SpringBoot整合jsp

1.建立一个maven项目，必须选择war类型，不然无法访问页面

2.在pom.xml添加依赖

<parent>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-parent</artifactId>
		<version>2.0.0.RELEASE</version>
	</parent>
	<dependencies>
		<!-- SpringBoot web 核心组件 -->
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-web</artifactId>
		</dependency>
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-tomcat</artifactId>
		</dependency>
	<!-- SpringBoot 外部tomcat支持 -->	
	<dependency>
			<groupId>org.apache.tomcat.embed</groupId>
			<artifactId>tomcat-embed-jasper</artifactId>
		</dependency>
	</dependencies>
添加依赖后会有一个报错，是项目没有web.xml的缘故

4.在src/main/resources中建立application.properties文件，SpringBoot默认读取，不能修改

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

5.新建一个开发控制器类

package com.itjsp.controller;

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

@Controller

public class jspcontroller {
	@RequestMapping("/jspindex")
	public String jspindex() {
		return "jspindex";
	}

}

6.在src/mian/webapp/WEB-INF下建立一个jsp文件,改编码为UTF-8

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
</head>
<body>
<h1>菜鸟</h1>
</body>
</html>

7.建立启动类

package com.itjsp;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class Jspstart {
	public static void main(String[] args) {
		SpringApplication.run(Jspstart.class, args);
	}

}

8.运行 SpringBoot整合jsp

注意
1.webapp不能和main同级
2.启动类包要放在最外层，要包含所有子包，springboot才会自动加载启动类所在包下及其子包下的所有组件。.
