Cron Jobs

In modern backend development, asynchronous processing plays a crucial role in improving performance and responsiveness. Spring Boot provides a powerful mechanism for executing tasks asynchronously using the @Async annotation. This blog post will explore how to use @Async, its configuration, best practices, and some real-world use cases. What is @Async in Spring Boot? The @Async annotation in Spring allows methods to run asynchronously in a separate thread, enabling non-blocking execution. This is particularly useful when handling long-running tasks, such as sending emails, making API calls, or processing large amounts of data without blocking the main thread. ...

Imagine this: Your Java application is set up to run scheduled tasks at specific intervals, but there’s a catch—during maintenance mode, you want to temporarily disable these jobs. Modifying each job individually to check for a maintenance flag can be tedious, repetitive, and error-prone. This is where Aspect-Oriented Programming (AOP) comes to the rescue. In this post, we’ll dive into Aspect-Oriented Programming in Java and explore how you can use it to conditionally run cron jobs based on a property, such as a “maintenance mode” flag. Let’s start by understanding AOP and then dissect a practical example. ...
