post上传图片获取不到值

问题：执行List items = upload.parseRequest(request); 其中items获取不到值

 1 HttpServletRequest request = ServletActionContext.getRequest();
 2             request.setCharacterEncoding("utf-8");
 3             
 4             boolean isMultipart = ServletFileUpload.isMultipartContent(request);
 5             if (isMultipart) {  
 6                 FileItemFactory factory = new DiskFileItemFactory();  
 7                 ServletFileUpload upload = new ServletFileUpload(factory);  
 8                 upload.setHeaderEncoding("utf-8");
 9                 List items = upload.parseRequest(request); 
10 
11              ｝

解答：

      此情况是struts拦截器产生的。见代码

      在struts.xml中加入配置

     

1 <bean type="org.apache.struts2.dispatcher.multipart.MultiPartRequest"
2         name="myRequestParser" class="com.founder.ngoss.util.RequestParseWrapper"
3         scope="default" optional="true" />
4 <constant name="struts.multipart.parser" value="myRequestParser" />

如果struts是比较旧的版本 constant name = "struts.multipart.handler",这个坑死了

写个自己的拦截器

 1 public class RequestParseWrapper extends JakartaMultiPartRequest {
 2 
 3     @Override
 4     public void parse(HttpServletRequest request, String arg1) throws IOException {
 5         if(!request.getRequestURI().equals("/xx/xx.action")){
 6             super.parse(request, arg1);
 7         }
 8     }
 9 
10 }
就可以完美解决了
