springdashboard环境搭建

SpringCloud Hystrix Dashboard

Hystrix-dashboard是一款针对Hystrix进行实时监控的工具，通过Hystrix Dashboard我们可以在直观地看到各Hystrix Command的请求响应时间, 请求成功率等数据。

监控服务pom配置文件

       <!--系统注册与监控服务-->
       <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
        </dependency>
        <!--hystrix仪表盘-->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-hystrix-dashboard</artifactId>
        </dependency>

　　application.properties

server.port=8070
spring.application.name=claimdashboard

eureka.client.service-url.defaultZone=http://localhost:8091/eureka/
eureka.client.registerWithEureka=true
eureka.client.fetchRegistry=true

@SpringBootApplication
@EnableHystrixDashboard
public class ClaimdashboardApplication {
    /*
    启动输入http://localhost:8070/hystrix
    再输入某个需要监控的服务 http://localhost:8030/hystrix.stream
     */

    public static void main(String[] args) {
        SpringApplication.run(ClaimdashboardApplication.class, args);
    }
}

被监控服务的配置

        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-hystrix</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>

#服务名称
spring.application.name=claimaudit
#配置服务中心注册地址
eureka.client.service-url.defaultZone=http://localhost:8091/eureka/
eureka.client.instance.lease-renewal-interval-in-seconds=30
feign.hystrix.enabled=true

@SpringBootApplication
@EnableDiscoveryClient  //注册服务
@EnableFeignClients     //开启feign
@EnableHystrix //开启断路器
@EnableCircuitBreaker
public class ClaimauditApplication {
    public static void main(String[] args) {
        SpringApplication.run(ClaimauditApplication.class, args);

    }
}

主要是下面这段代码，如果不添加监控服务会报连接不上的错误

@Configuration
public class HystrixConfig {

    @Bean
    public HystrixMetricsStreamServlet hystrixMetricsStreamServlet(){
        return new HystrixMetricsStreamServlet();
    }

    @Bean
    public ServletRegistrationBean registration(HystrixMetricsStreamServlet servlet){
        ServletRegistrationBean registrationBean = new ServletRegistrationBean();
        registrationBean.setServlet(servlet);
        //是否启用该registrationBean
        registrationBean.setEnabled(true);
        registrationBean.addUrlMappings("/hystrix.stream");
        return registrationBean;
    }
}
