一、config-server
1、配置文件:application.properties
server.port=8888
spring.cloud.config.server.git.uri=https://github.com/zzzqqq123/springcloudtest.git
spring.cloud.config.server.git.username=zhangq@webyun.cn
spring.cloud.config.server.git.password=zhangqiang@123
2、在启动类中添加注解
@EnableConfigServer
二、config-client
1、application.properties
spring.application.name=company-info-config-client
server.port=8889
2、bootstrap.properties
spring.cloud.config.uri=http://localhost:8888/
#git中的文件名称为application-dev.properties
spring.cloud.config.name=application
spring.cloud.config.profile=dev
spring.cloud.config.label=master
注意git仓库中的文件名称为:application-dev.properties
三、刷新
刷新的是客户端:http://localhost:8889/actuator/refresh(post请求)
前提是需要开启刷新端点
management.endpoints.web.exposure.include=*
# health,info,env
management.endpoint.health.show-details=always
4、实现自动刷新的功能[简单实现]
@SpringBootApplication
@EnableScheduling
public class CompanyInfoConfigClientApplication {
//定时更新数据
private final ContextRefresher contextRefresher;
CompanyInfoConfigClientApplication(ContextRefresher contextRefresher){
this.contextRefresher=contextRefresher;
}
@Scheduled(fixedRate = 10*1000,initialDelay = 10*1000)
public void refreshAuto(){
Set<String> refresh = contextRefresher.refresh();
Iterator<String> iterableSet=refresh.iterator();
System.out.println("------------------》");
while(iterableSet.hasNext()){
System.out.println(iterableSet.next());
}
}
public static void main(String[] args) {
SpringApplication.run(CompanyInfoConfigClientApplication.class, args);
}
}
5获取配置文件中的数据
package com.company.info.controller;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.cloud.context.config.annotation.RefreshScope;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
@RefreshScope//刷新
@RequestMapping("user")
public class UserController {
@Value("${user.name}")
private String name;
@GetMapping("name")
public String testValue(){
return name;
}
}
6注意:
由于config一般采用集群配置,所以我们可以采用,单个依次重启服务的方式,实现配置文件生效
