**profiles 简介**

Spring Profiles provide a way to segregate parts of your application 
    configuration and make it be available only in certain environments. 
    # profile只在特定的环境下激活，实现对应用配置的分离
    
    Any @Component, @Configuration or @ConfigurationProperties can be 
    marked with @Profile to limit when it is loaded
    # 可以在创建的时候用@Profile标记@Component, @Configuration or @ConfigurationProperties
    
    If @ConfigurationProperties beans are registered via @EnableConfigurationProperties 
    instead of automatic scanning, the @Profile annotation needs to be specified on the 
    @Configuration class that has the @EnableConfigurationProperties annotation
    # 如果@ConfigurationProperties是用@EnableConfigurationProperties创建的，则需要在
    # @EnableConfigurationProperties所在的类上加上注解@Profile

**示例**

@Configuration(proxyBeanMethods = false)
    @Profile("production")        //以下代码只在production激活时使用
    public class ProductionConfiguration {
    
        // ...
    
    }

**profile 激活**

**配置文件激活profile**

spring:
      profiles:
        active: "dev,hsqldb"  # 同时激活dev,hsqldb

**命令行激活profile**

java -jar demo.jar ----spring.profiles.active=dev,hsqldb

**设置默认激活属性**

spring:
      profiles:
        default: "dev"  #如果没有设置spring.profiles.active，则默认激活dev

**profile group**

spring:
      profiles:
        group:
          production:
          - "proddb"
          - "prodmq"
    
    # production组包含proddb、prodmq
    profile group：production
    profile：proddb、promq
    
    激活production时（--spring.profiles.active=production），可同时激活proddb、prodmq
