java - Spring/Jboss - 当前请求不是多部分请求

Question

我正在尝试创建一个休息网络服务，用户可以在其中发送带有一些参数的 httpPostrequest。这是我的代码

@RequestMapping(value="/SubmitDetails")
@ResponseBody
public String saveCase(@RequestParam("details") String details){
       //Do SomeWork
     return "some response";
}

但是当我从我的浏览器访问这个 URL 时它抛出:

exception

org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.springframework.web.multipart.MultipartException: Current request is not a multipart request
    org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:982)

    javax.servlet.http.HttpServlet.service(HttpServlet.java:803)

此代码在 Tomcat 上运行良好，但在 JBOSS 4.2 上运行不佳

对于 Post 请求，我使用来自 Android 的 Volly:

void HttpStringRequest(final int request , String url, final Map<String,String> keyVal){

    StringRequest stringRequest = new StringRequest(request, url, new Response.Listener<String>() {

        @Override
        public void onResponse(String response) {
            Helper.getmHelper().v(this.getClass().getName()+":RESPONSE:",response);

            hideProgress();
        }
    }, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {
            Helper.getmHelper().v(this.getClass().getName()+":ERROR:","Error");

            hideProgress();
        }
    }
    ) {
        @Override
        protected Map<String, String> getParams() {
            Iterator<Map.Entry<String, String>> it = keyVal.entrySet().iterator();
            while (it.hasNext()) {
                Map.Entry<String, String> pairs = (Map.Entry<String, String>) it.next();
                Helper.getmHelper().v(pairs.getKey(), pairs.getValue());
            }
            return keyVal;
        }

       @Override
        public Map<String, String> getHeaders() throws AuthFailureError {
            HashMap<String, String> headers = new HashMap<String, String>();
            headers.put("Content-Type", "text/plain; charset=utf-8");
            return headers;
        }


    };
    stringRequest.setRetryPolicy(new DefaultRetryPolicy(60*1000,0,DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));
    queue.add(stringRequest);
}

检查Spring-Servlet.xml中是否添加了CommonsMultipartResolver

<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"/>

然后，将 enctype 添加到表单中的 multipart/form-data 中:

<form id="fileupload" method="post" enctype="multipart/form-data">

最后在Controller中，Request > MultipartHttpServletRequest:

@RequestMapping(value="/SubmitDetails"  method = RequestMethod.POST)
public String saveCase(MultipartHttpServletRequest request) {}
