spring+commons-fileupload上传文件大小限制异常捕获

[WYH_D_VOID]

配置文件中如下配置

 <!-- SpringMVC上传文件时，需要配置MultipartResolver处理器 -->  
    <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">  
        <property name="defaultEncoding" value="UTF-8"/>  
        <!-- 指定所上传文件的总大小不能超过200KB。注意maxUploadSize属性的限制不是针对单个文件，而是所有文件的容量之和 -->  
        <property name="maxUploadSize" value="2000"/>
        <!--resolveLazily属性启用是为了推迟文件解析，以便在UploadController 中捕获文件大小异常-->  
        <property name="resolveLazily" value="true"/> 
    </bean>  

在Controller中，采用@ExceptionHandler处理异常

/**
     * 异常处理
     * @param ex
     * @param request
     * @Description:
     */
    @ExceptionHandler(Exception.class)
    public void handleException(Exception ex,HttpServletRequest request,HttpServletResponse response){
        StringBuffer sb = new StringBuffer();
        sb.append("<script language='javascript'>history.go(-1);alert('");
        if (ex instanceof org.springframework.web.multipart.MaxUploadSizeExceededException){
            sb.append("文件大小不应大于"+((MaxUploadSizeExceededException)ex).getMaxUploadSize()/1000+"kb");
         } else{
             sb.append("上传异常！");
        }
        sb.append("！');</script>");
        try {
            System.out.println(sb.toString());
            response.setContentType("text/html; charset=utf-8");  
            response.getWriter().println(sb.toString());
            response.getWriter().flush();
        } catch (IOException e) {
            e.printStackTrace();
        }
        return;
    }

上传文件大小限制为200kb，上传一个1-3MB大小的文件，会正常执行，在页面上弹出提示

但是如果上传一个比较大的文件，比如40MB的，就会出现
ReadResponse() failed: The server did not return a response for this request. Server returned 0 bytes.
！

顺便一说，如果在异常捕获的方法中加入

try {
                Thread.sleep(1*1000);
            } catch (InterruptedException e1) {
                e1.printStackTrace();
            }

就不会出现 ReadResponse() failed: The server did not return a response for this request. Server returned 0 bytes.！ 求解！

[其所以然]

请问怎么解决的？
