Can a JPA entity have a field not mapped to a DB column
Is it possible for a JPA entity to have a field which is not mapped to any column in the data base table. Basically I need to store some additional data on my front end but I do not want to create an extra column in the table for this.

Marking @Transient annotation solve this problem but it will work after restart host server(application/web).

Just mark the field or getter with @javax.persistence.Transient annotation.
The data stored there will not be persisted, nor the ddl generator, if you use any, will pick that one up as an additional column of the table.
