相当相当隐蔽的错误 org.hibernate.hql.ast.QuerySyntaxException: unexpected token


今天周末,被头儿过来改bug
其中一个在hql查询的时候报org.hibernate.hql.ast.QuerySyntaxException: unexpected token: ApplyInfo near line 1, column 23这样的错误,貌似看起来hibernate不认识ApplyInfo这个映射持久类,但是这个类非常确定的是已经映射了,而且在别处用的非常正常。郁闷,找啊找
在网上找org.hibernate.hql.ast.QuerySyntaxException: unexpected token的错误有
1、持久类写错了,要不就是写成了数据库表名
2、hibernate3.0不支持select中嵌套查询,据说from中也不行,只支持where中嵌套查询,好像3.1支持了select中嵌套
3、sql语句中字段是用了保留关键字

然后就是我发现的这个隐蔽错误了
发现的from后的空格是一个全角的空格,半角 空格,全角 空格。距离比一样啊,原来就看出from后面的空格大了,还以为是两个空格呢。

隐蔽,太隐蔽了。
