老规矩 直接上代码

2./config-client/src/main/resources/bootstrap.properties

spring.application.name=foo
spring.cloud.config.profile=test
spring.cloud.config.label=master
spring.cloud.config.uri=http://localhost:8888/
注意 这里我配置的 profile 是test 

3.client代码
package com.djl.springcloud.config.client;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@SpringBootApplication
@RestController
public class Application {
@Value("${name}")
String bar;

@RequestMapping("/")
String hello() {
return "Hello " + bar + "!";
}

public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}


上面 bar 的是通过读取配置文件注入进来的 我们看结果
4.访问：http://localhost:8080/



5.对比git上的文件

那其他环境的呢~~ 咱们随便看个其他配置

总之每个环境的配置是不一样的，应用程序会给根据你的配置来读取~~~
