Hystrix的仪表盘配置

先配置仪表盘项目 ，9001端口

pom

<?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>cloud2020</artifactId> <groupId>com.atguigu.springcloud</groupId> <version>1.0-SNAPSHOT</version> </parent> <modelVersion>4.0.0</modelVersion> <artifactId>cloud-consumer-hystrix-dashboard9001</artifactId> <dependencies> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-netflix-hystrix-dashboard</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-actuator</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-devtools</artifactId> <scope>runtime</scope> <optional>true</optional> </dependency> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <optional>true</optional> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> </dependencies> </project>

application.yml

server: port: 9001

启动类

@SpringBootApplication @EnableHystrixDashboard public class HystrixDashboardMain9001 { public static void main(String[] args) { SpringApplication.run(HystrixDashboardMain9001.class, args); } }

 

注意这里是监控8001的熔断。

pom里一定要有

<!--web--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-actuator</artifactId> </dependency>

 

然后是修改下8001的启动类。一定要加bean，不然会连接不到。

Unable to connect to Command Metric Stream

@SpringBootApplication @EnableEurekaClient @EnableCircuitBreaker public class PaymentHystrixMain8001 { public static void main(String[] args) { SpringApplication.run(PaymentHystrixMain8001.class,args); } /** *此配置是为了服务监控而配置，与服务容错本身无关，springcloud升级后的坑 *ServletRegistrationBean因为springboot的默认路径不是"/hystrix.stream"， *只要在自己的项目里配置上下面的servlet就可以了 */ @Bean public ServletRegistrationBean getServlet() { HystrixMetricsStreamServlet streamServlet = new HystrixMetricsStreamServlet(); ServletRegistrationBean registrationBean = new ServletRegistrationBean(streamServlet); registrationBean.setLoadOnStartup(1); registrationBean.addUrlMappings("/hystrix.stream"); registrationBean.setName("HystrixMetricsStreamServlet"); return registrationBean; } }

 

看下9001的效果图，以及接下来要填写的内容，url是http://localhost:9001/hystrix

 

这里是closed，熔断关闭，代表健康
