SpringCloudConfig快速入門-配置中心的搭建

server端

1.pom中添加依賴

		<dependency>
			<groupId>org.springframework.cloud</groupId>
			<artifactId>spring-cloud-config-server</artifactId>
			<version>2.0.1.RELEASE</version>
		</dependency>

2.啓動類

添加註解@EnableConfigServer

3.配置文件

application.yml配置文件

server:
  port: 5000
spring:
  application:
    name: config-server
  cloud:
    config:
      server:
        git:
        ##定義去拉取本地配置的地址
          uri: D:\\code\\item\\springcloud\\day02_config\\config-server\\src\\main\\resources\\configs
        ##遠程拉取配置文件的配置
        ##uri: https://github.com/936981178/springcloudconfig.git     # 配置git倉庫的地址
        ##search-paths: config-repo  # git倉庫地址下的相對地址，可以配置多個，用,分割。
        ##username:                  # git倉庫的賬號
        ##password:                  # git倉庫的密碼
management:
  endpoints:
    web:
      exposure:
        include: "*"

配置eurekaserver文件
一般都有三個環境的配置文件
```

spring:
  application:
    name: eureka-peer

server:
  port: 10000

eureka:
  instance:
    hostname: dev
    instance-id: dev
  client:
    fetch-registry: false
    register-with-eureka: false
    service-url:
      defaultZone: http://localhost:10000/eureka/
  server:
    wait-time-in-ms-when-sync-empty: 0
    enable-self-preservation: true
    peer-eureka-nodes-update-interval-ms: 10000

4.git初始化

打開git初始化：
git init
git add .
git commit -m “frist commit”

啓動,訪問http://localhost:5000/eurekaserver/dev

可讀取到配置文件內容

eureka從配置中心拉取配置(config_client端)

1.pom依賴

		<dependency>
			<groupId>org.springframework.cloud</groupId>
			<artifactId>spring-cloud-config-client</artifactId>
			<version>2.0.1.RELEASE</version>
		</dependency>

2.配置文件

config的相關配置是要先於application.properties的，所以需要使用bootstrap.yml,其配置文件的加載先於application.properties。

bootstrap,yml

server:
  port: 10000

spring:
  application:
    ##config服務configs的文件名對應
    name: eurekaserver
  cloud:
    config:
      name: eurekaserver
      uri : http://localhost:5000/
  profiles:
    ##config服務configs中對應文件名後面的環境
    active: dev

啓動訪問http://localhost:10000/

測試

同eureka-server一樣,將上次的eureka-client交給config配置中心管理

配置文件

在config服務中新建helloclient-dev.yml配置文件

name: mcw
age : 22

eureka:
  client:
    service-url:
      defaultZone: http://127.0.0.1:10000/eureka/

將配置文件添加到git中

git add helloclient-dev.yml
git commit -m "helloclient commit"

在eureka-client服務添加測試代碼

public class Teacher {

    private String  name;
    private int age;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

}

@RestController
public class HelloEurekaController {

    @Value("${name}")
    private String name;

    @Value("${age}")
    private int age;

    @GetMapping("")
    public Object index(){
        Teacher teacher = new Teacher();
        teacher.setAge(this.age);
        teacher.setName(this.name);
        return teacher;
    }
    
}

啓動訪問http://localhost:8001/
