解决consul覆盖注册

默认注册consul的服务id为服务名-端口号，相同的服务名和端口号注册会覆盖

解决方式：

1.自定义Consul注册Id

import com.ecwid.consul.v1.ConsulClient;
import org.springframework.cloud.consul.discovery.ConsulDiscoveryProperties;
import org.springframework.cloud.consul.discovery.HeartbeatProperties;
import org.springframework.cloud.consul.discovery.TtlScheduler;
import org.springframework.cloud.consul.serviceregistry.ConsulRegistration;
import org.springframework.cloud.consul.serviceregistry.ConsulServiceRegistry;

/**
 * @describe: 自定义consul注册id
 * @author: zhuCw
 * @date: 2019/4/25 17:57
 */
public class RpsConsulServiceRegistry extends ConsulServiceRegistry {
  public RpsConsulServiceRegistry(
      ConsulClient client,
      ConsulDiscoveryProperties properties,
      TtlScheduler ttlScheduler,
      HeartbeatProperties heartbeatProperties) {
    super(client, properties, ttlScheduler, heartbeatProperties);
  }

  @Override
  public void register(ConsulRegistration reg) {
    // 重新设计id，此处用的是名字也可以用其他方式例如instanceid、host、uri等
    reg.getService()
        .setId(
            reg.getService().getName() + "-" + reg.getService().getAddress() + "-" + reg.getPort());
    super.register(reg);
  }
}

2. 放入容器

import com.ecwid.consul.v1.ConsulClient;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.cloud.consul.discovery.ConsulDiscoveryProperties;
import org.springframework.cloud.consul.discovery.HeartbeatProperties;
import org.springframework.cloud.consul.discovery.TtlScheduler;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

/**
 * @describe: TODO
 * @author: zhuCw
 * @date: 2019/4/25 17:57
 */
@Configuration
public class RpsConsulServiceRegistryConfig {
  @Autowired(required = false)
  private TtlScheduler ttlScheduler;

  @Bean
  public RpsConsulServiceRegistry consulServiceRegistry(
      ConsulClient consulClient,
      ConsulDiscoveryProperties properties,
      HeartbeatProperties heartbeatProperties) {
    return new RpsConsulServiceRegistry(
        consulClient, properties, ttlScheduler, heartbeatProperties);
  }
}
