Dubbo分佈式服務框架入門實戰

首先，有必要清楚Dubbo是什麼。官方文檔的定義如下：

DUBBO是一個分佈式服務框架，致力於提供高性能和透明化的RPC遠程服務調用方案，是阿里巴巴SOA服務化治理方案的核心框架，每天爲2,000+個服務提供3,000,000,000+次訪問量支持，並被廣泛應用於阿里巴巴集團的各成員站點。

其實，總結起來就是：

Dubbo是一個解決大規模服務治理的高性能分佈式服務框架。

dubbo的架構如下：

節點角色說明：

Provider: 暴露服務的服務提供方。
Consumer: 調用遠程服務的服務消費方。
Registry: 服務註冊與發現的註冊中心。
Monitor: 統計服務的調用次調和調用時間的監控中心。
Container: 服務運行容器。

調用關係說明：

服務容器負責啓動，加載，運行服務提供者。
服務提供者在啓動時，向註冊中心註冊自己提供的服務。
服務消費者在啓動時，向註冊中心訂閱自己所需的服務。
註冊中心返回服務提供者地址列表給消費者，如果有變更，註冊中心將基於長連接推送變更數據給消費者。
服務消費者，從提供者地址列表中，基於軟負載均衡算法，選一臺提供者進行調用，如果調用失敗，再選另一臺調用。
服務消費者和提供者，在內存中累計調用次數和調用時間，定時每分鐘發送一次統計數據到監控中心。

Dubbo入門實戰

要完成一個dubbo的demo，其實只需要上面的Provider、Consumer和Registry。其中Registry使用Zookeeper來承擔，當提供者提供服務後，需要向Zookeeper（註冊中心）暴露其發佈的服務，消費者通過Zookeeper訂閱其需要消費的服務，然後就可以像調用本地服務一樣調用遠程服務了。

下面就需要編寫測試類來驗證服務提供者是否發佈成功，由於使用了Zookeeper作爲服務註冊中心，所以在運行測試代碼之前，需要首先啓動Zookeeper。具體Zookeeper的使用與配置請參考Zookeeper入門實戰。

測試代碼：

如果服務發佈成功，則會在控制檯打印出“服務提供者已註冊成功！”的提示。
