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">
