Springcloud-配置中心config
一、添加依赖
<dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-config-server</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-actuator</artifactId></dependency>
二、添加注解@EnableConfigServer
@SpringBootApplication
@EnableConfigServer
public class MainApplicationCenter3344 {public static void main(String[] args) {SpringApplication.run(MainApplicationCenter3344.class, args);}
}
三、添加配置
server:port: 3344spring:application:name: cloud-config-center #注册进Eureka服务器的微服务名cloud:config:server:git:uri: https://github.com/djftjfs/springcloud-config.git #GitHub上面的git仓库名字####搜索目录search-paths:- springcloud-configusername: xxxpassword: xxx####读取分支label: master#服务注册到eureka地址
eureka:client:service-url:defaultZone: http://localhost:7001/eureka
四、测试http://config-3344.com:3344/master/config-dev.yml

五、配置读取规则
label : 分支名 ; application : 服务名 ; profile : 环境(dev/test/prod)
/{label}/{application}-{profile}.yml
eg:http://config-3344.com:3344/master/config-dev.yml
/{application}-{profile}.yml
eg:http://config-3344.com:3344/config-dev.yml
/{application}/{profile}/{label}
eg:http://config-3344.com:3344/config/dev/master
四、客户端配置
1、添加依赖
<dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-config</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-actuator</artifactId></dependency>
2、创建bootstrap.yml 配置文件
server:port: 3355spring:application:name: config-clientcloud:#Config客户端配置config:label: master #分支名称name: config #配置文件名称profile: dev #读取后缀名称 上述3个综合:master分支上config-dev.yml的配置文件被读取http://config-3344.com:3344/master/config-dev.ymluri: http://localhost:3344 #配置中心地址k#服务注册到eureka地址
eureka:client:service-url:defaultZone: http://localhost:7001/eureka
五、动态刷新(手动)
1、在客户端模块添加依赖
<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-actuator</artifactId></dependency>
2、在bootstrap.yml 文件添加如下内容
# 暴露监控端点
management:endpoints:web:exposure:include: "*"
3、在业务类上添加@RefreshScope
@RestController
@RefreshScope
public class ConfigClientController
{@Value("${config.info}")private String configInfo;@GetMapping("/configInfo")public String getConfigInfo(){return configInfo;}
}
4、手动刷新(必须post)
执行 curl -X POST "http://localhost:3355/actuator/refresh"
六、动态刷新(自动)
1、在之前基础上在服务端和客户端上添加依赖
<!--添加消息总线RabbitMQ支持--><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-bus-amqp</artifactId></dependency>
2、服务端添加配置
#rabbitmq相关配置rabbitmq:host: 192.168.xxx.165port: 5672username: adminpassword: 123##rabbitmq相关配置,暴露bus刷新配置的端点
management:endpoints: #暴露bus刷新配置的端点web:exposure:include: 'bus-refresh'
3、客户端只需添加RabbitMQIP相关配置即可
4、当在git端修改完配置之后,只需在服务端执行curl -X POST "http://localhost:3344/actuator/bus-refresh" 即可刷新全部客户端
七、精确刷新
只需在上面通知上添加服务注册名及端口号即可
curl -X POST "http://localhost:3344/actuator/bus-refresh/config-client:3355"
