springcloud版本和springboot的版本选择
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-dependencies</artifactId>
<version>2.2.4.RELEASE</version>
<type>pom</type>
<scope>import</scope>
</dependency>
<!--spring cloud Hoxton.SR1-->
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-dependencies</artifactId>
<version>Hoxton.SR1</version>
<type>pom</type>
<scope>import</scope>
</dependency>
父项目使用dependencyManagement管理依赖的导入
Maven中的dependencyManagement元素提供了一种管理依赖版本号的方式。
在dependencyManagement元素中声明所依赖的jar包的版本号等信息,那么所有子项目再次引入此依赖jar包时则无需显式的列出版本号。Maven会沿着父子层级向上寻找拥有dependencyManagement 元素的项目,然后使用它指定的版本号,通俗的来讲,子项目会寻找父项目中同一组织的版本号,这样的话子版本就不用写版本号,便于版本管理.
常用的父项目的pom.xml配置
