SpringBoot(2)之父工程与场景启动器

父工程

这里的 Pom 文件使用的是前一篇入门程序搭建中使用的 Pom 文件。

首先,我们引入了一个父工程:

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.1.3.RELEASE</version>
    <relativePath/>
</parent>

而这个父工程本身还有一个父工程:

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-dependencies</artifactId>
    <version>2.1.3.RELEASE</version>
    <relativePath>../../spring-boot-dependencies</relativePath>
</parent>

这个父工程管理了 SpringBoot 应用中的所有依赖版本,它可以称为 SpringBoot 的版本管理中心,所以以后我们导入它管理的依赖是不需要声明版本的。

场景启动器

我们还引入如下依赖:

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

该依赖帮我们导入了 Web 模块正常运行所有依赖的组件。

在使用 SpringBoot 的过程中,还有很多 artifactIdspring-boot-starter 开头的依赖,这种依赖就被成为场景启动器。

SpringBoot 将所有功能场景都抽取出来,做成一个个 starter (场景启动器),只需要在项目中引入这些 starter 相关场景的所有依赖都会导入进来,要使用什么功能就导入什么场景启动器。
