MultipartHttpServletRequest

MultipartHttpServletRequest

1. Form method="post" enctype="multipart/form-data"

2. File type input 

3.   定義multipartResolver
        class="org.springframework.web.multipart.commons.CommonsMultipartResolver" 在spring configure file中。

接下來就能夠直接將request轉爲MultipartHttpServletRequest啦
