Posted 2021-01-26 kuangyefeige

第一步:配置 application.properties

########################################################
###  JSP的支持
########################################################
# 页面默认前缀目录
spring.mvc.view.prefix=/WEB-INF/jsp/
# 响应页面默认后缀
spring.mvc.view.suffix=.jsp
# 自定义属性，可以在Controller中读取
application.hello=Hello Angel From application

第二步：添加相关依赖

第三步：写代码测试

controller：

package com.mt.controller;

import java.util.Date;
import java.util.Map;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class HelloJspController {
    @RequestMapping("/helloJsp")
    public String hello(Map<String, Object> map) {
        map.put("hello", new Date());
        return "hello";
    }
}

View Code

 JSP：

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
    helloJsp
    <hr>
    ${hello}
    
</body>
</html>
