I’m encountering an issue with my Spring Boot application and need assistance to resolve it. Below is the relevant code and the error message:
MessageRepository:
package com.varpm.listener;
import com.test.model.MessageEntity;
import org.springframework.data.repository.CrudRepository;
import org.springframework.stereotype.Repository;
@Repository
public interface MessageRepository extends CrudRepository<MessageEntity, String> {
}
MessageHandlingService:
package com.test.listener;
import com.test.model.MessageEntity;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
@Service
public class MessageHandlingService {
@Autowired
private MessageRepository messageRepository;
public void handleRetransmissionFailure(String messageId, String message) {
// Retrieve the message entity by ID or create a new one
MessageEntity entity = messageRepository.findById(messageId).orElseGet(() -> {
MessageEntity newEntity = new MessageEntity();
newEntity.setId(messageId);
return newEntity;
});
// Update message details and retry count
entity.setMessage(message);
entity.setAcknowledged(false);
entity.setRetryCount(entity.getRetryCount() + 1);
entity.setTimestamp(System.currentTimeMillis());
// Save the message entity in Redis
messageRepository.save(entity);
// Log the transmission failure
logTransmissionFailure(messageId);
// You may also have additional logic here, such as notifying administrators or implementing custom retry policies.
}
private void logTransmissionFailure(String messageId) {
System.out.println("Transmission failure ");
}
}
**MyApplication:**
package com.test.main;
@SpringBootApplication
@ComponentScan(basePackages = {"com.test","com.test.model"})
public class MyApplication {
public static void main(String[] args) throws IOException {
SpringApplication.run(MyApplication.class, args);
}
}
I’m receiving the following error when trying to run the application:
APPLICATION FAILED TO START
Description:
Field messageRepository in com.varpm.listener.MessageHandlingService required a bean of type ‘com.varpm.listener.MessageRepository’ that could not be found.
The injection point has the following annotations:
– @org.springframework.beans.factory.annotation.Autowired(required=true)
Action:
Consider defining a bean of type ‘com.varpm.listener.MessageRepository’ in your configuration.
Process finished with exit code 1
Your assistance would be greatly appreciated.
Thank you in advance for your help.

Does your MessageEntity class have @Entity annotation?
Spring can’t find a bean of type
com.varpm.listener.MessageRepository
because the packagecom.varpm.listener
isn’t declared in the@ComponentScan
configuration
