Second, the service registration

• Maven relies introduced

    <parent>
        <groupId>com.yk</groupId>
        <artifactId>cloud-parent</artifactId>
        <version>0.0.1-SNAPSHOT</version>
    </parent>
    <artifactId>springcloud-consul-client</artifactId>
    <dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-consul-discovery</artifactId>
        </dependency>
    </dependencies>

• Service Discovery

@SpringBootApplication(exclude = DataSourceAutoConfiguration.class)
@EnableDiscoveryClient //注册发现
public class ConsulApplication {

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

}

• yml Configuration

Spring-Cloud-= spring.application.name Consul-Client 
the server.port = 8080 

# Consul connection configuration of the server 
# Consul host address 
spring.cloud.consul.host = http://192.168.100.129 
# Consul service port 
spring.cloud 8500 = .consul.port 

# HealthCheck adjustment path it passed to the server Consul, help callback, if you do not configure the service will be registered on the unsuccessful 
spring.cloud.consul.discovery.healthCheckPath = / check 

host address # this is the default service machine 
spring.cloud.consul.discovery.hostname = 192.168.0.102

• Test Demo

@RestController 
public class DiscoveryClientController { 
    @Autowired 
    Private DiscoveryClient discoveryClient; 

    @Value ( "spring.application.name $ {}") 
    Private ApplicationName String;

    @GetMapping("/check")
    public String check() {

    }

}

Third, start

• Start two clients

• By ip: 8500 query Consul ui page

• View examples
