Class SimpleJsonbConverter

java.lang.Object

de.terrestris.shoguncore.hibernate.SimpleJsonbConverter

All Implemented Interfaces:

javax.persistence.AttributeConverter<Map<String,String>,String>

public class SimpleJsonbConverter
extends Object
implements javax.persistence.AttributeConverter<Map<String,String>,String>

A JPA converter that can be used to convert jsonb fields into a map. Currently only works with 'simple' json content (only one level objects like {"name": "peter", "someprop": 345}).

Please note that you'll need to switch to pgjdbc-ng from https://github.com/impossibl/pgjdbc-ng instead of using the standard postgres driver.

Please also note that if you want optimal performance you'll need to add an index manually, hibernate can only create btree indexes.
