What are the functions of Java Web interfaces?

The main features of Java Web interfaces include the following aspects:

1. Provide data interaction functionality: Java Web interface can be used to provide the ability to interact with data to the frontend or other systems, for example, data can be returned in JSON or XML format via the interface.
2. Implementing business logic functions: Java Web interfaces can encapsulate complex business logic, allowing the front end or other systems to utilize these functions through the interface. For example, user registration, login, and placing orders can be implemented through the interface.
3. Security authentication function of interfaces: Java Web interfaces can provide security authentication functions, for example, users’ identities and permissions can be verified through interfaces to ensure that only legitimate users can access them.
4. Function to generate interface documents: Java Web interfaces can be used to create interface documents, making it easier for other developers to view and call interfaces; for example, tools like Swagger can automatically generate interface documents.
5. Data validation and verification feature: Java Web interface can validate and verify the data received to ensure its legality and integrity, for example, using annotations, regular expressions, and other methods to validate the data.
6. Version control function for interfaces: Java Web interfaces can support version control, making it easier for future interface upgrades and iterations, such as by including a version number in the interface URL.
7. Offering interface debugging and testing capabilities: Java Web interfaces can provide debugging and testing capabilities, such as testing and debugging interfaces through interface testing tools or browsers.
8. Performance monitoring and statistical functionality for interfaces: Java Web interfaces can provide performance monitoring and statistical functionality, such as logging the number of interface calls, average response time, and monitoring interface performance in real-time.

In conclusion, the main functions of Java Web interfaces include data interaction, business logic, security authentication, interface document generation, data validation, interface version management, interface debugging and testing, interface performance monitoring, and statistics.
