Getting Started with Spring Boot AOP

Introduction :

Aspect-Oriented Programming (AOP) is a powerful technique to modularize cross-cutting concerns in your application. Spring Boot provides excellent support for AOP, allowing you to separate concerns like logging, security, transaction management, and more from the main business logic of your application.

In this tutorial, we’ll walk through the basics of setting up and using AOP in a Spring Boot application with a practical example.


  • Basic understanding of Spring Boot and Spring Framework concepts.
  • JDK 8 or higher installed on your system.
  • Maven or Gradle installed for managing dependencies (we’ll use Maven in this tutorial).
  • IDE of your choice (IntelliJ IDEA, Eclipse, etc.).

Step 1: Create a new Spring Boot Project
We’ll start by creating a new Spring Boot project. You can do this either manually or using Spring Initializr. For simplicity, let’s use Spring Initializr.

  1. Go to
  2. Fill in the necessary details such as Group, Artifact, and dependencies. For this tutorial, choose the following:
  • Group: com.example
  • Artifact: spring-boot-aop-example
  • Dependencies: Select “Spring Web” and “Spring AOP”.
  1. Click on “Generate” to download the project zip file.

Step 2: Set up the Project in your IDE
Once you’ve downloaded the project, unzip it and open it in your preferred IDE.

Step 3: Create a Simple Service
Let’s create a simple service with a method that we’ll apply our aspect to.

Create a new Java class SimpleService in the package com.example.springbootaopexample.service:

Step 4: Create an Aspect
Now, let’s create our aspect. We’ll create a simple aspect that logs a message before and after the execution of the doSomething() method.

Create a new Java class LoggingAspect in the package com.example.springbootaopexample.aspect:

Step 5: Run the Application
Now, let’s run our Spring Boot application and see the aspect in action.

mvn spring-boot:run

You should see the following output in the console:

Before method execution...
Doing something...
After method execution...

Congratulations! You’ve successfully created a Spring Boot application that utilizes AOP to log messages before and after the execution of a method.

In this tutorial, you’ve learned the basics of using AOP in a Spring Boot application. AOP helps in keeping your codebase clean and modular by separating cross-cutting concerns. You can extend this example by adding more complex pointcuts and advices to handle various cross-cutting concerns in your application.
