從休眠 5.2.17 升級(jí)到 5.3.6 后，我收到此錯(cuò)誤：Caused by: org.h2.jdbc.JdbcSQLException: Schéma "ENHANCED" non trouvéSchema "ENHANCED" not found; SQL statement:call next value for enhanced.SequenceStyleGenerator [90079-197] at org.h2.engine.SessionRemote.done(SessionRemote.java:623) ~[h2-1.4.197.jar:1.4.197] at org.h2.command.CommandRemote.prepare(CommandRemote.java:85) ~[h2-1.4.197.jar:1.4.197] at org.h2.command.CommandRemote.<init>(CommandRemote.java:51) ~[h2-1.4.197.jar:1.4.197] at org.h2.engine.SessionRemote.prepareCommand(SessionRemote.java:493) ~[h2-1.4.197.jar:1.4.197] at org.h2.jdbc.JdbcConnection.prepareCommand(JdbcConnection.java:1247) ~[h2-1.4.197.jar:1.4.197] at org.h2.jdbc.JdbcPreparedStatement.<init>(JdbcPreparedStatement.java:76) ~[h2-1.4.197.jar:1.4.197] at org.h2.jdbc.JdbcConnection.prepareStatement(JdbcConnection.java:304) ~[h2-1.4.197.jar:1.4.197] at com.mchange.v2.c3p0.impl.NewProxyConnection.prepareStatement(NewProxyConnection.java:567) ~[c3p0-0.9.5.2.jar:0.9.5.2] at org.hibernate.engine.jdbc.internal.StatementPreparerImpl$1.doPrepare(StatementPreparerImpl.java:87) ~[hibernate-core-5.3.6.Final.jar:5.3.6.Final] at org.hibernate.engine.jdbc.internal.StatementPreparerImpl$StatementPreparationTemplate.prepareStatement(StatementPreparerImpl.java:172) ~[hibernate-core-5.3.6.Final.jar:5.3.6.Final]使用 hibernate 5.2 它可以按預(yù)期工作，但不再使用 hibernate 5.3。這里的遷移指南：https : //github.com/hibernate/hibernate-orm/blob/5.3/migration-guide.adoc不引用序列生成器的任何更改?？赡苁鞘裁磫?wèn)題 ？

我發(fā)現(xiàn)這是 hibernate 5.3 的新行為：
在SequenceStyleGenerator.determineSequenceName添加代碼的方法中：
final Boolean preferGeneratorNameAsDefaultName = serviceRegistry.getService( ConfigurationService.class )
.getSetting( AvailableSettings.PREFER_GENERATOR_NAME_AS_DEFAULT_SEQUENCE_NAME, StandardConverters.BOOLEAN, true );
if ( preferGeneratorNameAsDefaultName ) {
final String generatorName = params.getProperty( IdentifierGenerator.GENERATOR_NAME );
if ( StringHelper.isNotEmpty( generatorName ) ) {
fallbackSequenceName = generatorName;
}
}
新的默認(rèn)行為是使用生成器名稱(chēng)作為序列名稱(chēng)。所以從hibernate 5.2遷移到5.3有兩種可能：
將生成器名稱(chēng)更改為序列名稱(chēng)
通過(guò)在休眠配置（或生成器參數(shù)）中設(shè)置hibernate.model.generator_name_as_sequence_name為不使用生成器名稱(chēng)，恢復(fù)到休眠 5.2- 行為false
