Capturing exceptions and sending emails using Spring AOP

Capturing exceptions and sending emails using Spring AOP involves creating an aspect that intercepts methods where exceptions may occur. Below is an example of how you can use Spring AOP to capture exceptions and send emails. In this example, I'll assume you're using Spring Boot for simplicity.

1. Setup Spring Boot Project: Set up a Spring Boot project with the necessary dependencies, including spring-boot-starter-aop and an email sending library, such as spring-boot-starter-mail.

2. Create an EmailService: Create a simple service for sending emails. You can use Spring's JavaMailSender for this purpose.

1. Create an Aspect: Create an aspect that captures exceptions and triggers the email sending.

Note: Adjust the execution expression in the @AfterThrowing annotation to match the package structure of your services.

1. Configure Spring: Ensure that the aspect and the email service are correctly configured in your Spring Boot application.

Now, when an exception occurs in any method within the specified package, the ExceptionHandlerAspect will capture it and send an email using the EmailService. Remember to replace "your.package" with the actual package name where your services are located.

Also, make sure to configure your email properties (e.g., SMTP server details) in your application.properties or application.yml file and uncomment the javaMailSender.send(message); line in the EmailService class when you are ready to send actual emails.
