常規+ JPA +行家=裝載機約束違規的javax/XML /變換/來源

Question

，如果我從一個Groovy腳本來創建一個JPA的EntityManager我得到這些錯誤：如果我從一個主創造了EntityManager

java.lang.LinkageError: loader constraint violation: loader (instance of <bootloader>) previously initiated loading for a different type with name "javax/xml/transform/Source" 
at javax.xml.validation.SchemaFactory.newSchema(SchemaFactory.java:594) 
at org.hibernate.ejb.packaging.PersistenceXmlLoader.loadURL(PersistenceXmlLoader.java:89) 
at org.hibernate.ejb.packaging.PersistenceXmlLoader.deploy(PersistenceXmlLoader.java:168) 
at org.hibernate.ejb.Ejb3Configuration.configure(Ejb3Configuration.java:310) 
at org.hibernate.ejb.HibernatePersistence.createEntityManagerFactory(HibernatePersistence.java:55) 
at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:48) 
... 

方法在Java類中它將工作。

我用MAVE，在我的POM的依賴關係是這樣的：

誰能告訴我什麼，我有做錯了，我該怎麼解決呢？

Answer 1

的javax.xml.transform.Source現在是JDK 6的一部分，似乎有些依賴（可能休眠）具有間接依賴於XML的API jar文件（這其實也包含java.xml。*類）。您必須找到該依賴關係並排除xml-apis。
