乱码问题，求救啊 谢谢各位大侠啦
servlet的代码为：
package servlet.wl.com;
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;
import User.wl.com.CheckUser;
public class CheckLoginServlet extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
PrintWriter out = response.getWriter();
response.setContentType("text/html");
response.setCharacterEncoding("UTF-8");
String username=request.getParameter("username");
String password=request.getParameter("password");
HttpSession session=request.getSession();
session.setAttribute("user", username);
CheckUser user=new CheckUser();
boolean i=user.check(username, password);
out.print(i);
if (i==true){
request.getRequestDispatcher("loginsuccess.jsp").forward(request, response);
}else{
response.sendRedirect("loginError.jsp");
}
}
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
this.doGet(request, response);
}
}
登录成功显示loginsuccess.jsp，代码为
<%@ page language="java" contentType="text/html; charset=UTF-8" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<base href="<%=basePath%>">

<body>
登录成功！ <br>

</html>
------解决方案--------------------
response.setContentType("text/html");
response.setCharacterEncoding("UTF-8");
替换为：
response.setContentType("text/html;charset=utf-8");
request.setCharacterEncoding("utf-8");
如果form表单提交时method为post,则在doPost里也要加上那两句
试一下吧
