解决post请求乱码问题:

在web.xml中加入:

    <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>

解决post请求乱码问题:

get请求中文参数出现乱码解决方法有两个:

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.另外一种方法对参数进行重新编码:

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

ISO8859-1是tomcat默认编码,需要将tomcat编码后的内容按utf-8编码
