# springcloud
基于springcloud、fegin、zipkin实现的一个服务注册、发现、服务链路追踪的例子

bizService：服务提供者

ConsumerService：服务消费者

springCloudEureka：服务注册中心

zipkinServer：服务链路追踪

详细说明：


	* 一、服务注册中心

1.pom.xml

```
<dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-eureka-server</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
</dependencies>
```

2.Application

```
@SpringBootApplication
@EnableEurekaServer
//@EnableDiscoveryClient
/**
* 服务注册发现中心
*/
public class SpringCloudEurekaApplication {

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

3.application.properties

```
server.port=8000
eureka.client.register-with-eureka=false
eureka.client.fetch-registry=false
spring.application.name=eureka-serve
eureka.client.serviceUrl.defaultZone=http://localhost:${server.port}/eureka/

```


	* 二、服务提供

1.pom.xml

```
<dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-eureka</artifactId>
</dependency>

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
</dependencies>
```

2.Application

```
/**
* 服务提供
*/
@SpringBootApplication
//启用服务注册与发现
@EnableDiscoveryClient
//启用feign进行远程调用
@EnableFeignClients
public class BizServiceApplication {

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

3.application.properties

```
spring.application.name=spring-cloud-producer
server.port=8001
eureka.client.serviceUrl.defaultZone=http://localhost:8000/eureka/
```

4.定义服务提供Controller

```
@RestController
public class HelloController {
@RequestMapping("/hello")
public String index(@RequestParam String name) {
return "hello " + name + "，this is first messge";
}
}
```



	* 三、服务调用

1.pom.xml

```
<dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-eureka</artifactId>
</dependency>

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-feign</artifactId>
</dependency>
</dependencies>
```

2.Application

```
@SpringBootApplication
@EnableDiscoveryClient
@EnableFeignClients
public class ConsumerServiceApplication {

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

3.application.properties

```
spring.application.name=spring-cloud-consumer
server.port=9001
eureka.client.serviceUrl.defaultZone=http://localhost:8000/eureka/
```

4.定义远程调用服务接口

```
@FeignClient(name= "spring-cloud-producer")
@Component
public interface HelloRemote {
@RequestMapping(value = "/hello")
String hello(@RequestParam(value = "name") String name);
}
```

5.Controller

```
@RestController
public class ConsumerController {
@Autowired
private HelloRemote helloRemote;
@RequestMapping("/hello/{name}")
public String index(@PathVariable("name") String name) {
return helloRemote.hello(name);
}
}
```


	* 四、服务链路追踪

服务提供者和消费者配置

1、pom.xml

```
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-zipkin</artifactId>
</dependency>
```

2、在application.properties追加下面配置

```
#配置zipKin Server的地址
spring.zipkin.base-url=http://127.0.0.1:9411
```
