一、页面乱码问题的解决
1、jsp页面
在头文件中加入（UTF-8）编码格式：
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>Title</title>
</head>
<body>
<h1>请求失败</h1>
</body>
</html> 2、html页面
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">应用：
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>标题</title>
</head>
<body>
中文正文
</body>
</html>二、request请求的乱码问题
// 设置请求的中文编码格式为（UTF-8)
request.setCharacterEncoding("utf-8");应用：
public class EnglishServlet extends HttpServlet {
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
this.doGet(request, response);
}
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// 设置请求的中文编码格式为（UTF-8)
request.setCharacterEncoding("utf-8");
}
}三、response相应的乱码问题
1、方式一：
// 设置相应的中文编码格式为（UTF-8)
response.setCharacterEncoding("utf-8");
// 将设置的编码格式通知浏览器
response.addHeader("content-type", "text/html;charset=utf-8");2、方式二：
// 合并为一个方法，设置编码格式（UTF-8)
response.setContentType("utf-8");应用：
public class EnglishServlet extends HttpServlet {
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
this.doGet(request, response);
}
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
//方式一：
//设置相应的中文编码格式为（UTF-8)
response.setCharacterEncoding("utf-8");
//将设置的编码格式通知浏览器
response.addHeader("content-type", "text/html;charset=utf-8");
//方式二：
//合并为一个方法，设置编码格式（UTF-8)
response.setContentType("utf-8");
}
