中文乱码

以前一直没有用中文，今天试了一下竟然乱码

解决方法：web.xml

<filter>
  <filter-name>encodingFilter</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>

 

 

并将对应的后缀加入filter-mapping,例如
<filter-mapping>
<filter-name>encodingFilter </filter-name>
<url-pattern>*.action </url-pattern>
</filter-mapping>
