今天碰到一个问题，就是GET请求接收到的数据中中文总是乱码

web.xml配置

    <!--过滤字符集-->
    <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>
        <init-param>
            <param-name>forceEncoding</param-name>
            <param-value>true</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>encoding</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

百度了一下了解到这个是针对POST的，如果要针对GET做处理需要修改tomcat的配置文件

server.xml

 <Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443"
               URIEncoding="UTF-8" />

在Connector后面加入 URIEncoding="UTF-8"，这样GET请求就不会发生中文乱码的现象了
