十、springcloud之Consul注销实例

@Autowired  //com.ecwid.consul.v1.ConsulClient
    private ConsulClient consulClient;

    @PostMapping("/clear/{serviceId}")
    public void clear(@PathVariable String serviceId) {
        consulClient.agentServiceDeregister(serviceId);
    }

• 先通过consulClient.getHealthServices(serviceId, false, null)根据serviceId来获取服务实例清单
• 遍历实例清单中有不是PASSING状态的实例，就调用client.agentServiceDeregister(serviceId)来剔除

  public void clear(@PathVariable String id) {
          List<HealthService> response = consulClient.getHealthServices(id, false, null).getValue();
          for(HealthService service : response) {
              // 创建一个用来剔除无效实例的ConsulClient，连接到无效实例注册的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连接的agent必须是serviceId注册的agent
