springBoot项目中，如何根据不同的环境，打包不同的配置文件（maven）

版权声明：转发请注明，谢谢配合 https://blog.csdn.net/qq_31289187/article/details/85116371

1、创建springboot项目，然后创建不同的resource

2、application.properties加上一个标志，方便测试

3、在pom.xml中定义全局配置信息

<?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>
	<parent>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-parent</artifactId>
		<version>2.1.1.RELEASE</version>
		<relativePath/> <!-- lookup parent from repository -->
	</parent>
	<groupId>com.cn.dl</groupId>
	<artifactId>springboot-maven-package-demo</artifactId>
	<version>0.0.1-SNAPSHOT</version>
	<name>springboot-maven-package-demo</name>
	<description>Demo project for Spring Boot</description>

	<properties>
		<java.version>1.8</java.version>
	</properties>


	<!--定义全局的配置信息-->
	<profiles>
		<profile>
			<id>dev</id>  <!--开发环境-->
			<properties>
				<deploy.type>dev</deploy.type>
			</properties>
			<activation>
				<activeByDefault>true</activeByDefault>
			</activation>
		</profile>
		<profile>
			<id>pro</id> <!--生产环境-->
			<properties>
				<deploy.type>pro</deploy.type>
			</properties>
		</profile>
		<profile>
			<id>pre_pro</id> <!--预生产环境-->
			<properties>
				<deploy.type>pre_pro</deploy.type>
			</properties>
		</profile>
	</profiles>


	<dependencies>
		<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>

	<build>
		<resources>
			<resource>
				<!--deploy.type 指定部署类型：dev、pre_pro、pro-->
				<directory>src/main/resources.${deploy.type}</directory>
			</resource>
		</resources>
		<plugins>
			<plugin>
				<groupId>org.springframework.boot</groupId>
				<artifactId>spring-boot-maven-plugin</artifactId>
			</plugin>
		</plugins>
	</build>

</project>

4、打包测试

1、使用命令：mvn clean package -P参数

p:就是前面定义的profiles文件，-p后面的参数就是profile中配置的id值

例如执行命令：

F:\ideaWorkSpace\practice\springboot-maven-package-demo>mvn clean package -Ppro
