ssh实现用户登录验证，注册用户添加用户，查询所有用户信息

<pre name="code" class="java">package dao;import java.util.List;import entity.Userinfo;public class UserinfoDao extends DaoSupport {/** * 登陆验证 */public boolean validate(Userinfo user){boolean flag=false;List<Userinfo> list=this.findByProperty(Userinfo.class, "uname", user.getUname());if(list!=null&&list.size()>0){Userinfo u=list.get(0);if(u.getUpass().equals(user.getUpass())){flag= true;} }return flag;}/** * 获取所有用户 */public List<Userinfo> getAllUser(){return this.findAll(Userinfo.class);}/** * 添加员工信息 */public void addUser(Userinfo user){this.save(user);}}
