Spring Boot - Async Processing

Consider a Spring Boot app with multiple async executors defined. How can you specify which executor an @Async method should use?

ASet the executor name in application.properties.

BUse @Async("executorBeanName") with the bean name of the desired executor.

CUse @EnableAsync with an executorName parameter.

DName the method with the executor name prefix.

Step-by-Step Solution

Solution:

Step 1: Understand executor selection
@Async accepts a value specifying the executor bean name to use for that method.
Step 2: Check other options
application.properties and @EnableAsync do not specify executor per method; method naming has no effect.
Final Answer:
Use @Async("executorBeanName") with the bean name of the desired executor. -> Option B
Quick Check:
Specify executor by bean name in @Async [OK]

Quick Trick: Pass executor bean name as @Async value to select executor [OK]
