SpringBoot2.0 ZipKin示例代碼

更新時間：2018年11月10日 15:53:05 作者：攻城遭雷劈

這篇文章主要介紹了SpringBoot2.0 ZipKin示例代碼，詳細的介紹了什么是ZipKin以及SpringBoot2.0 ZipKin示例，具有一定的參考價值，感興趣的小伙伴們可以參考一下

Zipkin是一種分布式跟蹤系統(tǒng)。它有助于收集解決微服務(wù)架構(gòu)中延遲問題所需的時序數(shù)據(jù)。它管理這些數(shù)據(jù)的收集和查找。Zipkin的設(shè)計基于 Google Dapper論文。

應(yīng)用程序用于向Zipkin報告時間數(shù)據(jù)。Zipkin用戶界面還提供了一個依賴關(guān)系圖，顯示每個應(yīng)用程序有多少跟蹤請求。如果您正在解決延遲問題或錯誤問題，則可以根據(jù)應(yīng)用程序，跟蹤長度，注釋或時間戳過濾或排序所有跟蹤。選擇跟蹤后，您可以看到每個跨度所需的總跟蹤時間百分比，從而可以識別問題應(yīng)用程序。

這是翻譯過來的原意，自己在這里想如果有個調(diào)用鏈，我們自己該怎么實現(xiàn)。要去質(zhì)疑任何代碼。

官方流程圖：最關(guān)鍵的是Transport這個地方，通過幾種方式傳輸給Conllector。如何在這里支持多種協(xié)議，有興趣的可以進去看看源碼。

開始示例，在這里通過一個項目調(diào)用不同的方法來進行測試。

先下載Zipkin的web UI，通過java -jar zipkin.jar執(zhí)行

項目結(jié)構(gòu)：
