spring-aop

This is a simple spring boot application that implements Spring AOP

What is Spring AOP

• Aspect Oriented Programming (AOP) compliments OOPs in the sense that it also provides modularity.
• AOP breaks the program logic into distinct parts (called concerns). It is used to increase modularity by cross-cutting concerns.

Spring AOP can be used in three different manners.

1. By Spring1.2 Old style (dtd based) (also supported in Spring3)
2. By AspectJ annotation-style
3. By Spring XML configuration-style(schema-based)

But the most widely used approach is Spring AspectJ Annotation Style. This example implements using AspectJ annotation-style.

Dependency to support Spring AOP

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-aop</artifactId>
</dependency>

Steps to create Spring AOP Application

1. Create Spring Boot Project
2. Add Spring AOP maven dependency

4. Write methods on which you want to execute advices
5. Run the application and watch the console
