Spring Boot - Messaging

Given the code snippet:

rabbitTemplate.convertAndSend("myExchange", "myKey", "Hello")

What happens if the exchange "myExchange" does not exist?

AThe message is sent to the default exchange instead

BThe message is silently dropped without error

CThe exchange is automatically created and message sent

Step-by-Step Solution

Solution:

Step 1: Understand RabbitMQ behavior on missing exchange
If a message is sent to a non-existent exchange, RabbitMQ throws a channel-level exception.
Step 2: Check Spring Boot RabbitTemplate behavior
Spring's RabbitTemplate propagates this exception at runtime, so the application will get an error.
Final Answer:
An exception is thrown at runtime indicating the exchange is missing -> Option D
Quick Check:
Missing exchange causes runtime exception [OK]

Quick Trick: Missing exchange causes runtime error, not silent failure [OK]
