我不确定我的机会，但我需要将一个 JDBC 事务与休眠事务合并。仅当两个事务都成功执行时，才应提交事务。但是看起来由于自动提交是错误的，JDBC事务正在锁定表，我最终得到了异常
12:47:52,605 WARN JDBCExceptionReporter:77 - SQL Error: 1205, SQLState: 41000
12:47:52,605 ERROR JDBCExceptionReporter:78 - Lock wait timeout exceeded; try restarting transaction
下面是方法
@Transactional
public void myMthod(int fieldId, int currentActiveOrgId, int formId)
{
Savepoint savePoint = null;
String savepointName = null;
try{
//Set auto commit false for sql statemnt
getDBConnection().setAutoCommit(false);
savepointName = "deleteDynamicField"+this.getClass().hashCode();
savePoint = getDBConnection().setSavepoint(savepointName);
DynamicQueryManager obj = DynamicQueryMgrObjFactory.getDynamicQueryMgrObj(currentActiveOrgId, formId);
//Resposible for sql statement
obj.deleteDynTblRec(fieldId);
//Resposible for hql transaction (part of the code generating exception)
dynDao.deleteDynamicField(fieldId);
DynamicQueryUtil.getDBConnection().commit();
}catch (Exception e) {
try {
logger.error("", e);
DynamicQueryUtil.getDBConnection().rollback(savePoint);
DynamicQueryUtil.getDBConnection().releaseSavepoint(savePoint);
}catch (Exception ex) {
logger.error("Failed to do rollback for savePoint "+savepointName+" ", ex);
}
}finally{
try{
DynamicQueryUtil.getDBConnection().commit();
DynamicQueryUtil.getDBConnection().setAutoCommit(true);
}catch (Exception e) {
logger.error("", e);
}
}
}

在这里，我想在休眠事务中创建一个简单的 JDBC 事务，这样如果发生任何异常，它将回滚 JDBC 事务以及休眠事务。是的，由于应用程序的某些限制，我无法将 JDBC 代码的 sql 部分迁移到休眠状态。提前致谢。堆栈溢出很棒。
