servlet中解决中文乱码的方法
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");
}
