1、自动装配

在之前的文章中已经专门写过这里不做赘述。
1.2、pom.xml
1.2.1、版本管理
在学习完maven项目后我们学习框架时首先阅读的就是pom.xml文件这里是管理自己该项目中所用到的jar包。
学习SpringBoot时也是一样在创建好一个项目后我们首先先浏览一下pom.xml。
parentgroupIdorg.springframework.boot/groupIdartifactIdspring-boot-starter-parent/artifactIdversion2.7.3/versionrelativePath/ !-- lookup parent from repository --/parent打开这个文件后我们首先就能看到上面这串代码这个和我们之前学习的不太一样仔细阅读后可以发现这时导入Springboot父依赖的代码。
什么是父依赖
当我们按住ctrl鼠标点击这个依赖可以发现我们又进入了一个pom文件在这里我们又能看到一个父依赖。
parentgroupIdorg.springframework.boot/groupIdartifactIdspring-boot-dependencies/artifactIdversion2.7.3/version/parent再次点击进入便能发现这里管理着大量的版本信息

springBoot的启动器spring Boot的启动场景。
dependencygroupIdorg.springframework.boot/groupIdartifactIdspring-boot-starter/artifactId/dependency比如spring-boot-starter-web它会自动导入web项目所需要的所有依赖。
dependencygroupIdorg.springframework.boot/groupIdartifactIdspring-boot-starter-web/artifactId/dependencyspring boot会将所有的功能场景都编程一个个的启动器如果我们要使用什么功能就只需要找到对应的启动器就行了。
