#SPringboot #对JSP的支持

本文详细介绍SpringBoot Web应用的构建过程，包括项目结构、Maven配置、Controller编写及JSP视图展示。通过实例演示如何配置前端控制器，实现动态时间显示。

项目结构图
在这里插入图片描述
SpringBoot的启动项，带有注解@SpringBootApplication的类所在的包要包括其他类的所在的包
下面是SpringBoot的jar包

配置Controller的前端控制器在application.properties中配置

spring.mvc.view.prefix=/WEB-INF/jsp/
spring.mvc.view.suffix=.jsp

HelloController

package com.howjava.springboot.web;

import java.text.DateFormat;
import java.util.Date;

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

/**
 * @verion:1.0
 * @description:
 */
@Controller
public class HelloController {
	@RequestMapping("/hello")
	public String hello(Model m){
		m.addAttribute("now",DateFormat.getDateTimeInstance().format(new Date()));
		return "date";
	}
}

JSP文件

<%@ page contentType="text/html; charset=utf-8" pageEncoding="utf-8" isELIgnored="false"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>1</title>
</head>
<body>
现在的时间是：${now }
</body>
</html>
