[Solved] Identify the error in this async method that uses Future and explain why exceptions are not handled properly: @Async public Future loadData() { throw new RuntimeException("Failed"); } | Spring Boot

Spring Boot - Async Processing

Identify the error in this async method that uses Future and explain why exceptions are not handled properly:

@Async
public Future loadData() {
  throw new RuntimeException("Failed");
}

AFuture cannot be used with @Async methods

BMethod should not be annotated with @Async when returning Future

CThrowing exception directly in async method causes it to be lost; should return Future with exception

DRuntimeException must be caught inside the method before throwing

Step-by-Step Solution

Solution:

Step 1: Understand async method exception handling
Exceptions thrown directly in async methods returning Future are not propagated properly.
Step 2: Proper way to handle exceptions in Future
Return a Future that completes exceptionally instead of throwing directly.
Final Answer:
Throwing exception directly in async method causes it to be lost; should return Future with exception -> Option C
Quick Check:
Throwing exceptions directly in async Future methods is incorrect [OK]

Quick Trick: Return Future with exception, don't throw directly in async methods [OK]
