使用JPA/Hibernate的

我已經成功地讓JPA/Hibernate的工作，按照基督教施耐德的教程： http://liquid-reality.de/display/liquid/2012/01/13/Apache+Karaf+Tutorial+Part+6+-+Database+Access 使用JPA/Hibernate的

但是，這涉及到創建命名等/ org.ops4j「文件。數據源 - tasklist.cfg有以下內容：」

osgi.jdbc.driver.name=H2-pool-xa 
url=jdbc:h2:mem:person 
dataSourceName=person

使用OSGi容器中運行PaxExam時，這顯然是行不通的。

另外，我寧願不在blueprint.xml或persistence.xml文件中添加環境特定的數據源參數，因爲隨後代碼會在代碼在不同的環境中運行時修改這些文件。

因此，在config（）方法或其他地方，必須有一種方法可以從JUnit/PaxExam調用的測試類中啓動數據源？

所以，問題是：

使用從基督教的教程（如了dataSourceName =人）在上述摘錄中定義的參數，我們怎麼會旋轉了一個新的數據源進行實例化OSGi容器內定義通過PaxExam？
這是否涉及對測試類的增強
或者在獨立文件中創建數據源定義然後添加到OSGI容器中會更好嗎？

一些項目的細節，我的測試類給出如下：

您可以使用與aries itests相同的方法。注入ConfigurationAdmin並在@Before方法中創建一個配置。
