SpringMVC中文乱码问题–＞使用MVC自带过滤器解决

<!--    过滤器-->
    <filter>
        <filter-name>encoding</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>
    </filter>
    <filter-mapping>
        <filter-name>encoding</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

注意：

filter-mapping中url-pattern参数/时无法过滤jsp页面，必须使用/*作为参数；
