1、ueditor官网最新版下载地址: https://ueditor.baidu.com/website/download.html
[1.4.3.3 Jsp 版本] UTF-8版 2016-02-25
2、现象: 集成springboot集成JSP版的ueditor时，往往出现以下问题
配置加载
分析：1、路径不对 2、加载文件读取失败
解决：寻找路径配置文件，ueditor.config.js
//为编辑器实例添加一个路径，这个不能被注释
UEDITOR_HOME_URL: URL
// 服务器统一请求接口路径
, serverUrl: URL + "jsp/controller.jsp"
//工具栏上的所有的功能按钮和下拉框，可以在new编辑器的实例时选择自己需要的重新定义
作用：该配置的目的是让serverUrl访问到controller.jsp页面
<%@ page language="java" contentType="text/html; charset=UTF-8"
import="com.baidu.ueditor.ActionEnter"
pageEncoding="UTF-8"%>
<%@ page trimDirectiveWhitespaces="true" %>
<%
request.setCharacterEncoding( "utf-8" );
response.setHeader("Content-Type" , "text/html");
String rootPath = application.getRealPath( "/" );
out.write( new ActionEnter( request, rootPath ).exec() );
%>
作用：通过controller.jsp页面以及jsp/lib包下面的ueditor-1.1.2.jar来读取并解析config.json文件
image.png
/* 前后端通信相关的配置,注释只允许使用多行方式 */
{
/* 上传图片配置项 */
"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": "", /* 图片访问路径前缀 */
3、解决：只要通过合理的访问路径解析到config.json文件就可以让文件上传功能正常使用
4、搭建springboot开发环境，前端框架使用jasper
可以在 start.spring.io 这个网址创建一个web工程
创建工程
解压导入到idea中，新建工程目录、类，解压ueditor到对应目录结构中如下图所示
工程结构
5、修改pom.xml
<?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"

6、针对读取config.json文件编写对应代码，首先将config.json写成后端路径访问模式
package com.cool.demo.vo;
/**

public class PublicMsg {
public final static String UEDITOR_CONFIG = "{\n" +

"\n" +

" ] \n" +
"\n" +
"}";
7、编写访问路径UeditorController.java，包含返回config.json配置信息，以及文件上传功能
package com.cool.demo.cooldemo;
import com.cool.demo.vo.PublicMsg;
import org.apache.commons.io.FilenameUtils;
import org.apache.commons.io.output.StringBuilderWriter;
import org.springframework.stereotype.Controller;
import org.springframework.util.ResourceUtils;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.multipart.MultipartFile;
import org.springframework.web.multipart.MultipartHttpServletRequest;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;
import java.io.File;
import java.util.HashMap;
import java.util.Map;
/**
* Created by admin on 2019/4/13.
*/
@Controller
public class UeditorController {
/**
* 替换ueditor jsp/controller.jsp文件
* 由于controller.jsp + lib下面的ueditor-1.1.2.jar的作用是读取config.json文件，所以这里直接将config.json文件以字符串的形式返回给了前端
* @param request
* @return
*/
@RequestMapping(value = "/ueditor")
@ResponseBody
public String ueditor(HttpServletRequest request) {
return PublicMsg.UEDITOR_CONFIG;
}
private static final String STORE_PATH = "/image/upload/";
private static final String SERVER_PATH = "http://localhost:8080";
@RequestMapping(value = "/imgUpload")
@ResponseBody
public Map<String, Object> imgUpload(HttpServletRequest request,HttpSession session) {
Map<String, Object> rs = new HashMap<String, Object>();
MultipartHttpServletRequest mReq = null;
MultipartFile file = null;
String fileName = "";
String originalFileName = "";
try {
mReq = (MultipartHttpServletRequest) request;
// 从config.json中取得上传文件的ID "imageFieldName": "upfile", /* 提交的图片表单名称 */
file = mReq.getFile("upfile");
if (!file.isEmpty()) {
// 取得文件的原始文件名称
originalFileName = file.getOriginalFilename();
fileName = originalFileName;
// 设置上传目录
String ext = (FilenameUtils.getExtension(file.getOriginalFilename())).toLowerCase();
String storePath = "";
if ("jpg".equals(ext) || "png".equals(ext) || "jpeg".equals(ext) || "bmp".equals(ext)) {
storePath = STORE_PATH;
} else {
storePath = STORE_PATH;
}
//获取服务器根目录
File path = new File("");
// 编辑上传目录，使其生效
File uploadPath = new File(session.getServletContext().getRealPath("/"),storePath);
//获取上传的图片具体路径
File targetFile = new File(uploadPath, fileName);
//获取父目录
File pfile = new File(uploadPath.getAbsolutePath());
//判断如果目录不存在，先创建
if(!pfile.exists())pfile.mkdirs();
// 文件上传
file.transferTo(targetFile);
rs.put("state", "SUCCESS"); // UEDITOR的规则:不为SUCCESS则显示state的内容
rs.put("url",SERVER_PATH + STORE_PATH + fileName); //能访问到你现在图片的路径
rs.put("title", originalFileName);
rs.put("original", originalFileName);
}
} catch (Exception e) {
e.printStackTrace();
rs.put("state", "文件上传失败!"); //在此处写上错误提示信息，这样当错误的时候就会显示此信息
rs.put("url", "");
rs.put("title", "");
rs.put("original", "");
}
return rs;
}
}
8、修改ueditor.config.js，访问ueditor解析config.json
window.UEDITOR_CONFIG = {
//为编辑器实例添加一个路径，这个不能被注释
UEDITOR_HOME_URL: URL
// 服务器统一请求接口路径
, serverUrl: "/ueditor" // "ueditor" // 这个路径也是可以的
9、ueditor解压后全部放置在webapp/ueditor下，具体参考上面图片；将index.html内容拷贝到index.jsp中，修改以下引用文件的路径src="/ueditor/ueditor.config.js"，并添加以下内容
<head>
<title>完整demo</title>
<meta http-equiv="Content-Type" content="text/html;charset=utf-8"/>
<script type="text/javascript" charset="utf-8" src="/ueditor/ueditor.config.js"></script>
<script type="text/javascript" charset="utf-8" src="/ueditor/ueditor.all.min.js"> </script>
<!--建议手动加在语言，避免在ie下有时因为加载语言失败导致编辑器加载失败-->
<!--这里加载的语言文件会覆盖你在配置项目里添加的语言类型，比如你在配置项目里配置的是英文，这里加载的中文，那最后就是中文-->
<script type="text/javascript" charset="utf-8" src="/ueditor/lang/zh-cn/zh-cn.js"></script>
<style type="text/css">
div{
width:100%;
}
</style>
</head>
<script type="text/javascript">
// 文件上传配置
UE.Editor.prototype._bkGetActionUrl = UE.Editor.prototype.getActionUrl;
UE.Editor.prototype.getActionUrl = function(action) {
if (action == 'uploadimage' || action == 'uploadscrawl' || action == 'uploadimage') {
return 'http://localhost:8080/imgUpload';
//'http://localhost:8080/imgUpload';为方法imgUpload的访问地址
} else {
return this._bkGetActionUrl.call(this, action);
}
}
</script>
10、至此ueditor部分整合完毕，接着配置web项目，在application.properties添加如下内容
spring.mvc.view.prefix=/WEB-INF/views/
spring.mvc.view.suffix=.jsp
11、启动CoolDemoApplication.java，浏览器访问
http://localhost:8080/index
查看整个流程
成功上传界面
正常显示
总结：基本上，jsp/lib目录下的文件可以不用，因为相应的jar包在pom.xml中导入了；其中的ueditor-1.1.2.jar和controller.jsp改为了后端读取
13、附上对应代码，详见gitee，文件上传功能均可用
