Gestion des blob via topia et hibernate
by Eric Chatellier 20 Sep '12

20 Sep '12

Bonjour, J'ai fait un peu de recherche pour gérer des blob dans topia/hibernate. Le besoin étant de stocké les fichiers dans la base de données pour faciliter la gestion. Solution 1 ========== La première solution que j'ai testé à consister à représenter les données binaire dans le modèle uml via : java.lang.byte[] et a changer le type hibernate via model.tagvalue.java.lang.byte[]=binary ca fonctionnais, mais par contre, le binary a une taille limitée Solution 2 ========== Même méthode que la solution 1, mais en changeant la tagvalue en model.tagvalue.java.lang.byte[]=blob Mais cela ne fonctionne pas non plus: Caused by: java.lang.ClassCastException: [B cannot be cast to java.sql.Blob at org.hibernate.type.descriptor.java.BlobTypeDescriptor.areEqual(BlobTypeDescriptor.java:47) at org.hibernate.type.AbstractStandardBasicType.isEqual(AbstractStandardBasicType.java:184) at org.hibernate.type.AbstractStandardBasicType.isSame(AbstractStandardBasicType.java:169) at org.hibernate.type.AbstractStandardBasicType.isDirty(AbstractStandardBasicType.java:214) at org.hibernate.type.AbstractStandardBasicType.isDirty(AbstractStandardBasicType.java:210) at org.hibernate.type.TypeHelper.findDirty(TypeHelper.java:295) Solution 3 ========== La solution actuelle à laquelle je suis arrivée mais qui a des inconvénients de modélisation est la suivante: * modélisation UML en type : java.sql.Blob * tag value : model.tagvalue.java.sql.Blob=blob Mais : * à l'enregistrement, le code métier doit manipuler des blob via l’implémentation fournit par hibernate: is = new FileInputStream(file); // create blob object Blob blob = Hibernate.createBlob(is); // code déprécié is.close(); entity.setData(blob); * à la lecture (download), actuellement c'est même l'ui struts qui dépent de la couche sql à cause d'un throws: public InputStream getInputStream() { InputStream inputStream = null; try { inputStream = analyzeFile.getData().getBinaryStream(); } catch (SQLException ex) { // damned throws } return inputStream; } Voilà, j'ai pas de solution plus propre que ca pour le moment. -- Éric Chatellier <chatellier(a)codelutin.com> Tel: 02.40.50.29.28 http://www.codelutin.com

Vidage automatique du cache hibernate
by Eric Chatellier 27 Aug '12

27 Aug '12

Bonjour, Nous avons trouvé dans une application utilisant topia une fuite mémoire due au cache hibernate. En effet, comme le confirme la documentation [1], il n'est pas libéré tant que la session n'est pas close: "The Session caches every object that is in a persistent state (watched and checked for dirty state by Hibernate). If you keep it open for a long time or simply load too much data, it will grow endlessly until you get an OutOfMemoryException. One solution is to call clear() and evict() to manage the Session cache, but you should consider a Stored Procedure if you need mass data operations. Some solutions are shown in Chapitre 14, Traitement par lot. Keeping a Session open for the duration of a user session also means a higher probability of stale data." Dans le cas de notre application, il faudrait que après chaque commit, un session.clear() soit fait automatiquement. Le ticket a été créé dans ce but: http://www.nuiton.org/issues/2284 [1] : http://docs.jboss.org/hibernate/orm/3.5/reference/fr-FR/html/transactions.h… -- Éric Chatellier <chatellier(a)codelutin.com> Tel: 02.40.50.29.28 http://www.codelutin.com
