## springcloud zipkin环境搭建 ##

#### 一、环境安装 ####

下载一个zipkin的jar包，直接cmd运行即可，浏览器访问9411端口web管理页面。

## 二、模拟链路调用 ##

支付项目下订单需要调用调用订单接口，同时订单接口需要调用会员项目获取会员信息。  
即调用链如下：  
app-itmayiedu-pay ----> app-itmayiedu-order ----> app-itmayiedu-member

这三个都需要注册到eureka注册中心 运行端口8100

支付项目pom.xml

application.yml

###会员服务启动端口号
    server:
      port: 8060
    ###服务名称(服务注册到eureka名称)  
    spring:
        application:
            name: app-itmayiedu-pay
        zipkin:
            base-url: http://localhost:9411
        sleuth:
          sampler: 
              probability: 1 #样本采集量，默认为0.1，为了测试这里修改为1，正式环境一般使用默认值
    ###服务注册到eureka地址
    eureka:
      client:
        service-url:
               defaultZone: http://localhost:8100/eureka

为了简单，启动类和控制器为同一个，项目上更需要分开

@SpringBootApplication
    @RestController
    @EnableEurekaClient
    public class PayController {
    	@Autowired
    	private RestTemplate restTemplate;
    
    	@RequestMapping("/payOrder")
    	public String payOrder() {
    		String orderUrl = "http://app-itmayiedu-order/orderToMember";
    		String reuslt = restTemplate.getForObject(orderUrl, String.class);
    		return reuslt;
    	}
    
    	@Bean
    	@LoadBalanced
    	RestTemplate restTemplate() {
    		return new RestTemplate();
    	}
    
    	public static void main(String[] args) {
    		SpringApplication.run(PayController.class, args);
    	}
    }

订单项目和会员服务pom文件一样，application.yml也几乎一样，端口改下，应用名称改下  
订单项目启动类

@SpringBootApplication
    @EnableEurekaClient
    @RestController
    public class EurekaOrderController {
    	@Autowired
    	private RestTemplate restTemplate;
    
    	// springcloud 中使用那些技术实现调用服务接口 feign 或者rest
    	@RequestMapping("/orderToMember")
    	public String orderToMember() {
    		String memberUrl = "http://app-itmayiedu-member/getMember";
    		return restTemplate.getForObject(memberUrl, String.class);
    	}
    
    
    	// 默认rest方式开启 负载均衡功能 如果以app-itmayiedu-member名称进行调用服务接口的时候 必须
    	@Bean
    	@LoadBalanced
    	RestTemplate restTemplate() {
    		return new RestTemplate();
    	}
    
    	public static void main(String[] args) {
    		SpringApplication.run(EurekaOrderController.class, args);
    	}
    
    }

调用链路和耗时以界面的形式显示出来。
