ここに私のテーブルがあります:
CREATE TABLE `admin_log` (
`LOG_ID` bigint(20) NOT NULL AUTO_INCREMENT,
`USER_ID` bigint(20) NOT NULL,
`CREATION_DATE` timestamp NOT NULL DEFAULT '0000-00-00 00:00:00',
`ACTION` varchar(100) NOT NULL,
`DETAILS` varchar(100) DEFAULT NULL,
PRIMARY KEY (`LOG_ID`),
KEY `ADMIN_LOG_FK1` (`USER_ID`),
CONSTRAINT `ADMIN_LOG_FK1` FOREIGN KEY (`USER_ID`) REFERENCES `user_master` (`USER_ID`)
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8
そして、ここに私のエンティティがあります:
@Entity
@Table ( name = "admin_log" )
public class AdminLog {
private Long logId;
private UserMaster user;
...
@Id
@GeneratedValue ( strategy = IDENTITY )
@Column ( name = "LOG_ID", unique = true, nullable = false, length = 20 )
public Long getLogId () {
return logId;
}
public void setLogId ( Long logId ) {
this.logId = logId;
}
@ManyToOne
@JoinColumn ( name = "USER_ID" )
public UserMaster getUser () {
return user;
}
public void setUser ( UserMaster user ) {
this.user = user;
}
...
}
@Entity
@Table ( name = "user_master" )
public class UserMaster {
private Long userId;
...
@Id
@GeneratedValue ( strategy = IDENTITY )
@Column ( name = "USER_ID", unique = true, nullable = false, length = 20 )
public Long getUserId () {
return this.userId;
}
public void setUserId ( Long userId ) {
this.userId = userId;
}
...
}
from メソッドをAdminLog
使用して保存しようとすると、次のエラーが発生します。save()
HibernateTemplate
SEVERE: Column 'USER_ID' cannot be null
org.springframework.dao.DataIntegrityViolationException: could not insert [...AdminLog];
SQL [insert into admin_log (ACTION, CREATION_DATE, DETAILS, USER_ID) values (?, ?, ?, ?)];
constraint [null] nested exception is org.hibernate.exception.ConstraintViolationException: could not insert: [...AdminLog]
問題は、userId
間違いなく NOT null です! Hibernate が のプロパティuserId
から取得できないようです。私は何を間違っていますか?user
AdminLog
