Spring cron expression for every day 1:01:am

🌼 Mastering Spring Cron Expressions for Perfect Scheduling 🌼

Are you struggling to schedule your code execution at a fixed time using a Spring cron expression? 😫 Don't worry, we've got you covered! In this blog post, we'll walk you through the common issues that might arise when setting up a cron expression for running code every day at 1:01 AM and provide easy solutions that will ensure your code runs flawlessly. So, let's dive in! 💪

The Mysterious Cron Expression Syntax

Before we jump into troubleshooting, let's understand the syntax of a cron expression. A cron expression consists of six fields separated by spaces, representing the following values:

second minute hour day-of-month month day-of-week

Here, we are interested in executing our code every day at 1:01 AM, so our cron expression should look like this:

0 1 1 * * *

Now that we know the basic syntax, let's address the specific error you encountered and find an easy solution for it. 😉

Common Issue: Incorrect Syntax for Day of the Month

In the provided code snippet, you used a question mark (?) in place of the day of the month field. However, the question mark is used only for the day of the week field, not for the day of the month field. This is what prevented your code from firing up as expected. 😕

Easy Solution: Specify the Day of the Month

To fix this issue, replace the question mark in the cron expression with an asterisk (*), which represents all possible values. This will ensure that your code is executed every day of the month. Here's the corrected cron expression for your requirement:

@Scheduled(cron = "0 1 1 * * *")
public void resetCache() {
    // ...
}

Time to Take Action!

With the corrected cron expression, your code should now execute every day at 1:01 AM without any issues. It's time to celebrate that victory! 🎉 But before you go, we have a call-to-action for you.
