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，我把所有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是能够获取的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，修改了一下该类

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 danielinbitiint int_p = precision>Integer.MAX_VALUE?Integer.MAX_VALUE:(int)precision;//add by danielinbiti,这么修改反正基于目前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;}
