Spring AOP Advice Types Explained | @Before, @After, @Around | Spring Boot Full Course #23

In this video, we implement Spring AOP advice types and understand exactly when each advice executes around a target method. We begin by creating a Spring AOP aspect, writing a pointcut expression, and understanding how Spring creates a proxy around the original target object. Then, we implement and compare all five major advice types: @Before @AfterReturning @AfterThrowing @After @Around You will also learn: Target object vs proxy object Advice, pointcut expression and target method Using JoinPoint to access method details and arguments Using ProceedingJoinPoint inside @Around What proceed() actually does Success and exception flow for every advice type Reading returned values and thrown exceptions Modifying method arguments using proceed(modifiedArguments) Modifying or wrapping the returned value Measuring method execution time What happens when proceed() is not called Why calling proceed() multiple times can be dangerous How to choose the correct advice type in real applications By the end of this video, you will understand not only how to write Spring AOP advice, but also how the complete proxy and advice execution flow works internally.
