    @EnableHystrixDashboard

    //Turbine

    @EnableTurbine

   

   

order 訂單服務

 

訪問地址：http://localhost:8081

 

 

1、bootstrap.properties

先於application.properties加載獲取配置信息

   

    default config-server

    spring.cloud.config.uri=http://localhost:8888

    spring.cloud.config.fail-fast=true

   

    配置動態刷新

    management.endpoints.web.exposure.include=refresh,health,info

 

 

2、application.properties   

    server.port=8081

    spring.application.name=order

   

    eureka

    eureka.client.serviceUrl.defaultZone= http://localhost:8761/eureka/

   

    zipkin 地址

    spring.zipkin.base-url=http://localhost:9411

    zipkin 採集百分比

    spring.sleuth.sampler.probability=1.0

   

    hystrix 熔斷開啓

    feign.hystrix.enabled=true

 

 

3、pom.xml

    <!--hystrix-->

    <dependency>

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

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

    </dependency>

    <dependency>

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

        <artifactId>spring-cloud-starter-openfeign</artifactId>

    </dependency>

    <!--config-->

    <dependency>

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

        <artifactId>spring-cloud-starter-config</artifactId>

    </dependency>

    <!--zipkin-->

    <dependency>

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

        <artifactId>spring-cloud-starter-zipkin</artifactId>

    </dependency>

    <!--eureka-client-->

    <dependency>

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

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

    </dependency>

   

4、註解開啓

 

    @EnableFeignClients

    @EnableCircuitBreaker

    @EnableEurekaClient

   

5、hystrix.stream

    @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;

         }

6、@RefreshScope 參數刷新

 

在使用參數的類上添加註解 @RefreshScope

@Value("${app}")獲取參數配置

 

7、Feign調用和熔斷配置

@FeignClient(value = "stock",fallback = StockServiceHystric.class)
