如何從另一個模塊導入類maven

我不能從ejb模塊導入類到web模塊。 ejb類在包中：jsf在模塊ejb中，我想將其導入到Web模塊包中：jsf如何從另一個模塊導入類maven

import jsf.DaneOsobowe; - 劑量工作

我錯了什麼？

使用EJB作爲依賴是非常奇怪的。如果你的.war在某些庫中沒有.ejb的話，我不會感到驚訝。您應該將共享組件放入單獨的共享.jar庫中，並從.ejb和.war中引用它。 –

我該怎麼做？我是一個begginer我java – szkut

對不起，我不是很熟悉EAR + EJB的東西，因爲我遇到的大多數情況都是嚴重的併發症。然而，如果這就是你需要使用...

退房an answer explaining them in some detail。

基本上EJB應該包含一些在別處定義的接口的實現。 WAR不知道它在運行時會得到什麼樣的實現，它只知道接口，所以它應該取決於接口。讓我們把這些接口API，你會得到以下項目結構：

parent 
|- api 
|- ejb 
|- war 
\- ear

其中：

API只包含接口（不指定包裝，它會默認爲JAR）
EJB取決於API來實現一些/所有接口
WAR取決於API使用它們（例如，通過接口注入點）
EAR取決於WAR和EJB兩個捆綁成最終的歸檔文件

如果這對於您的用例來說太複雜了，那麼您可以從包含的所有內容開始，並且稍後重新構造一切。您可以將.war部署到任何應用程序服務器，甚至只是沒有完整應用程序服務器功能的容器。
