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。
2.1 首先先创建一个Maven项目,按照图片的目录结构创建包(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分别是三层架构,util是工具类

留言:剩余的部分只需要按照业务需求,将controller,server,dao层的调用关系建立起来便可以访问数据库了。
