Config:远程配置实战测试

接下来我们把Eureka7001和Dept8001的配置文件放到git上面远程获取一下试试:

1.新建文件config-eureka.yml和config-dept.yml并上传到git远程仓库。

server:
  port: 7001

#spring的配置
spring:

    hostname: localhost7001 #Eureka服务端的实例名称
  client:
    register-with-eureka: false  #表示是否向eureka注册中心注册自己
    fetch-registry: false  #fetch-registry如果false,则表示自己为注册中心
    service-url: #监控页面
      defaultZone: http://localhost:7002/eureka/,http://localhost:7003/eureka/

#spring配置
spring:

  application:
    name: springcloud-config-dept
  datasource:
    type: com.alibaba.druid.pool.DruidDataSource
    driver-class-name: org.gjt.mm.mysql.Driver
    url: jdbc:mysql://123456789:3306/db01?useUnicode=true&serverTimezone=GMT%2B8&useSSL=false

    instance:
      instance-id: springcloud-provider-dept8001 #修改eureka上的默认描述信息
      prefer-ip-address: true #true,可以显示服务的ip地址

server:
  port: 8001

#mybatis配置

3.新建springcloud-config-eureka-7001项目,并复制依赖和添加config的依赖。

            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-devtools</artifactId>
        </dependency>
    </dependencies>

</project>

4.新建配置文件bootstrap.yml和application.xml。

spring:
  cloud:
    config:
      name: config-eureka
      label: master
      profile: dev
      uri: http://localhost:3344
spring:
  application:
    name: springcloud-config-eureka-7001

5.把启动类也复制过来。

6.启动3344和7001进行测试。

image.png

7001正常访问:

7.安装上面同样的步骤,新建springcloud-config-dept-8001。

image.png

8.启动测试。

image.png

进入localhost:7001看看服务有没有被注册进来:

image.png

服务已经被注册进来了没有问题,接下来我们调用接口测试一下:

image.png


接口调用成功也没有问题,接下来我们远程修改配置文件,让他调用db02数据库里面的内容:

重启项目或者热部署之后测试:

成功远程修改配置文件,更改数据库连接。
