List items = upload.parseRequest(request);为空kindeditor SpringMvc
这个是原kindeditor的原jsp文件这样是完全好用得

所以后面就读不到东西了。
处理方法参见这里：

[解决办法]
FileItemFactory factory = new DiskFileItemFactory();
ServletFileUpload upload = new ServletFileUpload(factory);
upload.setHeaderEncoding("UTF-8");
List items;
try {
items = upload.parseRequest(request);
