我在页面删除一条数据,有时候可以删除吊,有时候就出现空白页面,后台报数据删除失败,请问什么原因?
代码是
Action:
int i = 0;
ProcessForm pf = (ProcessForm)form;
MyProjectDAO dao = new MyProjectDAO();
Customer customer = new Customer();
BeanUtils.copyProperties(customer,pf);
i=dao.addRecored(customer);
if(i==1){
System.out.println("插入记录成功");
request.getRequestDispatcher("/process.do?param=defaultFind").forward(request, response);
}
else{
System.out.println("插入失败");
}
return null;
}
}

你给的代码貌似是添加的,但你的问题是删除,搞不懂了
