spring cloud(五) hystrix

开启feign 熔断 hystrix 整合hystrix-dashboard监控面板

1. 服务调用者boot工程 pom引入依赖

<!-- hystrix-dashboard 监控依赖 -->

        <dependency>

            <groupId>org.springframework.cloud</groupId>

            <artifactId>spring-cloud-starter-netflix-hystrix</artifactId>

            <version>2.0.2.RELEASE</version>

        </dependency>

        <dependency>

            <groupId>org.springframework.cloud</groupId>

            <artifactId>spring-cloud-starter-netflix-hystrix-dashboard</artifactId>

            <version>2.0.2.RELEASE</version>

        </dependency>

        <dependency>

            <groupId>org.springframework.boot</groupId>

            <artifactId>spring-boot-starter-actuator</artifactId>

        </dependency>

2. 启动类开启熔断注解 @EnableCircuitBreaker 面板监控注解 @EnableHystrixDashboard 添加面板servlet

@SpringBootApplication

@EnableEurekaClient

@EnableFeignClients

@EnableCircuitBreaker

@EnableHystrixDashboard

public class WebWapApplication {

    public static void main(String[] args) {

        SpringApplication.run(WebWapApplication.class, args);

    }

    @Bean

    @LoadBalanced

    RestTemplate restTemplate(){

        return new RestTemplate();

    }

    @Bean

    public ServletRegistrationBean getServlet(){

        HystrixMetricsStreamServlet streamServlet=new HystrixMetricsStreamServlet();

        ServletRegistrationBean registrationBean=new ServletRegistrationBean(streamServlet);

        registrationBean.setLoadOnStartup(1);

        registrationBean.addUrlMappings("/actuator/hystrix.stream");

        registrationBean.setName("HystrixMetricsStreamServlet");

        return registrationBean;

    }

}

3.修改配置文件开启feign熔断设置超时时间

feign.hystrix.enabled=true

hystrix.command.default.execution.isolation.thread.timeoutInMilliseconds=20000

4.浏览器查看面板监控 http://localhost:8080/hystrix

点击Monitor Stream 可查看请求成功次数超时次数等等

整合多个服务分布式监控使用 Turbine

1.新建boot工程引入依赖

 <!-- eureka客户端  -->

        <dependency>

            <groupId>org.springframework.cloud</groupId>

            <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>

        </dependency>

        <!-- hystrix 监控面板  -->

        <dependency>

            <groupId>org.springframework.cloud</groupId>

            <artifactId>spring-cloud-starter-netflix-hystrix-dashboard</artifactId>

        </dependency>

        <dependency>

            <groupId>org.springframework.cloud</groupId>

            <artifactId>spring-cloud-netflix-turbine</artifactId>

        </dependency>

2.启动类添加注解

@SpringBootApplication

@EnableEurekaClient

@EnableHystrixDashboard

@EnableTurbine

public class HystrixDashboardApplication {

    public static void main(String[] args) {

        SpringApplication.run(HystrixDashboardApplication.class, args);

    }

    @Bean

    @LoadBalanced

    RestTemplate restTemplate(){

        return new RestTemplate();

    }

    @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;

    }

}

3. 配置文件

server.port=9004

spring.application.name=hystrix-dashboard

#eureka

eureka.client.service-url.defaultZone=http://localhost:9001/eureka/

eureka.instance.prefer-ip-address=true

eureka.instance.instance-id=${spring.cloud.client.ip-address}:${server.port}

management.endpoints.web.exposure.include=hystrix.stream,health,info

#要监控的服务name

turbine.app-config=web-wap

turbine.cluster-name-expression=new String("default")

management.endpoint.health.show-details=always

management.health.redis.enabled=false

4.启动查看面板
