1. 2 Development significance
With the development of global informatization, people 's life pace is getting faster and faster, and people pay more and more attention to the timeliness of information. Traditional media based on traditional propaganda methods have long been unable to meet users' needs for information acquisition and convenience. Therefore, the new student registration system has gradually become the focus of users ' attention. First of all, the real-time and convenient nature of obtaining information online is much higher than that of traditional media. Once the system is online, no matter where in the world the user is, as long as they can connect to the Internet, they can get the information they want as soon as possible.
In the past, the reporting and management of college students and freshmen were all done manually by staff. This method is not only timely but also inconvenient when searching and changing. With the advancement of science, the maturity of technology, and the rapid development of computer informatization, society has also gained a profound understanding that computers are very powerful. Computers have entered various fields of the development of human society and play a very important role.
The application of computer technology in modern management has made computers an important tool for users to apply modern technology. It can effectively solve the problem of convenient and comprehensive acquisition of information and improve efficiency.
1.3 Research status
In many developed countries abroad, the software industry has already been fully popularized. However, our country's economy has continued to develop, and foreign informatization construction has been continuously introduced, which has enabled the domestic software industry to continue to develop, make progress through exploration, and finally achieve some results. my country's software industry Ushering in rapid development, more software systems have been developed, gradually changing the way people live and work. However, with regard to the construction of informatization, compared with many developed countries, due to the backwardness of informatization and lack of funds, the development of the freshman registration system in our country is still relatively backward. Therefore, we must continue to work hard to explore and strive to develop a A practical information-based new student registration system to realize the informatization of new student registration . Therefore, this topic takes freshman registration as an example, and the purpose is to develop a practical freshman registration system .
The development of the new student registration system was completed using Java language, Springboot framework , Mysql and other technologies to jointly complete the development of the system, realizing the informatization of the new student registration system , allowing students to experience a better new student registration system , and administrator management The operation will be more convenient to achieve the goal.

Chapter 2 Introduction to Development Technology
The key technologies and architecture of this system , Java language, B/S structure, Springboot framework and Mysql database, are the key development technologies of this system. The overall system, database, functional modules, system pages and system programs are designed in detail. research and planning.
2.1 java language
The Java language is a completely object-oriented programming language. The idea of object-oriented programming language is to regard objectively existing things as a class of objects with states and behaviors, and then use abstract methods to find the common states and behaviors of the same class of objects to form a model - a class. Class is the core of Java programming language and the basic abstract unit of Java language. All things in the world are objects, and they can be abstracted into classes with states and behaviors. The main characteristics of the Java language are:
a) The Java language is typically object-oriented. It provides classes, which in turn provide object models. By using inheritance and polymorphic methods, code reuse can be achieved.
b) Java language is safe. The biggest problem to be solved in the contemporary network environment is security. Java has internal security measures to ensure the safety and integrity of the program.
c) The operation of Java language is platform independent. Java programs can run on any system as long as the Java operating system is installed.
d) Java language is multi-threaded.
e) Java language has memory management. Java can automatically manage memory, making good use of system resources and reducing waste .
2.2 B/S architecture
The B/S system can be used through a computer with Internet access. Its biggest advantage is that it does not require the installation of special software. First, the browser sends a request to the server, and then the server processes the request and returns the information to the browser . There is no need to access and calculate the data again. It only needs to be responsible for displaying the data to reduce the requirements . If the client is like a "skinny person", the server will become more and more "fat" . Compared with the C/S architecture, the biggest difference between the B/S architecture and the C/S architecture is that the application software of the B/S system uses a web browser as a platform to interact with users , while C/S requires the development of dedicated applications .

2. 3 Introduction to MySQL
In software projects, by operating the database of data, it can be ensured that its security, independence and data consistency are provided, and access to the data is provided by the system, thus effectively reducing the time for programmers to develop applications.
MySQL can support multi-threading, which can easily use system resources and improve running speed. It also provides odbc, jdbc and tcp/ip to connect to MySQL in various forms; it is lacking in functionality and small in scale, but it is enough for this system.
Because the source code of MySQL is open to the outside world, anyone can download it through the corresponding method and modify it according to personalized needs. MySQL is valued due to its speed, reliability, and adaptability.
Although MySQL may not be very powerful, many people are aware of this database due to its open source and wide spread.
This technology is an open source application framework for the Java platform, and its purpose is to simplify the initial construction and development process of Sping. By default, many framework usage methods are configured, and Jar packages are automatically loaded, in order to allow users to run spring applications as quickly as possible.
The main advantages of SpinrgBoot are:
- Provides a faster and broader entry experience for all spring development;
- Zero configuration;
- Integrated the configuration of a large number of commonly used third-party libraries;
4. Provide ready features. Today, all developers in the Java field are using SpinrgBoot, and it has gradually become a leader in the development field .
Chapter 3 System Analysis
3.1 Feasibility analysis
For a complete system, feasibility analysis is a must, because it is related to the survival of the system. Analyze the significance of development and whether this system can be used to supplement the deficiencies in the offline freshman reporting system model and solve them. deficiencies, etc., through this system, not only can the workload be continuously reduced, but also the efficiency of work and management can be made higher. Therefore, developing this system can achieve greater significance and value. After the system is completed, whether it can achieve the expected results must be analyzed through feasibility. After the analysis, it is decided whether to develop the system. In the development and design of the new student registration system , a feasibility analysis was conducted on the technical, economic and operational aspects .
3.1.1Technical feasibility _
The Java language was selected for the development of this system . The purpose of its research is to create visible information for web pages. With the continuous development and innovation of mobile Internet technology, Java has become the Web standard of the next generation Internet. Therefore, Mysql was chosen for the backend design . The database is mainly used to establish and maintain information. The backend development requirements should have the advantages of complete functions and easy operation, while the backend database requirements are to be able to establish and maintain the unity and integrity of data information.
3.1. 2 Operational feasibility
Now with the rapid development of science and technology, computers have already entered people's daily lives, and people's working environment does not have as many requirements as before, which has greatly improved people's work efficiency. The diversity of operations has also become higher. Therefore, computerization and intelligence of management are inevitable trends brought about by social development. Various intelligent software emerge in endlessly. Different software can meet different needs of users and improve work efficiency. This system not only has a simple and clear interface, but also adopts a visual interface. Users can modify, delete, add and other operations on relevant information by simply using the mouse and keyboard. Because the operation of this system is very simple and easy to get started, it only takes a short time for people who use the system for the first time to get started. It can be seen that this system is operationally feasible.
3.1. 3 Economic feasibility
The new student registration system based on Java only requires an ordinary computer to develop the system software, and its cost is very low. In addition, as a graduation project, the development cost is basically negligible, and the putting into use of the system software can effectively save human resources and management resources. The freshman registration system is completely economically feasible .
3.2 Performance requirements analysis
Let’s analyze the performance of the system one by one from the aspects of (function, operation, interface, security);
1. Analyze whether the functions of the system are complete: The functions of the system can be designed corresponding to the original codes and algorithms, and personal information can be introduced in detail in the form of tables and text to ensure that the functions are complete;
2. Analyze whether the system is running smoothly: Each function of the system has a data relationship and response code. The physical data of the system is analyzed and displayed through demand analysis and feasibility analysis to ensure smooth operation;
3. Analyze the interface design of the system: The way to process and analyze the software in the system is carried out by different codes; thus making the interface easy to operate.
4. Analyze the security of the system: This way, each role will have different corresponding information. You must use your own account and password to log in to the system. If the account and password are incorrect, the login will naturally fail . After successfully logging in, you can operate your own information, but you cannot view the information of other people's accounts. This naturally ensures the security of the system.
