SpringCloud-Zipkin

Zipkin

Zipkin 是 Twitter 的一個開源項目，它基於 Google Dapper 實現，它致力於收集服務的定時數據，以解決微服務架構中的延遲問題，包括數據的收集、存儲、查找和展現。

   4 啓動類

   

package com.example.demo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
import zipkin2.server.internal.EnableZipkinServer;

@SpringBootApplication
@EnableDiscoveryClient
@EnableZipkinServer
public class DemoApplication {


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

}

運行結果

1運行 eurek   http://127.0.0.1:8187/

 

2 zipkinservice   url    http://127.0.0.1:9411/zipkin/

2 運行 新建服務提供-productservice      http://127.0.0.1:8102/hello

3 運行 服務調用-orderserverice   http://127.0.0.1:8111/product/hello

最後在刷新 zipkinservice 如果沒有出來數據 你可以重新 打開http://127.0.0.1:8111/product/hello  http://127.0.0.1:8111/product/hello

結果：
