   eureka、client版本为springboot 2.0.x，禁用服务时报：
   java.io.FileNotFoundException: http://192.168.1.8:8081/service-registry/instance-status

   你搜索example里的demo，可以发现
   service-registry/instance-status 这个接口的实现来自ServiceRegistryEndpoint类
   较低的版本里，可能没有这个类的实现

   所以，我建议，这里摘除服务可以使用https://github.com/Netflix/eureka/wiki/Eureka-REST-operations

   我们团队是使用这个接口来操作的

   Take instance out of service	PUT /eureka/v2/apps/appID/instanceID/status?value=OUT_OF_SERVICE	HTTP Code:* 200 on success* 500 on failure
   Move instance back into service (remove override)	DELETE /eureka/v2/apps/appID/instanceID/status?value=UP (The value=UP is optional, it is used as a suggestion for the fallback status due to removal of the override)	HTTP Code:* 200 on success* 500 on failure

   重写一下那个enable和disable调用的controller，可能更通用一些.

   	@RequestMapping(value = "status/{appName}", method = RequestMethod.POST)
   	public ResultMap servStatus(@PathVariable String appName, String instanceId, String status){
   		log.info("appName:{} instanceId:{} status:{} defaultZone:{}",
   				new Object[] {appName, instanceId, status,defaultZone});
   
   		//拼凑url
   		String url= defaultZone;
   		String outOfServiceUrl = defaultZone + "apps/%s/%s/status?value=OUT_OF_SERVICE";
   		String upUrl = defaultZone + "apps/%s/%s/status?value=UP";
   
   		if(status.equalsIgnoreCase("UP")) {
   			//curl -v -X DELETE "127.0.0.1:9500/eureka/apps/CLIENT-A/192.168.1.101:client-a:7070/status?value=UP"
   			upUrl = String.format(upUrl, appName, instanceId);
   			HttpUtil.delete(upUrl, null, null, null, "UTF-8");
   		} else if(status.equalsIgnoreCase("OUT_OF_SERVICE")) {
   			outOfServiceUrl = String.format(outOfServiceUrl,appName,instanceId);
   			//curl -v -X PUT "127.0.0.1:9500/eureka/apps/CLIENT-A/192.168.1.101:client-a:7070/status?value=OUT_OF_SERVICE"
   			HttpUtil.put(outOfServiceUrl,null,null,null,"UTF-8");
   		}
   
   
   
   		return ResultMap.buildSuccess();
   	}

   倒不如用官方的rest API操作。
