Spring IO platform
Spring IO is a cohesive, versioned platform for building modern applications.
It is a modular, enterprise-grade distribution that delivers a curated set of dependencies while keeping developers in full control of deploying only the parts they need. Spring IO is 100% open source, lean, and modular.
作用
就是指定引入固定的 maven(gradle) parent，默认各个 jar 的版本都经过充分的测试，不会出现冲突。很人性化的设计。
原理
没使用过 gradle，主要谈下 maven 的理解。
就是定义了一堆父类 pom.xml 属性文件，规定了各种 jar 包的版本号。我们使用时只需要直接使用即可，无需指定版本号
Quick Start
新建 maven 项目 spring-io-learn
pom.xml
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.ryo</groupId>
<artifactId>spring-io-learn</artifactId>
<version>1.0-SNAPSHOT</version>
<!--声明-->
<dependencyManagement>
<dependencies>
<dependency>
<groupId>io.spring.platform</groupId>
<artifactId>platform-bom</artifactId>
<version>Athens-SR6</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>
<!--指定需要的jar-->
</project>
为了方便起见，我们测试下 Junit
添加一个不指定版本号的 Junit 依赖，如下：
<dependencies>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<scope>test</scope>
</dependency>
</dependencies>
运行命令
mvn clean install
会发现下载的 Junit 对应的 版本为 4.12
属性
直接点击 pom 可以看到对应的属性如下：
如果你想修改某个版本号，直接指定修改即可。
