Answer 1

对，把你的SQL语句贴出来。com.mysql.jdbc.exceptions.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '.GUESTBOOK guestbook_ where guestbook_.ID=1000076' at line 1

Answer 2

应该怎么写，谢谢。我的HQL语句这样写的from Guestbook order by id desc

Answer 3

from Guestbook as gb order by gb.id desc

Answer 4

at com.njcit.guest.dao.hibernate.GuestBookDaoHibernate.save(GuestBookDaoHibernate.java:34)
at com.njcit.guest.service.impl.GuestbookManagerImpl.save(GuestbookManagerImpl.java:34)把这两行代码贴出来..很显然,不是说你这个SQL语句报错.你的肯定有where 语句..
你看他打印的.where guestbook_.ID=1000076' 

Answer 5

错误中出现的where字句了并且肯定是你的sql有问题。
