spring提供了多环境配置文件的功能,只需要根据配置文件后缀即可加载对应的配置文件

spring: profiles: # 修改后缀即可加载对应的配置 active: dev |
还需要准备好对应的配置文件
但是这怎样写死的 spring.profiles.active 属性在使用idea给不同环境打包时每次都需要手动修改,可以使用maven提供的动能实现自动映射配置属性。
在pom.xml文件中主要添加以下配置
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 |
<!--配置多环境打包--> <profiles> <!--开发环境--> <profile> <id>dev</id> <properties> <!--自定义的属性--> <spring.profiles.active>dev</spring.profiles.active> </properties> <activation> <!--如果不指定,则默认使用dev开发环境配置--> <activeByDefault>true</activeByDefault> </activation> </profile> <!-- 测试环境--> <profile> <id>test</id> <properties> <spring.profiles.active>test</spring.profiles.active> </properties> </profile> <!--生产环境--> <profile> <id>prod</id> <properties> <spring.profiles.active>pro</spring.profiles.active> </properties> </profile> </profiles> <build> <finalName>${project.name}</finalName> <resources> <resource> # mavan要对哪个目录解析 ${} 标签 <directory>${project.basedir}/demo/src/main/resources</directory> # 是否过滤 <filtering>true</filtering> </resource> </resources> </build> |
在添加了上述配置后,在pom.xml文件中右击 --> Maven --> 重新加载项目,就能看到右边多了一些配置
然后修改application.yml文件的配置
1 2 3 4 |
spring: profiles: # 修改后缀即可加载对应的配置 active: ${spring.profiles.active} |
选中想打包的环境
打包后查看实际打出来的包配置文件的属性是否真正加载了
可以看到正是所选的 pro 环境,这样就不用每次打包时都手动修改 spring.profiles.active 属性,只需要在打包时勾选一下maven对应的profiles属性即可
