1、设置eclips , window->Preferences->web->JSP Files中的Encoding选项为UTF-8

2、修改jsp文件头部为UTF-8

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

3、设置servlet中request对象编码

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

4、如果还是乱码，设置tomat中的配置文件

Tomcat的server.xml文档中的 <Connector> 配置中增加

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