Hi, Spring fans! Welcome to another installment of This Week in Spring! It's November 10th, 2020, as I write this and I, for one, can not believe that we're closer to 2021 than we are to 2019 at this point. That's insane. Time has absolutely rocketed by in some senses and stood utterly still in others. Odd year, this one.

I hope you're all doing well! I'm at the Reactive Summit today (virtually, of course). This afternoon I was on a wonderful panel with all sorts of folks from around the ecosystem. And soon, around 17:30 or so, if memory serves, I'll be speaking about RSocket and its use in…

• RowMapper and ResultSetExtractor as beans.
• Improved performance for entities.
• Support of Oracles temporal types.

If you regularly listen to A Bootiful Podcast, you might have heard about the improvements we made to Spring Framework’s cron support. Cron expressions are mostly used in Spring applications through the @Scheduled annotation. In Spring 5.3, we introduced the CronExpression class, which represents — you guessed it — a cron expression.

CronExpression replaces CronSequenceGenerator, which is based on java.util.Calendar and which has several known issues that none of the Spring team members felt comfortable solving. Introducing a new type allowed us to use the superior java.time APIs, solve the…
