我正在編寫一個獨立的java應用程序,從Maven項目構建它並通過調用jar文件執行。持久性單元被覆蓋

在我有使用持久性單元,在我的persistence.xml定義是獨立的(交易類型=「RESOURCE_LOCAL」)

實際實體註解的類的實體管理應用來自另一個項目,並且因此作爲依賴項添加到pom.xml文件中。

問題是,包含實體類的項目的persistence.xml會在生成jar包的目標文件夾時覆蓋實際的獨立應用程序的persistence.xml。

Maven構建過程中經歷成功,但在運行罐子時,我得到這樣一個例外:

異常線程「main」 javax.persistence.PersistenceException:沒有 持久性提供適用於「PersistenceUnitXXX」試圖 後以下發現實現: org.eclipse.persistence.jpa.PersistenceProvider

另外包含實體類項目的持久性單元是指FO部署在應用程序服務器上,所以我認爲不可能爲獨立應用程序重複使用persistence.xml。

聚甲醛是這樣的:

用pom文件和文件結構更新。 –
