SpringCloud读取自定义配置文件

1、使用springApplicationBuilder指定；
配置文件放到resource目录下

@SpringBootApplication
public class HelloWorldApplication {
    public static void main(String[] args) {
        new SpringApplicationBuilder(HelloWorldApplication.class).properties("spring.config.location=classpath:/abc.yml").run(args);
    }
}

2、读取配置文件中变量

配置文件定义变量值

server:
  port: 8088
config:
    name: cc

@Value("${config.name}")
String name;
@GetMapping("/helloworld")
public String helloWorld() {
    return "hello"+name;
}

3、设置不同环境变量

server:
  port: 8088
spring:
  profiles: linux
config:
    name: cc
---
spring:
  profiles: windows
config:
  name: dd

@SpringBootApplication
public class HelloWorldApplication {
    public static void main(String[] args) {
        new SpringApplicationBuilder(HelloWorldApplication.class).properties("spring.config.location=classpath:/abc.yml","spring.profiles.active=windows").run(args);
    }
}
