改章节是一篇关于查询生成的帖子
这是抛出来的提示信息:
type Exception report
message could not execute query; nested exception is org.hibernate.exception.SQLGrammarException: could not execute query
description The server encountered an internal error that prevented it from fulfilling this request.
exception
org.springframework.dao.InvalidDataAccessResourceUsageException: could not execute query; nested exception is org.hibernate.exception.SQLGrammarException: could not execute query org.springframework.orm.hibernate3.SessionFactoryUtils.convertHibernateAccessException(SessionFactoryUtils.java:613) org.springframework.orm.hibernate3.HibernateAccessor.convertHibernateAccessException(HibernateAccessor.java:412)
提示是没法进行查询,我们可以把他生成的sql 复制在sql editer中去运行下,你就会发现错误了
很有可能是因为表名 或者字段名 是sql的关键字引发的。
在bean的hbm.xml 文件中给字段 或者 表名加上回避符就能够了。[表名]
附上一段我报错的配置文件,修复准确的:

文章结束给大家分享下程序员的一些笑话语录: 某程序员对书法十分感兴趣,退休后决定在这方面有所建树。花重金购买了上等的文房四宝。一日突生雅兴,一番磨墨拟纸,并点上了上好的檀香,颇有王羲之风 范,又具颜真卿气势,定神片刻,泼墨挥毫,郑重地写下一行字:hello world.
