Spring Multipart上传

1：在application.xml中初始化CommonsMultipartResolver 两个参数

 <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">  
        <!-- 文件大小-->
        <property name="maxUploadSize" value="2000000" />  
         <!-- 默认编码 -->
        <property name="defaultEncoding" value="UTF-8" />  
    </bean>

2:获取上传文件

//转换请求
MultipartHttpServletRequest multipartRequest = (MultipartHttpServletRequest) request;  
//获得文件		 
CommonsMultipartFile cFile = (CommonsMultipartFile) multipartRequest.getFile("file");

3:jsp 页面 form 添加上传属性
enctype="multipart/form-data"
metho 指定为post 提交
