解决POST、GET请求中文乱码问题

1.post请求

    <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>

2.get请求

（1）修改tomcat配置文件添加编码与工程编码一致，如下：

    <ConnectorURIEncoding="utf-8" connectionTimeout="20000" port="8080" protocol="HTTP/1.1" redirectPort="8443"/>

（2）对参数进行重新编码：

String userName = new    String(request.getParamter("userName").getBytes("ISO8859-1"),"utf-8")
