这里我用了两个生产者和两个消费者进行演示,如下图(画的不好看,凑活看看):

这里我就只讲下怎么注册到dashbord和相关的配置,提供者和消费者等代码可以去下载查看:

1.hystrix的配置:

这里我将熔断器(或者称为断路器配置到了消费者端):

StuConsumerApplication:

package com.consumer.stuconsumer;

import org.springframework.boot.autoconfigure.SpringBootApplication;

import org.springframework.cloud.client.circuitbreaker.EnableCircuitBreaker;

import org.springframework.cloud.netflix.eureka.EnableEurekaClient;

@SpringBootApplication

@EnableEurekaClient

@EnableFeignClients

@EnableCircuitBreaker

public class StuConsumerApplication {

    public static void main(String[] args) {

        SpringApplication.run(StuConsumerApplication.class, args);

    }

}

import org.springframework.web.bind.annotation.GetMapping;

import org.springframework.web.bind.annotation.PathVariable;

@RestController

public class ConsumerController {

    public Student getAll(@PathVariable("id") Integer id) {

        Student stu = userFeignClient.getAll(id);

        return stu;

    }

}

Feign:(这个是配置断路器的主要配置)

ConsumerFeign:

StuDashbordApplication:

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.SpringBootApplication;

import org.springframework.cloud.netflix.hystrix.dashboard.EnableHystrixDashboard;

import org.springframework.cloud.netflix.turbine.EnableTurbine;

@SpringBootApplication

@EnableHystrixDashboard

public class StuDashbordApplication {

    public static void main(String[] args) {

        SpringApplication.run(StuDashbordApplication.class, args);

    }

}

application.yml:

server:

  port: 8030

3.启动dashbord并访问:http://localhost:8030/hystrix:

输入http://localhost:9301/hystrix.stream

然后 我们访问http://localhost:9301/getAll/1,可以在仪表盘中看到如下的信息:

这时,我们的dashbord单个应用监控完毕,但是我们在实际应用中往往不止用到一个应用,这时就需要我们来监控多个应用,这边我们可以配置turbine来进行应用的监控集群:

4.建立turbine

StuTurbineApplication:

import org.springframework.cloud.client.discovery.EnableDiscoveryClient;

import org.springframework.cloud.netflix.turbine.EnableTurbine;

@EnableTurbine

@EnableDiscoveryClient

@SpringBootApplication

public class StuTurbineApplication {

    public static void main(String[] args) {

        SpringApplication.run(StuTurbineApplication.class, args);

    }

}

application.yml(重点关注):

server:

  port: 8031

spring:

  application:

    name: stu-hystrix-turbine

eureka:

  client:

    serviceUrl:

      defaultZone: http://user:password123@localhost:8761/eureka

  instance:

    prefer-ip-address: true

turbine:

  aggregator:

    clusterConfig: default

  appConfig:  stu-consumer-feign-hytrix,stu-consumer

  clusterNameExpression: "'default'"

  instanceUrlSuffix: /hystrix.stream

#turbine.instanceUrlSuffix=/xxx/hystrix.stream

我们这边一定要配置 instanceUrlSuffix: /hystrix.stream,当然可以少一个/,这边不配置这个路径的话会报路径错误,这个是指定他路径后缀用的.

然后我们启动turbine,这时候我们在仪表盘再进行监控就可以看到多个应用的监控信息了:

配置监控的路径:http://localhost:8031/turbine.stream

仪表盘显示状态:
