Hibernate框架的查询方式
Query查询接口
-
具体的查询代码如下
1.查询所有记录
/Query query = session.createQuery("from Customer");
List<Customer> list = query.list();
System.out.println(list);/2.条件查询:
/Query query = session.createQuery("from Customer where name = ?");
query.setString(0, "李健");
List<Customer> list = query.list();
System.out.println(list);/3.条件查询:
/Query query = session.createQuery("from Customer where name = :aaa and age = :bbb");
query.setString("aaa", "李健");
query.setInteger("bbb", 38);
List<Customer> list = query.list();
System.out.println(list);/
Criteria查询接口(做条件查询非常合适)
-
具体的查询代码如下
1.查询所有记录
/Criteria criteria = session.createCriteria(Customer.class);
List<Customer> list = criteria.list();
System.out.println(list);/2.条件查询
/Criteria criteria = session.createCriteria(Customer.class);
criteria.add(Restrictions.eq("name", "李健"));
List<Customer> list = criteria.list();
System.out.println(list);/3.条件查询
/Criteria criteria = session.createCriteria(Customer.class);
criteria.add(Restrictions.eq("name", "李健"));
criteria.add(Restrictions.eq("age", 38));
List<Customer> list = criteria.list();
System.out.println(list);/
