實體類User

package com.lwl.pojo;

public class User {

   private Integer id;
   private String username;


    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    @Override
    public String toString() {
        return "User{" +
                "id=" + id +
                ", username='" + username + '\'' +
                '}';
    }
}

DAO層

package com.lwl.pojo.dao;

import com.lwl.pojo.User;
import org.dom4j.DocumentException;

import java.beans.PropertyVetoException;
import java.util.List;

public interface IUserDao {


    //查詢所有用戶
    public List<User> findAll() throws Exception;

    //根據條件進行查詢
    public User findByCondition(User user) throws Exception;

    //修改用戶
    void update(User user) throws Exception;

    //修改用戶
    void creat(User user) throws Exception;

    //刪除
    void delete(User user) throws Exception;



}
