org/apache/commons/fileupload/FileItemFactory异常处理

这个问题产生原因：

  MultipartResolver resolver = new CommonsMultipartResolver(request.getSession().getServletContext());
  MultipartHttpServletRequest multipartRequest = resolver.resolveMultipart(request);

用了这么个东西：

但是却没依赖war包，导致在上面代码第一行直接异常抛出，抛出也看不出啥，点开ex 异常 查看DetailMessage 

发现有如下：

org/apache/commons/fileupload/FileItemFactory

解决办法添加依赖：

        <dependency>
            <groupId>commons-fileupload</groupId>
            <artifactId>commons-fileupload</artifactId>
           <version>1.2.1</version>
        </dependency>
