SpringCloud-hystrix-dashboard实战01

服务监控

端口修改

server.port=19000

pom依赖：

<!-- https://mvnrepository.com/artifact/org.springframework.cloud/spring-cloud-starter-netflix-hystrix-dashboard -->
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-netflix-hystrix-dashboard</artifactId>
    <version>2.1.2.RELEASE</version>
</dependency>
<!-- https://mvnrepository.com/artifact/org.springframework.cloud/spring-cloud-starter-netflix-hystrix -->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-hystrix</artifactId>
            <version>2.1.2.RELEASE</version>
        </dependency>

启动类中增加#EnableHystrixDashboard注解

@SpringBootApplication(exclude= {DataSourceAutoConfiguration.class})
@EnableHystrixDashboard
public class ApplicationConsumerhystrixDashboard {
    private static Logger logger = Logger.getLogger(ApplicationConsumerhystrixDashboard.class);

    /**
     * Start
     */
    public static void main(String[] args) {
        SpringApplication.run(ApplicationConsumerhystrixDashboard.class, args);
//        logger.info("SpringBoot Start Success");
    }
}

检查服务提供者是否增加了监控依赖

<!--actuator监控信息完善-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>

服务提供者中添加监控依赖

验证服务启动ok

启动eureka集群

eureka集群

启动一个服务提供者

证明服务提供者启动ok

服务提供项目启动之后访问不到http://localhost:18084/hystrix.stream，添加以下配置及bean

#application.properties中
management.endpoints.web.exposure.include="*"
#启动类中注入bean
    @Bean
    public ServletRegistrationBean hystrixMetricsStreamServlet() {
        ServletRegistrationBean registration = new ServletRegistrationBean(new HystrixMetricsStreamServlet());
        registration.addUrlMappings("/hystrix.stream");
        return registration;
    }
