Java之------单机版书店管理系统(设计思想和设计模式系列二)用户模块

书店管理系统

书店管理系统可以说是设计模式及设计思想的一个比较经典的例子。

本系列将分为多个部分讲述此输电管理系统。

书店管理系统将分为：用户、图书、进货、销售和库存五个模块，另外还有公共包、工具包和登录包，另外还有一个框架。

对于分层设计，都是表现层可以调用逻辑层，逻辑层调用数据层，数据层调用工具和公共包，方向不可打乱，必须严格按照这种模式。

本篇将做用户模块部分。

如前面所言，用户模块分为了数据层、业务逻辑层、表现层和值对象层

数据层和逻辑层又分了接口、实现和工厂三个包，里面分别存放接口、实现类和工厂类

表现层写的则是图形界面的文件

本系列所有的表现层界面全部都用面板写，因此需要有一个JFrame来承载，在这里写掉JFrame，后面的图形界面都用这个。

框架：

数据层：

1、接口

package cn.hncu.user.dao.dao;

import java.util.List;

import cn.hncu.user.vo.UserModel;
import cn.hncu.user.vo.UserQueryModel;

/**
*
* @author Lenovo
* 用户模块的数据层接口
*/

public interface UserDAO {
public boolean create(UserModel user);
public boolean delete(String uuid);
public boolean upDate(UserModel user);

public UserModel getSingle(String uuid);
public List<UserModel> getAll();
public List<UserModel> getByCondition(UserQueryModel uqm);
}

2、实现类

package cn.hncu.user.dao.impl;

import java.util.ArrayList;
import java.util.List;

import cn.hncu.user.business.factory.UserEbiFactory;
import cn.hncu.user.dao.dao.UserDAO;
import cn.hncu.utils.FileIo;
import cn.hncu.user.vo.UserModel;
import cn.hncu.user.vo.UserQueryModel;

public class UserDAOImpl implements UserDAO {
private static final String FILE_NAME="user.txt";

@Override
public boolean create(UserModel user) {
List<UserModel> list=FileIo.read(FILE_NAME);
for (UserModel u:list){

return true;
}
}
//该用户不存在
return false;
}

@Override
public List<UserModel> getAll() {
List<UserModel> list=FileIo.read(FILE_NAME);
return list;
}

@Override
public List<UserModel> getByCondition(UserQueryModel uqm) {
List<UserModel> list=getAll();
List<UserModel> results=new ArrayList<UserModel>();
for (UserModel user:list){
//反逻辑，卫条件: 外层判断用户输入是否是查询条件;内层判断该对象是否符合查询条件
if (uqm.getUuid()!=null&&uqm.getUuid().trim().length()>0){
if (!uqm.getUuid().equals(user.getUuid())){
continue;
}
}
if (uqm.getName()!=null&&uqm.getName().trim().length()>0){
if (user.getName().indexOf(uqm.getName())==-1){
continue;
}
}
if (uqm.getType()>0){
if (uqm.getType()!=user.getType()){
continue;
}
}
results.add(user);
}
return results;
}

@Override
public UserModel getSingle(String uuid) {
List<UserModel> list=FileIo.read(FILE_NAME);
for (UserModel u:list){
if (u.getUuid().equals(uuid)){
return u;
}
}
//不存在该uuid对应的用户，返回空
return null;
}

@Override
public boolean upDate(UserModel user) {
List<UserModel> list=FileIo.read(FILE_NAME);
for (int i=0;i<list.size();i++){
if (list.get(i).getUuid().equals(user.getUuid())){
list.set(i, user);
FileIo.write(list, FILE_NAME);
return true;
}
}
//不存在该用户，修改失败
return false;
}
}

3、工厂类

package cn.hncu.user.dao.factory;

import cn.hncu.user.dao.dao.UserDAO;
import cn.hncu.user.dao.impl.UserDAOImpl;

public class UserDAOFactory {
public static UserDAO getUserDAO(){
return new UserDAOImpl();
}
}

业务逻辑层：

1、接口

package cn.hncu.user.business.ebi;

import java.util.List;

import cn.hncu.user.vo.UserModel;
import cn.hncu.user.vo.UserQueryModel;

public interface UserEbi {
public boolean create(UserModel user);
public boolean delete(String uuid);
public boolean upDate(UserModel user);

public UserModel getSingle(String uuid);
public List<UserModel> getAll();
public List<UserModel> getByCondition(UserQueryModel uqm);

//此处可以在做到其他模块需要添加功能时来添加方法
public List<UserModel> getAllIn();
public UserModel getUserByName(String name);
public List<UserModel> getAllOut();
}

2、实现类

package cn.hncu.user.business.ebo;

import java.util.List;

import cn.hncu.common.UserTypeEnum;
import cn.hncu.common.UuidModelConstance;
import cn.hncu.common.uuid.dao.factory.UuidDAOFactory;
import cn.hncu.user.business.ebi.UserEbi;
import cn.hncu.user.dao.dao.UserDAO;
import cn.hncu.user.dao.factory.UserDAOFactory;
import cn.hncu.user.vo.UserModel;
import cn.hncu.user.vo.UserQueryModel;

public class UserEbo implements UserEbi {
UserDAO dao=UserDAOFactory.getUserDAO();

@Override
public boolean create(UserModel user) {
String uuid=UuidDAOFactory.getUuidDAO().getNextUuid(UuidModelConstance.USER);
user.setUuid(uuid);
return dao.create(user);
}

@Override
public boolean delete(String uuid) {
return dao.delete(uuid);
}

@Override
public List<UserModel> getAll() {
return dao.getAll();
}

@Override
public List<UserModel> getByCondition(UserQueryModel uqm) {
return dao.getByCondition(uqm);
}

@Override
public UserModel getSingle(String uuid) {
return dao.getSingle(uuid);
}

@Override
public boolean upDate(UserModel user) {
return dao.upDate(user);
}

@Override
public List<UserModel> getAllIn() {
UserQueryModel uqm=new UserQueryModel();
uqm.setType(UserTypeEnum.IN.getType());
return getByCondition(uqm);
}

@Override
public UserModel getUserByName(String name) {
List<UserModel> list=getAll();
for (UserModel user:list){
if (user.getName().equals(name)){
return user;
}
}
return null;
}

@Override
public List<UserModel> getAllOut() {
UserQueryModel uqm=new UserQueryModel();
uqm.setType(UserTypeEnum.OUT.getType());
return getByCondition(uqm);
}
}

3、工厂类

package cn.hncu.user.business.factory;

import cn.hncu.user.business.ebi.UserEbi;
import cn.hncu.user.business.ebo.UserEbo;

public class UserEbiFactory {
public static UserEbi getUserEbi(){
return new UserEbo();
}
}

值对象层：
用户类：

package cn.hncu.user.vo;

import java.io.Serializable;

import cn.hncu.common.UserTypeEnum;

public class UserModel implements Serializable{
private String uuid;
private String name;
private int type;
private String pwd;

public UserModel() {
super();
}

public String getUuid() {
return uuid;
}

public void setUuid(String uuid) {
this.uuid = uuid;
}

public String getName() {
return name;
}

public void setName(String name) {
this.name = name;
}

public int getType() {
return type;
}

public void setType(int type) {
this.type = type;
}

public String getPwd() {
return pwd;
}

public void setPwd(String pwd) {
this.pwd = pwd;
}

@Override
public int hashCode() {
final int prime = 31;
int result = 1;
result = prime * result + ((uuid == null) ? 0 : uuid.hashCode());
return result;
}

@Override
public boolean equals(Object obj) {
if (this == obj)
return true;
if (obj == null)
return false;
if (getClass() != obj.getClass())
return false;
UserModel other = (UserModel) obj;
if (uuid == null) {
if (other.uuid != null)
return false;
} else if (!uuid.equals(other.uuid))
return false;
return true;
}

@Override
public String toString() {
return uuid+","+name+","+UserTypeEnum.getNameByType(type);
}
}

用户查询类：

package cn.hncu.user.vo;

public class UserQueryModel extends UserModel{

}

表现层：

用户列表：
