Create a service provider based on the spring clould _spring-cloud

Simple steps to create a Spring-boot micro service provider. Suppose you want to create a user service:
1, the introduction of Dependence (Pom.xml):

	<dependencies>
		<dependency>
			<groupId>org.springframework.cloud</groupId>
			<artifactId>spring-cloud-starter-eureka</artifactId>
		</dependency>
		<!--other dependencies slightly ... -->
	</dependencies>

	<dependencyManagement>
		<dependencies>
			<dependency >
				<groupId>org.springframework.cloud</groupId>
				<artifactId> spring-cloud-dependencies</artifactid>
				<version>Camden.SR3</version>
				<type> pom</type>
				<scope>import</scope>
			</dependency>
		</dependencies>
	</dependencyManagement>

2. Specify the registry in the configuration file (APPLICATION.YML): Assume that there are three registered centers that comprise a highly available cluster:

Eureka:
  Client:
    serviceurl:
      defaultzone:http://192.168.0.9:58000/eureka/,http://192.168.0.10:58000 /eureka/,http://192.168.0.18:58000/eureka/
  instance:
    preferipaddress:true

3, the project configuration activates the output of the service information in the controller (through the @enablediscoveryclient annotation):

@EnableDiscoveryClient
@SpringBootApplication Public
class UserApplication {public

	static void main ( String[] args) {
		springapplication.run (userapplication.class, args);
	}
}

4, through the creation of controller to provide services:

@RestController public
class Usercontroller {
	protected final Logger Logger = Loggerfactory.getlogger (getclass ());
	
	@Autowired
	userservice userservice;

	/**
	 * Get phone number
	 * @param userId
	 * @return Phone number *
	 *
	@RequestMapping (value = "/getphonenobyuserid") based on user ID ', method = Requestmethod.get ' public
	String getphonenobyuserid (@RequestParam Integer userId) {
		logger.debug ("Getphonenobyuserid received.") userid={} ", userId);
		
		Return Userservice.getphonenobyuserid (userId);
	}

Service and other code slightly ...
5, start, check if the registry can see the User service: access to any of the three registries: Http://192.168.0.9:58000/
