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);

}

}
