springboot和springframework版本对应关系哪里看

先介绍一下什么是spring boot.

Spring Boot是为了简化Spring应用的创建、运行、调试、部署等而出现的，使用它可以做到专注于Spring应用的开发，而无需过多关注XML的配置。

简单来说，它提供了一堆依赖打包，并已经按照使用习惯解决了依赖问题---习惯大于约定。

Spring Boot默认使用tomcat作为服务器，使用logback提供日志记录。

一、加入maven依赖

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

  <packaging>war</packaging>
   <!--对spring boot父项目的依赖-->

        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>

    </parent>

  <dependencies>
  <!-- https://mvnrepository.com/artifact/org.apache.tomcat.embed/tomcat-embed-core  启动项目需要调用改引用 -->

      <!-- 
            devtools可以实现页面热部署（即页面修改后会立即生效，这个可以直接在application.properties文件中配置spring.thymeleaf.cache=false来实现），
            实现类文件热部署（类文件修改后不会立即生效），实现对属性文件的热部署。
            即devtools会监听classpath下的文件变动，并且会立即重启应用（发生在保存时机），注意：因为其采用的虚拟机机制，该项重启是很快的

       <dependency>
