在引入父pom之前咱们先来回顾下dependencyManagement与使用他的原因
什么是dependencyManagement:他可以统一管理项目的版本号,确保应用的各个子项目的依赖和版本一致,当需要变更版本号的时候只需要在父类容器里更新,不需要任何一个子项目的修改;如果某个子项目需要另外一个特殊的版本号时,只需要在自己的模块dependencies中声明一个版本号即可。子类就会使用子类声明的版本号,不继承于父类版本号。
为什么用dependencyManagement:首先在springCloudAlibaba的项目中对于版本的依赖要求很严格,所有需要统一来声明管理每隔依赖的版本号。版本之间的关系参考SpringCloudAlibaba实战教程系列
<dependencyManagement> <dependencies> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-dependencies</artifactId> <version>Greenwich.SR3</version> <type>pom</type> <scope>import</scope> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-dependencies</artifactId> <version>2.1.8.RELEASE</version> <type>pom</type> <scope>import</scope> </dependency> <dependency> <groupId>com.alibaba.cloud</groupId> <artifactId>spring-cloud-alibaba-dependencies</artifactId> <version>2.1.0.RELEASE</version> <type>pom</type> <scope>import</scope> </dependency> </dependencies> </dependencyManagement>
在引入上面的版本声明之后在父pom中引入下面几个将要使用的依赖
<dependencies> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <optional>true</optional> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> </dependencies>
完整的pom如下:
<?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.niu.cloud</groupId> <artifactId>cloud-alibaba</artifactId> <packaging>pom</packaging> <version>1.0-SNAPSHOT</version> <modules> <module>nacos-provider</module> <module>nacos-comsumer</module> </modules> <dependencyManagement> <dependencies> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-dependencies</artifactId> <version>Greenwich.SR3</version> <type>pom</type> <scope>import</scope> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-dependencies</artifactId> <version>2.1.8.RELEASE</version> <type>pom</type> <scope>import</scope> </dependency> <dependency> <groupId>com.alibaba.cloud</groupId> <artifactId>spring-cloud-alibaba-dependencies</artifactId> <version>2.1.0.RELEASE</version> <type>pom</type> <scope>import</scope> </dependency> </dependencies> </dependencyManagement> <dependencies> <!--lombok--> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <optional>true</optional> </dependency> <!--spring web--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> </dependencies> <repositories> <!--指定阿里云镜像库下载依赖--> <repository> <id>central</id> <name>aliyunmaven</name> <url>http://maven.aliyun.com/nexus/content/groups/public/</url> </repository> </repositories> </project>
