使用Apache Camel和Restlet獲取API

我正在做一個非常簡單的Fuse集成應用程序，它從API網站（Stockholms Stad的數據門戶）獲取XML。我正在使用Apache Camel將「url」中的「url」從「」路由到「新」word doc文件中。 2檔我這裏是Spring XML camel.context.xml文件和pom.xml的依賴關係：使用Apache Camel和Restlet獲取API

我跑的「的jboss-保險絲進行項目JBoss Developer Studio 10.1.0 GA上的6.3.0.redhat-187「Runtime Server。我啓動服務器，但沒有創建文件。它不起作用，我認爲它在代碼中有一些錯誤的語法。

如果您想調用外部現有REST服務，則需要從計時器開始。

from timer 
    to restlet 
    to file

你

from restlet

做什麼，如果你自己主持一個新的REST服務的目的。

隨着定時器，你需要找出你想調用現有的REST服務的頻率。計時器有可供您配置的選項。

哦，我明白了。所以我所理解的是調用外部REST Web服務需要一個定時器來開始連接，監聽或輪詢正確嗎？ – teowey

是的，如果你正在使用駱駝路線。如果您想從Java代碼調用任何Camel端點，則可以使用ProducerTemplate（作爲客戶端API）。然而駱駝路線經常與駱駝一起使用 –

ProducerTemplate文檔說它允許端點之間的消息交換。我對消息的概念很陌生。這是否意味着，如果我編寫Java代碼，我將不得不在我調用的API和本地主機端點之間實現消息交換？這是否需要，以便我可以生成我想要的新詞doc文件？ – teowey
