What is a bean in spring?
In Spring, the objects that form the backbone of your application and that are managed by the Spring IoC container are called beans. A bean is an object that is instantiated, assembled, and otherwise managed by a Spring IoC container. Otherwise, a bean is simply one of many objects in your application.
Where do we use AOP in spring?
Where to use Spring Aspect Oriented Programming. Some of the cases where AOP is frequently used: To provide declarative enterprise services. For example, as declarative transaction management. It allows users for implementing custom aspects.
What is PointCut in Spring AOP?
PointCut is a set of one or more JoinPoint where an advice should be executed. You can specify PointCuts using expressions or patterns as we will see in our AOP examples. In Spring, PointCut helps to use specific JoinPoints to apply the advice.
How does AOP work?
2 Answers. Your understanding is right. Spring AOP is proxy-based. Spring uses either JDK proxies (preferred wheneven the proxied target implements at least one interface) or CGLIB proxies (if the target object does not implement any interfaces) to create the proxy for a given target bean.
What is the use of AOP?
AOP (aspect-oriented programming) is a programming style that can be adopted to define certain policies that in turn are used to define and manage the cross-cutting concerns in an application. In essence, it’s a programming paradigm that enables your application to be adaptable to changes.

How does spring boot handle exceptions?

What is the key element in AOP?
