1.1 Research background
In recent years, with the development of society, the flow of people staying in hotels has continued to increase, and the number of hotels has also increased. As a result, the amount of information in the management of hotel rooms has also continued to increase exponentially. Therefore, the traditional hotel information management method More and more problems are exposed, which consumes manpower and is inefficient. At this time, hotels are in urgent need of various systems that can enable hotel staff to manage the huge amount of information faster, more conveniently and more accurately.
Today, when Internet technology is ubiquitous, people's lives are inseparable from computers, using them for work, study and even shopping. For example, when people go on a business trip or travel abroad, they usually choose to book a room online in advance according to their own needs, which greatly saves the time of finding a room. At this time, the hotel needs a corresponding guest room reservation management system to manage guest rooms and reservation information.
For hotels with a large number of rooms, it is particularly important to use a hotel system to manage room information and reservation information. This system not only facilitates customers to make reservations, but also facilitates staff, greatly saving time. Therefore, it is necessary to develop a hotel accommodation reservation system.
1.2 Development significance
Hotel Accommodation Reservation System In terms of expression, it carries out information management of a large amount of hotel room information to facilitate the processing of customers' check-in and check-out. It also provides room reservation functions. Provide convenience to customers. Its functions are mainly manifested in the following aspects:
(1) Improve the management effect of the hotel
The hotel accommodation reservation system can save a lot of manpower and material resources, increase the hotel's service items, improve the hotel's service level, and reduce hotel management loopholes, thereby reducing the overall management cost and improving the hotel's economic effect. The complete reservation function can effectively prevent the phenomenon of unavailable rooms for rent or rebooking of rooms, thereby increasing the occupancy rate of rooms. Publish hotel event announcement information to customers in a timely manner to increase room revenue.
(2) Improve service quality
The computer itself processes information very quickly, which can greatly save guests waiting time when checking in, checking out, and paying. The comprehensive booking function allows users to quickly browse all hotel room information, allowing users to have a comprehensive understanding of the hotel and choose satisfactory rooms according to their own needs. Overall customer satisfaction.
(3) Improve work efficiency
Information management can greatly improve the speed and accuracy of business operations. The use of a database system to save data avoids the inefficiency of filling out paper orders, and its strict data checking can effectively avoid errors caused by careless manual operations. 1.3SSM framework
SSM is SpringMVC+Spring+Mybatis. These three frameworks have their own unique advantages, so combining them can create strong sparks. Designers can create Web applications without spending a lot of effort, and this program also has the characteristics of clear hierarchy, upgrade and update operations that do not affect normal use, and allows multiple uses. This composite framework forms a system with a complete structure, powerful functions and good structure: SpringMVC separates each module, Spring makes development more flexible and convenient, and uses Mybatis to allow developers to directly manipulate objects. Each level has a detailed division of labor and realizes each level. The decoupling between them makes the code more flexible and streamlined. This framework allows programmers to avoid individual errors during the development period that will lead to overall destruction, and to respond to new customer demands for the product in the later stages.
1.4 Paper structure and chapter arrangement
The paper will be organized hierarchically. In addition to the abstract, acknowledgments, and literature references, the main text will also analyze the website requirements, describe the general design and implemented functions, and finally list some debugging records. The main structure of the paper is as follows:
Chapter One Introduction. The first chapter mainly introduces the background of the project research, the current situation of system development and the research content and main work of this article.
Chapter 2: System requirements analysis. Chapter 2 mainly conducts demand analysis from the aspects of users and functions of the system.

Chapter 5: System Testing. Chapter 5 mainly tests some interfaces of the system and tests the main functions.
2 Analysis of hotel accommodation reservation system
System analysis is a prerequisite for developing a project. Through system analysis, the basic needs of the main users of the system can be well understood, and this is also the reason for the development of the project. Then, a feasibility analysis is performed on the system development, which usually includes technical feasibility, economic feasibility, etc. The feasibility analysis is also an analysis from the overall perspective of the project. Then the specific requirements of the project are analyzed. The analysis method is generally implemented through the user's use case diagram. The following is a detailed introduction.
2.1 Feasibility analysis
Most of the tools used in the project are currently popular open source and free, so in the early stage of development, the funds used for the project will be greatly reduced, and the development of the software will not be affected by funds during the project startup period, so It is still economically feasible. Try to meet the needs of users with the least amount of money. Save money on labor costs and equipment costs. We will go further and further on the road of paperlessness and high efficiency.
So there is no problem with economic feasibility.
(2) Operational feasibility:
The design of this project refers to several cases of website development under this mode, analyzes their operation interfaces, and combines many cases to highlight people-oriented simplified operations, so people with basic computer knowledge can operate this project.
Therefore, there is no problem with operational feasibility.
(3) Technical feasibility:
Technical feasibility refers to the feasibility of building a framework, as well as the system's adaptability to technological upgrading when better technologies emerge, and the development time and cost ratio.
Existing Java technology can cater to the construction of all e-commerce systems. When developing this hotel accommodation reservation system, I used Java+MYSQL to run the overall program.
In summary, there is no problem with the technical feasibility.
(4) Legal feasibility:
From a developer's perspective, Java and MYSQL are open source and free online, and there will be no legal disputes regarding intellectual property rights.
From a user perspective, as long as contraband is no longer sold on the system, treaties and agreements are made with the system, and illegal payments are eliminated.
In summary, there is no problem with the legal feasibility.
The business process uses some specific symbols and lines to demonstrate the user's process when using the system. When performing system analysis, the business process can help developers better understand the business, discover errors, and improve the system.
After the user successfully logs in to the system can add data. The number of added data is specific and generated by the system. The user cannot arbitrarily Fill in, except for the number, other added information is filled in by the user. The filled-in information is verified by the system. If the verification is legal, it will show that the data has been added successfully. Otherwise, the addition has not been successful. Figure2 -1 shows the process when adding data.
Figure 2-1 Data addition flow chart
2.2.2 Data modification process
The process of data modification is similar to the process of data addition described above, as shown in Figure 2-2.
Figure 2-2 Data modification flow chart
If there is some useless data in the system, the relevant managers still a>These data can be deleted. Figure2-3 is the flow chart for data deletion.

3.1 System structure design
This hotel accommodation reservation system is architecturally divided into three layers: presentation layer (UI), business logic layer (BLL) and data layer (DL).
Figure 3-1 System architecture design diagram of hotel accommodation reservation system
Presentation layer (UI): Also known as the UI layer, it mainly completes the UI interaction function of the hotel accommodation reservation system. A good UI can improve the user experience and enhance the user's comfort when using the hotel accommodation reservation system. The UI interface design must also adapt to different versions of hotel accommodation reservation systems and different size resolutions to achieve good compatibility. The UI interaction function requirements are reasonable, and users must obtain consistent interaction results when performing interactive operations. This requires the presentation layer to be well connected with the business logic layer.
Business Logic Layer (BLL): Mainly completes the data processing function of this hotel accommodation reservation system. The data transmitted by the user from the presentation layer is processed by the business logic layer and delivered to the data layer. The data read by the system from the data layer is processed by the business logic layer and delivered to the presentation layer.
Data layer (DL): Since the data of this hotel accommodation reservation system is placed in the mysql database on the server side, the part that belongs to the service layer can be directly integrated into the business logic layer, so there is only a database in the data layer, which mainly completes this task. Data storage and management functions of hotel accommodation reservation system.
3.2 System function module design

The detailed design and implementation of the hotel accommodation reservation system is mainly based on the previous demand analysis of the hotel accommodation reservation system and the overall design of the hotel accommodation reservation system to design the page and implement the business logic. This article mainly introduces the hotel accommodation reservation system interface implementation and business logic implementation.
4.1User function module
4.1.1 Previous stage interface
When entering the hotel accommodation reservation system, the first thing that comes into view is the navigation bar of the system. Below is the carousel chart and system content. The main interface is shown in Figure 4-1 below.
Figure 4-1 Front page interface diagram
4.1.2 User registration interface
Those who are not formal members of the hotel reservation system can register online. If you do not have an account in the hotel reservation system, add "Register" and fill in your account number + password + confirmation password + nickname + email + mobile phone. After waiting for the number and then clicking the "Register" button, it will first verify whether there is any empty data entered, verify again whether the password and confirmation password are the same, and finally verify whether the entered account name is the same as the account name already registered in the database table. Only After all verifications are complete, the membership registration can be successful. The user registration interface is shown in Figure 4-2 below.
Figure 4-2 Front-end user registration interface diagram
The key code of registration logic is as follows.
* register
* @return
*/
@PostMapping("register")
public Map<String, Object> signUp(HttpServletRequest request) throws IOException {
//Query user
Map<String, String> query = new HashMap<>();
Map<String,Object> map = service.readBody(request.getReader());
query.put("username",String.valueOf(map.get("username")));
List list = service.selectBaseList(service.select(query, new HashMap<>()));
if (list.size()>0){
return error(30000, "User already exists");
}
map.put("password",service.encryption(String.valueOf(map.get("password"))));
service.insert(map);
return success(1);
}
public Map<String,Object> readBody(BufferedReader reader){
BufferedReader br = null;
StringBuilder sb = new StringBuilder("");
try{
br = reader;
String str;
while ((str = br.readLine()) != null){
sb.append(str);
}
br.close();
String json = sb.toString();
return JSONObject.parseObject(json, Map.class);
}catch (IOException e){
e.printStackTrace();
}finally{
if (null != br){
try{
br.close();
}catch (IOException e){
e.printStackTrace();
}
}
}
return null;

5系统测试
系统开发到了最后一个阶段那就是系统测试，系统测试对软件的开发其实是非常有必要的。因为没什么系统一经开发出来就可能会尽善尽美，再厉害的系统开发工程师也会在系统开发的时候出现纰漏，系统测试能够较好的改正一些bug，为后期系统的维护性提供很好的支持。通过系统测试，开发人员也可以建立自己对系统的信心，为后期的系统版本的跟新提供支持。
系统测试包括：用户登录功能测试、酒店信息展示功能测试、酒店信息添加、酒店信息搜索、密码修改功能测试，如表5-1、5-2、5-3、5-4、5-5所示：

通过编写酒店住宿预定系统的测试用例，已经检测完毕用户登录模块、酒店信息查看模块、酒店信息添加模块、酒店信息搜索模块、密码修改功能测试，通过这5大模块为酒店住宿预定系统的后期推广运营提供了强力的技术支撑。
至此，酒店住宿预定系统已经结束，在开发前做了许多的准备，在本系统的设计和开发过程中阅览和学习了许多文献资料，从中我也收获了很多宝贵的方法和设计思路，对系统的开发也起到了很重要的作用，系统的开发技术选用的都是自己比较熟悉的，比如Web、Java技术、MYSQL，这些技术都是在以前的学习中学到了，其中许多的设计思路和方法都是在以前不断地学习中摸索出来的经验，其实对于我们来说工作量还是比较大的，但是正是由于之前的积累与准备，才能顺利的完成这个项目，由此看来，积累经验跟做好准备是十分重要的事情。
当然在该系统的设计与实现的过程中也离不开老师以及同学们的帮助，正是因为他们的指导与帮助，我才能够成功的在预期内完成了这个系统。同时在这个过程当中我也收获了很多东西，此系统也有需要改进的地方，但是由于专业知识的浅薄，并不能做到十分完美，希望以后有机会可以让其真正的投入到使用之中。

致 谢
逝者如斯夫，不舍昼夜。转眼间，大学生会员活便已经接近尾声，人面对着离别与结束，总是充满着不舍与茫然，我亦如此，仍记得那年秋天，我迫不及待的提前一天到了学校，面对学校巍峨的大门，我心里充满了期待：这里，就是我新生活的起点吗？那天，阳光明媚，学校的欢迎仪式很热烈，我面对着一个个对着我微笑的同学，仿佛一缕缕阳光透过胸口照进了我心里，同时，在那天我认识可爱的室友，我们携手共同度过了这难忘的两年。如今，我望着这篇论文的致谢，不禁又要问自己：现在，我们就要说再见了吗？
感慨莫名，不知所言。遥想当初刚来学校的时候，心里总是想着工科学校会过于板正，会缺乏一些柔情，当时心里甚至有一点点排斥，但是随着我对学校的慢慢认识与了解，我才认识到了她的美丽，她的柔情，并且慢慢的喜欢上了这个校园，但是时间太快了，快到我还没有好好体会她的美丽便要离开了，但是她带给我的回忆，永远不会离开我，也许真正离开那天我的眼里会满含泪水，我不是因为难过，我只是想将她的样子映在我的泪水里，刻在我的心里。最后，感谢我的老师们，是你们教授了我们知识与做人的道理；感谢我的室友们，是你们陪伴了我如此之久；感谢每位关心与支持我的人。
少年，追风赶月莫停留，平荒尽处是春山。
