毕业设计(十一)---后台用户管理(1)之-用户信息分页显示[hibernateTemplate分页]

后台管理使用的网上找的模板，把头和侧边导航写成一个jsp 文件， 在每一个新的管理页面上进行引用。网上模板很多，。不详细说

用户信息显示其实就是 点击左侧的 "用户管理" 显示用户信息.

过程:

一:struts.xml 配置action

<action name="manageruser" class="ActionManagerUser" >
			<result name="success" >/admin/managerUser.jsp</result>
		</action>

二action调用manager方法

@Component("ActionManagerUser")
@Scope("prototype")
public class ActionManagerUser extends ActionSupport {
	private Manager manager;
	private PageBean pageBean;
	private int page;
	private String username;

	//此处省略 get  set 方法

	@Resource
	public void setManager(Manager manager) {
		this.manager = manager;
	}

	// 查找所有用户
	@Override
	public String execute() throws Exception {

		if(username==null){
			this.pageBean = manager.queryUsersForPage(7, page);	
		}else
		{
			this.pageBean = manager.queryUsersForPageByUsername(8, page,username);
		}
		

		return SUCCESS;
	}

}

三:manager调用分页查找方法:

public PageBean<Users> queryUsersForPage(int pageSize, int page) {
		// TODO Auto-generated method stub
		return userDao.queryUsersForPage(pageSize, page);
	}

四:userDaoImpl方法  【最重要】

@Override
	public int userNums() {
		List list = hibernateTemplate.find("select count(*) from Users");
		int num = Integer.parseInt(list.get(0).toString());
		return num;
	}

	
	
	@Override
	public PageBean<Users> queryUsersForPage(int pageSize, int page) {
		// 获取所以的记录数
		int allRow = this.userNums();
		// 获得总页数
		int totalPage = PageBean.countTotalPage(pageSize, allRow);
		// 计算当前页
		final int currentPage = PageBean.coutCurrentPage(page);
		// 当前要显示的起始数
		final int offset = PageBean.countOffset(pageSize, currentPage);
		// 获取要显示的页面信息 offset要显示页面的第一个的所以
		List<Users> list = this.getListForPage("from Users", offset, pageSize);
		// System.out.println(list);
		PageBean<Users> pagebean = new PageBean();
		pagebean.setPagesize(pageSize);
		pagebean.setCurrentPage(currentPage);
		pagebean.setAllRow(allRow);
		pagebean.setTotalPage(totalPage);
		pagebean.setList(list);
		pagebean.init();
		return pagebean;
	}

	
	
	public List<Users> getListForPage(final String hql, final int offset, final int length){
		List list = hibernateTemplate.executeFind(new HibernateCallback(){
			public Object doInHibernate(Session session) throws HibernateException,SQLException{
				Query query = session.createQuery(hql);
				query.setFirstResult(offset);
				query.setMaxResults(length);
				List<Users> list = query.list();
				return list;
			}
		});
		return list;
	}

五：jsp页面显示代码

<table width="100%" border="0" cellpadding="0" cellspacing="1"
				bgcolor="#a8c7ce">
