Spring JDBC returning auto-generated keys using PreparedStatementCreator and PreparedStatementCallback

In this post, we will look into how to retrieve auto-generated keys in JDBC. We will also explore usage of PreparedStatementCreator and PreparedStatementCallback in JdbcTemplate . There are cases when you rely on Database server to auto generate values for some columns of the table. E.g. auto increment primary key, creation_date or any other column while inserting records. There is a way with which you can retrieve those auto-generated keys when you execute the insert statement. Let's see how you can do this using Spring JDBC but first we will see what PreparedStatementCreator and PreparedStatementCallback interfaces are. What is PreparedStatementCreator? There are cases when you want to create PreparedStatement yourself. One use case is to return auto generated keys. In that case, Spring JDBC provides you an option to do so by providing implementation for PreparedStatementCreator . Let's create an implementation of PreparedStatementCreator which sets those options.
