Question

尝试在Eclipse Mars中使用Hibernate Tool Code时，我遇到了这个问题。我已经在我的NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; NSString *path1 = [NSString stringWithFormat:@"%@/firstPart.caf",documentsDirectory]; NSString *path2 = [NSString stringWithFormat:@"%@/New-Recording.caf",documentsDirectory]; AVAsset *avAsset1 = [AVURLAsset URLAssetWithURL:[NSURL fileURLWithPath:path1] options:nil]; AVAsset *avAsset2 = [AVURLAsset URLAssetWithURL:[NSURL fileURLWithPath:path2] options:nil]; AVMutableComposition *composition = [[AVMutableComposition alloc] init]; // [composition addMutableTrackWithMediaType:AVMediaTypeAudio preferredTrackID:kCMPersistentTrackID_Invalid]; AVMutableCompositionTrack *track = [composition addMutableTrackWithMediaType:AVMediaTypeAudio preferredTrackID:kCMPersistentTrackID_Invalid]; AVAssetTrack *assetTrack1; AVAssetTrack *assetTrack2; if ([avAsset1 tracksWithMediaType:AVMediaTypeAudio].count > 0) { assetTrack1 = [[avAsset1 tracksWithMediaType:AVMediaTypeAudio] objectAtIndex:0]; assetTrack2 = [[avAsset2 tracksWithMediaType:AVMediaTypeAudio] objectAtIndex:0]; } NSError *error; CMTime insertionPoint = kCMTimeZero; [track insertTimeRange:CMTimeRangeMake(kCMTimeZero, avAsset1.duration) ofTrack:assetTrack1 atTime:insertionPoint error:nil]; insertionPoint = CMTimeAdd(insertionPoint, avAsset1.duration); [track insertTimeRange:CMTimeRangeMake(kCMTimeZero, avAsset2.duration) ofTrack:assetTrack2 atTime:insertionPoint error:nil]; NSURL *outPutUrl = [NSURL fileURLWithPath:[NSString stringWithFormat:@"%@/mergedFilePart1.caf",documentsDirectory]]; AVAssetExportSession *exportSession = [AVAssetExportSession exportSessionWithAsset:composition presetName:AVAssetExportPresetAppleM4A]; exportSession.outputURL = outPutUrl; exportSession.outputFileType = AVFileTypeAppleM4A; [exportSession exportAsynchronouslyWithCompletionHandler:^{ if (AVAssetExportSessionStatusCompleted == exportSession.status) { NSLog(@"AVAssetExportSessionStatusCompleted"); [self mergeAudioPart2]; } else if (AVAssetExportSessionStatusFailed == exportSession.status) { NSLog(@"%ld",(long)exportSession.status); NSLog(@"AVAssetExportSessionStatusFailed"); } else { NSLog(@"Export Session Status: %ld", (long)exportSession.status); } }];中添加了方言，包括hibernate.cfg.xml。

org.hibernate.HibernateException：'hibernate.dialect' 此处输入代码必须在没有连接可用时设置

的 hibernate.cfg.xml中

sqljdbc4.jar

hibernate.reveng.xml中

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
                                         "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

</hibernate-configuration>

我通过在＆＃34; Main＆＃34;中将Hibernate版本从5.1更改为4.3来解决了这个问题。 Hibernate配置对话框的选项卡。

Hibernate代码生成：org.hibernate.HibernateException：当没有连接可用时，必须设置'hibernate.dialect'
