对于使用了SSH造成的中文乱码问题，4大解决方法

struts2.xml 中添加 <constant name="struts.i18n.encoding" value="UTF-8"></constant>

jsp页面加入 <%@ page language="java" import="java.util.*" pageEncoding="UTF-8" contentType="text/html; charset=UTF-8"%>

在web.xml 加入针对Spring的拦截器

<!-- 请求与响应的 编码处理 -->

<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>

<filter-mapping>

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

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

</filter-mapping>

4. 修改tomcat的 /conf/server.xml中的<Connector connectionTimeout="20000" port="8080" protocol="HTTP/1.1" redirectPort="8443">为<Connector connectionTimeout="20000" port="8080" protocol="HTTP/1.1" redirectPort="8443" URIEncoding="UTF-8" useBodyEncodingForURI="true" />
