对于consul的查询无效实例并清除

@RestController
public class ApiController {
    private static Logger log = LoggerFactory.getLogger(ApiController.class);
    @Autowired
    private ConsulClient consulClient;

    /**
     * 剔除所有无效的服务实例
     */
    @RequestMapping(value = "/CheakCleanService", method = RequestMethod.GET)
    public void CheakCleanService() {
        log.info("***********************consul上无效服务清理开始*******************************************");
        //获取所有的services检查信息
        Iterator<Map.Entry<String, Check>> it = consulClient.getAgentChecks().getValue().entrySet().iterator();
        Map.Entry<String, Check> serviceMap = null;
        while (it.hasNext()) {
            //迭代数据
            serviceMap = it.next();
            //获取服务名称
            String serviceName = serviceMap.getValue().getServiceName();
            //获取服务ID
            String serviceId = serviceMap.getValue().getServiceId();
            log.info("服务名称 :{}**服务ID:{}", serviceName, serviceId);
            //获取健康状态值  PASSING：正常  WARNING  CRITICAL  UNKNOWN：不正常
            log.info("服务 :{}的健康状态值：{}", serviceName, serviceMap.getValue().getStatus());
            if ( serviceMap.getValue().getStatus() == Check.CheckStatus.CRITICAL) {
                log.info("服务 :{}为无效服务，准备清理...................", serviceName);
                consulClient.agentServiceDeregister(serviceId);
            }
        }
    }
}
