Java EE and Java Spring: The Spring Framework is an open source application framework and inversion of control container for the Java platform. The framework's core features can be used by any Java application, while providing extensions for building web applications on top of the Java EE (Enterprise Edition) platform.
Java Spring MVC: Model–view–controller is a software design pattern commonly used for developing user interfaces that divides the related program logic into three interconnected elements which mainly focus on separating internal representations of information from the ways information is presented to and accepted from the user
Mybaits: it is is a Java persistence framework that couples objects with stored procedures or SQL statements using an XML descriptor or annotations.
MySql: MySQL is a open-source, medium weight database software, which has stand-alone clients that allow users to interact directly with a MySQL database using SQL statement.
Redis: Redis (Remote Dictionary Server)is an in-memory data structure store, used as a distributed, in-memory key–value database, cache and message broker, with optional durability. which supports different kinds of abstract data structures, such as strings, lists, maps, sets, sorted sets, HyperLogLogs, bitmaps, streams, and spatial indexes.
Layui: Layui is a front-end UI framework which could provide a plenty of functionalities such as tables, layout, buttons and so on.
Register: User could register by entering their email, username and password, and verification code. After registration, the user will be automatically logged in and store their logging information in the cookies of the browser and also the in the local storage, sessions in the server will also simultaneously store them accordingly.
Verification code: A CheckCodeUtil class is implemented to automatically generate verification code image by drawing four different characters and blocking lines randomly in Java server, this functionality is adopted in order to reduce malign registration by scripts or robots, thus enhance the security of the server.
Login: User could login after their registration, the cookies will be stored in browser while next time browser will automatically login for them. To be notice that there are many pages only available for login users, such as buyTicket.jsp, buySeat.jsp and so on.
Logout: After login, user could just click the top right button to logout, which would delete the cookies and local storage in the browser and sessions in the server.
Show movies: In the main page, the latest eight films, the top nine movies for the box office and eight upcoming films were shown, using the font-end UI framework Layui, and we also drew inspiration from the design of Maoyan movies. The data is selected from database and sent to browser.
Movies: User could select the movie mode, then directly type in movie names to search for the movies.
Stars: User could select the star mode, then type in movie stars names to search for the movies that actor or actress in them.
Theater： User could select the theater mode, then directly type in theater names to search for the available theater.
View Order information: After login, user could go to their user page and chose My Order to browse their orders of tickets, they could also apply for Print, scanning QR code for information and refund. According to the user's ID, the order information of the user is searched from the database and displayed in the browser. When the user clicks QR code, the server will generate a QR code including the information about the movie and return it to the user.
QR code: This functionality can convert a string into a QR code. By using the package called zxing, the server could generate QR code according to the giving string.
QR ticket: The information about the order will be converted into a string and the string is put into QR generator.
Then the QR code is generated which includes the information about the order.
After scanning the QR code by the phone: Print tickets:
Download APK: There is a QR code including the address about the APK for Android. And there also is a web page that APK can be downloaded.
The system will recommend movies based on the user's ticket records. If the user has never bought a ticket, it will recommend the movie with the highest score.
The system gives different weights to movie types, directors, actors, and ratings, then calculates user preferences and recommends movies. For instance, if the user bought the movie “Hi, Mom” which Shen Teng is in this movie, and this movie is a comedy type.
So, the movie “Crazy Alien” which is also a comedy and Shen Teng play a main role in it, will be recommend the first, along with other comedy films.

If the user cannot complete the selection within the specified time, he will be forced to exit. In addition, after the user selects the seat, the seat will be locked in a period of time. During this period, other users in the front cannot select this seat. First, an initialized seat table is passed from the back end, which contains the seat information that has been selected. Users are restricted to gray seats.
The countdown function is completed by JS. The seat lock is implemented by Zedis. When a user selects seats, a hash value will be passed to Zedis, which will time the hash. During the time, these seats cannot be selected by other users.
Buy tickets (Payment): This page also has a timer. If the payment is not completed before the end of the timer, it will be forced to exit. And the details of this order are shown here.

Zedis is a module that we implemented to emulate Redis as a hash-stored remote server, which used to store the queuing information to solve the concurrent problem when multiple users booking the same seat. This module used TCP Server-Client model to handle user’s request.
For the database, we choose MySql which is a medium weight database software, and there are 8 tables in total (comment, hall, cinema, movie, orderinfo, user, schedule, card), there are a variety of filed types along with different length limitations, such as varchar (20), varchar (150), varchar (30), varchar (50), datetime, int, bigint, double.
The field of password in user table for datable model is encrypted generate password through 64 Base Encoder method, while checking password function is also defined, by carry on identical encryption process to handle requested raw password, then comparing to values stored in database, which could avoid storage of cleartext password. When view functions need to check password, they could just simply call the check function. By this means, password stored in database is encrypted, which means no cleartext passwords are stored in database.
To avoid malign attackers that use SQL statement to hack the server, PrepareStatement is introduced to replace all susceptible code, which use “?” question mark as placeholder for the search SQL statement, and dynamically generate the query request, secure the system.
We use Github as our version control tools with two branch in total, 111 commits along with Wiki Pages.
Multi-city, multi-theater movie booking options.
