Spring Boot 入门微服务之 Config Server 统一配置中心

Posted 2020-09-27

一、目录结构

二、pom文件

<!-- 配置服务依赖 -->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-config-server</artifactId>
        </dependency>
        <!-- Eureka 客户端依赖-->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-eureka</artifactId>
        </dependency>

<dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>${spring-cloud.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

spring-cloud-dependencies 移至microservice中的pom文件

 

三、YML的配置

1.bootstrap.yml

spring:
  profiles:
    active: native #配置服务器使用本地配置，默认git配置
  application:
    name: micro-service-config # 在Eureka中注册的服务名
    
eureka:
  instance:
    non-secure-port: ${server.port:8763} # 环境变量中有值则使用环境变量中的值，如果没有的话默认8080端口
    metadata-map:
      instanceId: ${spring.application.name}:${random.value} #配置在Eureka server中的ID
  client:
    service-url:
      defaultZone : http://localhost1:8761/eureka/,http://localhost2:8762/eureka/  #注册到Eureka Server   

2.application.yml

spring:
  cloud:
    config:
      server:
        native:
          search-locations: classpath:/config #配置文件所在位置
server:
  port: 8763
  

四、启动microservice-config

package com.nc.cloud.microservice.config;

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;

@SpringBootApplication
@EnableConfigServer //开启配置服务器的支持
@EnableEurekaClient // 开启 Eureka 客户端的支持
public class ConfigApplication {
    
    public static void main(String[] args) {
        SpringApplication.run(ConfigApplication.class, args);
    }
}
