Spring Cloud中如何断路器聚合监控,很多新手对此不是很清楚,为了帮助大家解决这个难题,下面小编将为大家详细讲解,有这方面需求的人可以来学习下,希望你能有所收获。
一、准备工作
把以前的项目 service-feign 进行同样的改造。
二、新建maven项目service_turbine
1、新建pom.xml
<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>wg</groupId> <artifactId>service_turbine</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>jar</packaging> <name>service_turbine</name> <url>http://maven.apache.org</url> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> <spring-cloud.version>Greenwich.RELEASE</spring-cloud.version> <java.version>1.8</java.version> </properties> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.1.1.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-actuator</artifactId> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-netflix-hystrix</artifactId> </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-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-openfeign</artifactId> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-netflix-turbine</artifactId> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <scope>test</scope> </dependency> </dependencies> <dependencyManagement> <dependencies> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-dependencies</artifactId> <version>${spring-cloud.version}</version> <type>pom</type> <scope>import</scope> </dependency> </dependencies> </dependencyManagement> </project>
2、新建ServiceTurbineApplication.java
package wg; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.cloud.client.circuitbreaker.EnableCircuitBreaker; import org.springframework.cloud.client.discovery.EnableDiscoveryClient; import org.springframework.cloud.netflix.eureka.EnableEurekaClient; import org.springframework.cloud.netflix.hystrix.EnableHystrix; import org.springframework.cloud.netflix.hystrix.dashboard.EnableHystrixDashboard; import org.springframework.cloud.netflix.turbine.EnableTurbine; import org.springframework.cloud.openfeign.EnableFeignClients; @SpringBootApplication @EnableEurekaClient @EnableDiscoveryClient @EnableFeignClients @EnableHystrix @EnableHystrixDashboard @EnableCircuitBreaker @EnableTurbine public class ServiceTurbineApplication { public static void main(String[] args) { SpringApplication.run( ServiceTurbineApplication.class, args ); } }
3、新建application.yml
server: port: 8767 spring: application: name: service-turbine eureka: client: serviceUrl: defaultZone: http://localhost1:8761/eureka/,http://localhost2:8861/eureka/ management: endpoints: web: exposure: include: "*" cors: allowed-origins: "*" allowed-methods: "*" turbine: app-config: service-feign,service-ribbon aggregator: clusterConfig: default clusterNameExpression: new String("default") combine-host: true instanceUrlSuffix: default: actuator/hystrix.stream
4、启动项目,访问:http://localhost:8767/turbine.stream
5、访问:http://localhost:8764/hystrix ,填写内容
6、点击监控,然后访问:http://localhost:8765/hello,http://localhost:8764/hello
