SpringCloud之Dashboard 流监控

SpringCloud之Dashboard 流监控

新建springcloud-consumer-hystrix-dashboard模块

添加依赖

<!--Hystrix依赖-->
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-hystrix</artifactId>
    <version>1.4.6.RELEASE</version>

<!--dashboard依赖 旧版 建议用下面一个-->
<!--<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-hystrix-dashboard</artifactId>
    <version>1.4.6.RELEASE</version>

主启动类

@SpringBootApplication
// 开启Dashboard
@EnableHystrixDashboard
public class DeptConsumerDashboard_9001 {
    
    
    public static void main(String[] args) {
    
    
        SpringApplication.run(DeptConsumerDashboard_9001.class,args);
    }
}

给springcloud-provider-dept-hystrix-8001(看之前的文章)模块下的主启动类添加如下代码,添加监控

@SpringBootApplication
@EnableEurekaClient //EnableEurekaClient 客户端的启动类，在服务启动后自动向注册中心注册服务
public class DeptProvider_8001 {
    
    
    public static void main(String[] args) {
    
    
        SpringApplication.run(DeptProvider_8001.class,args);
    }

    //增加一个 Servlet
    @Bean
    public ServletRegistrationBean hystrixMetricsStreamServlet(){
    
    
        ServletRegistrationBean registrationBean = new ServletRegistrationBean(new HystrixMetricsStreamServlet());
        //访问该页面就是监控页面
        registrationBean.addUrlMappings("/actuator/hystrix.stream");
       
        return registrationBean;
    }
}

访问：http://localhost:9001/hystrix

进入监控页面：

注意：输对网址，不然会报错

注意：如果出现一直加载中，可能是版本SpringCloud太高了或者监控的版本不匹配，js加载显示304

效果如下图：
