[b]1.添加[/b]
public int insertNewOneUser(UserVo user) {
Session session = sessionFactory.openSession();
Transaction tx = null;
try {
tx = session.beginTransaction();
session.save(user);
tx.commit();
} catch (Exception e) {
tx.rollback();
e.printStackTrace();
} finally {
session.close();
}
return 0;
}
[b]2.修改[/b]
public int updateUser(UserVo user) {
Session session = sessionFactory.openSession();
Transaction tx = null;
try {
tx = session.beginTransaction();
session.update(user);
tx.commit();
} catch (Exception e) {
tx.rollback();
e.printStackTrace();
} finally {
session.close();
}
return 0;
}
[b]3.删除[/b]
public int deleteUser(UserVo user) {
Session session = sessionFactory.openSession();
Transaction tx = null;
try {
tx = session.beginTransaction();
session.delete(user);
tx.commit();
} catch (Exception e) {
tx.rollback();
e.printStackTrace();
} finally {
session.close();
}
return 0;
}
[b]4.获得结果集[/b]
public UserVo selectUserFromId(int id) {
Session session = sessionFactory.openSession();
Transaction tx = null;
try {
tx = session.beginTransaction();
Query query = session.createQuery("from UserVo where id = :id");
query.setInteger("id", id);
return (UserVo) query.list().get(0);
} catch (Exception e) {
tx.rollback();
e.printStackTrace();
} finally {
session.close();
}
return null;
}
