解决中文乱码用spring经典编码过滤器 org.springframework.web.filter.CharacterEncodingFilter

使用spring的前提下在web.xml中配置

<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>*.do </url-pattern>

</filter-mapping>

千万要注意他们了的先后顺序，顺序颠倒了就不管用了哦
