I'm essentially looking for a "@Ignore" type annotation with which I can stop a particular field from being persisted. How can this be achieved?

To ignore a field, annotate it with @Transient so it will not be mapped by hibernate.
@Transient annotation is used to ignore a field to not persist in database in JPA, where as transient key word used to ignore a field from serialization. The field annotated with @Transient still can be serialized, but the field declared with transient keyword not to be persisted and not to be serialized.
When persisting Java objects into database records using an Object-Relational Mapping (ORM) framework, we often want to ignore certain fields. If the framework is compliant with the Java Persistence API (JPA), we can add the @Transient annotation to these fields.
Every non static non transient property (field or method depending on the access type) of an entity is considered persistent , unless you annotate it as @Transient . So you can use @Transient annotation on the property you do not wish to create a column for in database.
@Transient complies with your needs.
