有什么问题吗？

@Entity
@NamedQueries( {
    @NamedQuery(name = User.ALL,
                query = "SELECT u FROM User u")
})

public class User {
    public static final String ALL = "User.all";
}

public class Service {
    find... with ... User.ALL
}

堆栈跟踪：

不知道这是否是你的问题，但看看这篇文章here。
问题是使用：

org.hibernate.annotations.Entity

而不是：

javax.persistence.Entity

当我在包中重命名一个Entity类时，我也遇到了类似的问题。确保persistence.xml中持久性单元的完整类名与Entity类匹配。例如

<persistence-unit name="your_PU_name" transaction-type="JTA">
      ...
      <class> [ make sure here is the FQN of your entity class ] </class>
      ...
   </persistence-unit>
