休眠JPA事務運行TestCases時沒有激活錯誤，但在主類中執行時工作正常

我試圖通過EntityManager與Guice注入一起使用jpa持久性插入實體對象。它工作正常，當我試圖插入一個對象使用我的主要類的oject條目反映在我的數據庫。但是，當我執行我的Junit測試案例時，它顯示我錯誤：「java.lang.IllegalStateException：Transaction not active」，while db in db Remaining methods proplerly works。休眠JPA事務運行TestCases時沒有激活錯誤，但在主類中執行時工作正常

============== AbstractHibernateRepository<T> Class==================

Error while it throws while running testCases is

嘿柴塔尼亞它只顯示此消息，而執行測試用例 – 2014-09-30 15:32:13

嘿，我發現它是導入問題的錯誤。而不是使用javax.transaction.Transactional 的我使用com.google.inject.persist.Transactional

所以，當我們使用google.inject.persist.transaction那麼交易沒有active.Then它將通過異常時有人試圖提交或刷新任何交易。
