web.xml/servlet过滤器之CharacterEncodingFilter

配置CharacterEncodingFilter过滤器，你能够强制将请求或者相应设置成utf-8，规避乱码的风险。

<filter>

 <filter-name>SetCharacterEncoding</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>SetCharacterEncoding</filter-name>

 <url-pattern>/*</url-pattern>

</filter-mapping>
