java get方法提交中文乱码问题

tomcat 下的conf/server.xml

<Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443"/>

换成

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

 

1、在JS里对中文参数进行两次转码 

var login_name = document.getElementById("loginname").value;  
login_name = encodeURI(login_name);  
login_name = encodeURI(login_name);  
2、在服务器端对参数进行解码 

String loginName = ParamUtil.getString(request, "login_name");  
loginName = java.net.URLDecoder.decode(loginName,"UTF-8");
