Ø[/b] Hibernate[/b]是一个对象/关系(O/R) 框架，它允许你将一个Java对象同一个表关联。
[/b]Ø[/b] [/b]要确保对象的id属性的getter是当前类的第一个方法，否则生成的JSP的页面可能会有一个脚本错误
[/b]Ø[/b] [/b]注意：所有的 @hibernate.* tag必须放在你的POJO的getter的Javadoc中
[/b]Ø[/b] [/b]如果你想更改列的长度, 更改@hibernate.property标记的length属性。如果你希望它是一个必填的字段(NOT NULL)，那么你要添加not-null="true"。
[/b]Ø[/b] [/b]添加column属性的唯一原因是:表的列名和对象的属性名字不一致。如果他们一致，就不需要添加column属性。[引用][/b]
