1. 下载

CKFinder官网下载地址提供了PHP，ASP, Java等不同下载版本。

2. 配置

1）config.xml放到WEB-INF下，

2）其他文件放到Webcontent下，

3）配置web.xml,

xml<!--CKFinder  --><servlet><servlet-name>ConnectorServlet</servlet-name><servlet-class>com.ckfinder.connector.ConnectorServlet</servlet-class><init-param><param-name>XMLConfig</param-name><param-value>/WEB-INF/ckfinder.xml</param-value></init-param><init-param><param-name>debug</param-name><param-value>false</param-value></init-param><load-on-startup>1</load-on-startup></servlet><servlet-mapping><servlet-name>ConnectorServlet</servlet-name><url-pattern><!--根据ckfinder文件所在文件夹决定，我的ckfinder放到webcontent下的view文件夹下-->/view/ckfinder/core/connector/java/connector.java</url-pattern></servlet-mapping><filter><filter-name>FileUploadFilter</filter-name><filter-class>com.ckfinder.connector.FileUploadFilter</filter-class><init-param><param-name>sessionCookieName</param-name><param-value>JSESSIONID</param-value></init-param><init-param><param-name>sessionParameterName</param-name><param-value>jsessionid</param-value></init-param></filter><filter-mapping><filter-name>FileUploadFilter</filter-name><url-pattern><!--根据ckfinder文件所在文件夹决定，我的ckfinder放到webcontent下的view文件夹下-->/view/ckfinder/core/connector/java/connector.java</url-pattern></filter-mapping><!-- Userfiles download --><servlet><servlet-name>UserfilesDownloadServlet</servlet-name><!--文件下载需要对应后台的Servlet--><servlet-class>com.ckfinder.UserfilesDownloadServlet</servlet-class></servlet><servlet-mapping><servlet-name>UserfilesDownloadServlet</servlet-name><!--此处由config.xml的baseURl决定路径--><url-pattern>/userfiles/*</url-pattern></servlet-mapping>

4) 配置config.xml

xml<config><enabled>true</enabled><baseDir></baseDir><baseURL>/userfiles/</baseURL><licenseKey></licenseKey><licenseName></licenseName><imgWidth>1024</imgWidth><imgHeight>768</imgHeight><imgQuality>80</imgQuality><uriEncoding>UTF-8</uriEncoding><forceASCII>false</forceASCII><disallowUnsafeCharacters>false</disallowUnsafeCharacters><userRoleSessionVar>CKFinder_UserRole</userRoleSessionVar><checkDoubleExtension>true</checkDoubleExtension><checkSizeAfterScaling>true</checkSizeAfterScaling><secureImageUploads>true</secureImageUploads><htmlExtensions>html,htm,xml,js</htmlExtensions><hideFolders><folder>.svn</folder><folder>CVS</folder></hideFolders><hideFiles><file>.*</file></hideFiles><defaultResourceTypes></defaultResourceTypes><types><type name="Files"><!--java-util是我的项目工程名--><url>/java-util%BASE_URL%files/</url><directory>%BASE_DIR%files</directory><maxSize>5M</maxSize><allowedExtensions>7z,aiff,asf,avi,bmp,csv,doc,docx,fla,flv,gif,gz,gzip,jpeg,jpg,mid,mov,mp3,mp4,mpc,mpeg,mpg,ods,odt,pdf,png,ppt,pptx,pxd,qt,ram,rar,rm,rmi,rmvb,rtf,sdc,sitd,swf,sxc,sxw,tar,tgz,tif,tiff,txt,vsd,wav,wma,wmv,xls,xlsx,zip</allowedExtensions><deniedExtensions></deniedExtensions></type><type name="Images"><url>%BASE_URL%images/</url><directory>%BASE_DIR%images</directory><maxSize>0</maxSize><allowedExtensions>bmp,gif,jpeg,jpg,png</allowedExtensions><deniedExtensions></deniedExtensions></type><type name="Flash"><url>%BASE_URL%flash/</url><directory>%BASE_DIR%flash</directory><maxSize>0</maxSize><allowedExtensions>swf,flv</allowedExtensions><deniedExtensions></deniedExtensions></type></types><accessControls><accessControl><role>*</role><resourceType>*</resourceType><folder>/</folder><folderView>true</folderView><folderCreate>true</folderCreate><folderRename>true</folderRename><folderDelete>true</folderDelete><fileView>true</fileView><fileUpload>true</fileUpload><fileRename>true</fileRename><fileDelete>true</fileDelete></accessControl></accessControls><thumbs><enabled>true</enabled><url>%BASE_URL%_thumbs/</url><directory>%BASE_DIR%_thumbs</directory><directAccess>false</directAccess><maxHeight>100</maxHeight><maxWidth>200</maxWidth><quality>80</quality></thumbs><plugins><plugin><name>imageresize</name><class>com.ckfinder.connector.plugins.ImageResize</class><params><param name="smallThumb" value="90x90"></param><param name="mediumThumb" value="120x120"></param><param name="largeThumb" value="180x180"></param></params></plugin><plugin><name>fileeditor</name><class>com.ckfinder.connector.plugins.FileEditor</class><params></params></plugin></plugins><basePathBuilderImpl>com.ckfinder.connector.configuration.ConfigurationPathBuilder</basePathBuilderImpl>
</config>

5）后台下载文件需要的Servlet

import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.UnsupportedEncodingException;import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;

import javax.servlet.http.HttpServletResponse;import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.util.FileCopyUtils;
import org.springframework.web.util.UriUtils;import com.ckfinder.connector.ServletContextFactory;/*** 查看CK上传的图片* @author ThinkGem* @version 2014-06-25*/
public class UserfilesDownloadServlet extends HttpServlet {private static final long serialVersionUID = 1L;private Logger logger = LoggerFactory.getLogger(getClass());private String USERFILES_BASE_URL = "/userfiles/";public void fileOutputStream(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {String filepath = req.getRequestURI();int index = filepath.indexOf(USERFILES_BASE_URL);if(index >= 0) {filepath = filepath.substring(index + USERFILES_BASE_URL.length());}try {filepath = UriUtils.decode(filepath, "UTF-8");} catch (UnsupportedEncodingException e1) {logger.error(String.format("解释文件路径失败，URL地址为%s", filepath), e1);}File file = new File(getUserfilesBaseDir() + USERFILES_BASE_URL + filepath);try {FileCopyUtils.copy(new FileInputStream(file), resp.getOutputStream());resp.setHeader("Content-Type", "application/octet-stream");return;} catch (FileNotFoundException e) {req.setAttribute("exception", new FileNotFoundException("请求的文件不存在"));req.getRequestDispatcher("/WEB-INF/views/error/404.jsp").forward(req, resp);}}private String getUserfilesBaseDir() {String path = "";try {path = ServletContextFactory.getServletContext().getRealPath("/");} catch (Exception e) {e.printStackTrace();}return path;}@Overrideprotected void doGet(HttpServletRequest req, HttpServletResponse resp)throws ServletException, IOException {fileOutputStream(req, resp);}@Overrideprotected void doPost(HttpServletRequest req, HttpServletResponse resp)throws ServletException, IOException {fileOutputStream(req, resp);}
}

6) jar包引入
方法一：pom.xml
