List items = upload.parseRequest(request);替空kindeditor SpringMvc

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

然后我想要转换成SpringMvc得形式我就创建了个controller代码一切正常我DEBUG了一下发现List items = upload.parseRequest(request);为空有谁遇到过这个问题帮忙解决一下

第一次发帖格式上也许不太符合大众得观看习惯 还请大家多多指教

请问这个问题解决没lz 我也遇到这个问题啊
[解决办法]
这个问题，一般是因为InputStream已经被struts2给预先读取过了（因为它要帮你检查是否有VO值对象需要处理之类的）

所以后面就读不到东西了。


处理方法参见这里：

[解决办法]

Java code

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