application.yml
server:
port: 9001
啓動類
@SpringBootApplication
@EnableHystrixDashboard
public class HystrixDashboardMain9001
{
public static void main(String[] args) {
SpringApplication.run(HystrixDashboardMain9001.class, args);
}
}
注意這裏是監控8001的熔斷。
pom裏一定要有
<!--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>
然後是修改下8001的啓動類。一定要加bean,不然會連接不到。
Unable to connect to Command Metric Stream
@SpringBootApplication
@EnableEurekaClient
@EnableCircuitBreaker
public class PaymentHystrixMain8001 {
public static void main(String[] args) {
SpringApplication.run(PaymentHystrixMain8001.class,args);
}
/**
*此配置是爲了服務監控而配置,與服務容錯本身無關,springcloud升級後的坑
*ServletRegistrationBean因爲springboot的默認路徑不是"/hystrix.stream",
*只要在自己的項目裏配置上下面的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的效果圖,以及接下來要填寫的內容,url是http://localhost:9001/hystrix
這裏是closed,熔斷關閉,代表健康
