You are using the most efficient way. I tried to look into converting the jsonb value directly to some json parser in the jdbc driver, but it turned out the the server always sends jsonb as a serialized string instead of the faster-to-parse internal jsonb storage format.

Subject: [JDBC] best way to convert JSONB object from result
 
Hi:

I am trying to convert to a Java or Map object
from resultset with a jsonb column.
Currently, I am using

String jsonString = resultSet.getString("jsonb_column_name")

then I convert from jsonString to a Map<String,Object>  or a Java class object.

This is obviously inefficient.  What would be most efficient (not too complicated)

Thanks in Advance
