Class BulkLoadingDaoSupport

java.lang.Object

net.solarnetwork.central.common.dao.jdbc.BulkLoadingDaoSupport

public class BulkLoadingDaoSupport
extends Object

Helper class for BulkLoadingDao implementations that uses a JDBC prepared statement for bulk loading operations.

To use this class, create an instance and configure the DataSource, PlatformTransactionManager, and jdbcCall to use, which can be a simple prepared statement or a callable statement. Then create a subclass of BulkLoadingDaoSupport.BulkLoadingContext and implement the doLoad(T, PreparedStatement, long) method to set the prepared statement parameters and execute the update for each entity to be loaded.
