SpringMVC系列之文件上传【springmvc整合commons-fileupload实现文件上传功能】

一、Maven依赖

• commons-fileupload

<dependency>  
	<groupId>commons-fileupload</groupId>  
	<artifactId>commons-fileupload</artifactId>  
	<version>1.3.3</version> 
</dependency>

二、需要配置的Bean对象

• multipartResolver

<!-- id的值必须是multipartResolver --> 
<bean id="multipartResolver"  class="org.springframework.web.multipart.commons.CommonsMultipartResolver">  
	<!-- 允许上传的文件大小:2MB 【1024*1024*2】-->
