springboot依赖管理

定义了大量第三方的版本号，在使用以来的时候，就不需要自己指定版本号了。
官方仲裁的版本号不一定合适，就需要自定义版本号。
如何自定义依赖的版本号：
version标签：手动指定
properties标签:指定依赖的版本号
一、spring-boot-starter-parent

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>3.4.5</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>

spring-boot-starter-parent进入这个依赖。（Ctrl+鼠标左键）

可以发现，它继承了spring-boot-dependencies这个依赖，里面有许多版本控制管理（版本仲裁）。

    <yasson.version>3.0.4</yasson.version>
  </properties>

因此，我们就不需要定义myqsql的版本。

但是，并不是官方仲裁的版本就一定合适。如果不想使用官方仲裁的版本，就自定义版本号。
还可以在properties标签下制定版本号：

二、spring-boot-starter-web

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

是一组可用的依赖，集成了许多依赖，如json、tomcat、springmvc相关的依赖。
所以，只要导入web启动器，就可以使用这些依赖。
在浏览器中以json格式显示数据：
原理：

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

进入这个依赖

发现图片中有依赖：

<dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-json</artifactId>
      <version>3.4.5</version>
      <scope>compile</scope>
    </dependency>

而这个依赖里面又有很多与json有关的依赖，所以才能出现浏览器中的效果。
三、启动器分类
1.官方的启动器
spring-boot-start-xxx
2.第三方启动器
xxx-spring-boot-start
需要写明版本号
