命名Hibernate查询的“命名查询未知”？

可能是什么问题？

@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：

不确定这是否是您的问题，但请查看此post。

问题是使用：

 org.hibernate.annotations.Entity 

代替：

 javax.persistence.Entity
