1、設置eclips , window->Preferences->web->JSP Files中的Encoding選項為UTF-8

2、修改jsp文件頭部為UTF-8

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>

3、設置servlet中request對象編碼

public class RegisterServlet extends HttpServlet{      public void doGet(HttpServletRequest request,HttpServletResponse response)                  throws ServletException,IOException{                   request.setCharacterEncoding("UTF-8");                   ........       }  }

4、如果還是亂碼，設置tomat中的配置文件

Tomcat的server.xml文檔中的 <Connector> 配置中增加

useBodyEncodingForURI="true" IEncoding="utf-8" URIEncoding="utf-8"
