Org. hibernate. mappingexception: unknown entity

Org. hibernate. mappingexception: unknown entity does not find a solution suitable for me after searching for Baidu and googl for a long time. Finally, it is caused by the import entity class (this package is automatically prompted to be imported using eclipse)

Package com. tgx. model;

Import javax. Persistence. generatedvalue;
Import javax. Persistence. ID;

Import org. hibernate. Annotations. entity; // The error is introduced here...

@ Entity
Public class user {

Private int ID;
Private string username;


@ ID
@ Generatedvalue
Public int GETID (){
Return ID;
}

The introduced entity is modified later.

Package com. tgx. model;

Import javax. Persistence. entity; // This is correct.
Import javax. Persistence. generatedvalue;
Import javax. Persistence. ID;

@ Entity
Public class user {

Private int ID;
Private string username;

In addition, some reports org. hibernate. mappingexception: unknown entity, which may be caused by not adding *. HBM. XML to the cfg file.
