springcloud-config实现_springcloud-config如何实现-优快云博客

本文链接：https://blog.youkuaiyun.com/x_u_xiang/article/details/122923452

本文介绍了如何使用Spring Cloud搭建配置中心，包括创建config服务端项目cloud-config-server3344，配置pom.xml、yml文件及主启动类。然后创建config客户端项目cloud-config-client3355，配置pom.xml、application.yml和bootstrap.yml，以及主启动类。通过配置，客户端能够从配置中心获取并展示配置信息。

具体实现

在gitee新建一个仓库，加几个配置文件。

主启动类

package com.xx.job.cloudconfigserver;

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

@EnableConfigServer
@EnableEurekaClient
@SpringBootApplication
public class CloudConfigServerApplication {

	public static void main(String[] args) {
		SpringApplication.run(CloudConfigServerApplication.class, args);
	}

}

访问 http://127.0.0.1:3344/config-test.yml 可以看到配置文件的具体信息。

application.yml配置

server:
  port: 3355
spring:
  application:
    name: cloud-config-client3355


eureka:
  client:
    #表示是否将自己注册进EurekaServer，默认为true
    register-with-eureka: true
    # 是否从EurekaServer抓取已有的注册信息，默认为false，单节点无所谓，集群必须设置为true,才能配合ribbon使用负载均衡
    fetch-registry: true
    service-url:
      defaultZone: http://localhost:7001/eureka

bootstrap配置

spring:
  cloud:
    config:
      uri: http://localhost:3344 #config总控中心搭建
      label: master # git分支
      profile: test # 环境  dev  test   prod
      name: config  #配置文件名

主启动类

package com.xx.job.cloudconfigclient3355;

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


@EnableEurekaClient
@SpringBootApplication
public class CloudConfigClient3355Application {

    public static void main(String[] args) {
        SpringApplication.run(CloudConfigClient3355Application.class, args);
    }

}

controller访问配置文件

import org.springframework.beans.factory.annotation.Value;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class ConfigController {

    @Value("${config.info}")
    private String info;

    @RequestMapping("/getInfo")
    public String getInfo(){
        return info;
    }
}
