SpringMVC乱码过滤器配置

    <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>

上诉方式只对post请求有效

如需要对get 全局请求有效，一种方式修改Tomcat server.xml文件

<Connector port="8080" maxHttpHeaderSize="8192" 
              maxThreads="150" minSpareThreads="25" maxSpareThreads="75" 
              enableLookups="false" redirectPort="8443" acceptCount="100" 
              connectionTimeout="20000" disableUploadTimeout="true" uRIEncoding="UTF-8"/>

另一种自定义利用包装类来过滤 或者动态代理

贴一下Warper方式
