建立統一管理的 Config Server

建立一個 config-server 專案

使用到的組件如下

主要依賴是 spring-cloud-config-server

dependencies {
    compile('org.springframework.cloud:spring-cloud-config-server')
    testCompile('org.springframework.boot:spring-boot-starter-test') 
}

application.properties

spring.cloud.config.server.git.uri=D:/springcloud/config-repo
server.port=8888

• spring.cloud.config.server.git.uri
  設定應用起動時從哪裡讀取設定檔，可以從Github，也可以從本地Git檔案
  ​
  D:/springcloud/config-repo資料夾放的檔案
  application.yml

server.port: ${PORT:${SERVER_PORT:0}}
info.id: ${spring.application.name}
debug: true
spring.sleuth.log.json.enabled: true
logging.pattern.console: "%clr(%d{yyyy-MM-dd HH:mm:ss.SSS}){faint} %clr(%5p) %clr(${PID:- }){magenta} %clr(---){faint} %clr([trace=%X{X-Trace-Id:-},span=%X{X-Span-Id:-}]){yellow} %clr([%15.15t]){faint} %clr(%-40.40logger{39}){cyan} %clr(:){faint} %m%n%wex"

reservation-service.properties

server.port=${PORT:8000}
message=HELLO world!
spring.cloud.stream.bindings.input=reservations

起動程式
ConfigServerApplication.java

package com.example;

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

@EnableConfigServer
@SpringBootApplication
public class ConfigServerApplication {

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

記得加上@EnableConfigServer就可以啟動ConfigServer的功能了

起動 Config-Server 後可以訪問 http://localhost:8888/reservation-service/master 就可以取得設定相關資料
