我在struts2 + hibernate应用程序中遇到了一个错误。我试图在数据库上保存实体，然后收到此异常消息：
Incorrect date value: '' for column 'data_creazione' at row 1
这是我的代码：
...
DocumentoCondivisoDAO cdao = new DocumentoCondivisoDAO();
DocumentoCondiviso doc = new DocumentoCondiviso("test_document", "mime/tipe", new Date(), 100000, utente, null);
cdao.save(doc);
这是调试信息：
Hibernate: insert into ts_documenti_condivisi (data_creazione, id_destinatario, dimensione_documento, nome_documento, id_proprietario, tipo_documento) values (?, ?, ?, ?, ?, ?)

我想澄清一下，另一个类中的相同代码就像一个魅力......我做错了什么？
EDIT1：构造函数
public DocumentoCondiviso(String nomeDocumento, String tipoDocumento, Date dataCreazione,
int dimensioneDocumento, Utenti proprietario, Utenti destinatario){
this.nomeDocumento = nomeDocumento;
this.tipoDocumento = tipoDocumento;
this.dataCreazione = dataCreazione;
this.dimensioneDocumento = dimensioneDocumento;
this.proprietario = proprietario;
this.destinatario = destinatario;
}
MySQL数据库上的字段类型是＆＃34; DATE＆＃34; ....我有很多与此类似的实体正常工作。
