藏的坑),然后将该项目上传到了Gitee,在末尾的后记部分有源码地址,读者可参考。
准备
-
环境:
- IDEA
- MySQL 5.7.19
- Tomcat 9
- Maven 3.6
-
要求:
- 掌握MySQL数据库
- 掌握Spring,
- 掌握SpringMVC
- 掌握MyBatis知识
- 掌握简单的前端知识
实现
1.搭建数据库
- 创建一个存放书籍数据的数据库(ssmbuild),并在该数据库中建立一个名为books的表,代码如下:
CREATE DATABASE `ssmbuild`;USE `ssmbuild`;DROP TABLE IF EXISTS `books`;CREATE TABLE `books` (`bookID` INT(10) NOT NULL AUTO_INCREMENT COMMENT '书id',`bookName` VARCHAR(100) NOT NULL COMMENT '书名',`bookCounts` INT(11) NOT NULL COMMENT '数量',`detail` VARCHAR(200) NOT NULL COMMENT '描述',KEY `bookID` (`bookID`)
) ENGINE=INNODB DEFAULT CHARSET=utf8INSERT INTO `books`(`bookID`,`bookName`,`bookCounts`,`detail`)VALUES
(1,'Java',1,'从入门到放弃'),
(2,'MySQL',10,'从删库到跑路'),
(3,'Linux',5,'从进门到进牢');
- 写好数据库的配置文件database.properties,该文件可以放在resources目录下,代码如下:
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/ssmbuild?useSSL=true&useUnicode=true&characterEncoding=utf8
jdbc.username=root
jdbc.password=123456
- 在Maven中导入数据库连接所需要的驱动包(mysql-connector),代码如下:
<dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>5.1.47</version></dependency>
2.实现pojo层
在项目的java目录下新建pojo包,因为数据库中只有一个表,所以只需要编写一个实体类Book即可,代码如下所示:
package pojo;public class Book {private int bookID;private String bookName;private int bookCounts;private String detail;public Book() {}public Book(int bookID, String bookName, int bookCounts, String detail) {this.bookID = bookID;this.bookName = bookName;this.bookCounts = bookCounts;this.detail = detail;}public int getBookID() {return bookID;}public void setBookID(int bookID) {this.bookID = bookID;}public String getBookName() {return bookName;}public void setBookName(String bookName) {this.bookName = bookName;}public int getBookCounts() {return bookCounts;}public void setBookCounts(int bookCounts) {this.bookCounts = bookCounts;}public String getDetail() {return detail;}public void setDetail(String detail) {this.detail = detail;}@Overridepublic String toString() {return "Book{" +"bookID=" + bookID +", bookName='" + bookName + '\'' +", bookCounts=" + bookCounts +", detail='" + detail + '\'' +'}';}
}
3.实现dao层
- 在项目的java目录下新建dao包,编写dao层接口BookDao即可,代码如下所示:
package dao;import org.apache.ibatis.annotations.Param;
import pojo.Book;import java.util.List;public interface BookDao {//增加一个Booksint addBook(Book books);//根据id删除Booksint deleteBookByID(@Param("bookID") int id);//更新Booksint updateBook(Book books);//根据id查询BookBook queryBookByID(@Param("bookID") int id);//查看全部的BookList<Book> queryAllBook();}
- 在Maven中导入Mybatis所需要的驱动包(mybatis),代码如下:
<!-- MyBatis --><dependency><groupId>org.mybatis</groupId><artifactId>mybatis</artifactId><version>3.4.6</version></dependency>
- 在dao包下编写对应的映射文件BookMapper.xml,代码如下:
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapperPUBLIC "-//mybatis.org//DTD Config 3.0//EN""http://mybatis.org/dtd/mybatis-3-mapper.dtd"><mapper namespace="dao.BookDao"><!--//增加一个Books--><insert id="addBook" parameterType="Book">insert into ssmbuild.books(bookID , bookName, bookCounts, detail)values (#{bookID},#{bookName},#{bookCounts},#{detail})</insert><!--//根据id删除Books--><delete id="deleteBookByID" parameterType="int">delete from ssmbuild.books where bookID = #{bookID}</delete><!--//更新Books--><update id="updateBook" parameterType="Book">update ssmbuild.booksset bookName = #{bookName} , bookCounts = #{bookCounts} ,detail = #{detail}where bookID = #{bookID}</update><!--//根据id查询Book--><select id="queryBookByID" resultType="Book">select * from ssmbuild.books where bookID = #{bookID}</select><!--//查看全部的Book--><select id="queryAllBook" resultType="Book">select * from ssmbuild.books</select></mapper>
- 在resources目录下编写Mybatis的配置文件Mybatis-config.xml,用于配置别名,以及注册映射文件,代码如下:
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configurationPUBLIC "-//mybatis.org//DTD Config 3.0//EN""http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration><typeAliases><package name="pojo"/></typeAliases><mappers><mapper resource="dao/BookMapper.xml"></mapper></mappers></configuration>
4.实现service层
- 在项目的java目录下新建service包,编写service层接口BookService,代码如下所示:
package service;import org.apache.ibatis.annotations.Param;
import pojo.Book;import java.util.List;public interface BookService {//增加一个Booksint addBook(Book books);//根据id删除Booksint deleteBookByID( @Param("bookID") int id);//更新Booksint updateBook(Book books);//根据id查询BookBook queryBookByID(@Param("bookID") int id);//查看全部的BookList<Book> queryAllBook();}
- 在service包下编写对应的实现类BookServiceImpl,代码如下:
package service;import dao.BookDao;
import pojo.Book;import java.util.List;public class BookServiceImpl implements BookService{// 组合private BookDao bookDao;public void setBookDao(BookDao bookDao) {this.bookDao = bookDao;}@Overridepublic int addBook(Book books) {return bookDao.addBook(books);}@Overridepublic int deleteBookByID(int id) {return bookDao.deleteBookByID(id);}@Overridepublic int updateBook(Book books) {return bookDao.updateBook(books);}@Overridepublic Book queryBookByID(int id) {return bookDao.queryBookByID(id);}@Overridepublic List<Book> queryAllBook() {return bookDao.queryAllBook();}
}
5.配置Spring整合dao层
- 在本例中使用c3p0连接池,需要在Maven导入相关的包,代码如下:
<!-- 数据库连接池 --><dependency><groupId>com.mchange</groupId><artifactId>c3p0</artifactId><version>0.9.5.2</version></dependency><!-- mybatis-spring整合包 --><dependency><groupId>org.mybatis</groupId><artifactId>mybatis-spring</artifactId><version>1.3.1</version></dependency><!--Spring相关包--><dependency><groupId>org.springframework</groupId><artifactId>spring-jdbc</artifactId><version>4.3.24.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-webmvc</artifactId><version>4.3.24.RELEASE</version></dependency>
- 在resources目录下新建spring文件夹,并在该文件夹中新建一个名为spring-dao.xml的配置文件,用于让Spring整合mybatis,代码如下:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:context="http://www.springframework.org/schema/context"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context.xsd"><!--整合Mybatis--><!--1.关联数据库文件--><context:property-placeholder location="classpath:database.properties"/><!--2.数据库连接池--><bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"><!--数据库的基本配置--><property name="driverClass" value="${jdbc.driver}"/><property name="jdbcUrl" value="${jdbc.url}"/><property name="user" value="${jdbc.username}"/><property name="password" value="${jdbc.password}"/></bean><!--3.sqlSessionFactory--><bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"><property name="dataSource" ref="dataSource"/><!--关联mybatis--><property name="configLocation" value="classpath:mybatis-config.xml"/></bean><!--4.注册dao层Bean--><!--动态实现dao接口注入Spring容器中--><bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"><!--绑定sqlSessionFactory--><property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/><!--扫描包--><property name="basePackage" value="dao"/></bean><!--5.扫描包--><context:component-scan base-package="dao"/></beans>
6.配置Spring整合service层
在resources/spring文件夹中新建一个名为spring-service.xml的配置文件,用于让Spring整合service层,代码如下:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:context="http://www.springframework.org/schema/context"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context.xsd"><!--1.扫描包--><context:component-scan base-package="service"/><!--2.手动配置bean--><bean id="bookServiceImpl" class="service.BookServiceImpl"><property name="bookDao" ref="bookDao"/></bean><!--3.事务管理--><bean class="org.springframework.jdbc.datasource.DataSourceTransactionManager"><!--数据源--><property name="dataSource" ref="dataSource"/></bean></beans>
7.配置Spring整合Spring MVC
- 修改webapp目录下的web.xml文件,代码如下:
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns="http://java.sun.com/xml/ns/javaee"xsi:schemaLocation="http://java.sun.com/xml/ns/javaeehttp://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"id="WebApp_ID" version="3.0"><!--1.DispatchServlet--><servlet><servlet-name>springmvc</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><!--关联Spring配置文件--><init-param><param-name>contextConfigLocation</param-name><param-value>classpath:applicationContext.xml</param-value></init-param><load-on-startup>1</load-on-startup></servlet><servlet-mapping><servlet-name>springmvc</servlet-name><url-pattern>/</url-pattern></servlet-mapping><!--2.字符编码过滤--><!--字符编码过滤--><filter><filter-name>encodingFilter</filter-name><!--<filter-class>com.kuang.filter.GenericEncodingFilter</filter-class>--><filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class><!--参数:CharacterEncodingFilter--><init-param><param-name>encoding</param-name><param-value>utf-8</param-value></init-param></filter><filter-mapping><filter-name>encodingFilter</filter-name><url-pattern>/*</url-pattern></filter-mapping></web-app>
- 在resources/spring文件夹中新建一个名为spring-mvc.xml的配置文件,用于让Spring整合servlet层,代码如下:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:context="http://www.springframework.org/schema/context"xmlns:mvc="http://www.springframework.org/schema/mvc"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context.xsdhttp://www.springframework.org/schema/mvchttp://www.springframework.org/schema/mvc/spring-mvc.xsd"><!--1.扫描包--><context:component-scan base-package="controller"/><!--2.静态资源过滤--><mvc:default-servlet-handler/><!--3.注解驱动--><mvc:annotation-driven/><!--4.视图解析器--><bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"><property name="prefix" value="/WEB-INF/jsp/"/><property name="suffix" value=".jsp"/></bean></beans>
- 在目录中新建一个名为filter的包,在包中新建名为GenericEncodingFilter的类,用于字符编码过滤,代码如下:
package filter;import javax.servlet.*;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletRequestWrapper;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.io.UnsupportedEncodingException;
import java.util.Map;/*** 解决get和post请求 全部乱码的过滤器*/
public class GenericEncodingFilter implements Filter {@Overridepublic void destroy() {}@Overridepublic void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {//处理response的字符编码HttpServletResponse myResponse=(HttpServletResponse) response;myResponse.setContentType("text/html;charset=UTF-8");// 转型为与协议相关对象HttpServletRequest httpServletRequest = (HttpServletRequest) request;// 对request包装增强HttpServletRequest myrequest = new MyRequest(httpServletRequest);chain.doFilter(myrequest, response);}@Overridepublic void init(FilterConfig filterConfig) throws ServletException {}}//自定义request对象,HttpServletRequest的包装类
class MyRequest extends HttpServletRequestWrapper {private HttpServletRequest request;//是否编码的标记private boolean hasEncode;//定义一个可以传入HttpServletRequest对象的构造函数,以便对其进行装饰public MyRequest(HttpServletRequest request) {super(request);// super必须写this.request = request;}// 对需要增强方法 进行覆盖@Overridepublic Map getParameterMap() {// 先获得请求方式String method = request.getMethod();if (method.equalsIgnoreCase("post")) {// post请求try {// 处理post乱码request.setCharacterEncoding("utf-8");return request.getParameterMap();} catch (UnsupportedEncodingException e) {e.printStackTrace();}} else if (method.equalsIgnoreCase("get")) {// get请求Map<String, String[]> parameterMap = request.getParameterMap();if (!hasEncode) { // 确保get手动编码逻辑只运行一次for (String parameterName : parameterMap.keySet()) {String[] values = parameterMap.get(parameterName);if (values != null) {for (int i = 0; i < values.length; i++) {try {// 处理get乱码values[i] = new String(values[i].getBytes("ISO-8859-1"), "utf-8");} catch (UnsupportedEncodingException e) {e.printStackTrace();}}}}hasEncode = true;}return parameterMap;}return super.getParameterMap();}//取一个值@Overridepublic String getParameter(String name) {Map<String, String[]> parameterMap = getParameterMap();String[] values = parameterMap.get(name);if (values == null) {return null;}return values[0]; // 取回参数的第一个值}//取所有值@Overridepublic String[] getParameterValues(String name) {Map<String, String[]> parameterMap = getParameterMap();String[] values = parameterMap.get(name);return values;}
}
8.配置Spring整合文件
- 在resources中新建一个名为applicationContext.xml的配置文件,用于整合上面的spring-dao.xml、spring-service.xml、spring-mvc.xml,代码如下:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans.xsd"><!--整合Spring--><import resource="classpath:spring/spring-dao.xml"/><import resource="classpath:spring/spring-service.xml"/><import resource="classpath:spring/spring-mvc.xml"/></beans>
- 在Maven导入jsp和servlet的包,代码如下:
<dependency><groupId>javax.servlet</groupId><artifactId>javax.servlet-api</artifactId><version>3.0.1</version><scope>provided</scope></dependency><dependency><groupId>javax.servlet.jsp</groupId><artifactId>jsp-api</artifactId><version>2.2</version><scope>provided</scope></dependency><dependency><groupId>javax.servlet</groupId><artifactId>jstl</artifactId><version>1.2</version></dependency>
9.实现controller层
在项目的java目录下新建controller包,编写控制器BookController,代码如下所示:
package controller;import org.apache.ibatis.annotations.Param;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import pojo.Book;
import service.BookService;import java.util.List;@Controller
@RequestMapping("/book")
public class BookController {@Autowired@Qualifier("bookServiceImpl")private BookService bookService;// 展示全部的书籍@RequestMapping("/allBook")public String list(Model model){List<Book> list = bookService.queryAllBook();model.addAttribute("list",list);return "allBook";}// 跳转到新增书籍页面@RequestMapping("/toAddBook")public String toAddBookPage(){return "addBook";}// 增加书籍@RequestMapping("/addBook")public String addBook(Book book){bookService.addBook(book);return "redirect:/book/allBook";}// 跳转到修改书籍页面@RequestMapping("/toUpdateBook")public String toUpdateBook(int id,Model model){Book book = bookService.queryBookByID(id);model.addAttribute("book",book);return "updateBook";}// 修改书籍@RequestMapping("/updateBook")public String updateBook(Book book,Model model){bookService.updateBook(book);// 更新最新的书籍Book book1 = bookService.queryBookByID(book.getBookID());model.addAttribute("books",book1);return "redirect:/book/allBook";}// 删除书籍,使用Restful风格@RequestMapping("/del/{bookID}")public String delete(@PathVariable("bookID") int id){bookService.deleteBookByID(id);return "redirect:/book/allBook";}
}
10.实现view层
- 编写主页index.jsp,用于进入查看所有图书的页面,代码如下:
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8" %>
<!DOCTYPE HTML>
<html>
<head><title>首页</title><style type="text/css">a {text-decoration: none;color: black;font-size: 18px;}h3 {width: 180px;height: 38px;margin: 100px auto;text-align: center;line-height: 38px;background: deepskyblue;border-radius: 4px;}</style>
</head>
<body><h3><a href="${pageContext.request.contextPath}/book/allBook">点击进入列表页</a>
</h3>
</body>
</html>
- 在WEB-INF目录下新建jsp目录,并在该目录下编写allBook.jsp,用于查看所有图书,代码如下:
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head><title>书籍列表</title><meta name="viewport" content="width=device-width, initial-scale=1.0"><!-- 引入 Bootstrap --><link href="https://cdn.bootcss.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet">
</head>
<body><div class="container"><div class="row clearfix"><div class="col-md-12 column"><div class="page-header"><h1><small>书籍列表 —— 显示所有书籍</small></h1></div></div></div><div class="row"><div class="col-md-4 column"><a class="btn btn-primary" href="${pageContext.request.contextPath}/book/toAddBook">新增</a></div></div><div class="row clearfix"><div class="col-md-12 column"><table class="table table-hover table-striped"><thead><tr><th>书籍编号</th><th>书籍名字</th><th>书籍数量</th><th>书籍详情</th><th>操作</th></tr></thead><tbody><c:forEach var="book" items="${requestScope.get('list')}"><tr><td>${book.getBookID()}</td><td>${book.getBookName()}</td><td>${book.getBookCounts()}</td><td>${book.getDetail()}</td><td><a href="${pageContext.request.contextPath}/book/toUpdateBook?id=${book.getBookID()}">更改</a> |<a href="${pageContext.request.contextPath}/book/del/${book.getBookID()}">删除</a></td></tr></c:forEach></tbody></table></div></div>
</div>
- 在WEB-INF/jsp目录下编写addBook.jsp,用于添加图书,代码如下:
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ page contentType="text/html;charset=UTF-8" language="java" %><html>
<head><title>新增书籍</title><meta name="viewport" content="width=device-width, initial-scale=1.0"><!-- 引入 Bootstrap --><link href="https://cdn.bootcss.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet">
</head>
<body>
<div class="container"><div class="row clearfix"><div class="col-md-12 column"><div class="page-header"><h1><small>新增书籍</small></h1></div></div></div><form action="${pageContext.request.contextPath}/book/addBook" method="post">书籍名称:<input type="text" name="bookName"><br><br><br>书籍数量:<input type="text" name="bookCounts"><br><br><br>书籍详情:<input type="text" name="detail"><br><br><br><input type="submit" value="添加"></form></div>
- 在WEB-INF/jsp目录下编写updateBook.jsp,用于添加图书,代码如下:
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head><title>修改信息</title><meta name="viewport" content="width=device-width, initial-scale=1.0"><!-- 引入 Bootstrap --><link href="https://cdn.bootcss.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet">
</head>
<body>
<div class="container"><div class="row clearfix"><div class="col-md-12 column"><div class="page-header"><h1><small>修改信息</small></h1></div></div></div><form action="${pageContext.request.contextPath}/book/updateBook" method="post"><input type="hidden" name="bookID" value="${book.getBookID()}"/>书籍名称:<input type="text" name="bookName" value="${book.getBookName()}"/>书籍数量:<input type="text" name="bookCounts" value="${book.getBookCounts()}"/>书籍详情:<input type="text" name="detail" value="${book.getDetail() }"/><input type="submit" value="提交"/></form></div>
11.运行前检查
- Maven的包导入应如下所示(注意添加build标签中的resources标签,该标签用于让Maven导入相关资源):
<?xml version="1.0" encoding="UTF-8"?><project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><groupId>com.moxitao</groupId><artifactId>SSMbuild-test</artifactId><version>1.0-SNAPSHOT</version><packaging>war</packaging><name>SSMbuild-test Maven Webapp</name><!-- FIXME change it to the project's website --><url>http://www.example.com</url><properties><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding><maven.compiler.source>1.7</maven.compiler.source><maven.compiler.target>1.7</maven.compiler.target></properties><dependencies><!--junit部分--><!--测试模块单元--><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>4.11</version><scope>test</scope></dependency><!--Mybatis部分--><!--数据库驱动包--><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>5.1.47</version></dependency><!--mybatis的包--><dependency><groupId>org.mybatis</groupId><artifactId>mybatis</artifactId><version>3.4.6</version></dependency><!--Mybatis部分完结--><!--Spring部分--><!--mybatis-srping整合包--><dependency><groupId>org.mybatis</groupId><artifactId>mybatis-spring</artifactId><version>1.3.1</version></dependency><!--第三方数据源:c3p0--><dependency><groupId>com.mchange</groupId><artifactId>c3p0</artifactId><version>0.9.5.2</version></dependency><!--Spring相关的--><dependency><groupId>org.springframework</groupId><artifactId>spring-webmvc</artifactId><version>4.3.24.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-jdbc</artifactId><version>4.3.24.RELEASE</version></dependency><!--Spring部分完结--><!--SpringMVC部分--><!--servlet--><dependency><groupId>javax.servlet</groupId><artifactId>javax.servlet-api</artifactId><version>3.0.1</version></dependency><!--jsp--><dependency><groupId>javax.servlet.jsp</groupId><artifactId>jsp-api</artifactId><version>2.2</version></dependency><!--jstl--><dependency><groupId>javax.servlet</groupId><artifactId>jstl</artifactId><version>1.2</version></dependency></dependencies><!--SpringMVC部分完结--><build><finalName>SSMbuild-test</finalName><pluginManagement><!-- lock down plugins versions to avoid using Maven defaults (may be moved to parent pom) --><plugins><plugin><artifactId>maven-clean-plugin</artifactId><version>3.1.0</version></plugin><!-- see http://maven.apache.org/ref/current/maven-core/default-bindings.html#Plugin_bindings_for_war_packaging --><plugin><artifactId>maven-resources-plugin</artifactId><version>3.0.2</version></plugin><plugin><artifactId>maven-compiler-plugin</artifactId><version>3.8.0</version></plugin><plugin><artifactId>maven-surefire-plugin</artifactId><version>2.22.1</version></plugin><plugin><artifactId>maven-war-plugin</artifactId><version>3.2.2</version></plugin><plugin><artifactId>maven-install-plugin</artifactId><version>2.5.2</version></plugin><plugin><artifactId>maven-deploy-plugin</artifactId><version>2.8.2</version></plugin></plugins></pluginManagement><resources><resource><directory>src/main/java</directory><includes><include>**/*.xml</include></includes><filtering>false</filtering></resource><resource><directory>src/main/resources</directory><includes><include>**/*.xml</include><include>**/*.properties</include></includes><filtering>false</filtering></resource></resources></build>
</project>
- 项目目录如图所示:
运行
配置好Tomcat运行环境后,即可开始运行,结果图如下:
- 首页(index.jsp)
- 显示全部书籍(allBook.jsp)
- 增加书籍页面(addBook.jsp)
- 修改书籍页面(updateBook.jsp)
后记
尽管现在的Java Web项目的开发多用Spring Boot进行搭建,但是使用相对原生的SSM(Spring + Spring MVC + Mybatis)进行开发,不仅能让我们对于Web项目的搭建流程更加熟悉,还会对我们在日后的学习和工作中大有裨益
项目的源码地址:SSM版本 简易管理系统,由于该博客之前有一些细节错误尚未修正,这里在搭建项目的时候进行了部分修改。对按照该博客搭建项目后遇到坑的读者表示抱歉,感谢您的浏览!
