1、数据实体Bean
public class Tempimplements Serializable
{
private java.lang.Long id;
private Blob object; //用于存放对象的Blob
private java.lang.Long userId;
private java.util.Date appendDate;
}
2、hbm影射
TEMP_SEQ
3、save方法
public void saveTemp( ) throws IOException, ClassNotFoundException, SQLException
{
Temp temp = new Temp();
temp.setUserId(new Long(1));
temp.setAppendDate(new Date());
ByteArrayOutputStream outputstr = new ByteArrayOutputStream();
ObjectOutputStream objOutStr = new ObjectOutputStream( outputstr );
objOutStr.writeObject( contract ); //contract为要保存的对象；
BlobImpl blob = new BlobImpl(outputstr.toByteArray());
temp.setObject( blob );
saveTemp(temp);//将Temp持久化到数据库；
}
4、get方法
public void etTempList() throws IOException, ClassNotFoundException, SQLException
{
List Templist = getTempList( userId);
if( contractTemplist.size() != 0 )
{
Temp temp = ( Temp )Templist.get(0);
ObjectInputStream instr = new ObjectInputStream(temp.getObject().getBinaryStream());
Contract contract = ( Contract )instr.readObject();
}
}
