篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了feign中的hytrix和turbin配置相关的知识，希望对你有一定的参考价值。

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.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.circuitbreaker.EnableCircuitBreaker;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
import org.springframework.cloud.netflix.feign.EnableFeignClients;

@SpringBootApplication
@EnableEurekaClient
@EnableFeignClients
@EnableCircuitBreaker
public class StuConsumerApplication {

    public static void main(String[] args) {
        SpringApplication.run(StuConsumerApplication.class, args);
    }
}

控制层:

import com.consumer.stuconsumer.entity.Student;
import com.consumer.stuconsumer.feign.UserFeignClient;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import javax.annotation.Resource;

@RestController
public class ConsumerController {
    @Resource
    private UserFeignClient userFeignClient;
    @RequestMapping("/getAll/{id}")
    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:

import com.consumer.stuconsumer.entity.Student;
import com.consumer.stuconsumer.feign.fallbackfactory.UserFallbackFactory;
import org.springframework.cloud.netflix.feign.FeignClient;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

//使用FeignClient 告知发布方的应用名称 默认使用ribbon进行负载均衡
@FeignClient(name = "stu-provide",fallbackFactory = UserFallbackFactory.class)
public interface ConsumerFeign {
    @RequestMapping(value = "/getAll/{id}",method = RequestMethod.GET)
    public Student getAll(@PathVariable("id") Integer id);

}

UserFeignWithFactory:

import com.consumer.stuconsumer.feign.ConsumerFeign;
//这个是hystrix的类
public interface UserFeignWithFactory extends ConsumerFeign {

}

UserFallbackFactory:

import com.consumer.stuconsumer.entity.Student;
import com.consumer.stuconsumer.feign.ConsumerFeign;
import com.consumer.stuconsumer.feign.feignclientwithfactory.UserFeignWithFactory;
import feign.hystrix.FallbackFactory;
import org.springframework.stereotype.Component;
//断路器设置
//这个是hystrix的类
@Component
public class UserFallbackFactory implements FallbackFactory<ConsumerFeign> {
    @Override
    public ConsumerFeign create(Throwable throwable) {
        return new UserFeignWithFactory(){
            @Override
            public Student getAll(Integer id) {
                return null;
            }
        };
    }
}

2.建立dashbord

</project>

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.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
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:[email protected]: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
