我正在尝试使用联结表(Person_Address)建模1:N(人员和地址)关系。
1.Person(personId PK)
2.Address(addressId PK)
3.PersonAddress( personId,addressId复合PK, personId FK引用人, addressid FK引用地址 )
@Entity
public class Person {
@OneToMany
@JoinTable(
name="PersonAddress",
joinColumns = @JoinColumn( name="personId"),
inverseJoinColumns = @JoinColumn( name="addressId")
)
public Set<Address> getAddresses() {...} ...
}
我遇到以下错误。无法找到任何解决方案。
按引起:org.hibernate.MappingException:无法确定类型:com.realestate.details.Address,在表:人,对于列:
[org.hibernate.mapping.Column(地址)]在org.hibernate.mapping.SimpleValue.getType(SimpleValue.java:269)在org.hibernate.mapping.SimpleValue.isValid(SimpleValue.java:253)在org.hibernate.mapping.Property.isValid(Property.java:185)在org.hibernate.mapping.PersistentClass.validate(PersistentClass.java:440)在org.hibernate.mapping.RootClass.validate(RootClass.java:192)在org.hibernate.cfg.Configuration.validate(Configuration.java:1108)在org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1293)
