1.Research background
The design and implementation of the Servlet-based nut sales system is a research based on the current society's pursuit of healthy life and demand for nutritious food. With the improvement of people's living standards and the enhancement of health awareness, nuts are becoming more and more popular as a natural and nutritious snack. However, the traditional purchasing method has problems such as high time cost, narrow selection range, and opaque information. Therefore, the Internet-based nut sales system came into being.
By designing and implementing a Servlet-based nut sales system, we can provide users with a convenient, safe, and efficient shopping platform, allowing users to easily browse and purchase various nut products, and achieve personalized services and customized recommendations. Such a system not only meets users' needs for healthy snacks, but also promotes the development and promotion of the nut industry, which has important practical significance and application prospects.
Therefore, the design and implementation of the Servlet-based nut sales system is a positive response to current consumer needs and market trends, and is also an innovation and improvement of the traditional retail model. It is hoped that through this research, it can contribute to the development of the nut industry and the advancement of the e-commerce field.

To sum up, there have been some studies at home and abroad on the design and implementation of Servlet-based e-commerce systems. These studies mainly involve system function implementation, performance optimization, security protection, etc. However, the research on the Servlet-based nut sales system is still relatively limited, and there is still room and opportunity for further in-depth research.
5. Research content and methods
The design and implementation of the Servlet-based nut sales system mainly includes the following research contents and methods:
(1) System requirements analysis: Through the analysis of the nut sales business process and user needs, determine the functions and performance requirements that the system needs to implement. Object-oriented UML modeling method can be used for requirements analysis and system design.
(2) System architecture design: Design the system architecture, module division and data flow according to system needs and performance requirements. According to the characteristics of the Servlet container, the system is divided into multiple Servlet and JSP pages, and the system logic and data interaction functions are implemented through the MVC mode.
(3) Database design and implementation: Design reasonable database structures and SQL statements to implement operations such as storage, query, and update of data such as nut products, user information, and orders. Relational databases such as MySQL can be used to store data.
(4) User interface design and implementation: Use technologies such as HTML, CSS and JavaScript to implement the user interface of the system, including login registration, product browsing, shopping cart, order management and other functions. You can use front-end frameworks such as Bootstrap to improve user experience.

6. Feasibility analysis
The design and implementation of the nut sales system based on Servlet has certain feasibility. The following are several aspects of feasibility analysis:
(1) Technical feasibility: Servlet is an important part of Java Web development and has extensive applications and mature technical support. The Java language is cross-platform and stable, and is suitable for building medium and large-scale Web application systems. At the same time, the stability and high concurrent processing capabilities of Servlet containers (such as Tomcat) can also meet the needs of the Nut sales system.
(2) Economic feasibility: As a commercial project, the nut sales system requires an economic feasibility analysis. This system can increase revenue by selling nut products online. At the same time, development and maintenance costs are relatively low, and the use of open source Servlet containers and database technologies reduces software and hardware investments.
(3) Feasibility of user needs: Through market research and user needs analysis, determine user needs for the nut sales system. If there is a demand for nut products in the market and users are willing to accept and use the online shopping system, then the design and implementation of the nut sales system will be feasible.
(4) Risk feasibility: During the project implementation process, you may face technical risks, market risks, management risks, etc. For example, the technical aspect may encounter problems such as performance bottlenecks and security vulnerabilities; the market aspect may encounter problems such as fierce competition and changes in user needs; the management aspect may encounter problems such as improper project management and budget control. Adequate analysis of these risks and planning of countermeasures can improve the feasibility of the design and implementation of the nut sales system.
In summary, the design and implementation of a Servlet-based nut sales system has certain feasibility, but factors such as technology, economy, user needs and risks need to be comprehensively considered during the project implementation process to ensure the successful implementation and commercial feasibility of the project. sex.
7.Technical selection
This project chose to use Java Servlet as the back-end technology, combined with JSP (JavaServer Pages) as the front-end display page. The database is a relational database, such as MySQL. At the same time, front-end technologies such as HTML, CSS and JavaScript are used to achieve a user-friendly interface and interactive experience.
8.Core functions
The design and implementation of the Servlet-based nut sales system should include the following core functions:
(1) User management: including user registration, login, personal information management and other functions. Users can log in to the system through registration and manage their personal information.
(2) Product management: including the display, classification, search and other functions of nut products. Users can browse different types of nut products, select and purchase them.
(3) Shopping cart management: Users can add the nut products they are interested in to the shopping cart, and add, delete, modify, and check the items in the shopping cart.
(4) Order management: Users can view historical orders, create new orders, cancel orders and other functions. The system needs to support the order generation, payment and delivery processes.
(5) Backstage management: Administrators can manage and maintain product information, order information, and user information, including functions such as adding new products, processing orders, and user viewing.
(6) Security management: The system needs to ensure the security of user information and transaction data, and adopt appropriate encryption methods and security strategies to prevent data leaks and malicious attacks.
(7) User experience optimization: Ensure that the system interface is friendly and responsive, and provide a good user experience, including beautiful page layout and convenient interaction.
The above are the core functions of the design and implementation of the Servlet-based nut sales system. These functions can meet the needs of users to browse products and place orders, and have certain management and security capabilities. They are functions that a complete e-commerce system should have. .
