休止状態5でObjectNameNormalizerを取得する方法

Question

休止状態のバージョンを3から5.0にアップグレードしようとしています。

hibernate5でObjectNameNormalizerを取得する方法をアドバイスできますか？私の現在のコードでは、コードを使ってその場でプロパティを設定しているので、変更できないセッションファクトリを取得するためにConfigurationを使用しています。このソリューションを試してみてください

Mappings mappings = c.createMappings(); (this method does not exist in 5.0) 

props.put(TableGenerator.IDENTIFIER_NORMALIZER, mappings.getObjectNameNormalizer()); 

Answer 1

- コードの下

は休止状態5に再書き込みする必要があります。我々は同じ問題に直面した。
