说明：ueditor控件默认是把图片上传到默认的控件内部地址的，如果我们重新换包，图片肯定会清空。我们在开发的时候，肯定要将这个目录上传到固定的目录（文件服务器）中，防止被清空。
准备：1.我的工程(工程名为test)的服务器容器是本地的tomcat,本地目录：E:\apache-tomcat-7.4.44\webapps\test,端口为2022。
2.文件服务器是同一个tomcat下与工程名平级的目录里：E:\apache-tomcat-7.4.44\webapps\newsImg。也就是说直接访问（不用带工程名）这里面的图片可以的。
比如在该目录下新建abc.txt，重启tomcat，浏览器直接访问:http://localhost:2022/newsImg/abc.txt是可以直接访问的。
3.准备好了之后，下载ueditor控件（我的是jsp版本，后台是java的spring框架）地址：http://ueditor.baidu.com/website/download.html#ueditor
下载之后，直接放入工程的静态文件目录下，另外在jsp/lib目录下有jar包，需要移到工程的lib目录下
如图:
4.若改成文件存储的外部地址，则需要修改源码,其实就是改lib下面的ueditor-1.1.6.jar。源码的话，需要在网上找一下，我这边提供一下（下文给下载链接），即ueditor-jsp工程目录如下:在upload目录下添加UeditorActionEnter类：
在UeditorActionEnter的invoke方法中设置rootpath，即上传地址目录:
UeditorActionEnter类代码如下:
package com.baidu.ueditor.upload;
import com.baidu.ueditor.ActionEnter;
import com.baidu.ueditor.ConfigManager;
import com.baidu.ueditor.define.ActionMap;
import com.baidu.ueditor.define.BaseState;
import com.baidu.ueditor.define.State;
import com.baidu.ueditor.hunter.FileManager;
import com.baidu.ueditor.hunter.ImageHunter;
import com.baidu.ueditor.upload.Uploader;
import javax.servlet.http.HttpServletRequest;
import java.util.Map;
/**

public class UeditorActionEnter extends ActionEnter {
private HttpServletRequest request = null;
private String rootPath = null;
private String contextPath = null;
private String actionType = null;
private ConfigManager configManager = null;
public UeditorActionEnter(HttpServletRequest request, String rootPath) {
super(request, rootPath);
this.request = request;
this.rootPath = rootPath;
this.actionType = request.getParameter("action");
this.contextPath = request.getContextPath();
this.configManager = ConfigManager.getInstance(this.rootPath, this.contextPath, request.getRequestURI());
}
@Override
public String invoke() {
if (this.actionType != null && ActionMap.mapping.containsKey(this.actionType)) {
if (this.configManager != null && this.configManager.valid()) {
State state = null;
int actionCode = ActionMap.getType(this.actionType);
Map<String, Object> conf = null;
switch (actionCode) {
case 0:
return this.configManager.getAllConfig().toString();
case 1:
case 2:
case 3:
case 4:
conf = this.configManager.getConfig(actionCode);
//注意再这里修改rootPath和savePath，上传的实际路径为rootPath＋savePath
conf.put("rootPath", "E:/apache-tomcat-7.4.44/webapps/");
conf.put("savePath", conf.get("savePath"));
state = (new Uploader(this.request, conf)).doExec();
break;
case 5:
conf = this.configManager.getConfig(actionCode);
//注意再这里修改rootPath和savePath，上传的实际路径为rootPath＋savePath
conf.put("rootPath", "E:/apache-tomcat-7.4.44/webapps/");
conf.put("savePath", conf.get("savePath"));
String[] list = this.request.getParameterValues((String) conf.get("fieldName"));
state = (new ImageHunter(conf)).capture(list);
break;
case 6:
case 7:
conf = this.configManager.getConfig(actionCode);
//注意再这里修改rootPath和savePath，上传的实际路径为rootPath＋savePath
conf.put("rootPath", "E:/apache-tomcat-7.4.44/webapps/");
conf.put("savePath", conf.get("savePath"));
conf.put("dir", "/upload" + conf.get("dir"));
int start = this.getStartIndex();
state = (new FileManager(conf)).listFile(start);
}
return state.toJSONString();
} else {
return (new BaseState(false, 102)).toJSONString();
}
} else {
return (new BaseState(false, 101)).toJSONString();
}
}
}
在BinaryUploader类获取配置文件里配置的physicalPath变量：（这个physicalPath变量在后面配置文件中会讲）
BinaryUploader类全部代码:

import org.apache.commons.fileupload.disk.DiskFileItemFactory;
import org.apache.commons.fileupload.servlet.ServletFileUpload;
public class BinaryUploader {
public static void main(String[] args) {
System.out.println(null + "");
}
public static final State save(HttpServletRequest request,
Map<String, Object> conf) {
FileItemStream fileStream = null;
boolean isAjaxUpload = request.getHeader( "X_Requested_With" ) != null;
if (!ServletFileUpload.isMultipartContent(request)) {
return new BaseState(false, AppInfo.NOT_MULTIPART_CONTENT);
}
ServletFileUpload upload = new ServletFileUpload(
new DiskFileItemFactory());
if ( isAjaxUpload ) {
upload.setHeaderEncoding( "UTF-8" );
}
try {
FileItemIterator iterator = upload.getItemIterator(request);
while (iterator.hasNext()) {
fileStream = iterator.next();
if (!fileStream.isFormField())
break;
fileStream = null;
}
if (fileStream == null) {
return new BaseState(false, AppInfo.NOTFOUND_UPLOAD_DATA);
}
String savePath = (String) conf.get("savePath");// /ueditor/jsp/upload/image/{yyyy}{mm}{dd}/{time}{rand:6}
String originFileName = fileStream.getName();//111.png
String suffix = FileType.getSuffixByFilename(originFileName);//.png
originFileName = originFileName.substring(0,
originFileName.length() - suffix.length());//111
savePath = savePath + suffix;///ueditor/jsp/upload/image/{yyyy}{mm}{dd}/{time}{rand:6}.png
long maxSize = ((Long) conf.get("maxSize")).longValue();
if (!validType(suffix, (String[]) conf.get("allowFiles"))) {
return new BaseState(false, AppInfo.NOT_ALLOW_FILE_TYPE);
}
savePath = PathFormat.parse(savePath, originFileName);///ueditor/jsp/upload/image/{yyyy}{mm}{dd}/{time}{rand:6}.png
// String physicalPath = (String) conf.get("rootPath") + savePath;//D:/Program Files/apache-tomcat-7.0.64/wtpwebapps//ueditor/jsp/upload/image/20151116/1447675575987060166.png
/*************zrk修改：改变文件存储路径*************/
String physicalPath = (String) conf.get("physicsPath");
if(physicalPath!=null&&!"".equals(physicalPath))
physicalPath += savePath;
else
physicalPath = conf.get("rootPath") + savePath;
/**************************/
InputStream is = fileStream.openStream();
State storageState = StorageManager.saveFileByInputStream(is,
physicalPath, maxSize);
is.close();
if (storageState.isSuccess()) {
if(storageState.getInfoString("url")==null){
storageState.putInfo("url", PathFormat.format(savePath));
}
storageState.putInfo("type", suffix);
storageState.putInfo("original", originFileName + suffix);
}
return storageState;
} catch (FileUploadException e) {
return new BaseState(false, AppInfo.PARSE_REQUEST_ERROR);
} catch (IOException e) {
}
return new BaseState(false, AppInfo.IO_ERROR);
}
private static boolean validType(String type, String[] allowTypes) {
List<String> list = Arrays.asList(allowTypes);
return list.contains(type);
}
}
改完之后，需要把这个工程右键打成jar包，放到我们test工程lib下，至此修改源码完成。我们的准备工作完成，然后开始写页面和配置ueditor控件参数。
开始设置：1.在我们的要显示是的jsp页面上面（uedit.jsp）导入js和初始化ueditor控件
代码如下：
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>123</title>
<script type="text/javascript" charset="utf-8" src="http://localhost:2022/test/static/utf8-jsp/ueditor.config.js"></script>
<script type="text/javascript" charset="utf-8" src="http://localhost:2022/test/static/utf8-jsp/ueditor.all.min.js"> </script>
<script type="text/javascript" charset="utf-8" src="http://localhost:2022/test/static/utf8-jsp/lang/zh-cn/zh-cn.js"></script>
<style type="text/css">
div{
width:100%;
}
</style>
</head>
<body>
<div>
<textarea name="content" id="content" style='width:80%;height:100%;'></textarea>
</div>
<script type="text/javascript">
//初始化富文本
var ue = UE.getEditor('content',{
toolbars: [
[
'undo', //撤销
'bold', //加粗
'italic', //斜体
'underline', //下划线
'strikethrough', //删除线
'formatmatch', //格式刷
'selectall', //全选
'link', //超链接
'unlink', //取消链接
'fontfamily', //字体
'fontsize', //字号
'insertimage', //多图上传
'help', //帮助
'justifyleft', //居左对齐
'justifyright', //居右对齐
'justifycenter', //居中对齐
'justifyjustify', //两端对齐
'forecolor', //字体颜色
'backcolor', //背景色
'touppercase', //字母大写
'tolowercase', //字母小写
]
],
initialFrameWidth:700,//宽度
initialFrameHeight :320,//高度
});
</script>
</body>
</html> 这时我们访问这个路径：http://localhost:2022/test/uedit/toView.do,可以预览到页面：
2.设置ueditor控件的config.json配置文件（部分代码）:
physicsPath:是这里配置的路径前缀，其实相当于文件服务器的路径，我之前改过UeditorActionEnter类的rootPath，其实这里不需要设置的。
imageUrlPrefix:请求前缀 （这里建议为空，因为浏览器会自带前缀ip和端口的）
imagePathFormat：文件服务器下的子路径，就是说完整的路径是physicsPath+imagePathFormat
代码如下:
/* 上传图片配置项 */
"physicsPath":"E:/apache-tomcat-7.4.44/webapps/",
"imageActionName": "uploadimage", /* 执行上传图片的action名称 */
"imageFieldName": "upfile", /* 提交的图片表单名称 */
"imageMaxSize": 2048000, /* 上传大小限制，单位B */
"imageAllowFiles": [".png", ".jpg", ".jpeg", ".gif", ".bmp"], /* 上传图片格式显示 */
"imageCompressEnable": true, /* 是否压缩图片,默认是true */
"imageCompressBorder": 1600, /* 图片压缩最长边限制 */
"imageInsertAlign": "none", /* 插入的图片浮动方式 */
"imageUrlPrefix": "http://localhost:2022", /* 图片访问路径前缀 */
"imagePathFormat": "/newsImg/{time}{rand:6}", /* 上传保存路径,可以自定义保存路径和文件名格式 */
/* {filename} 会替换成原文件名,配置这项需要注意中文乱码问题 */
/* {rand:6} 会替换成随机数,后面的数字是随机数的位数 */
/* {time} 会替换成时间戳 */
/* {yyyy} 会替换成四位年份 */
/* {yy} 会替换成两位年份 */
/* {mm} 会替换成两位月份 */
/* {dd} 会替换成两位日期 */
/* {hh} 会替换成两位小时 */
/* {ii} 会替换成两位分钟 */
/* {ss} 会替换成两位秒 */
/* 非法字符 \ : * ? " < > | */
/* 具请体看线上文档: fex.baidu.com/ueditor/#use-format_upload_filename */
/* 图片自定义上传地址配置 */3.设置controller.jsp代码，改成我们自己加的那个类的方法。
代码如下:
<%@ page language="java" contentType="text/html; charset=UTF-8"
import="com.baidu.ueditor.upload.UeditorActionEnter"
pageEncoding="UTF-8"%>
<%@ page trimDirectiveWhitespaces="true" %>
<%
request.setCharacterEncoding( "utf-8" );
response.setHeader("Content-Type" , "text/html");
String rootPath = application.getRealPath( "/" );
out.write( new UeditorActionEnter( request, rootPath).exec() );
%>
直接获取图片地址:http://localhost:2022/newsImg/1519962839068090692.png
大功告成。
