15、Feign整合断路器监控Hystrix Dashboard

2020-05-02 00:00:00 整合监控断路器

Ribbon可以整合整合断路器监控Hystrix Dashboard，Feign也不能少, 本篇讲解一下Feign如何整合断路器监控Hystrix Dashboard。本篇主要整合sc-eureka-client-consumer-feign-hystrix项目和sc-hystrix-dashboard项目。

1、新建项目sc-feign-hystrix-dashboard，对应的pom.xml文件如下

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

  <modelVersion>4.0.0</modelVersion>

 

  <groupId>spring-cloud</groupId>

  <artifactId>sc-feign-hystrix-dashboard</artifactId>

  <version>0.0.1-SNAPSHOT</version>

  <packaging>jar</packaging>

 

  <name>sc-feign-hystrix-dashboard</name>

  <url>http://maven.apache.org</url>

 

<parent>

<groupId>org.springframework.boot</groupId>

<artifactId>spring-boot-starter-parent</artifactId>

<version>2.0.4.RELEASE</version>

</parent>

 

<dependencyManagement>

<dependencies>

<dependency>

<groupId>org.springframework.cloud</groupId>

<artifactId>spring-cloud-dependencies</artifactId>

<version>Finchley.RELEASE</version>

<type>pom</type>

<scope>import</scope>

</dependency>

 

</dependencies>

</dependencyManagement>

 

<properties>

<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

<maven.compiler.source>1.8</maven.compiler.source>

<maven.compiler.target>1.8</maven.compiler.target>

</properties>

 

<dependencies>

 

<!-- 说明是一个 eureka client -->

<dependency>

<groupId>org.springframework.cloud</groupId>

<artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>

</dependency>

 

<dependency>

<groupId>org.springframework.boot</groupId>

<artifactId>spring-boot-starter-web</artifactId>

</dependency>

 

<!-- <dependency>

        <groupId>org.springframework.cloud</groupId>

        <artifactId>spring-cloud-starter-feign</artifactId>

    <version>1.4.5.RELEASE</version>

   </dependency> -->

 

<dependency>

<groupId>org.springframework.cloud</groupId>

<artifactId>spring-cloud-starter-openfeign</artifactId>

</dependency>

 

 

<!-- <dependency>

    <groupId>org.springframework.cloud</groupId>

    <artifactId>spring-cloud-starter-hystrix-dashboard</artifactId>

    <version>1.4.5.RELEASE</version>

</dependency> -->

 

 

<dependency>

    <groupId>org.springframework.cloud</groupId>

    <artifactId>spring-cloud-starter-netflix-hystrix-dashboard</artifactId>

</dependency>

 

 

<!-- <dependency>

    <groupId>org.springframework.cloud</groupId>

    <artifactId>spring-cloud-starter-hystrix</artifactId>

    <version>1.4.5.RELEASE</version>

</dependency> -->

 

<dependency>

    <groupId>org.springframework.cloud</groupId>

    <artifactId>spring-cloud-starter-netflix-hystrix</artifactId>

</dependency>

 

 

<dependency>

    <groupId>org.springframework.boot</groupId>

    <artifactId>spring-boot-starter-actuator</artifactId>

</dependency>

 

</dependencies>

</project>

说明：可以看出这个pom.xml文件是sc-eureka-client-consumer-feign-hystrix项目和sc-hystrix-dashboard项目的并集。

2、新建spring root 启动类FeignDashboardApplication.java

package sc.consumer;

 

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.SpringBootApplication;

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

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

import org.springframework.cloud.openfeign.EnableFeignClients;

 

@SpringBootApplication

@EnableEurekaClient

@EnableFeignClients

@EnableHystrixDashboard

public class FeignDashboardApplication {

 

public static void main(String[] args) {

SpringApplication.run(FeignDashboardApplication.class, args);

}

 

}
