Java – how to map a class to different tables using hibernate / JPA annotations

At present, my persistence seems to be a very simple problem, but I can't seem to find a way:

I have two identical tables:

> tbl_ creditcard_ approved_ txns > tbl_ creditcard_ declined_ txns

The fields in the two are the same, and I have a class - transactions that represent all the corresponding fields in the table

I tried to map two different entities (one per table) to the above class In the old world, I created two hbms XML file, one in each table, and map them to transaction Then, I will use entity names during persistence to ensure that objects remain unchanged in the correct table, depending on the situation

At present, I try to use annotations to achieve the same function, but so far I have no luck mapping two entities to one class Is this possible

I am currently using a different method to extract all common fields (the same column name) into @ mappedsuperclass, and provide two independent classes (one for each entity) for superclasses (these classes are the same fields with different column names, if applicable)

Solution

Using @ mappedsuperclass, you will continue as follows:

@MappedSuperclass
public class Transaction ...

@Entity
@Table(name="tbl_creditcard_approved_txns")
public class DeclinedTransaction extends Transaction ...

@Entity
@Table(name="tbl_creditcard_declined_txns")
public class ApprovedTransaction extends Transaction ...

If necessary, use @ attributeoverride to override the column names between two types of transaction objects

Update: I see you want to map an @ entity to two tables in the same entitymanagerfactory... I don't think you can do this
