spring cloud 之 config-client

老规矩 直接上代码

1.pom.xml

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

spring.application.name=foo spring.cloud.config.profile=testspring.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@RestControllerpublic 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~~~
