struts2中文传值乱码

首先数据库，jsp页面，jsp文件，tomcat的编码都统一为UTF-8。

其次在jsp页面上增加

<% request.setCharacterEncoding("UTF-8"); %>

最后在web.xml里添加过滤器

<!-- encoding -->
    <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>
