java 获取 系统当前时间 并以一定格式放入数据库

pojo类设计为Date类型,MySQL数据库的表字段为datetime,就是
User u = new User();
u.setCreateDate(此处为Date类型);

1.修改User.hbm.xml
<property name="createdDate" type="date">
    <column name="CREATED_DATE" length="7" not-null="true" />
</property>
为
<property name="createdDate" column ="CREATED_DATE">
</property>

2.

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
Date d = new Date();
u.setCreateDate(sdf.parse(sdf.format(d)));
