Dashboard监控一直是Loading ping:一直都是空的

在我配置好了pom.xml和启动类注解以后发现ping:一直都是空的 即使根据网上的方法访问了以后刷新也还是空的 但是用下面的代码是可以监控到数据的

@RequestMapping(value = "/dept/get/{id}", method = RequestMethod.GET)
	//一旦调用服务方法失败并抛出了错误信息后，会自动调用@HystrixCommand标注好的fallbackMethod调用类中的指定方法
	@HystrixCommand(fallbackMethod = "processHystrix_Get")
	public Dept get(@PathVariable("id") Long id)
	{

		Dept dept = this.service.get(id);
		
		if (null == dept) {
			throw new RuntimeException("该ID：" + id + "没有没有对应的信息");
		}
		
		return dept;
	}

	public Dept processHystrix_Get(@PathVariable("id") Long id)
	{
		return new Dept().setDeptno(id).setDname("该ID：" + id + "没有没有对应的信息,[e-mail]")
				.setDb_source("no this database in MySQL");
	}

直到我用了FallbackFactory之后去除了该方法上的@HystrixCommand注解 发现Dashboard监控不到数据，于是对代码进行了如下修改

package com.kelestar.springcloud.controller;
import com.kelestar.springcloud.entities.Dept;
import com.kelestar.springcloud.service.DeptService;
import com.netflix.hystrix.contrib.javanica.annotation.HystrixCommand;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.cloud.client.ServiceInstance;
import org.springframework.cloud.client.discovery.DiscoveryClient;
import org.springframework.web.bind.annotation.*;

import java.util.List;

@RestController
public class DeptController {
    @Autowired
    private DeptService service;
    @Autowired
    private DiscoveryClient client;
    @HystrixCommand
    @PostMapping(value = "/dept/add")
    public boolean add(@RequestBody Dept dept){
        System.out.println(dept.toString());
        return service.add(dept);
    }
    @HystrixCommand
    @GetMapping(value = "/dept/get/{id}")
    public Dept get(@PathVariable("id") Long id){
        return service.get(id);
    }
    @HystrixCommand
    @GetMapping(value = "dept/list")
    public List<Dept> list(){
        return service.list();
    }
    @HystrixCommand
    @RequestMapping(value = "/dept/discovery", method = RequestMethod.GET)
    public Object discovery()
    {
        List<String> list = client.getServices();
        System.out.println("**********" + list);

        List<ServiceInstance> srvList = client.getInstances("SERVICECLOUD-DEPT");
        for (ServiceInstance element : srvList) {
            System.out.println(element.getServiceId() + "\t" + element.getHost() + "\t" + element.getPort() + "\t"
                    + element.getUri());
        }
        return this.client;
    }
}

若想监控某个请求只需要在方法上添加@HystrixCommand注解即可 不添加该注解的方法在Dashboard上是监控不到的
