"SettingsFactory" no longer checks for presence of "supportsGetGeneratedKeys" before calling it ----------------------------------------------------------------------------------------------- Key: HHH-5307 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5307 Project: Hibernate Core Issue Type: Bug Affects Versions: 3.5.2 Reporter: Weinan Xiong Same issue occured again like HHH-5017. The Hibernate version is 3.5.2. When I am using DB2 type 2 driver, I will get the following error: Initial SessionFactory Creaion Failed.java.lang.AbstractMethodError The temperate solution will add this property into xxx.cfg.xml file: hibernate.temp.use_jdbc_metadata_defaults= false. When you look at the source code for SettingsFactory, you can tell the supportsGetGeneratedKeys has never been checked before getting call. boolean useJdbcMetadata = PropertiesHelper.getBoolean( "hibernate.temp.use_jdbc_metadata_defaults", props, true ); if ( useJdbcMetadata ) { try { Connection conn = connections.getConnection(); try { DatabaseMetaData meta = conn.getMetaData(); log.info( "RDBMS: " + meta.getDatabaseProductName() + ", version: " + meta.getDatabaseProductVersion() ); log.info( "JDBC driver: " + meta.getDriverName() + ", version: " + meta.getDriverVersion() ); dialect = DialectFactory.buildDialect( props, conn ); jdbcSupport = JdbcSupportLoader.loadJdbcSupport( conn ); metaSupportsScrollable = meta.supportsResultSetType( ResultSet.TYPE_SCROLL_INSENSITIVE ); metaSupportsBatchUpdates = meta.supportsBatchUpdates(); metaReportsDDLCausesTxnCommit = meta.dataDefinitionCausesTransactionCommit(); metaReportsDDLInTxnSupported = !meta.dataDefinitionIgnoredInTransactions(); metaSupportsGetGeneratedKeys = meta.supportsGetGeneratedKeys(); } catch ( SQLException sqle ) { log.warn( "Could not obtain connection metadata", sqle ); } finally { connections.closeConnection( conn ); } }
