How do I create a POJO WITH ANNOTATIONS so that hibernate will create the table below upon mapping? one column is followEE
and one is followER
.
CREATE TABLE friends(
id INT(11) UNSIGNED NOT NULL AUTO_INCREMENT,
followee_id INT(11) UNSIGNED NOT NULL,
follower_id INT(11) UNSIGNED NOT NULL,
start_time TIMESTAMP NOT NULL,
end_time TIMESTAMP NOT NULL,
PRIMARY KEY(id),
KEY idx_fk_friends_followee_id (followee_id),
KEY idx_fk_friends_follower_id (follower_id),
CONSTRAINT `fk_friends_followee_id` FOREIGN KEY (followee_id) REFERENCES user (id) ON DELETE RESTRICT ON UPDATE CASCADE,
CONSTRAINT `fk_friends_follower_id` FOREIGN KEY (follower_id) REFERENCES user (id) ON DELETE RESTRICT ON UPDATE CASCADE
)ENGINE=MyISAM DEFAULT CHARSET=utf8;
I am not sure what is your problem, as that is quite straight-forward I think:
@Entity
public class Friend {
@Id
private Long id;
@ManyToOne
private User follower;
@ManyToOne
private User followee;
}
