我是hibernate的新手，我正在开发一个使用MySQl，Hibernate和Struts的应用程序。对于给定的代码，我总是得到以下错误。我确实谷歌这个错误，但那些线程没有帮助。
错误
javax.servlet.ServletException: Could not execute JDBC batch update
at org.apache.struts.action.RequestProcessor.processException(RequestProcessor.java:516)
....
代码
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();
我总是在transaction.commit()行收到此错误。我没有得到出错的地方。
更新
我设置log4j并完成堆栈跟踪如下。
完成堆栈跟踪

我正在尝试在列中存储一些日语内容，因此我尝试将表格整理更新为 COLLATE = ujis_japanese_ci 和 UTF-8 ，但仍然没效果。
将表及其所有字段的排序规则设置为 utf8-utf8_bin 对我来说非常有用。
答案 0 :(得分：0)
在jdbc连接中设置UTF8字符编码。这可以在hibernate.cfg.xml文件中完成，例如
<property name="connection.url">
jdbc:mysql://db-server:3306/databasename?useUnicode=true&characterEncoding=utf8
</property>
（也许只有两个选择中的一个是必要的。我没试过，我不使用日语;。）
