如果我一起運行所有（31）單元測試，則在2 - 3個單元測試中出現以下連接錯誤，但是如果我單獨運行這些測試，那麼運行會成功。你能指導我這種奇怪的行爲嗎？我使用Spring 3.0.6，Spring批處理2.1.7和Oracle XE數據庫。下面Spring批處理 - 在某些單元測試中拒絕連接
是錯誤

這些測試是平行運行還是一個接一個運行？ – Ralph 2012-02-01 06:12:38
一個接一個。我認爲這就是maven和eclipse如何逐一運行它們。 – amique 2012-02-01 21:10:11
我比較喜歡：在下一次開始之前，所有附加的threds startet在一次測試中都會完成。 – Ralph 2012-02-02 06:59:52
