SSM框架整合

article/2025/9/20 8:44:09

今天来整合一下SSM三大框架~~

1、创建一个maven项目

比较简单就不赘述了，创建的时候选择webapp骨架。

用骨架创建的项目，在创建完之后要更新一下web.xml
模板目录：“你的Tomcat安装目录\webapps\ROOT\WEB-INF\web.xml”

2、项目整体结构

按照以下项目目录创建好项目的结构
在这里插入图片描述

3、导入依赖

<dependencies><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>8.0.29</version></dependency><dependency><groupId>org.mybatis</groupId><artifactId>mybatis</artifactId><version>3.5.10</version></dependency><dependency><groupId>org.mybatis</groupId><artifactId>mybatis-spring</artifactId><version>2.0.7</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-jdbc</artifactId><version>5.0.2.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-webmvc</artifactId><version>5.0.2.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-aop</artifactId><version>5.0.2.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-tx</artifactId><version>5.0.2.RELEASE</version></dependency><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>4.12</version></dependency><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId><version>1.18.24</version></dependency><dependency><groupId>log4j</groupId><artifactId>log4j</artifactId><version>1.2.17</version></dependency><dependency><groupId>com.alibaba</groupId><artifactId>druid</artifactId><version>1.2.11</version></dependency><dependency><groupId>javax.servlet</groupId><artifactId>servlet-api</artifactId><version>2.5</version><scope>provided</scope></dependency><dependency><groupId>javax.servlet.jsp</groupId><artifactId>jsp-api</artifactId><version>2.0</version><scope>provided</scope></dependency><dependency><groupId>jstl</groupId><artifactId>jstl</artifactId><version>1.2</version></dependency></dependencies>
<!--在build中加入如下代码，解决java文件夹下的xml文件加载不进来-->
<build><resources><resource><directory>src/main/java</directory><includes><include>**/*.properties</include><include>**/*.xml</include></includes></resource><resource><directory>src/main/resources</directory><includes><include>**/*.properties</include><include>**/*.xml</include></includes></resource></resources></build>

4、创建数据库表

/*
SQLyog Ultimate v12.09 (64 bit)
MySQL - 8.0.29 : Database - mybatis
*********************************************************************
*//*!40101 SET NAMES utf8 */;/*!40101 SET SQL_MODE=''*/;/*!40014 SET @OLD_UNIQUE_CHECKS=@@UNIQUE_CHECKS, UNIQUE_CHECKS=0 */;
/*!40014 SET @OLD_FOREIGN_KEY_CHECKS=@@FOREIGN_KEY_CHECKS, FOREIGN_KEY_CHECKS=0 */;
/*!40101 SET @OLD_SQL_MODE=@@SQL_MODE, SQL_MODE='NO_AUTO_VALUE_ON_ZERO' */;
/*!40111 SET @OLD_SQL_NOTES=@@SQL_NOTES, SQL_NOTES=0 */;
CREATE DATABASE /*!32312 IF NOT EXISTS*/`mybatis` /*!40100 DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci */ /*!80016 DEFAULT ENCRYPTION='N' */;USE `mybatis`;/*Table structure for table `blog` */DROP TABLE IF EXISTS `blog`;CREATE TABLE `blog` (`id` int NOT NULL AUTO_INCREMENT,`title` varchar(45) COLLATE utf8mb4_general_ci DEFAULT NULL,`author` varchar(45) COLLATE utf8mb4_general_ci DEFAULT NULL,`create_time` datetime DEFAULT NULL,`views` int DEFAULT NULL,PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=1012 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_general_ci;/*Data for the table `blog` */insert  into `blog`(`id`,`title`,`author`,`create_time`,`views`) values (1001,'java','寅子','2022-08-27 22:21:10',9999),(1002,'python','寅子','2022-08-27 22:22:07',9999),(1003,'c++','寅子','2022-08-27 22:22:37',9999),(1004,'c','寅子','2022-08-27 22:23:17',1000);/*!40101 SET SQL_MODE=@OLD_SQL_MODE */;
/*!40014 SET FOREIGN_KEY_CHECKS=@OLD_FOREIGN_KEY_CHECKS */;
/*!40014 SET UNIQUE_CHECKS=@OLD_UNIQUE_CHECKS */;
/*!40111 SET SQL_NOTES=@OLD_SQL_NOTES */;

5、创建pojo实体类

package com.yinzi.pojo;import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;import java.io.Serializable;
import java.util.Date;@Data
@AllArgsConstructor
@NoArgsConstructor
public class Blog implements Serializable {private int id;private String title;private String author;private Date createTime;private int views;
}

=============== 整合Mybatis ==============

6、编写mybatis配置文件：mybatis-config.xml

在mybatis-config中我们只配置基本的几个属性，剩下的有spring创建

<?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><settings><setting name="mapUnderscoreToCamelCase" value="true"/><setting name="logImpl" value="LOG4J"/></settings><typeAliases><package name="com.yinzi.pojo"/></typeAliases>
</configuration>

加入log4j日志配置

# Set root category priority to INFO and its only appender to CONSOLE.
#log4j.rootCategory=INFO, CONSOLE            debug   info   warn error fatal
log4j.rootCategory=debug, CONSOLE, LOGFILE# Set the enterprise logger category to FATAL and its only appender to CONSOLE.
log4j.logger.org.apache.axis.enterprise=FATAL, CONSOLE# CONSOLE is set to be a ConsoleAppender using a PatternLayout.
log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
log4j.appender.CONSOLE.layout.ConversionPattern=%d{ISO8601} %-6r [%15.15t] %-5p %30.30c %x - %m\n# LOGFILE is set to be a File appender using a PatternLayout.
log4j.appender.LOGFILE=org.apache.log4j.FileAppender
log4j.appender.LOGFILE.File=d:\axis.log
log4j.appender.LOGFILE.Append=true
log4j.appender.LOGFILE.layout=org.apache.log4j.PatternLayout
log4j.appender.LOGFILE.layout.ConversionPattern=%d{ISO8601} %-6r [%15.15t] %-5p %30.30c %x - %m\n

7、创建Spring整合mybatis的配置文件：spring-mybatis.xml

此配置主要用来整合mybatis

<?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/contexthttps://www.springframework.org/schema/context/spring-context.xsdhttp://www.springframework.org/schema/mvchttps://www.springframework.org/schema/mvc/spring-mvc.xsd"><bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource"><property name="driverClassName" value="com.mysql.cj.jdbc.Driver"/><property name="url" value="jdbc:mysql://localhost:3306/mybatis?useSSL=true&amp;useUnicode=true&amp;characterEncoding=utf8"/><property name="username" value="root"/><property name="password" value="123456"/></bean><bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"><property name="dataSource" ref="dataSource"/><property name="configLocation" value="classpath:mybatis-config.xml"/></bean><bean id="sqlSession" class="org.mybatis.spring.SqlSessionTemplate"><constructor-arg index="0" ref="sqlSessionFactory"/></bean><bean id="mapperScanner" class="org.mybatis.spring.mapper.MapperScannerConfigurer"><property name="basePackage" value="com.yinzi.dao"/></bean>
</beans>

8、创建dao中的BlogMapper接口和BlogMapper.xml

BlogMapper

package com.yinzi.dao;import com.yinzi.pojo.Blog;
import org.apache.ibatis.annotations.Param;import java.util.List;public interface BlogMapper {List<Blog> findAll();Blog findById(@Param("id") int id);List<Blog> findByTitle(@Param("title") String title);int add(Blog blog);int update(Blog blog);int delete(@Param("id") int id);}

BlogMapper.xml

<!DOCTYPE mapperPUBLIC "-//mybatis.org//DTD Mapper 3.0//EN""http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.yinzi.dao.BlogMapper"><cache/><select id="findAll" resultType="blog">select * from blog;</select><select id="findById" parameterType="int" resultType="blog">select * from blog where id = #{id};</select><select id="findByTitle" parameterType="String" resultType="blog">select * from blog<where>title like "%" #{title} "%";</where></select><insert id="add" parameterType="blog">insert into blog(title,author,create_time,views)values (#{title},#{author},#{createTime},#{views});</insert><update id="update" parameterType="blog">update blog set title=#{title},author=#{author},create_time=#{createTime},views=#{views}where id = #{id};</update><delete id="delete" parameterType="int">delete from blog where id = #{id};</delete>
</mapper>

9、创建service中的BlogService接口和BlogServiceImpl实现类

BlogService

package com.yinzi.service;import com.yinzi.pojo.Blog;
import org.apache.ibatis.annotations.Param;import java.util.List;public interface BlogService {List<Blog> findAll();Blog findById(int id);List<Blog> findByTitle(String title);int add(Blog blog);int update(Blog blog);int delete(int id);
}

BlogServiceImpl

package com.yinzi.service.impl;import com.yinzi.dao.BlogMapper;
import com.yinzi.pojo.Blog;
import com.yinzi.service.BlogService;import java.util.List;public class BlogServiceImpl implements BlogService {private BlogMapper blogMapper;public void setBlogMapper(BlogMapper blogMapper) {this.blogMapper = blogMapper;}@Overridepublic List<Blog> findAll() {return blogMapper.findAll();}@Overridepublic Blog findById(int id) {return blogMapper.findById(id);}@Overridepublic List<Blog> findByTitle(String title) {return blogMapper.findByTitle(title);}@Overridepublic int add(Blog blog) {return blogMapper.add(blog);}@Overridepublic int update(Blog blog) {return blogMapper.update(blog);}@Overridepublic int delete(int id) {return blogMapper.delete(id);}
}

10、创建Spring总的配置文件SpringContext.xml

<?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/contexthttps://www.springframework.org/schema/context/spring-context.xsdhttp://www.springframework.org/schema/mvchttps://www.springframework.org/schema/mvc/spring-mvc.xsd"><import resource="classpath:spring-mybatis.xml"/><import resource="classpath:spring-mvc.xml"/><bean id="blogService" class="com.yinzi.service.impl.BlogServiceImpl"><property name="blogMapper" ref="blogMapper"/></bean></beans>

这里的spring-mvc.xml时候springmvc的配置文件，防止这里爆红，可以先创建好，后面再进行编写

== 写到这里可以去测试一下项目的能不能运行起来 ==
创建一个Text测试类

import com.yinzi.pojo.Blog;
import com.yinzi.service.BlogService;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;import java.util.List;public class MyTest {@Testpublic void test1(){ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");BlogService blogService = context.getBean("blogService", BlogService.class);List<Blog> blogList = blogService.findAll();for (Blog blog : blogList) {System.out.println(blog);}}
}

如果以上配置没有错误，将得到一下输出，证明项目没有问题~
在这里插入图片描述

============ 整合SpringMVC =============

11、编写web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaeehttp://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"version="3.1"metadata-complete="true"><servlet><servlet-name>springmvc</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><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><filter><filter-name>characterEncoding</filter-name><filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class><init-param><param-name>encoding</param-name><param-value>utf-8</param-value></init-param></filter><filter-mapping><filter-name>characterEncoding</filter-name><url-pattern>/*</url-pattern></filter-mapping><filter><filter-name>HiddenHttpMethodFilter</filter-name><filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class></filter><filter-mapping><filter-name>HiddenHttpMethodFilter</filter-name><url-pattern>/*</url-pattern></filter-mapping>
</web-app>

12、创建spring-mvc.xml配置文件

<?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/contexthttps://www.springframework.org/schema/context/spring-context.xsdhttp://www.springframework.org/schema/mvchttps://www.springframework.org/schema/mvc/spring-mvc.xsd"><context:component-scan base-package="com.yinzi"><context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/></context:component-scan><bean id="internalResourceViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"><property name="prefix" value="/WEB-INF/pages/"/><property name="suffix" value=".jsp"/></bean><mvc:default-servlet-handler/><mvc:annotation-driven/></beans>

13、创建BlogController

package com.yinzi.controller;import com.yinzi.pojo.Blog;
import com.yinzi.service.BlogService;
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.*;import java.util.Date;
import java.util.List;@Controller
public class BlogController {@Autowired@Qualifier("blogService")private BlogService blogService;// 查询所有blog@GetMapping("/blog")public String findAll(Model model){List<Blog> blogList = blogService.findAll();model.addAttribute("blogList",blogList);return "blog";}// 跳转添加页面@RequestMapping("/toAdd")public String toAdd(){return "add";}// 添加blog@PostMapping("/blog")public String add(Blog blog){blog.setCreateTime(new Date());int add = blogService.add(blog);return "redirect:/blog";}@DeleteMapping("/blog/{id}")public String delete(@PathVariable int id){int delete = blogService.delete(id);return "redirect:/blog";}// 跳转修改页面@RequestMapping("/toUpdate/{id}")public String toUpdate(@PathVariable int id,Model model){Blog blog = blogService.findById(id);model.addAttribute("blog",blog);return "update";}// 修改blog@PutMapping("/blog")public String update(Blog blog){blog.setCreateTime(new Date());int update = blogService.update(blog);return "redirect:/blog";}// 根据名字查询blog@RequestMapping("/search")public String search(String title,Model model){List<Blog> blogList = blogService.findByTitle(title);model.addAttribute("blogList",blogList);return "blog";}
}

14、创建页面文件

分别在WEB-INF/pages/下创建一下jsp
blog.jsp

<%@ page contentType="text/html;charset=UTF-8" language="java" isELIgnored="false" %>
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
