配置中心搭建（spring-cloud-config-server）

1.github建立配置庫

2.配置服務端

①建立項目

②導入jar

<!--springboot支持-->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-test</artifactId>
</dependency>

<!--eureka客戶端-->
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
</dependency>
<!--配置中心支持-->
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-config-server</artifactId>
</dependency>

③yml配置

server:
  port: 8848
eureka:
  client:
    service-url:
      defaultZone: http://localhost:7001/eureka
  instance:
    prefer-ip-address: true
spring:
  application:
    name: ruigou-config-server
  cloud:
    config:
      server:
        git:
          uri: https://github.com/xxxxx/application_config.git
          username: xxxxx
          password: xxxxxxxx

④入口

@SpringBootApplication
@EnableEurekaClient
@EnableConfigServer
public class ConfigServerApplication_8848 {
    public static void main(String[] args) {
        SpringApplication.run(ConfigServerApplication_8848.class);
    }
}

⑤測試

localhost:8848/application-plat-dev.yml

3.配置客戶端

• Eureka,configserver不須要,其餘的都是客戶端

①建立項目

②導入jar

<!--配置中心支持-->
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-config</artifactId>
</dependency>

<!--打包插件依賴-->
    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <mainClass>cn.rui97.ruigou.PlatApplication_8001</mainClass>
                    <layout>ZIP</layout>
                </configuration>
                <executions>
                    <execution>
                        <goals>
                            <goal>repackage</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

③作配置

spring:
  profiles:
      active: dev
  cloud:
    config:
      name: application-plat #github上面名稱
      profile: ${spring.profiles.active} #環境 java -jar -D xxx jar
      label: master #分支
      discovery:
        enabled: true #從eureka上面找配置服務
        service-id: ruigou-config-server #指定服務名
      #uri: http://127.0.0.1:1299 #配置服務器 單機配置
eureka: #eureka不能放到遠程配置中
  client:
    service-url:
     defaultZone: http://localhost:7001/eureka  #告訴服務提供者要把服務註冊到哪兒 #單機環境
  instance:
    prefer-ip-address: true #顯示客戶端真實ip

④打包測試

• 命令：java -jar -Dspring.profiles.active=test plat_services_8001-1.0-SNAPSHOT.jar
