spring mvc配置上传文件的大小

在**-servlet.xml中增加以下配置

 

 <!-- 上传文件大小最大20M MultipartResolver for parsing file uploads, implementation for Commons FileUpload -->    <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">        <!-- set the upload file's size to 1MB ????-->        <property name="maxUploadSize">               <value>20971520</value>          </property>    </bean>

默认的为10M=10485760

20M对应的20971520
