Hibernate: org.hibernate.exception.SQLGrammarException: could not insert: 错误_javaPie的博客-程序员宝宝_org.hibernate.exception.sqlgrammarexception: could

    最近在学习Java Web，今天刚接触Hibernate。学习的书籍是《轻量级Java EE企业应用实战（第3版）》。书中367页5.2.2中给予的Hibernate例子中的代码运行有以下错误：

    搜了很久，出现这种错误主要是这种情况：MySql关键字冲突。表名和列名不能是MySql关键字。MySql关键字如下：

    不错，我的代码中并没有关键字。

    在搜索了很久之后，终于在http://bbs.csdn.net/topics/390475056找到答案。

    “数据库方言用的是MySQLInnoDBDialect，这个要表存在才能用，是改变表的结构的。改用MySQLDialect；一下是区别：
　　MySQLDialect：mysql默认存储引擎为InnoDB，需创建新表（表名不存在）
　　MySQLInnoDBDialect：mysql默认存储引擎为InnoDB，需更改表结构（表名存在）”

    将代码中MySQLInnoDBDialect改为MySQLDialect即可（我没有创建表）。
