Hibernate 与 MySql 数据库关键字冲突You have an error in your SQL syntax; check the manual
诶..说来,实在是惭愧.一个错误.害惨我了..搞了几个小时.. 今天使用JSF+Spring+Hibernate框架 和mysql数据库做项目时,发生一个异常..我万万没有想到..居然是关键字,所引起的..
具体Hibernate生成的sql语句如下:
Hibernate:
insert
into
pl_roles_acl
(ROLE_NAME, SORT_ORDER, RESOURCE_NAME, READ, CREATE, UPDATE
, DELETE, EXECUTE)
values
(?, ?, ?, ?, ?, ?, ?, ?)
2011-01-05 15:55:27,296 org.hibernate.util.JDBCExceptionReporter - SQL Error: 1064, SQLState: 42000
2011-01-05 15:55:27,296 org.hibernate.util.JDBCExceptionReporter - 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 'READ, CREATE, UPDATE, DELETE, EXECUTE) values ('SAP', 4, 'userMaintenance', 0, 0' at line 1

做项目的时候, 朋友们, 千万要避免mysql或者其他数据有关键字的问题..
如果有关键字 ..
也可以,在所对应的 .XXX.Hibernate.hbm.xml 文件里面改 ,具体操作如下:
看红色的标记,. 在关键字中 加 "[]" .或者 加, \" \" 或者 '"READ" '..都行
<!-- 在角色对象中拿到所有的权限;-->
