SpringBoot框架搭建

1.简介

SpringBoot框架最大的有点在于快速开发，快速开发的原理就是SpringBoot中的三大主要配置：

起步依赖，引导类，属性配置文件（两类三种，第一类是application.yaml和application.yml类的配置文件，第二类是application.properties)
1.起步依赖：将一个框架所必须的依赖jar包和环境集成，直接引入起步依赖便完成了jar包的引入问题。
2.引导类：可直接启动项目
3.属性配置文件：可以将数据源，端口。。等信息添加进去，具体的配置方式需要按照要求引入。

2.搭建步骤

2.1 首先先创建一个Maven项目，按照目录结构创建包（Application.java是引导类，引导类必须放在当前项目的根目录下，否则不会出现spring的图标，项目无法启动）controller/service/dao（mapper）分别是三层架构，util是工具类

2.2在pom.xml中添加起步依赖

2.3属性配置文件application.properties

    #DB Configuration:

    spring.datasource.driverClassName=com.mysql.cj.jdbc.Driver

    spring.datasource.url=jdbc:mysql://localhost:3306/space?serverTimezone=UTC

    spring.datasource.username=root

    spring.datasource.password=123456


    #JPA Configuration:

    spring.jpa.database=MySQL

    spring.jpa.show-sql=true

    spring.jpa.generate-ddl=true

    spring.jpa.hibernate.ddl-auto=update

    spring.jpa.hibernate.naming_strategy=org.hibernate.cfg.ImprovedNamingStrategy

    spring.freemarker.checkTemplateLocation=false

    spring.thymeleaf.cache=false

2.4创建引导类

    @SpringBootApplication
    public class Application {
    	public static void main(String[] args) {
        	//启动springboot实例化spring容器调用内置的tomcat
    		SpringApplication.run(Application.class, args);
    	}
    }

项目到这里就创建完成了，接下来是启动springboot，当出现下图时则表明启动成功

接下来完善各个层的代码，就完成了springboot的搭建。
