微服务之springCloud-docker-hystrix-dashboard-turbine（九）
简介
Hystrix的主要优点之一是它收集关于每个HystrixCommand的一套指标。Hystrix仪表板以有效的方式显示每个断路器的运行状况，通过Hystrix Dashboard我们可以在直观地看到各Hystrix Command的断路器是否打开，请求响应时间, 请求失败率，请求超时个数等等数据。但是只使用Hystrix Dashboard的话, 你只能看到单个应用内的服务信息, 这明显不够. 我们需要一个工具能让我们汇总系统内多个服务的数据并显示到Hystrix Dashboard上, 这个工具就是Turbine，这节我们讨论一下，怎么用turbine+hystrix-dashboard监听两个消费者服务
一、监听模块microservice-consumer-movie-feign-with-hystrix断路器的运行状况
这个模块在前面博客中讨论，这里就不写怎么创建了

二、监听模块microservice-consumer-movie-ribbon-with-hystrix1断路器的运行状况
2.1、创建模块microservice-consumer-movie-ribbon-with-hystrix1
项目结构如下：
2.2、pom.xml文件
<?xml version="1.0" encoding="UTF-8"?> <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"> <parent> <artifactId>microservice-spring-cloud</artifactId> <groupId>com.jacky</groupId> <version>1.0-SNAPSHOT</version> </parent> <modelVersion>4.0.0</modelVersion> <artifactId>microservice-consumer-movie-ribbon-with-hystrix1</artifactId> <packaging>jar</packaging> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> <java.version>1.8</java.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-eureka</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-actuator</artifactId> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-hystrix</artifactId> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-zipkin</artifactId> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>com.spotify</groupId> <artifactId>docker-maven-plugin</artifactId> <executions> <!--设置在执行maven 的install时构建镜像--> <execution> <id>build-image</id> <phase>install</phase> <goals> <goal>build</goal> </goals> </execution> </executions> <configuration> <!--安装了docker的主机，并且打开了api remote接口设置--> <dockerHost>http://192.168.6.130:5678</dockerHost> <pushImage>true</pushImage><!--设置上传镜像到私有仓库，需要docker设置指定私有仓库地址--> <!--镜像名称--> <imageName>${docker.repostory}/${docker.image.prefix}/${project.artifactId}:${project.version}</imageName> <!--镜像的基础版本--> <baseImage>java:openjdk-8-jdk-alpine</baseImage> <!--镜像启动参数--> <entryPoint>["java", "-jar", "/${project.build.finalName}.jar"]</entryPoint> <resources> <resource> <targetPath>/</targetPath> <directory>${project.build.directory}</directory> <include>${project.build.finalName}.jar</include> </resource> </resources> </configuration> </plugin> </plugins> </build> </project>
2.3、配置文件application.yml
spring:
application:
name: microservice-consumer-movie-ribbon-with-hystrix1

# user-info-uri: http://localhost:9999/uaa/user
#prefer-token-info: false
2.4、实体类User.java
package com.jacky.cloud.entity; import java.math.BigDecimal; public class User { private Long id; private String username; private String name; private Short age; private BigDecimal balance; public Long getId() { return this.id; } public void setId(Long id) { this.id = id; } public String getUsername() { return this.username; } public void setUsername(String username) { this.username = username; } public String getName() { return this.name; } public void setName(String name) { this.name = name; } public Short getAge() { return this.age; } public void setAge(Short age) { this.age = age; } public BigDecimal getBalance() { return this.balance; } public void setBalance(BigDecimal balance) { this.balance = balance; } }
2.5、控制层MovieController.java
package com.jacky.cloud.controller; import com.netflix.hystrix.contrib.javanica.annotation.HystrixProperty; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.PathVariable; import org.springframework.web.bind.annotation.RestController; import org.springframework.web.client.RestTemplate; import com.jacky.cloud.entity.User; import com.netflix.hystrix.contrib.javanica.annotation.HystrixCommand; @RestController public class MovieController { @Autowired private RestTemplate restTemplate; @GetMapping("/movie/{id}") @HystrixCommand(groupKey="UserGroup1", commandKey = "findUserByIdCommand1",commandProperties = { @HystrixProperty(name = "execution.isolation.thread.timeoutInMilliseconds", value = "1000"), @HystrixProperty(name = "execution.timeout.enabled", value = "false")},fallbackMethod = "findByIdFallback") public User findById(@PathVariable Long id) { return this.restTemplate.getForObject("http://microservice-provider-user/simple/" + id, User.class); } /** * fallback方法 * @param id * @return */ public User findByIdFallback(Long id) { User user = new User(); user.setId(5L); return user; } }
2.6、启动类
package com.jacky.cloud; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.cloud.client.circuitbreaker.EnableCircuitBreaker; import org.springframework.cloud.client.loadbalancer.LoadBalanced; import org.springframework.cloud.netflix.eureka.EnableEurekaClient; import org.springframework.context.annotation.Bean; import org.springframework.web.client.RestTemplate; @SpringBootApplication @EnableEurekaClient @EnableCircuitBreaker //映入断路器注解 public class ConsumerMovieRibbonApplication { @Bean @LoadBalanced public RestTemplate restTemplate() { return new RestTemplate(); } public static void main(String[] args) { SpringApplication.run(ConsumerMovieRibbonApplication.class, args); } }
三、创建hystrix+turbine模块（microservice-hystrix-turbine1）
项目结构如下：
3.1、pom.xml文件
<?xml version="1.0" encoding="UTF-8"?> <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"> <parent> <artifactId>microservice-spring-cloud</artifactId> <groupId>com.jacky</groupId> <version>1.0-SNAPSHOT</version> </parent> <modelVersion>4.0.0</modelVersion> <artifactId>microservice-hystrix-turbine1</artifactId> <packaging>jar</packaging> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> </properties> <dependencies> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-turbine</artifactId> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-netflix-turbine</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-actuator</artifactId> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-hystrix-dashboard</artifactId> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>com.spotify</groupId> <artifactId>docker-maven-plugin</artifactId> <executions> <!--设置在执行maven 的install时构建镜像--> <execution> <id>build-image</id> <phase>install</phase> <goals> <goal>build</goal> </goals> </execution> </executions> <configuration> <!--安装了docker的主机，并且打开了api remote接口设置--> <dockerHost>http://192.168.6.130:5678</dockerHost> <pushImage>true</pushImage><!--设置上传镜像到私有仓库，需要docker设置指定私有仓库地址--> <!--镜像名称--> <imageName>${docker.repostory}/${docker.image.prefix}/${project.artifactId}:${project.version}</imageName> <!--镜像的基础版本--> <baseImage>java:openjdk-8-jdk-alpine</baseImage> <!--镜像启动参数--> <entryPoint>["java", "-jar", "/${project.build.finalName}.jar"]</entryPoint> <resources> <resource> <targetPath>/</targetPath> <directory>${project.build.directory}</directory> <include>${project.build.finalName}.jar</include> </resource> </resources> </configuration> </plugin> </plugins> </build> </project>
3.2、配置文件application.yml
server: port: 8031 spring: application: name: microservice-hystrix-turbine eureka: client: serviceUrl: defaultZone: http://jacky:admin@peer1:8761/eureka/,http://jacky:admin@peer2:8762/eureka/,http://jacky:admin@peer3:8763/eureka/ instance: prefer-ip-address: true turbine: aggregator: clusterConfig: default #指定聚合哪些集群，多个使用”,”分割，默认为default。可使用http://.../turbine.stream?cluster={clusterConfig之一}访问 #配置Eureka中的serviceId列表，表明监控哪些服务 appConfig: microservice-consumer-movie-feign-with-hystrix,microservice-consumer-movie-ribbon-with-hystrix1 #1. clusterNameExpression指定集群名称，默认表达式appName；此时：turbine.aggregator.clusterConfig需要配置想要监控的应用名称； #2. 当clusterNameExpression: default时，turbine.aggregator.clusterConfig可以不写，因为默认就是default； #3. 当clusterNameExpression: metadata[‘cluster’]时，假设想要监控的应用配置了eureka.instance.metadata-map.cluster: ABC，则需要配置，同时turbine.aggregator.clusterConfig: ABC clusterNameExpression: "'default'"
3.3、启动类
package com.jacky.cloud; 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; @EnableTurbine @EnableHystrixDashboard @SpringBootApplication public class TurbineApplication { public static void main(String[] args) { SpringApplication.run(TurbineApplication.class, args); } }
四、启动
- 启动 microservice-provider-user
- 启动 microservice-consumer-movie-feign-with-hystrix
- 启动microservice-consumer-movie-ribbon-with-hystrix1
- 启动microservice-hystrix-turbine
五、测试
