1. 在实际开发中需要在hbm文件中使用的type属性值是指定的类型。那
么指定的类型一般的是基于hibernate的类型。
2. 当然在实际过程中也可以在hbm文件中指定java类型。
public class DataType { private long id; private boolean tag; private Date createDate; private char vip; private Timestamp logTime; private byte[] description; …. }
<hibernate-mapping> <class name="cn.itcast.hibernate.datatype.DataType" table="datatype"> <id name="id" column="id" type="long"> <generator class="increment"></generator> </id> <property name="tag" column="tag" type="boolean"></property> <property name="createDate" column="createDate" type="date"></property> <property name="vip" column="vip" type="character"></property> <property name="logTime" column="logTime" type="timestamp"></property> <property name="description" column="description" type="binary"></property> </class> </hibernate-mapping>
流类型 FileInputStream in = new FileInputStream(new File("测试文档.txt")); int length = in.available(); byte[] b = new byte[length]; in.read(b); 时间戳类型 new Timestamp(System.currentTimeMillis()) 查询的排序 session.createQuery("from DataType as d order by d.id asc"); 分页 query.setFirstResult(2); query.setMaxResults(2); 方法比较 list()/iterator()的区别
