hibernate4中HHH000273的错误

今天配置hibernate4。发现报

17:55:06,815  INFO AbstractPoolBackedDataSource:522 - Initializing c3p0 pool... com.mchange.v2.c3p0.ComboPooledDataSource [ acquireIncrement -> 1, acquireRetryAttempts -> 30, acquireRetryDelay -> 1000, autoCommitOnClose -> false, automaticTestTable -> null, breakAfterAcquireFailure -> false, checkoutTimeout -> 0, connectionCustomizerClassName -> null, connectionTesterClassName -> com.mchange.v2.c3p0.impl.DefaultConnectionTester, dataSourceName -> 1hge16q9a8u2d4lyv35wl|5a6efc31, debugUnreturnedConnectionStackTraces -> false, description -> null, driverClass -> oracle.jdbc.driver.OracleDriver, factoryClassLocation -> null, forceIgnoreUnresolvedTransactions -> false, identityToken -> 1hge16q9a8u2d4lyv35wl|5a6efc31, idleConnectionTestPeriod -> 0, initialPoolSize -> 3, jdbcUrl -> jdbc:oracle:thin:@192.168.1.229:1521:WDRPT, maxAdministrativeTaskTime -> 0, maxConnectionAge -> 0, maxIdleTime -> 5, maxIdleTimeExcessConnections -> 0, maxPoolSize -> 20, maxStatements -> 0, maxStatementsPerConnection -> 0, minPoolSize -> 2, numHelperThreads -> 3, preferredTestQuery -> null, properties -> {user=******, password=******}, propertyCycle -> 0, statementCacheNumDeferredCloseThreads -> 0, testConnectionOnCheckin -> false, testConnectionOnCheckout -> false, unreturnedConnectionTimeout -> 0, userOverrides -> {}, usesTraditionalReflectiveProxies -> false ]
  17:55:07,741  WARN TypeInfo:126 - HHH000273: Error accessing type info result set : java.sql.SQLException: 数字溢出

数字溢出。搜了一下。都说映射文件错误了。我把全部配置的映射文件都去掉，还是报错，跟代码一下，是c3p0的获取meta的问题

public static LinkedHashSet<TypeInfo> extractTypeInfo(DatabaseMetaData metaData) {
		final LinkedHashSet<TypeInfo> typeInfoSet = new LinkedHashSet<TypeInfo>();
		try {
			final ResultSet resultSet = metaData.getTypeInfo();
			try {
				while ( resultSet.next() ) {
					typeInfoSet.add(
							new TypeInfo(
									resultSet.getString( "TYPE_NAME" ),
									resultSet.getInt( "DATA_TYPE" ),
									interpretCreateParams( resultSet.getString( "CREATE_PARAMS" ) ),
									resultSet.getBoolean( "UNSIGNED_ATTRIBUTE" ),
									resultSet.getInt( "PRECISION" ),//commend by danielinbiti,blob字段时，这个数字超出了int的范围。用long是可以获取的
									resultSet.getShort( "MINIMUM_SCALE" ),
									resultSet.getShort( "MAXIMUM_SCALE" ),
									resultSet.getBoolean( "FIXED_PREC_SCALE" ),
									resultSet.getString( "LITERAL_PREFIX" ),
									resultSet.getString( "LITERAL_SUFFIX" ),
									resultSet.getBoolean( "CASE_SENSITIVE" ),
									TypeSearchability.interpret( resultSet.getShort( "SEARCHABLE" ) ),
									TypeNullability.interpret( resultSet.getShort( "NULLABLE" ) )
							)
					);
				}
			}
			catch ( SQLException e ) {
				LOG.unableToAccessTypeInfoResultSet( resultSet.getString( "TYPE_NAME" )+","+resultSet.getInt( "DATA_TYPE" ) );
				LOG.unableToAccessTypeInfoResultSet( e.toString() );
			}
			finally {
				try {
					resultSet.close();
				}
				catch ( SQLException e ) {
					LOG.unableToReleaseTypeInfoResultSet();
				}
			}
		}
		catch ( SQLException e ) {
			LOG.unableToRetrieveTypeInfoResultSet( e.toString() );
		}

		return typeInfoSet;
	}

于是，改动了一下该类

public static LinkedHashSet<TypeInfo> extractTypeInfo(DatabaseMetaData metaData) {
		final LinkedHashSet<TypeInfo> typeInfoSet = new LinkedHashSet<TypeInfo>();
		try {
			final ResultSet resultSet = metaData.getTypeInfo();
			try {
				while ( resultSet.next() ) {
					long precision = resultSet.getLong( "PRECISION" );//add by danielinbiti
					int int_p = precision>Integer.MAX_VALUE?Integer.MAX_VALUE:(int)precision;//add by danielinbiti,这么改动反正基于眼下该方法的逻辑是没问题的。
					typeInfoSet.add(
							new TypeInfo(
									resultSet.getString( "TYPE_NAME" ),
									resultSet.getInt( "DATA_TYPE" ),
									interpretCreateParams( resultSet.getString( "CREATE_PARAMS" ) ),
									resultSet.getBoolean( "UNSIGNED_ATTRIBUTE" ),
									int_p,
									resultSet.getShort( "MINIMUM_SCALE" ),
									resultSet.getShort( "MAXIMUM_SCALE" ),
									resultSet.getBoolean( "FIXED_PREC_SCALE" ),
									resultSet.getString( "LITERAL_PREFIX" ),
									resultSet.getString( "LITERAL_SUFFIX" ),
									resultSet.getBoolean( "CASE_SENSITIVE" ),
									TypeSearchability.interpret( resultSet.getShort( "SEARCHABLE" ) ),
									TypeNullability.interpret( resultSet.getShort( "NULLABLE" ) )
							)
					);
				}
			}
			catch ( SQLException e ) {
				LOG.unableToAccessTypeInfoResultSet( e.toString() );
			}
			finally {
				try {
					resultSet.close();
				}
				catch ( SQLException e ) {
					LOG.unableToReleaseTypeInfoResultSet();
				}
			}
		}
		catch ( SQLException e ) {
			LOG.unableToRetrieveTypeInfoResultSet( e.toString() );
		}

		return typeInfoSet;
	}
