dependencyManagement

1. 定義依賴包版本管理
2. 繼承不會引入依賴
3. 子類dependencies引入即可才會載入依賴

<properties>
	<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
	<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
	<spring-cloud.version>Dalston.SR4</spring-cloud.version>
	<java.version>1.8</java.version>
	<swagger.version>2.8.0</swagger.version>
	<druid.version>1.1.9</druid.version>
	<jackson.version>2.9.8</jackson.version>
</properties>
<dependencyManagement>
	<dependencies>
		<dependency>
			<groupId>org.springframework.cloud</groupId>
			<artifactId>spring-cloud-dependencies</artifactId>
			<version>${spring-cloud.version}</version>
			<type>pom</type>
			<scope>import</scope>
		</dependency>
	</dependencies>
</dependencyManagement>
 

dependencies

1. 定義服務依賴包
2. 服務依賴包未定義版本號，會向上尋找dependencyManagement獲取版本號

<dependencies>
	<dependency>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-aop</artifactId>
		<exclusions>
			<exclusion>
				<groupId>org.springframework.boot</groupId>
				<artifactId>spring-boot-starter-logging</artifactId>
			</exclusion>
		</exclusions>
	</dependency>
</dependencies>
