SpringCloud（6）-配置中心

SpringCloud的配置服务

配置服务

1. pom.xml中加入以下依赖

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

2. 在启动类上加入@EnableConfigServer

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

3. application.properties的配置

   spring.application.name=provider
   server.port=84
   spring.cloud.config.server.git.uri=https://github.com/forezp/SpringcloudConfig/
   spring.cloud.config.server.git.search-paths=respo
   spring.cloud.config.label=master
   eureka.client.service-url.defaultZone=http://master:81/eureka/
   

4. 启动程序

config客户端

1. pom.xml加入以下依赖

   <dependency>
       <groupId>org.springframework.cloud</groupId>
       <artifactId>spring-cloud-starter-config</artifactId>
   </dependency>
   

2. 必须在bootstrap.properties中配置，若没有，自行创建

   #这个必须与你配置文件的名称一样 这个就是 congig-client-dev.properties
   spring.application.name=config-client
   
   feign.hystrix.enabled=true
   spring.cloud.config.label=master
   spring.cloud.config.profile=dev
   eureka.client.service-url.defaultZone=http://master:81/eureka/
   spring.cloud.config.discovery.enabled=true
   spring.cloud.config.discovery.service-id=provider
   server.port=85
   

3. 程序中使用

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