broken column mapping exception on @OneToOne mapping
Hi all,
I got an exception on my entity mappings. The codes are as follows:
table test (
id
name
)
table deleted_test (
test_id
person_id
deleted_date
)
@Embeddable
class PK {
int test_id;
int person_id;
...
}
@Entity
@Table(name="deleted_test")
class DeletedTest {
PK pk;
Test test;
Person person;
...
@EmbeddedId
public PK getPk(){
return pk;
}
...setPk...
@OneToOne(cascade=CascadeType.ALL,fetch=FetchType.EAGER)
@JoinColumn(name="Test_ID", nullable = false, insertable = false, updatable = false)
public Test getTest() {
return test;
}
public void setTest(Test Test) {
this.test = test;
}
@ManyToOne
@JoinColumn(name="PERSON_ID", nullable=false, insertable = false, updatable = false)
public Person getPerson() {
return person;
}
public void setPerson(Person person) {
this.person = person;
}
...
}When I run it on JBoss4.0.4GA and EJB3 RC8, I always got the following exceptions:
org.hibernate.MappingException: broken column mapping for: test.id of: DeletedTest at org.hibernate.persister.entity.AbstractPropertyMapping.initPropertyPaths(AbstractPropertyMapping.java:122) at org.hibernate.persister.entity.AbstractPropertyMapping.initIdentifierPropertyPaths(AbstractPropertyMapping.java:176) at org.hibernate.persister.entity.AbstractPropertyMapping.initPropertyPaths(AbstractPropertyMapping.java:160) at org.hibernate.persister.entity.AbstractEntityPersister.initOrdinaryPropertyPaths(AbstractEntityPersister.java:1628) at org.hibernate.persister.entity.AbstractEntityPersister.initPropertyPaths(AbstractEntityPersister.java:1656) at org.hibernate.persister.entity.AbstractEntityPersister.postConstruct(AbstractEntityPersister.java:2699) at org.hibernate.persister.entity.SingleTableEntityPersister.<init>(SingleTableEntityPersister.java:386) at org.hibernate.persister.PersisterFactory.createClassPersister(PersisterFactory.java:55) at org.hibernate.impl.SessionFactoryImpl.<init>(SessionFactoryImpl.java:223) at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1213) at org.hibernate.ejb.Ejb3Configuration.buildEntityManagerFactory(Ejb3Configuration.java:631) at org.hibernate.ejb.Ejb3Configuration.createEntityManagerFactory(Ejb3Configuration.java:760) at org.hibernate.ejb.Ejb3Configuration.createContainerEntityManagerFactory(Ejb3Configuration.java:350) at org.hibernate.ejb.HibernatePersistence.createContainerEntityManagerFactory(HibernatePersistence.java:119) at org.jboss.ejb3.entity.PersistenceUnitDeployment.start(PersistenceUnitDeployment.java:264) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at org.jboss.ejb3.ServiceDelegateWrapper.startService(ServiceDelegateWrapper.java:99) at org.jboss.system.ServiceMBeanSupport.jbossInternalStart(ServiceMBeanSupport.java:289) at org.jboss.system.ServiceMBeanSupport.jbossInternalLifecycle(ServiceMBeanSupport.java:245) at sun.reflect.GeneratedMethodAccessor3.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at org.jboss.mx.interceptor.ReflectedDispatcher.invoke(ReflectedDispatcher.java:155)
However,if I changed the test mapping to ManyToOne from OneToOne, no exceptions occured. I want to know the OneToOne mapping here is wrong or not. I appreciate any directions. Thank you in advance.
