Hibernate 组合查询+分页

MVC模型：Hibernate+Struts2

dao层：

public List<UserBean> searchList(UserBean uBean,int pageIndex,int pageSize);

impl层：

@SuppressWarnings( "unchecked" )
public List<UserBean> searchList(UserBean uBean,int pageIndex,int pageSize) {
Session session = HibernateUtils.getSessionFactory().openSession();
Criteria criteria = session.createCriteria(UserBean.class);
if (uBean != null) {
if (StringUtil.isNotEmpty(uBean.getName())) {
criteria.add(Restrictions.like("name", uBean.getName(),MatchMode.ANYWHERE));
}
if (StringUtil.isNotEmpty(uBean.getPwd())) {
criteria.add(Restrictions.like("pwd", uBean.getPwd(),MatchMode.ANYWHERE));
}
if (StringUtil.isNotEmpty(uBean.getType())) {
criteria.add(Restrictions.like("type", uBean.getType(),MatchMode.ANYWHERE));
}
}

criteria.addOrder(Order.asc("id"));  //根据id排序
//criteria.addOrder(Order.desc("name"));

Long totalNum = (Long)criteria.setProjection(Projections.rowCount()).uniqueResult(); //总数量
int totalPage = (int) ((totalNum + pageSize -1) / pageSize);
int startIndex = (pageIndex-1)*pageSize;

criteria.setProjection(null);
criteria.setFirstResult(startIndex);
criteria.setMaxResults(pageSize);
System.out.println("总数="+totalNum+"总页数="+totalPage);

List<UserBean> list = criteria.list();
/*Iterator iterator = list.iterator();    //测试 -- 打印返回数据
while (iterator.hasNext()) {
UserBean userBean = (UserBean) iterator.next();
System.out.println("============"+userBean.getName()+","+userBean.getCreateTime());
}*/
return list;

}

server层：

public List<UserBean> searchBeans(UserBean uBean,int pageIndex,int pageSize){
List<UserBean> list = (List<UserBean>) dao.searchList(uBean,pageIndex,pageSize);
if (list.size() > 0) {
for (int i = 0; i < list.size(); i++) {
System.out.println("-------数据信息为："+list.get(i).getId()+","+list.get(i).getName()+","+list.get(i).getCreateTime());
}
System.out.println("=====每页条目数="+pageSize);
}
return list;
}

调用：

//方法

public static String queryByUserBean() throws Exception{
UserBeanServerDaoImpl sImpl = new UserBeanServerDaoImpl();
UserBean uBean = new UserBean();
//uBean.setName("bb");
//uBean.setPwd("45");
//uBean.setType("1");
int pageIndex = 3;
int pageSize = 10;
sImpl.searchBeans(uBean,pageIndex,pageSize);
return null;
}

public static void main(String[] args) {

try {

queryByUserBean();    //测试

} catch (Exception e) {
e.printStackTrace();
}
}
