SpringBoot初级开发--多环境配置的集成(9)

在Springboot的开发中，我们经常要切换各种各样的环境配置，比如现在是开发环境，然后又切换到生产环境，这个时候用多环境配置就是一个明智的选择。接下来我们沿用上一章的工程来配置多环境配置工程。

1.准备多环境配置文件

这里我们准备三个配置文件
在这里插入图片描述
application.properties是通用统一的配置文件，内容如下

server.port=8088

spring.profiles.active=@profile.active@

application-dev.properties是开发用的配置文件，内容如下

server.port=8088

first.web.welcome.name="now is dev"

spring.datasource.dynamic.hikari.pool-name=example-cp
spring.datasource.dynamic.hikari.max-pool-size=20
spring.datasource.dynamic.hikari.max-lifetime=17170000
spring.datasource.dynamic.hikari.connectionInitSql=set names utf8mb4

spring.datasource.dynamic.primary=test
#test???
spring.datasource.dynamic.datasource.test.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.dynamic.datasource.test.url=jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf8&serverTimezone=Asia/Shanghai
spring.datasource.dynamic.datasource.test.username=root
spring.datasource.dynamic.datasource.test.password=root

spring.datasource.dynamic.datasource.test.hikari.max-pool-size=12
spring.datasource.dynamic.datasource.test.hikari.max-lifetime=15000000



info.application.name="@project.name@"
info.application.description="@project.description@"
info.application.version="@project.version@"

management.server.port=52001

management.endpoints.web.exposure.include=*

management.info.env.enabled=true

#spring.elasticsearch.rest.uris=http://10.10.52.155:9200
#spring.elasticsearch.rest.username=
#spring.elasticsearch.rest.password=
#spring.elasticsearch.rest.connection-timeout=10000
#spring.elasticsearch.rest.read-timeout=30000


spring.elasticsearch.uris=http://10.10.52.155:9200
spring.data.elasticsearch.repositories.cluster-name=elasticsearch
spring.data.elasticsearch.repositories.cluster-nodes=10.10.52.155:9300


spring.mvc.pathmatch.matching-strategy=ANT_PATH_MATCHER

application-pro.properties作为生产配置，和上面的一样的。

2.修改POM.xml文件配置

1.增加profiles和resources的多配置属性的修改，整个pom文件的内容如下。profiles增加了dev,pro两个配置。resoucces包含了编译要包含的文件，配置文件按照，你选择的哪一版本配置加入配置文件。

    </build>

</project>

2.修改完配置记得更新idea的maven配置，这样就出现了profiles，你可以选择是dev安装发包，还是pro安装发包。
在这里插入图片描述
选择好pro版本后，我们直接install。然后maven就把与pro相关的配置全部打包成一个包。

这样按照多版本配置去打包就实现了。如果springboot要按版本运行，可以直接把配置加入这里
