本篇文章主要介紹了springmvc利用jquery.form插件異步上傳文件示例，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下。

需要的下載文件：

jQuery.form.js

jquery.js

commons-fileupload.jar

commons-io.jar

示例圖片

pom.xml

<!-- 文件上傳 --> 
  <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 解決上傳后中文文件名亂碼問(wèn)題

<!-- 解決提交時(shí)中文亂碼問(wèn)題 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> 
 <!-- 解決提交時(shí)中文亂碼問(wèn)題 end -->

servlet-context.xml中添加對(duì)上傳的支持

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