对于建立图书馆管理系统的项目模拟经验
对于建立图书馆管理系统的项目模拟经验
此次项目模拟，是在Windows环境下施行的。主要的工具为java程序。
-
首先下载eclipse并在其中选择java应用程序
-
然后需要在Windows上搭建java的环境变量（具体参照WIN10下，Jdk的环境变量
配置 link.） -
在Java中新建一个java计划并命名“图书馆管理计划”，然后建包和类
第一步就是要写入配置文件
- 首先配置图书馆的选择方法：
package com.zxyt.bean;
public class ChooseBean {
private int s_id,z_id,l_id,t_id;
private String s_time;
public int getS_id() {
return s_id;
}
public void setS_id(int sId) {
s_id = sId;
}
public int getZ_id() {
return z_id;
}
public void setZ_id(int zId) {
z_id = zId;
}
public String getS_time() {
return s_time;
}
public void setS_time(String sTime) {
s_time = sTime;
}
public void setL_id(int l_id) {
this.l_id = l_id;
}
public int getL_id() {
return l_id;
}
public void setT_id(int t_id) {
this.t_id = t_id;
}
public int getT_id() {
return t_id;
}
}
- 然后进行图书馆管理方法的配置：
package com.zxyt.bean;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.List;
public class LibraryBean {
private int l_id,l_num,l_status;
private String l_name,l_address,l_b_time_str,l_e_time_str;
private Date l_b_time,l_e_time;
private List tpb;
public int getL_id() {
return l_id;
}
public void setL_id(int lId) {
l_id = lId;
}
public int getL_num() {
return l_num;
}
public void setL_num(int lNum) {
l_num = lNum;
}
public int getL_status() {
return l_status;
}
public void setL_status(int lStatus) {
l_status = lStatus;
}
public String getL_name() {
return l_name;
}
public void setL_name(String lName) {
l_name = lName;
}
public String getL_address() {
return l_address;
}
public void setL_address(String lAddress) {
l_address = lAddress;
}
public String getL_b_time_str() {
return l_b_time_str;
}
public void setL_b_time_str(String lBTimeStr) {
SimpleDateFormat sDateFormat=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
System.out.println(lBTimeStr);
try {
l_b_time=sDateFormat.parse(lBTimeStr);
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
l_b_time_str = lBTimeStr;
}
public String getL_e_time_str() {
return l_e_time_str;
}
public void setL_e_time_str(String lETimeStr) {
SimpleDateFormat sDateFormat=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
try {
l_e_time=sDateFormat.parse(lETimeStr);
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
l_e_time_str = lETimeStr;
}
public Date getL_b_time() {
return l_b_time;
}
public void setL_b_time(Date lBTime) {
l_b_time = lBTime;
}
public Date getL_e_time() {
return l_e_time;
}
public void setL_e_time(Date lETime) {
l_e_time = lETime;
}
public List getTpb() {
return tpb;
}
public void setTpb(List tpb) {
this.tpb = tpb;
}
}
- 然后是学生文件的配置：
package com.zxyt.bean;
public class StudentBean {
private String s_name,s_pwd;
private int s_id;
public String getS_name() {
return s_name;
}
public void setS_name(String sName) {
s_name = sName;
}
public String getS_pwd() {
return s_pwd;
}
public void setS_pwd(String sPwd) {
s_pwd = sPwd;
}
public int getS_id() {
return s_id;
}
public void setS_id(int sId) {
s_id = sId;
}
}
- 还有就是在时间文件上的配置：
package com.zxyt.bean;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
public class TimePartBean {
private int t_id,l_id;
private String t_b_time_str,t_e_time_str;
private Date t_b_time,t_e_time;
public int getT_id() {
return t_id;
}
public void setT_id(int tId) {
t_id = tId;
}
public int getL_id() {
return l_id;
}
public void setL_id(int lId) {
l_id = lId;
}
public String getT_b_time_str() {
return t_b_time_str;
}
public void setT_b_time_str(String tBTimeStr) {
SimpleDateFormat sDateFormat=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
try {
t_b_time=sDateFormat.parse(tBTimeStr);
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
t_b_time_str = tBTimeStr;
}
public String getT_e_time_str() {
return t_e_time_str;
}
public void setT_e_time_str(String tETimeStr) {
SimpleDateFormat sDateFormat=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
try {
t_e_time=sDateFormat.parse(tETimeStr);
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
t_e_time_str = tETimeStr;
}
public Date getT_b_time() {
return t_b_time;
}
public void setT_b_time(Date tBTime) {
t_b_time = tBTime;
}
public Date getT_e_time() {
return t_e_time;
}
public void setT_e_time(Date tETime) {
t_e_time = tETime;
}
}
- 最后一个配置文件就是要写入座位的选择机制：
package com.zxyt.bean;
public class ZuoweiBean {
private int z_id,l_id,z_status;
public int getZ_id() {
return z_id;
}
public void setZ_id(int zId) {
z_id = zId;
}
public int getL_id() {
return l_id;
}
public void setL_id(int lId) {
l_id = lId;
}
public int getZ_status() {
return z_status;
}
public void setZ_status(int zStatus) {
z_status = zStatus;
}
}
第二步是搞定service服务文件
- 先写入图书馆的服务文件：
package com.zxyt.service;
import java.text.SimpleDateFormat;
import java.util.ArrayList;
import java.util.Date;
import java.util.List;
import java.util.Scanner;
import com.zxyt.bean.LibraryBean;
import com.zxyt.bean.TimePartBean;
public class LibraryService {

String l_e_time = sc.nextLine();
LibraryBean lib = new LibraryBean();
lib.setL_b_time_str(l_b_time);
lib.setL_e_time_str(l_e_time);
lib.setL_address(l_address);
lib.setL_id(l_id);
lib.setL_name(l_name);
lib.setL_num(l_num);
lib.setL_status(0);
List part_list=time_parts(lib);
lib.setTpb(part_list);
list.add(lib);
/*for(LibraryBean bean:list){
System.out.println(bean.getL_id()+"--"+bean.getL_b_time_str()+"---"+bean.getL_e_time_str());

}
/**

long ts_b = lib.getL_b_time().getTime();

int count = (int) Math.ceil((double)(ts_e-ts_b)/(num*60*1000));
for(int i=0;i=ts_e){
date_end = new Date(ts_e);

}else{

}
String t_e_time_str = simpleDateFormat.format(date_end)+"";
timebean.setT_e_time_str(t_e_time_str);
ts_b+=(num*60*1000);
list.add(timebean);
if(flag==1){
break;
}
}
return list;
}
public String show_menu() {
// TODO Auto-generated method stub
System.out.println("青选择要对管理员进行的操作：");
System.out.println("【A】 添加 \t 【B】开放/禁用");
System.out.println("【C】 返回");
Scanner sc = new Scanner(System.in);
String input = sc.next().toLowerCase();
return input;
}
public void open() {
// TODO Auto-generated method stub
while(true){

int l_id = sc.nextInt();
int flag=0;
for(LibraryBean bean:list){

System.out.println("禁用成功！！！");
}else{

System.out.println("启用成功！！！");
}
flag=1;
break;
}
}
if(flag==0){
System.out.println("没有找到该图书馆，图书馆编号错误！！！");
}
}
}
/**
* 选择图书馆
* @return 图书馆对象
*/
public LibraryBean chooseLibrary() {
// TODO Auto-generated method stub
System.out.println("图书馆列表：");
System.out.println("图书馆编号\t 图书馆地址\t 图书馆容量\t 图书馆开放时间\t 图书馆关闭时间\t 状态\t");
for(LibraryBean lib:list){

}
System.out.println(lib.getL_id()+"\t "+lib.getL_address()+"\t "+lib.getL_num()+"\t "+lib.getL_b_time_str()+"\t "+lib.getL_e_time_str()+"\t "+status_name+"\t");
}
LibraryBean ret_lib=null;
while(true){

return ret_lib;
}
public TimePartBean choosePartTime(LibraryBean libBean) {
// TODO Auto-generated method stub

}
}
if(flag==0){
System.out.println("请输入正确的时间段编号！！！");
}else{
break;
}
}
return ret_lib;
}
}
- 然后管理员服务文件：
package com.zxyt.service;
import java.util.ArrayList;
import java.util.List;
import java.util.Scanner;
import com.zxyt.bean.ManagerBean;
public class ManagerService {

System.out.println("【C】 删除 \t 【D】返回");
Scanner sc = new Scanner(System.in);
String input = sc.next().toLowerCase();
return input;
}
/**

return 1;
}
/**

}
- 学生服务文件：

- 座位选择服务文件：

}
}
return ret_bean;
}
}
最后一步就是要进行程序的测试啦
- 管理员测试文件：
package com.zxyt.test;
import java.util.Scanner;
public class Menu {
public String show_stu_menu() {
System.out.println("欢迎进入学生选座系统");
System.out.println("【A】 选定座位 \t 【B】取消座位");
System.out.println("【C】 我的座位 \t 【D】退出");
Scanner sc = new Scanner(System.in);
String input = sc.next().toLowerCase();
return input;
}
/**
* 管理员管理菜单
* @return 选择的操作
*/
public String show_mana_menu() {
System.out.println("欢迎进入管理管理系统");
System.out.println("【A】 管理员管理 \t 【B】学生管理");
