Java后端使用mvn区分dev,pro,local环境

一，pom.xml配置

local代表本地环境
dev代表开发环境
pro代表生产环境
设置默认环境使用dev

 <!--环境配置-->
    <profiles>
        <profile>
            <id>local</id>
            <properties>
                <!-- 环境标识，需要与配置文件的名称相对应 -->
                <activatedProperties>local</activatedProperties>
            </properties>
        </profile>

        <profile>
            <id>dev</id>
            <properties>
                <activatedProperties>dev</activatedProperties>
            </properties>
            <activation>
                <!-- 默认环境 -->
                <activeByDefault>true</activeByDefault>
            </activation>
        </profile>

        <profile>
            <id>pro</id>
            <properties>
                <activatedProperties>pro</activatedProperties>
            </properties>
        </profile>
    </profiles>


    <build>
        <resources>
            <resource>
                <!--配置文件路径  -->
                <directory>src/main/resources</directory> <!--这里对应项目存放配置文件的目录-->
                <!--开启filtering功能  -->
                <filtering>true</filtering>
            </resource>
        </resources>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <executions>
                    <execution>
                        <goals>
                            <!--创建一个自动可执行的jar或war文件 -->
                            <goal>repackage</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

二，yml文件配置

spring:
  profiles:
    active: @activatedProperties@

三，mvn编译命令

-P dev   指定使用dev配置
-P pro   指定使用pro配置
-P local 指定使用local配置

mvn clean install package -P pro -Dmaven.test.skip=true

如不指定 默认使用dev配置 

mvn clean install package -Dmaven.test.skip=true

四，验证

启动后会输出使用的配置
