What is the IoC in spring?
Spring IoC is the mechanism to achieve loose-coupling between Objects dependencies. To achieve loose coupling and dynamic binding of the objects at runtime, objects dependencies are injected by other assembler objects. … Spring IoC container provides us different ways to decouple the object dependencies.
What is spring Autowiring?
Autowiring feature of spring framework enables you to inject the object dependency implicitly. It internally uses setter or constructor injection. Autowiring can’t be used to inject primitive and string values.
What is required annotation in spring?
The @Required annotation in spring is a method-level annotation applied to the setter method of a bean property and thus making the setter-injection mandatory. This annotation indicates that the required bean property must be injected with a value at the configuration time.
What is PointCut and JoinPoint in spring?
JoinPoint: Joinpoint are points in your program execution where flow of execution got changed like Exception catching, Calling other method. PointCut: PointCut are basically those Joinpoints where you can put your advice(or call aspect). So basically PointCuts are the subset of JoinPoints.
What is the full form of advice?

What is a bean in spring?

How do I enable AOP in spring?
For using Spring AOP in Spring beans, we need to do the following: Declare AOP namespace like xmlns:aop=”https://www.springframework.org/schema/aop” Add aop:aspectj-autoproxy element to enable Spring AspectJ support with auto proxy at runtime. Configure Aspect classes as other Spring beans.

What is spring bean life cycle?
A “Spring bean” is just a Spring managed instantiation of a Java class. The Spring IoC container is responsible for instantiating, initializing, and wiring beans. The container also manages the life cycle of beans. Spring provides several ways through which you can tap into the bean lifecycle.
What is ProceedingJoinPoint in spring?
ProceedingJoinPoint in spring is used for the method which advices to method in AOP. ProceedingJoinPoint is used as an argument of the methods which hints for before, after, after throwing and around. ProceedingJoinPoint has the methods like getKind, getTarget, proceed etc.
How does AOP work in spring?
In the Spring Framework, an AOP proxy will be a JDK dynamic proxy or a CGLIB proxy. Weaving: linking aspects with other application types or objects to create an advised object. This can be done at compile time (using the AspectJ compiler, for example), load time, or at runtime.
What does @required annotation mean?
Advertisements. The @Required annotation applies to bean property setter methods and it indicates that the affected bean property must be populated in XML configuration file at configuration time. Otherwise, the container throws a BeanInitializationException exception.
What is advice in spring?
Advice: Action taken by an aspect at a particular join point. Different types of advice include “around,” “before” and “after” advice. Advice types are discussed below. Many AOP frameworks, including Spring, model an advice as an interceptor, maintaining a chain of interceptors “around” the join point.
What is ContextStoppedEvent?
ContextStoppedEvent. This event is published when the ApplicationContext is stopped using the stop() method on the ConfigurableApplicationContext interface. You can do required housekeep work after receiving this event.
What is Spring AOP used for?
Spring AOP enables Aspect-Oriented Programming in spring applications. In AOP, aspects enable the modularization of concerns such as transaction management, logging or security that cut across multiple types and objects (often termed crosscutting concerns).
What is Spring AOP example?
One of the key components of Spring Framework is the Aspect oriented programming (AOP) framework. Spring AOP module provides interceptors to intercept an application. … For example, when a method is executed, you can add extra functionality before or after the method execution.
What is a PointCut in spring?
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.
