JSF的服务器端分页的实现

相信对JSF有一定了解的童鞋，都知道怎么用dataGrid显示数据，一般情况我都是用的都是客户端分页，闲来无事按照例子写了个服务器端分页，话不多说，贴代码：

@Inject(value = "employeeSpringService")
private IEmployeeService es;


@Bind(id = "grid", attribute = "value")
	private GridDataProvider dataProvider = new CachedPagedDataProviderAdapter(
			new CachedPagedDataProvider() {
	@Override
	public Object getData(int start, int limit) {
		     return es.limitQuery(start, limit).toArray();
	            }
	@Override
	public int getTotalCount() {
	            List list=es.getTotal();
	            return ((Long)list.get(0)).intValue();
	  }

});

 

public List<Employee> limitQuery(int start,int limit) {
	logger.debug("finding the queried Employee instances");
        try {
        	DetachedCriteria dc=DetachedCriteria.forClass(Employee.class);
	List<Employee> results = (List<Employee>) getHibernateTemplate().findByCriteria(dc, start, limit);
	logger.debug("find queried successful, result size: " + results.size());
            return results;
        } catch (RuntimeException re) {
            logger.error("find queried failed", re);
            throw re;
        }
	}
	
public List getTotal() {
	logger.debug("finding the queried Employee instances");
        try {
        	 List  results =getHibernateTemplate().find("select count(*) FROM Employee");
                logger.debug("find queried successful, result size: " + results.size());
            return results;
        } catch (RuntimeException re) {
            logger.error("find queried failed", re);
            throw re;
        }
	}

 主要就是getHibernateTemplate().findByCriteria()方法。。。
