测试代码:
Session session=HibernateSessionFactory.getSession();
Transaction tran=session.beginTransaction();
Member member=new Member();
member.setAddress("address");
member.setHomePage("http://www.zgdsc.cn");
member.setIsEnabled("true");
member.setMemberId(new Integer(1));
member.setLastLoginDate("2008-12-12 12:25:25.0");
session.save(member);
tran.commit();

Answer 2

导入的Date类型有sql和util两种,可能是这个问题吧.

Answer 3

 member.setLastLoginDate("2008-12-12 12:25:25.0");
你的属性里是timestamp，这里传的是字符串，所以类型不匹配

Answer 4

 <property name="buildDate" type="time"> 
            <column name="buildDate" length="23" /> 
        </property> 
        <property name="portrait" type="java.lang.String"> 
            <column name="portrait" length="50" /> 
        </property> 
        <property name="lastLoginDate" type="time"> 
            <column name="lastLoginDate" length="23" /> 
        </property> 试下。

Answer 5

你传个 new java.util.Date() 就行了 杂要那么传

Answer 6

2008-12-12 12:25:25.0...这是字符串,错误提示告诉你是错误的参数类型...
你要不就把这个字符串先转成timestamp,再弄吧..
