Hibernate 一对多单向复合映射
我正在与以下场景作斗争: 我有两张桌子:Hibernate 一对多单向复合映射,hibernate,hibernate-mapping,Hibernate,Hibernate Mapping,我正在与以下场景作斗争: 我有两张桌子: RESULTS ( `L_ID` int(10) unsigned NOT NULL, `PRIZE` int(10) unsigned NOT NULL, `SECONDARY_PRIZE` int(10) unsigned NOT NULL, PRIMARY KEY (`L_ID`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1 | STATISTICS ( `L_ID` int(10) unsigned NOT
RESULTS (
`L_ID` int(10) unsigned NOT NULL,
`PRIZE` int(10) unsigned NOT NULL,
`SECONDARY_PRIZE` int(10) unsigned NOT NULL,
PRIMARY KEY (`L_ID`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 |
STATISTICS (
`L_ID` int(10) unsigned NOT NULL,
`F_TYPE` int(10) unsigned NOT NULL,
`RANK` varchar(2) NOT NULL,
`WINNERS` int(10) unsigned NOT NULL,
`PRIZE` int(10) unsigned NOT NULL,
PRIMARY KEY (`L_ID`,`F_TYPE`,`RANK`),
KEY `L_ID_FK_idx` (`L_ID`),
CONSTRAINT `L_ID` FOREIGN KEY (`L_ID`) REFERENCES `RESULTS` (`L_ID`) ON DELETE NO ACTION ON UPDATE NO ACTION
) ENGINE=InnoDB DEFAULT CHARSET=latin1 |
以及下列类别:
@Embeddable
public class StatisticId implements Serializable {
@Column(name = "L_ID", unique=false, nullable=false, updatable=true, insertable=true)
private long lId;
@Column(name = "F_TYPE", unique=false, nullable=false, updatable=true, insertable=true)
private int fType;
@Column(name = "RANK_ID", unique = false, nullable = false, updatable = true, insertable = true, length = 2)
private String rankId;
..Getters\Setters...
}
统计类别:
@Entity
@Table(name = "STATISTICS", uniqueConstraints = {})
public class Statistic implements Serializable {
@EmbeddedId
@AttributeOverrides({
@AttributeOverride(name = "lId", column = @Column(name = "L_ID", unique = false, nullable = false, insertable = true, updatable = true)),
@AttributeOverride(name = "fType", column = @Column(name = "F_TYPE", unique = false, nullable = false, insertable = true, updatable = true)),
@AttributeOverride(name = "rankId", column = @Column(name = "RANK_ID", unique = false, nullable = false, insertable = true, updatable = true, length = 2))
})
private StatisticId id;
@Column(name = "WINNERS", unique = false, nullable = false, updatable = true, insertable = true)
private long winners;
@Column(name = "PRIZE", unique = false, nullable = false, updatable = true, insertable = true)
private long prize;
}
最后是结果表:
@Entity
@Cache(usage = CacheConcurrencyStrategy.READ_ONLY)
@Table(name = "RESULTS")
public class Result extends Form {
@Id
@Column(name = "L_ID", unique = true, nullable = false, insertable = false, updatable = false)
private long lId;
@OneToMany(cascade = CascadeType.ALL, fetch = FetchType.EAGER)
@JoinTable(name="StatisticsResults",
joinColumns = { @JoinColumn(name="id.lId") },
inverseJoinColumns = { @JoinColumn(name="lId") }
)
private List<Statistic> statistics;
@Column(name = "PRIZE", unique = false, nullable = false, insertable = true, updatable = true)
private long prize;
@Column(name = "SECONDARY_PRIZE", unique = false, nullable = true, insertable = true, updatable = true)
private long secondaryPrize;
}
我在干什么
感谢您耐心阅读 解决了
问题出在HIbernate4.3测试版上,一旦我切换到4.2.1,它就像魔术一样工作
org.hibernate.AnnotationException: A Foreign key refering
com.btl.server.database.beans.Statistic from com.btl.server.database.beans.Result has the wrong
number of column. should be 2
