带有${key}的配置文件：
/Spring-Env/src/main/resources/application.yml
#激活的环境配置
spring:
profiles:
active: ${spring.profiles.active}
#端口
server:
port: ${server.port}
配置文件一：
src/main/resources/env/pro/application.yml
server:
port: 8083
env: pro ftp: hello pro spring:
profiles:
active: pro
配置文件二：
src/main/resources/env/dev/application.yml
server:
port: 8084 ftp: hello dev spring:
profiles:
active: dev
配置文件三：
src/main/resources/env/sit/application.yml
server:
port: 8082
env: sit
ftp: hello sit spring:
profiles:
active: sit
运行Spring boot主程序即可实现！
测试程序：
@RestController
public class SampleController { @Autowired
private Environment env; @RequestMapping("/sample")
public String sample(){ return "spring boot success ! and profile is ==>"+
env.getProperty("spring.profiles.active")+"=====>"+
env.getProperty("ftp");
}
}
maven打包：
mvn clean install -P promaven打包：
mvn clean install -P sit注：maven打包也可以使用eclipse的maven插件
