I am trying to learn hibernate and I came across this little problem en route. Any help will be appreciated.
I have created a entity and a value typed object.
My entity is of type Person which is mapped to value object of Address.
The mapping is given below:
My question is can i query from a value typed object? When i query directly from the entity i get the details of the address value object too.
However what if a use case arises where i need to directly query from value object how would i do that.
I tried the below query
However on executing the query from code using the below code:
I get an exception which says:
Exception in
thread "main" java.lang.IllegalArgumentException: Parameter address does not exist as a
named parameter in [from valueobject.Address as a where
a.address =:address
]
at org.hibernate.impl.AbstractQueryImpl.setParameter(AbstractQueryImpl.java:356)
at org.hibernate.impl.AbstractQueryImpl.setString(AbstractQueryImpl.java:643)
at hibernatetrial.run.RunApplication.main(RunApplication.java:43)
Please help.
