JavaWeb解决中文乱码

1、Get请求，方案有两种

  A:修改Tomcat配置文件 server.xml   URIEncoding="UTF-8"

     如：<Connector port="8081" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8445" URIEncoding="UTF-8" />

 B:将从Request作用域中取的参数按iso-8859-1编码得byte值，再转成utf-8编码字符串

　　如： String userName= request.getParameter("userName");

            userName = new String(userName.getBytes("iso-8859-1"),"utf-8");

2、POST请求

　　request.setCharacterEncoding("utf-8");
