pom.xml

<!-- 文件上传 -->   <dependency>    <groupId>commons-fileupload</groupId>    <artifactId>commons-fileupload</artifactId>    <version>1.3</version>   </dependency>   <dependency>    <groupId>commons-io</groupId>    <artifactId>commons-io</artifactId>    <version>2.4</version>   </dependency>

web.xml 解决上传后中文文件名乱码问题

<!-- 解决提交时中文乱码问题 start -->  <filter>    <filter-name>Set Character Encoding</filter-name>    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>    <init-param>     <param-name>encoding</param-name>     <param-value>UTF-8</param-value>    </init-param>  </filter>  <filter-mapping>   <filter-name>Set Character Encoding</filter-name>   <url-pattern>/*</url-pattern>  </filter-mapping>  <!-- 解决提交时中文乱码问题 end -->

servlet-context.xml中添加对上传的支持

<!-- 支持文件上传 -->  <beans:bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">  </beans:bean>

Java的controller文件
