JavaWeb解決中文亂碼

一、Get請求，方案有兩種

  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:將從Request做用域中取的參數按iso-8859-1編碼得byte值，再轉成utf-8編碼字符串

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

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

二、POST請求

　　request.setCharacterEncoding("utf-8");
