十、springcloud之Consul登出例項

@Autowired  //com.ecwid.consul.v1.ConsulClient

    private ConsulClient consulClient;

    @PostMapping("/clear/{serviceId}")

    public void clear(@PathVariable String serviceId) {

        consulClient.agentServiceDeregister(serviceId);

    }

• 先通過consulClient.getHealthServices(serviceId, false, null)根據serviceId來獲取服務例項清單
• 遍歷例項清單中有不是PASSING狀態的例項，就呼叫client.agentServiceDeregister(serviceId)來剔除

  public void clear(@PathVariable String id) {
  
          List<HealthService> response = consulClient.getHealthServices(id, false, null).getValue();
  
          for(HealthService service : response) {
  
              // 建立一個用來剔除無效例項的ConsulClient，連線到無效例項註冊的agent
  
              ConsulClient clearClient = new ConsulClient(service.getNode().getAddress(), 8500);
  
              service.getChecks().forEach(check -> {
  
                  if(check.getStatus() != Check.CheckStatus.PASSING) {
  
                      logger.info("unregister : {}", check.getServiceId());
  
                      clearClient.agentServiceDeregister(check.getServiceId());
  
                  }
  
              });
  
          }
  
      }

  client連線的agent必須是serviceId註冊的agent
