请帮我注释一下分页查询的代码---先谢了！
public List<Object> queryList(final String hql,final Integer showNumber,final Integer beginNumber) {
List list = null;
try {
list = this.getHibernateTemplate().executeFind(
new HibernateCallback() {
public Object doInHibernate(Session session)
throws HibernateException, SQLException {
Query query = session.createQuery(hql);
query.setFirstResult(beginNumber);
query.setMaxResults(showNumber);
List list = query.list();
return list;
}
});
} catch (Exception e) {
e.printStackTrace();
}
return list;
}

------解决方案--------------------
public List<Object> queryList(final String hql,final Integer showNumber,final Integer beginNumber) {
List list = null;
try {
list = this.getHibernateTemplate().executeFind(
new HibernateCallback() {
public Object doInHibernate(Session session)
throws HibernateException, SQLException {
//执行sql
Query query = session.createQuery(hql);
//本次查询的起始条数
query.setFirstResult(beginNumber);
//最后条数
query.setMaxResults(showNumber);
List list = query.list();
return list;
}
});
} catch (Exception e) {
e.printStackTrace();
}
return list;
}

Java code

public List<Object> queryList(final String hql,final Integer showNumber,final Integer beginNumber) {
    List list = null;    
    try {
        list = this.getHibernateTemplate().executeFind(    //以下实例化HibernateCallback对象，匿名内部类，类实现或重写了doInHibernate方法
            new HibernateCallback() {
                public Object doInHibernate(Session session) throws HibernateException, SQLException {
                    Query query = session.createQuery(hql);    //根据hql语句，生成查询对象
                    query.setFirstResult(beginNumber);        //设置查询对象从哪行数据起查询
                    query.setMaxResults(showNumber);        //设置查询对象返回结果的最大个数。
                    List list = query.list();                //执行查询
                    return list;
                }
        });
    } catch (Exception e) {
        e.printStackTrace();
    }
    return list;
}
