package com.yj.config;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;

@SpringBootApplication
@EnableEurekaClient
public class ConfigClientApplication {
	public static void main(String[] args) {
		SpringApplication.run(ConfigClientApplication.class, args);
	}
}

bootstrap.properties

server.port=8012

spring.application.name=config-client
eureka.client.serviceUrl.defaultZone=http://admin:123456@peer1:8001/eureka,http://admin:123456@peer2:8002/eureka
eureka.instance.prefer-ip-address=true
eureka.instance.instance-id=${spring.cloud.client.ipAddress}:${server.port}
eureka.instance.hostname=${spring.cloud.client.ipAddress}

spring.cloud.config.discovery.enabled=true
spring.cloud.config.discovery.service-id=config-server
spring.cloud.config.label=config-client
spring.cloud.config.profile=dev
spring.cloud.config.username=admin
spring.cloud.config.password=123456

spring.rabbitmq.host=192.168.37.140
spring.rabbitmq.port=5672
spring.rabbitmq.username=guest
spring.rabbitmq.password=guest

部署，在服务器/opt/springcloud/config-repo/config-client路径下放一个config-client-dev.properties的配置文件

config.testStr={cipher}9fdd3c1aee0d95551f7829ba9d7aa02dc096930b33e178c14dacf3502c9d79b2

加密串来源于http://admin:[email protected]:8010/encrypt/ 端点的加密结果。

启动端口为8010,8011的server实例，8012,8013的client实例

 部署成功，

①请求http://192.168.37.140:8012/hiConfig，显示hiConfig

②修改配置文件加密串240552d25edcbac3f43f4a0262cc718e5a862cb54db548956f2dbf1e40be8415，然后请求

http://admin:[email protected]:8010/bus/refresh刷新接口，等待刷新成功后，重复请求步骤1，显示hiYj
