Crons support for Java

[adinauer]

Problem Statement

We have a crons product so we could start sending check ins from the Java SDK.

Solution Brainstorm

• Spring @scheduled
• quartz library
• investigate if there's more libs

[buckett]

We have some jobs that are effectively docker containers running in AWS ECS on a schedule. Providing an easy way to send cron data back from these jobs would also be useful.

Hello @buckett I presume you're using Java in those containers? If so, which libraries are you using? Quartz? Spring?

[buckett]

@adinauer Yeah Java, they are Spring Boot, but the triggering of the containers is AWS, so it would be nice to have the ability to start a cron monitor when the Spring application context is initialised and then complete it when it is destroyed.

Or the hook could be against the JVM instead of binding against spring.

[adinauer]

I guess that means you're not using @Scheduled or Quartz but instead the container starts on a schedule and executes some Spring application. I presume that's not a Web (WebMVC / WebFlux) application but a Spring CLI?

We'll consider the manually reporting CRONS use case when implementing.

One thing that might be tricky here is order of Sentry.init vs when to send the event.
