To activate @Aspect in AEM, you need to first create a new Java class that implements the org.aspectj.lang.annotation.Aspect interface. This class should contain the advice methods that you want to run before or after certain join points in your AEM application.
Next, you need to configure the aspect in your AEM project by adding the appropriate annotations to your aspect class. You can use annotations such as @Before, @After, @Around, etc., to define when and how your advice methods should be executed.
Finally, you need to configure AEM to load and activate your aspect at runtime. This can be done by registering your aspect class as an OSGi component in AEM, and ensuring that it is properly included in your AEM project's bundle.
By following these steps, you can activate @Aspect in AEM and start using aspect-oriented programming techniques to enhance the behavior of your AEM application.

What is the behavior of @aspect when AEM is restarted?
When Adobe Experience Manager (AEM) is restarted, the behavior of an @aspect will depend on how the aspect is managed and implemented within the AEM system.
- If the @aspect is implemented using OSGi services or Sling models, it will be bound and activated when the AEM instance starts up. This means that the aspect will be available for use immediately after the restart.
- If the @aspect is a custom implementation that relies on specific configurations or components that are loaded or initialized during AEM startup, the aspect may not function correctly until those configurations or components are reloaded or reinitialized after the restart.
In general, aspects in AEM should be designed to gracefully handle restarts and ensure that they are properly initialized and bound when the system comes back online. It is important to test the behavior of aspects after an AEM restart to ensure that they function as expected.
How to optimize the performance of @aspects in AEM?
To optimize the performance of @aspects in Adobe Experience Manager (AEM), consider the following best practices:
- Use @PostConstruct and @PreDestroy annotations: Use @PostConstruct annotation to perform initialization tasks and @PreDestroy annotation to perform cleanup tasks. This helps in efficient resource management and improves performance.
- Limit the use of aspect-oriented programming: While AOP can be a powerful tool for modularizing cross-cutting concerns, excessive use of aspects can impact performance negatively. Only apply aspects where necessary and avoid over-engineering.
- Use pointcut expressions efficiently: Use pointcut expressions to define where an aspect should be applied. Be specific in defining the target methods or classes to avoid unnecessary overhead on performance.
- Optimize advice execution: Carefully design the advice logic to ensure that it is executing efficiently. Avoid expensive computations or operations within the advice to improve performance.
- Minimize the number of aspects: Keep the number of aspects to a minimum to reduce complexity and improve performance. Consolidate similar aspects or refactor them to reduce the overall number.
- Monitor and tune performance: Regularly monitor the performance of aspects in AEM using profiling tools or AEM's built-in monitoring features. Identify bottlenecks or areas for optimization and tune the aspects accordingly.
- Test performance impact: Conduct performance testing to evaluate the impact of aspects on the overall system performance. Make adjustments as needed to optimize performance without sacrificing functionality.
By following these best practices, you can optimize the performance of @aspects in AEM and ensure efficient and reliable operation of your application.
How to monitor the performance of @aspects in AEM?
To monitor the performance of aspects in AEM, you can follow these steps:
- Utilize the AEM Logs: Check the logs in AEM to see if there are any errors or warnings related to aspects. Look for any performance-related issues or lagging that may be affecting the aspects.
- Use the AEM Query Performance Optimization Tool: This tool allows you to analyze the performance of queries in AEM and identify any areas where aspects may be slowing down performance. You can optimize queries to improve the overall performance of aspects.
- Monitor the AEM Configuration Manager: Check the configuration settings for aspects in AEM and make sure they are properly configured for optimal performance. You can adjust these settings as needed to improve the performance of aspects.
- Utilize AEM Health Check Tools: AEM provides various health check tools that allow you to monitor the overall health and performance of your AEM instance. Use these tools to check the performance of aspects and identify any areas for improvement.
- Use Performance Monitoring Tools: Consider using third-party performance monitoring tools to track the performance of aspects in AEM. These tools can provide detailed insights into the performance of aspects and help you identify any issues that need to be addressed.
By following these steps, you can effectively monitor the performance of aspects in AEM and ensure they are functioning optimally.
