Spring MVC过滤器-字符集过滤器（CharacterEncodingFilter）中文乱码问题

springMvc 中文乱码问题。 

 示例：

[java] view
plain copy

       <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>  

        以上代码放置在web.xml中，相当于servlet中的：

[java] view
plain copy

request.setCharacterEncoding("UTF-8");  

response.setCharacterEncoding("UTF-8");
