私は休止状態が初めてで、MySQl、Hibernate、および Struts を使用するアプリケーションに取り組んでいます。特定のコードに対して常に次のエラーが発生します。このエラーについてグーグルで検索しましたが、それらのスレッドは役に立ちませんでした。
エラー
javax.servlet.ServletException: Could not execute JDBC batch update
at org.apache.struts.action.RequestProcessor.processException(RequestProcessor.java:516)
....
コード
Session session = new HibernateSession().currentSession(this.getServlet().getServletContext());
if(auctionform.getId() == null || auctionform.getId().intValue() == 0){
auction.setId(null);
auctionform.setId(null);
}else{
auction.setId(auctionform.getId());
Criteria criteria = session.createCriteria(Auction.class);
criteria.add(Restrictions.idEq(Integer.valueOf(req.getParameter("id"))));
auction = (Auction) criteria.uniqueResult();
}
Boolean isAuctionActive = false;
Calendar currentDate = Calendar.getInstance();
SimpleDateFormat formatter= new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
Date auctionEndingDate = DateUtils.getDate(req, "auctionenddate");
Date todaysDate = formatter.parse(formatter.format(currentDate.getTime()));
if(auctionEndingDate.after(todaysDate)){
isAuctionActive = true;
}
auction.setDescription(auctionform.getDescription());
auction.setDate(auctionform.getDate());
auction.setCurrentprice(auctionform.getCurrentprice());
....some code
Attachment attachment1 = AttachmentUtils.saveAttachment(auctionform, session, auction, 0);
Attachment attachment2 = AttachmentUtils.saveAttachment(auctionform, session, auction, 1);
Attachment attachment3 = AttachmentUtils.saveAttachment(auctionform, session, auction, 2);
Transaction transaction = session.beginTransaction();
if(attachment1!=null){
session.save(attachment1.getDbFile());
session.save(attachment1.getThmnailDbFile());
session.save(attachment1);
auction.setFirstimage(attachment1);
}
if(attachment2!=null){
session.save(attachment2.getDbFile());
session.save(attachment2.getThmnailDbFile());
session.save(attachment2);
auction.setSecoundimage(attachment2);
}
if(attachment3 != null){
session.save(attachment3.getDbFile());
session.save(attachment3.getThmnailDbFile());
session.save(attachment3);
auction.setSignimage(attachment3);
}
session.saveOrUpdate(auction);
transaction.commit();
session.flush();
私は常にこのエラーをtransaction.commit()行で受け取ります。何が問題なのかわかりません。
アップデート：
私はlog4jをセットアップし、完全なスタックトレースは以下のとおりです。

列に日本語のものを保存しようとしているので、テーブルの照合をCOLLATE = ujis_japanese_ciおよびUTF-8に更新しようとしましたが、まだ効果がありません。
解決：
テーブルの照合とそのすべてのフィールドをutf8-utf8_binに設定すると、うまくいきました。
