一、技術背景

在不同的環境，要打不同版本的API包，開發測試環境打SNAPSHOT，線上要打RELEASE包，但是每次都要上線之前都要改代碼，很麻煩，所以用更通用的配置來解決這個問題。

二、實現

pom文件配置

    <groupId>com.yx</groupId>
	<artifactId>yx-test-api</artifactId>
	<version>${version.final}</version>
	<name>test-api</name>

	<properties>
        <java.version>1.8</java.version>
		<version.current>1.0.0</version.current>
		<project.version>1.0.0</project.version>
	</properties>
    
    <distributionManagement>
		<repository>
			<id>nexus</id>

		<snapshotRepository>
			<id>nexus</id>
			<name>snapshots</name>
			<url>http:</url>
			<uniqueVersion>false</uniqueVersion>
		</snapshotRepository>
	</distributionManagement>
	<repositories>
		<repository>
			<id>Nexus</id>
			<name>Nexus Public Repository</name>
			<url>http:</url>
		</repository>
	</repositories>

	<build>

	</build>

        <profiles>
		<profile>
			<id>dev</id>

				<active>dev</active>

				<active>test</active>
				<version.final>${version.current}-RELEASE</version.final>
			</properties>
			<activation>
				<!-- 默認環境 -->
				<activeByDefault>true</activeByDefault>
			</activation>
		</profile>
		<profile>
			<id>prod</id>
			<properties>
				<active>prod</active>
				<version.final>${project.version}-RELEASE</version.final>
			</properties>
		</profile>
	</profiles>

其中<active> 標籤，是根據application.properties的配置
