get请求乱码

1、get请求不管用什么编码都是乱码，

2、由于http请求最先到达的是容器，所以先要检查容器的unrencodeing

<Connector port="80" protocol="HTTP/1.1"
           connectionTimeout="20000"
           redirectPort="18443" URIEncoding="UTF-8" />
3、如果这个正确，在检查web.xml里边的配置是否正确

<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>
    </filter>
    <filter-mapping>
      <filter-name>CharacterEncodingFilter</filter-name>
      <url-pattern>/*</url-pattern>
    </filter-mapping>
