## 一、创建module-cloud-provider-hystrix-payment8002 ##

## 二、修改pom.xml ##

<dependencies>
            <dependency>
                <groupId>otc.orientsec</groupId>
                <artifactId>cloud-api-commons</artifactId>
                <version>1.0-SNAPSHOT</version>
            </dependency>
            <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>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-devtools</artifactId>
                <scope>runtime</scope>
                <optional>true</optional>
            </dependency>
            <dependency>
                <groupId>org.projectlombok</groupId>
                <artifactId>lombok</artifactId>
                <optional>true</optional>
            </dependency>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-test</artifactId>
            </dependency>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
            </dependency>
    
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-starter-netflix-hystrix</artifactId>
            </dependency>
        </dependencies>

## 三、修改application.yml ##

server:
      port: 8002
    
    spring:
      application:
        name: cloud-payment-hystrix-service
    
    eureka:
      client:
        #表示是否将自己注册进eurekaServer，默认为true
        register-with-eureka: true
        #是否从EurekaServer抓取已有的注册信息，默认为true，单节点无所谓，集群必须设置为true，才能配合ribbon使用负载均衡
        fetch-registry: true
        service-url:
          defaultZone: http://eureka7001.com:7001/eureka/
    
      instance:
        instance-id: payment-hystrix-8002
        prefer-ip-address: true

## 四、主启动类 ##

@SpringBootApplication
    @EnableDiscoveryClient
    public class HystrixPayment8002 {
        public static void main(String[] args)
        {
            SpringApplication.run(HystrixPayment8002.class,args);
        }
    }

## 五、业务类 ##

5.1 service

@Service
    public class HystrixPaymentService {
    
        public String paymentInfo_ok(Integer id)
        {
            return "线程池："+Thread.currentThread().getName()+"  paymentInfo_ok,id="+id+"\t"+"成功";
        }
    
        //模拟业务流程长，耗时长
        public String paymentInfo_timeout(Integer id)  {
            int time=5;
            try {
                TimeUnit.SECONDS.sleep(time);
            }catch (InterruptedException e)
            {
                e.printStackTrace();
            }
    
            return "线程池："+Thread.currentThread().getName()+"  paymentInfo_timeout,id="+id+"\t"+"超时";
        }
    }

5.2 controller

@RestController
    public class HystrixPaymentController {
        @Autowired
        private HystrixPaymentService hystrixPaymentService;
    
        @GetMapping("/payment/info/ok/{id}")
        public String paymentInfo_ok(@PathVariable("id") Integer id)
        {
            return hystrixPaymentService.paymentInfo_ok(id);
        }
    
        //模拟业务流程长，耗时长
        @GetMapping("/payment/info/timeout/{id}")
        public String paymentInfo_timeout(@PathVariable("id") Integer id)  {
            return hystrixPaymentService.paymentInfo_timeout(id);
        }
    }

## 六、测试 ##

两个服务都能正常应答，但timeout应答耗时5秒。
