Following are the classes
- JdbcTemplate
- SimpleJdbcTemplate
- NamedParameterJdbcTemplate
- SimpleJdbcInsert
- SimpleJdbcCall
The most commonly used one is JdbcTemplate. This internally uses the JDBC API and has the advantage that we don't need to create connection, statement, start transaction,commit transaction and close connection to execute different queries. All these are handled by JdbcTemplate itself. The developer can focus on executing the query directly.
