spring mvc3 提交表单乱码问题解决方法

在web.xml中添加几行代码即可：

<filter>
  <filter-name>characterEncodingFilter</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>
  <init-param>
   <param-name>forceEncoding</param-name>
   <param-value>true</param-value>
  </init-param>
 </filter>
 
 <filter-mapping>
  <filter-name>characterEncodingFilter</filter-name>
  <url-pattern>/*</url-pattern>
 </filter-mapping>

 

在上面的代码中：

 <filter-mapping>
  <filter-name>characterEncodingFilter</filter-name>
  <url-pattern>/*</url-pattern>
 </filter-mapping>的

  <url-pattern>/*</url-pattern>

中间内容必须写成/*,如果只写/还是乱码，解决不了问题。
