SpringCloud service discovery -Eureka

1, Eureka server cluster development

　　1, first create a parent project

　　　　If not an ordinary demo, there are other configuration, you need to pay attention if the service is probably not open up dependent parent may be required <dependencyManagement> label.

　　2, create two sub-projects

　　　　1, import-dependent

　　　　　<dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
            <version>2.1.2.RELEASE</version>
        </dependency>

　　2, the configuration file application.yml

# Built-in tomcat service start listening port number
server:
  port: 6002

#EurekaServer Configuration
eureka:
  instance:
    hostname: eureka6002 #EurekaServer name
  client:
    the Register the -with-Eureka: false # This EurekaServer not registered to other registries
    FETCH -registry: false        # server is not pulling information from other centers Center
    service-url:
      defaultzone: HTTP: // eureka6001.com:6001/eureka # registry access address 

-------------------------------- -------

# Built-in tomcat service start listening port number 
Server: 
  Port: 6001 
#EurekaServer configuration 
Eureka: 
  instance: 
    hostname: eureka6001 
  Client: 
    the Register-with-Eureka: false # This EurekaServer not registered to other registries 
    fetch-registry: false # is not pulls information from other central server center 
    Service-url: 
      defaultzone: http://eureka6002.com:6002/eureka # registry access address

　　3, the master boot class

@SpringBootApplication // This is the main startup class mark
@EnableEurekaServer // mark which is EurekaServer
public class AppStart2 {

    public static void main(String[] args) {
        SpringApplication.run(AppStart2.class, args);
    }
}

2, micro-service configuration

　　1, introducing dependent, dependent on the above

　　2, the configuration added application.yml

eureka:
  client:
    the Register the -with-Eureka: to true # allowed to register to EurekaServer
    FETCH -registry: to true        # server pulls information from other centers Center
    service-url:
      defaultzone: HTTP: // eureka6002.com:6002/eureka, http://eureka6001.com : 6001 / Eureka # to access the registry

　　3, the master boot class

@SpringBootApplication
@EnableEurekaClient // mark this is a Euerka client, you must write
public class ProductProvider_8001 {
    public static void main(String[] args) {
        SpringApplication.run(ProductProvider_8001.class,args);
    }
}

3, start the project

　　Visit http: // localhost: 6001 / and http: // localhost: 6002 /
