Spring Boot is a popular Java development framework that provides a convenient way to build efficient, scalable enterprise applications. Aspect-Oriented Programming (AOP) is an important part of the Spring Boot framework, which allows developers to improve code maintainability and reusability.
In Spring Boot, we can use @Beforeannotations to implement AOP Beforeadvice types. @BeforeAdvice indicates that the aspect logic will be executed before the target method is executed. This is a commonly used AOP notification type, often used in logging, security checks, and more.
The following explains in detail how to use annotations in Spring Boot @Before, and provides a complete example and code to demonstrate its usage. In the example, we will create a simple user authentication function and use AOP to record the log before the user logs in.
