Hibernate多条件查询以及与java+sql 之间数据类型转换关系

方法	说明
Restrictions.eq	＝
Restrictions.allEq	利用Map来进行多个等于的限制
Restrictions.gt	＞
Restrictions.ge	＞＝
Restrictions.lt	＜
Restrictions.le	＜＝
Restrictions.between	BETWEEN
Restrictions.like	LIKE
Restrictions.in	in
Restrictions.and	and
Restrictions.or	or
Restrictions.sqlRestriction	用SQL限定查询

下面是一个例子：

@SuppressWarnings("unchecked")
public List<SSub> Select(SSub sub) {
Session session = null;
Transaction ta = null;
List<SSub> list = new ArrayList<SSub>();
try {
session = HibernateSessionFactory.getSession();
ta = session.beginTransaction();

Criteria criteria = session.createCriteria(SSub.class);
if (sub.getArriveTime() != null || !sub.getArriveTime().equals("")) {
criteria.add(Restrictions.eq("arriveTime", sub.getArriveTime()));
} else if (sub.getCreateTime() != null || !sub.getCreateTime().equals("")) {
criteria.add(Restrictions.eq("createTime", sub.getCreateTime()));
} else if (sub.getDriver() != null || !sub.getDriver().equals("")) {
criteria.add(Restrictions.eq("driver", sub.getDriver()));
} else if (sub.getId() != null || !sub.getId().equals("")) {
criteria.add(Restrictions.eq("id", sub.getId()));
} else if (sub.getKeeperId() != null || !sub.getKeeperId().equals("")) {
criteria.add(Restrictions.eq("keeperId", sub.getKeeperId()));
} else if (sub.getLicense() != null || !sub.getLicense().equals("")) {
criteria.add(Restrictions.eq("license", sub.getLicense()));
} else if (sub.getOrderId() != null || !sub.getOrderId().equals("")) {
criteria.add(Restrictions.eq("orderId", sub.getOrderId()));
} else if (sub.getSubContent() != null || !sub.getSubContent().equals("")) {
criteria.add(Restrictions.eq("subContent", sub.getSubContent()));
} else if (sub.getSubNumber() != null || !sub.getSubNumber().equals("")) {
criteria.add(Restrictions.eq("subNumber", sub.getSubNumber()));
} else if (sub.getTel() != null || !sub.getTel().equals("")) {
criteria.add(Restrictions.eq("tel", sub.getTel()));
}

ta.commit();
list = criteria.list();
} catch (Exception e) {
// TODO: handle exception
if (ta != null) {
ta.rollback();
}
e.printStackTrace();
} finally {
if (session != null) {
session.close();
}
}

return list;
}
