UEditor百度富文本后端上传文件接口
直接上代码
接口：

@RequestMapping("/UEditorConfig")public String list(HttpServletRequest request, HttpServletResponse response) throws IOException {String config = environment.getProperty("ueditor.config.dir");String action = request.getParameter("action");String noCache = request.getParameter("noCache");if ("config".equals(action))return (new ActionEnter(request, config, "")).exec();else{String encode = request.getParameter("encode");MultipartHttpServletRequest multipartRequest = (MultipartHttpServletRequest) request;MultipartFile file = multipartRequest.getFile("upfile");String fileName = file.getOriginalFilename();String contentType = file.getContentType();long fileSize = file.getSize();String filePath = FileUploadUtils.upload(file);JSONObject jsonObject=new JSONObject();jsonObject.put("state","SUCCESS");jsonObject.put("original","myz.png");jsonObject.put("size", String.valueOf(fileSize));jsonObject.put("title",fileName);jsonObject.put("type",contentType);jsonObject.put("url",filePath);return jsonObject.toString();}}

其实就两种情况

一、读取配置文件

前端加载富文本时会请求一次富文本接口，而且上传文件时也是用的这个接口

if ("config".equals(action))return (new ActionEnter(request, config, "")).exec();

注意：ActionEnter是引入百度富文本的包
import com.baidu.ueditor.ActionEnter;

        <dependency><groupId>com.gitee.qdbp.thirdparty</groupId><artifactId>ueditor</artifactId><version>1.4.3.3</version></dependency>

如果接口返回如下内容，说明你成功了，前端应该可以上传文件了(不会报后端配置错误)

二、上传文件

本质上就是返回一个json，自己构建就好了

else{String encode = request.getParameter("encode");MultipartHttpServletRequest multipartRequest = (MultipartHttpServletRequest) request;MultipartFile file = multipartRequest.getFile("upfile");String fileName = file.getOriginalFilename();String contentType = file.getContentType();long fileSize = file.getSize();String filePath = FileUploadUtils.upload(file);JSONObject jsonObject=new JSONObject();jsonObject.put("state","SUCCESS");jsonObject.put("original","myz.png");jsonObject.put("size", String.valueOf(fileSize));jsonObject.put("title",fileName);jsonObject.put("type",contentType);jsonObject.put("url",filePath);return jsonObject.toString();}

注意这里
HttpServletRequest里面的file要从 MultipartHttpServletRequest 拿出来

MultipartHttpServletRequest multipartRequest = (MultipartHttpServletRequest) request;
MultipartFile file = multipartRequest.getFile("upfile");

FileUploadUtils.upload是我自己框架的上传文件方法，如果你的框架没有，可能需要自己写一个

 String filePath = FileUploadUtils.upload(file);

搞定


ps:其实读取配置文件的接口本质上也是返回一个json，如果你愿意，也可以自己构建这个json，不引入百度的maven包
