Agent-skills-standard spring-boot-scheduling

Configure scheduled tasks and distributed locking with ShedLock in Spring Boot. Use when implementing @Scheduled tasks or distributed locking with ShedLock in Spring Boot. (triggers: **/*Scheduler.java, **/*Job.java, scheduled, shedlock, cron)

Spring Boot Scheduling Standards

Priority: P0

Configure Scheduled Tasks

ThreadPool: ALWAYS configure dedicated
```
TaskScheduler
```
(default 1 thread). Enable with
```
@EnableScheduling
```
annotation.
Async: Keep
```
@Scheduled
```
methods light; offload to
```
@Async
```
/Queues. Wrap logic in try/catch; log errors and use
```
@Retryable
```
for retry on transient failures.

Lock Tasks with ShedLock

Problem:
```
@Scheduled
```
runs on ALL pods in K8s.
Solution: Use ShedLock to guarantee single execution.
Config: Set
```
lockAtMostFor
```
(deadlock safety) and
```
lockAtLeastFor
```
(debounce).

See implementation examples for ShedLock distributed task configuration and scheduler pool setup.

Anti-Patterns

No Default Pool: Configure dedicated TaskScheduler (default 1 thread).
No duplicates: Use ShedLock for distributed cron in multi-pod deployments.
No task state: Design tasks to idempotent; assume pod can restart.
