Hibernate使用hql语句查询

public class TestQueryAll {

// 使用hql语句查询语句
// hql模糊查询
String searchKey = "小";
Student us = new Student();
us.setNickName("%" + searchKey + "%");
String hql = "from Student where nickName like :nickName";//注意这里写的都是Student类里面的
Query query = session.createQuery(hql);
query.setProperties(us);
List<Student> userList = query.list();
for (Student u : userList) {
System.out.println(u.getNickName() + "," + u.getAge() + ","
+ sdf.format(u.getBirthday()));
}

}
