It provides meta-data processing to simplify the code * needed to construct a basic insert statement. All you need to provide is the * name of the table and a Map containing the column names and the column values. * * <p>The meta-data processing is based on the DatabaseMetaData provided by the * JDBC driver. As long as the JDBC driver can provide the names of the columns * for a specified table than we can rely on this auto-detection feature. If that * is not the case, then the column names must be specified explicitly. * * <p>The actual insert is being handled using Spring's {@link JdbcTemplate}. * * <p>Many of the configuration methods return the current instance of the * SimpleJdbcInsert to provide the ability to chain multiple ones together * in a "fluent" interface style. * * @author Thomas Risberg * @author Juergen Hoeller * @since 2.5 * @see java.sql.DatabaseMetaData * @see org.springframework.jdbc.core.JdbcTemplate */ public class SimpleJdbcInsert extends AbstractJdbcInsert implements SimpleJdbcInsertOperations { /** * Constructor that takes one parameter with the JDBC DataSource to use when creating the * JdbcTemplate. * @param dataSource the {@code DataSource} to use * @see org.springframework.jdbc.core.JdbcTemplate#setDataSource */ public SimpleJdbcInsert(DataSource dataSource) { super(dataSource); } /** * Alternative Constructor that takes one parameter with the JdbcTemplate to be used. * @param jdbcTemplate the {@code JdbcTemplate} to use * @see org.springframework.jdbc.core.JdbcTemplate#setDataSource */ public SimpleJdbcInsert(JdbcTemplate jdbcTemplate) { super(jdbcTemplate); } @Override public SimpleJdbcInsert withTableName(String tableName) { setTableName(tableName); return this; } @Override public SimpleJdbcInsert withSchemaName(String schemaName) { setSchemaName(schemaName); return this; } @Override public SimpleJdbcInsert withCatalogName(String catalogName) { setCatalogName(catalogName); return this; } @Override public SimpleJdbcInsert usingColumns(String... columnNames) { setColumnNames(Arrays.asList(columnNames)); return this; } @Override public SimpleJdbcInsert usingGeneratedKeyColumns(String... columnNames) { setGeneratedKeyNames(columnNames); return this; } @Override public SimpleJdbcInsertOperations withoutTableColumnMetaDataAccess() { setAccessTableColumnMetaData(false); return this; } @Override public SimpleJdbcInsertOperations includeSynonymsForTableColumnMetaData() { setOverrideIncludeSynonymsDefault(true); return this; } @Override public int execute(Map<String, ?> args) { return doExecute(args); } @Override public int execute(SqlParameterSource parameterSource) { return doExecute(parameterSource); } @Override public Number executeAndReturnKey(Map<String, ?> args) { return doExecuteAndReturnKey(args); } @Override public Number executeAndReturnKey(SqlParameterSource parameterSource) { return doExecuteAndReturnKey(parameterSource); } @Override public KeyHolder executeAndReturnKeyHolder(Map<String, ?> args) { return doExecuteAndReturnKeyHolder(args); } @Override public KeyHolder executeAndReturnKeyHolder(SqlParameterSource parameterSource) { return doExecuteAndReturnKeyHolder(parameterSource); } @Override @SuppressWarnings("unchecked") public int[] executeBatch(Map<String, ?>... batch) { return doExecuteBatch(batch); } @Override public int[] executeBatch(SqlParameterSource... batch) { return doExecuteBatch(batch); } }
