javaweb练习网页自动刷新，为什么网页总是显示乱码，而且不能跳转页面


//案例----网页的自动刷新

package com.pojo.test1;

import javax.servlet.*;
import javax.servlet.http.*;
import javax.servlet.annotation.*;
import java.io.IOException;

@WebServlet(name = "RefreshServlet", urlPatterns = "/refresh")
public class RefreshServlet extends HttpServlet {
    @Override
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

        response.setContentType("text/html:charset=UTF-8");     //设置响应编码为utf-8
        response.setHeader("refresh","3:url='Home.html'"); //在响应头中设置3秒后跳转
        response.getWriter().print("3秒后自动刷新");        //将这段话输出到网页
    }

    @Override
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

    }
}

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
<h2>来到我的网站！············</h2>
</body>
</html>

代码换成如下
1.乱码 未设置 指定对服务器响应进行重新编码的编码 response.setCharacterEncoding("UTF-8");
2.未刷新跳转 只需要你路径就好 不用嵌套 没有设置响应状态 response.setStatus(302);


@Override
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        response.setCharacterEncoding("UTF-8");
        response.setContentType("text/html:charset=UTF-8");     //设置响应编码为utf-8
        response.getWriter().write("3秒后自动刷新");        //将这段话输出到网页
        response.setStatus(302); // 设置响应状态
        response.setHeader("refresh", "3;url=/Home.html");

    }

Home.html 这个页面存在么?
应该是 Home.jsp吧 路径是不是不对
