这是我的persistence.xml文件：

    java:/comp/env/jdbc/CounterpartContact com.counterpartcontacts.entity.AgentContact com.counterpartcontacts.entity.SecurityContact com.counterpartcontacts.entity.Bank      

这是我的persistenceLayer.xml：

      <!--  -->            

persistence.xml位于构建路径中的src / META-INF中，因此应该正确找到它。 有人有主意吗？

Answer 1

好吧，我通常将persistence.xml放在资源文件夹/src/main/resouces/META-INF/persistence.xml中，因为我确实记得构建中没有将资源复制到output-directory的问题。

我只是看看我们的配置，它看起来有点不同：

          classpath*:META-INF/persistence.xml                        ${cweb.database.dialect} ${cweb.database.generate} ${cwb.home}/indexes de.cware.cweb.jpa.QuotingNamingStrategy                     

希望这可以帮助 ：-）

Answer 2

• 将您的persistence.xml保存在WEB-INF / classes / META-INF / persistence.xml中

• 删除hibernate冲突的库….

• 如果hibernate核心存在，删除hibernate – 3.2.0 jar

Answer 3

将persistence.xml放在资源文件夹/src/main/resouces/META-INF/persistence.xml对我来说这是解决方案

Answer 4

如果你有一个与另一个非映射类关系的hibernate映射类，可能会发生这种错误，解决方法是将关系项检查为@transient（hibernate将忽略它，使用它来检查这是否是错误，以后映射相关的类）。 例：

 @Entity public class City { @Id @GeneratedValue(strategy=GenerationType.AUTO) private int id; private String name; @Transient private State state; public int getId() { return id; } public void setId(int id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } public State getState() { return state; } public void setState(State state) { this.state = state; } } 

这是可能给出错误的非映射类：

 public class State { private String name; }
