Springcloud之搭建Spring Cloud Config

对Spring Cloud Config有所了解的话，就会知道，Spring Cloud Config注册到eureka后，其他服务会通过eureka找到Spring cloud config，并在Config服务中读取自己的配置文件。

此配置文件可以通过GIT服务器获取、在所在应该的目录中获取、在所在服务器中的文件夹中获取。

1.maven依赖

2.application.yml配置

如果想将配置文件放到项目中文件，可以用一下配置

server:
  port: 2003

spring:
  application:
    name: xichuan-config-server
  profiles:
    active: native

  #本地测试使用
  context-path: /config

eureka:
  instance:
    preferIpAddress: true
    leaseRenewalIntervalInSeconds: 1
    leaseExpirationDurationInSeconds: 2
    nonSecurePort: ${server.port}
  client:
    serviceUrl:
      defaultZone: http://localhost:2001/eureka/

management:
  security:
    enabled: false

如果想让配置文件放到服务器中某一目录下，如/root/xichuan/configs目录下，可以使用以下配置：

server:
  port: 2003

spring:
  application:
    name: xichuan-config-server
  profiles:
    active: native
##云服务器使用
  cloud:
    config:
      server:
        native:
          searchLocations:
            file:/root/xichuan/configs
    inetutils:
      ignoredInterfaces:
        - eth0

eureka:
  instance:
    preferIpAddress: true
    leaseRenewalIntervalInSeconds: 1
    leaseExpirationDurationInSeconds: 2
    nonSecurePort: ${server.port}
  client:
    serviceUrl:
      defaultZone: http://localhost:2001/eureka/

management:
  security:
    enabled: false

3.启动类添加注解

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
@EnableEurekaClient
public class XichuanConfigServerApplication {

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

 

我们可以看到eureka已经注册了config-server服务

 

项目的启动顺序是：1.eureka，2.config-server，3.zuul(可选)，4.服务
