android ormlite登录注册的例子(7)

 
public class UsersEntity implements Serializable 
{ 
    private static final long serialVersionUID = -6582623980712135028L; 
    @DatabaseField(generatedId=true) 
    private int id; 
    @DatabaseField 
    private String username; 
    @DatabaseField 
    private String password; 
    public UsersEntity(){} 
    public UsersEntity(int id, String username, String password) 
    { 
        super(); 
        this.id = id; 
        this.username = username; 
        this.password = password; 
    } 
    public int getId() 
    { 
        return id; 
    } 
    public String getPassword() 
    { 
        return password; 
    } 
    public String getUsername() 
    { 
        return username; 
    } 
    public void setId(int id) 
    { 
        this.id = id; 
    } 
    public void setPassword(String password) 
    { 
        this.password = password; 
    } 
    public void setUsername(String username) 
    { 
        this.username = username; 
    } 
} 
 
 
再是操作数据库的类，我按照mvc的模式把操作数据库的类单独分离开了
 
 
Java代码 
package com.cng.dao; 
 
import java.sql.SQLException; 
import java.util.HashMap; 
import java.util.List; 
import java.util.Map; 
 
import com.cng.model.UsersEntity; 
import com.j256.ormlite.dao.Dao; 
 
public class UsersDao  
{ 
     
    public List<UsersEntity> findUser(Dao<UsersEntity, Integer> userdao,String username,String password) throws SQLException 
    { 
        Dao<UsersEntity, Integer> userDao = userdao;
