在web开发中，经常会使用到编辑器进行图文内容的编辑，个人推荐使用xheditor，如你所见，CSDN也正是使用的xheditor。

一，首先创建一个web工程：test-xheditor；具体目录结构如下：
二，按上图，导入相应的xheditor文件、lib包【commons-fileupload-1.2.1.jar，commons-io-1.3.2.jar，
commons-lang-2.4.jar，servlet-api.jar】、index.jsp。
三，系统常量类：SystemConstants.class，
/**
*
*/
package com.xheditor.contants;
/**
* @author hu.shiguo
* @time 2014-3-19下午11:57:14
* @description 系统常量
* @version
*/
public class SystemConstants {
public static String WEB_ROOT = null;
}
四，初始化配置类：SystemListener.class，
/**
*
*/
package com.xheditor.listener;
import javax.servlet.ServletContextEvent;
import javax.servlet.ServletContextListener;
import com.xheditor.contants.SystemConstants;
/**
* @author hu.shiguo
* @time 2014-3-19下午11:50:36
* @description 系统加载监听器，可以在web容器启动的时候加载一些配置到内存中
* @version
*/
public class SystemListener implements ServletContextListener {
/* (non-Javadoc)
* @see javax.servlet.ServletContextListener#contextDestroyed(javax.servlet.ServletContextEvent)
*/
@Override
public void contextDestroyed(ServletContextEvent event) {
}
/* (non-Javadoc)
* @see javax.servlet.ServletContextListener#contextInitialized(javax.servlet.ServletContextEvent)
*/
@Override
public void contextInitialized(ServletContextEvent event) {
String webRoot = event.getServletContext().getRealPath("/");
System.out.println(webRoot);
SystemConstants.WEB_ROOT = webRoot;
}
}
五，上传文件类：UploadFileServlet.class，
package com.sportevents.servlet;
import java.io.File;
import java.io.IOException;
import java.io.PrintWriter;
import java.io.Serializable;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.HashMap;
import java.util.Iterator;
import java.util.List;
import java.util.Map;
import java.util.UUID;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.commons.fileupload.DiskFileUpload;
import org.apache.commons.fileupload.FileItem;
import org.apache.commons.lang.StringUtils;
import com.sportevents.contants.SystemConstants;
@SuppressWarnings({ "serial", "deprecation" })
public class UploadFileServlet extends HttpServlet {
private static String baseFileDir = File.separator + "uploadFile" + File.separator;//上传文件存储目录
private static String baseURLDir = "/uploadFile/";//上传文件目录URL
private static String fileExt = "jpg,jpeg,bmp,gif,png";
private static Long maxSize = 0l;
// 0:不建目录 1:按天存入目录 2:按月存入目录 3:按扩展名存目录 建议使用按天存
private static String dirType = "1";
/**
* 文件上传初始化工作
*/
public void init() throws ServletException {
/*获取文件上传存储的相当路径*/
if (!StringUtils.isBlank(this.getInitParameter("baseDir"))){
baseFileDir = this.getInitParameter("baseDir");
}
String realBaseDir = this.getServletConfig().getServletContext().getRealPath(baseFileDir);
File baseFile = new File(realBaseDir);
if (!baseFile.exists()) {
baseFile.mkdir();
}
/*获取文件类型参数*/
fileExt = this.getInitParameter("fileExt");

/*获取文件大小参数*/
String maxSize_str = this.getInitParameter("maxSize");
if (StringUtils.isNotBlank(maxSize_str)) maxSize = new Long(maxSize_str);
/*获取文件目录类型参数*/
dirType = this.getInitParameter("dirType");
if (StringUtils.isBlank(dirType))
dirType = "1";
if (",0,1,2,3,".indexOf("," + dirType + ",") < 0)
dirType = "1";
}
/**
* 上传文件数据处理过程
*/
@SuppressWarnings({"unchecked" })
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html; charset=UTF-8");
response.setHeader("Cache-Control", "no-cache");
String err = "";
String newFileName = "";
DiskFileUpload upload = new DiskFileUpload();
try {
List<FileItem> items = upload.parseRequest(request);
Map<String, Serializable> fields = new HashMap<String, Serializable>();
Iterator<FileItem> iter = items.iterator();
while (iter.hasNext()) {
FileItem item = (FileItem) iter.next();
if (item.isFormField())
fields.put(item.getFieldName(), item.getString());
else
fields.put(item.getFieldName(), item);
}
/*获取表单的上传文件*/
FileItem uploadFile = (FileItem)fields.get("filedata");
/*获取文件上传路径名称*/
String fileNameLong = uploadFile.getName();
System.out.println("fileNameLong:" + fileNameLong);
/*获取文件扩展名*/
/*索引加1的效果是只取xxx.jpg的jpg*/
String extensionName = fileNameLong.substring(fileNameLong.lastIndexOf(".") + 1);
System.out.println("extensionName:" + extensionName);
/*检查文件类型*/
if (("," + fileExt.toLowerCase() + ",").indexOf("," + extensionName.toLowerCase() + ",") < 0){
printInfo(response, "不允许上传此类型的文件", "");
return;
}
/*文件是否为空*/
if (uploadFile.getSize() == 0){
printInfo(response, "上传文件不能为空", "");
return;
}
/*检查文件大小*/
if (maxSize > 0 && uploadFile.getSize() > maxSize){
printInfo(response, "上传文件的大小超出限制", "");
return;
}
//0:不建目录, 1:按天存入目录, 2:按月存入目录, 3:按扩展名存目录.建议使用按天存.
String fileFolder = "";
if (dirType.equalsIgnoreCase("1"))
fileFolder = new SimpleDateFormat("yyyyMMdd").format(new Date());;
if (dirType.equalsIgnoreCase("2"))
fileFolder = new SimpleDateFormat("yyyyMM").format(new Date());
if (dirType.equalsIgnoreCase("3"))
fileFolder = extensionName.toLowerCase();
//工程目录
String projectPath = SystemConstants.WEB_ROOT;
File files = new File(projectPath);
//上传文件保存目录
String uploadFilePath = files.getParent()+File.separator + "uploadFile"+File.separator
+fileFolder+File.separator;
//String uploadFilePath =files.getPath()+File.separator + "uploadFile";
/*文件存储的相对路径*/
//String saveDirPath = baseFileDir + fileFolder + "/";
//System.out.println("saveDirPath:" + saveDirPath);
/*文件存储在容器中的绝对路径*/
//String saveFilePath = this.getServletConfig().getServletContext().getRealPath("") + baseFileDir + fileFolder + "/";
System.out.println("saveFilePath:" + uploadFilePath);
/*构建文件目录以及目录文件*/
File fileDir = new File(uploadFilePath);
if (!fileDir.exists()) {fileDir.mkdirs();}
/*重命名文件*/
String filename = UUID.randomUUID().toString();
File savefile = new File(uploadFilePath + filename + "." + extensionName);
/*存储上传文件*/
System.out.println(upload == null);
uploadFile.write(savefile);
//String projectBasePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+request.getContextPath();
String projectBasePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort();
newFileName = projectBasePath + baseURLDir + fileFolder + "/" + filename + "." + extensionName;
System.out.println("newFileName:" + newFileName);
} catch (Exception ex) {
System.out.println(ex.getMessage());
newFileName = "";
err = "错误: " + ex.getMessage();
}
printInfo(response, err, newFileName);
}
/**
* 使用I/O流输出 json格式的数据
* @param response
* @param err
* @param newFileName
* @throws IOException
*/
public void printInfo(HttpServletResponse response, String err, String newFileName) throws IOException {
PrintWriter out = response.getWriter();
//String filename = newFileName.substring(newFileName.lastIndexOf("/") + 1);
out.println("{\"err\":\"" + err + "\",\"msg\":\"" + newFileName + "\"}");
out.flush();
out.close();
}
}
六，web.xml,主要配置监听和上传文件的servlet
<listener>
<listener-class>com.xheditor.listener.SystemListener</listener-class>
</listener>
<servlet>
<servlet-name>UploadFileServlet</servlet-name>
<servlet-class>com.xheditor.servlet.UploadFileServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>UploadFileServlet</servlet-name>
<url-pattern>/servlet/UploadFileServlet</url-pattern>
</servlet-mapping>七，jsp页面：
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<c:set var="ctx" value="${pageContext.request.contextPath}" />
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
