2、从git 配置中心获取配置内容，必须将config client 端的配置文件命名为 bootstrap.yml
server:
port: 1006
eureka:
client:
service-url:
#eureka 客户端配置
defaultZone: http://localhost:1005/eureka/
register-with-eureka: true
fetch-registry: true
spring:
application:
#应用名称，需要和git 上存的配置文件前缀一致
name: member
cloud:
#配置中心客户端配置
config:
#环境名称，需要和git上存的配置文件命名中的环境一致 eg:member-dev.yml
profile: dev
discovery:
#配置中心server 在eureka注册 的服务名称
service-id: config-server
enabled: true
#开启所有端点手动根据配置中心配置 刷新
management:
endpoints:
web:
exposure:
#include: "*"
include: /refresh #这是配置刷新路径
3、系统主类，开启eureka客户端
@SpringBootApplication
@EnableEurekaClient
public class MemberApplication {
public static void main(String[] args) {
SpringApplication.run(MemberApplication.class, args);
}
}
4、需要使用配置中心的文件地方，开启@Configuration(有人说不用这个注解），开启手动刷新注解 @RefreshScope, 当git 中配置文件内容变更，只需要 post 方式 访问当前这个节点 eg: http://127.0.0.1:1006/actuator/refresh 刷新即可
@RestController
@Configuration
@RefreshScope //开启手动刷新配置文件的注解
public class IndexController {
#git配置文件中一个属性的读取
@Value("${userAge}")
private StringuserAge;
@RequestMapping("/get_user_age")
public String getUserAge(){
return userAge;
}
}
