A developer is writing an integration test for a service layer that interacts with a database. To ensure the test is isolated, they want to use an in-memory H2 database only for the test run. The main application uses PostgreSQL. What is the most idiomatic Spring Boot approach to achieve this?

A developer needs to inject a list of all beans that implement the PaymentGateway interface into a service. Which of the following injection points correctly accomplishes this?

A Spring Boot application is being deployed to a new environment where the HTTP port must be configured via an environment variable named APP_PORT. Which entry in application.properties allows the application to use this environment variable, while defaulting to port 8080 if it's not set?

Scenario
A logistics company is developing a ShipmentTrackingService. This service consumes messages from an external system via an API, processes them, and updates the shipment status in a database. The processing logic is complex and can occasionally fail due to transient network issues or invalid data. The architects have decided to use Spring's AOP to implement a retry mechanism for the core processing method.

Code

@Service
public class ShipmentProcessor {
@Transactional
@Retryable(value = DataAccessException.class, maxAttempts = 3, backoff = @Backoff(delay = 1000))
public void processShipment(ShipmentData data) {
// ... database update logic ...
if (isInvalid(data)) {
throw new InvalidShipmentDataException("Invalid data");
}
}
}

Requirements

1. The method should retry up to 3 times if a DataAccessException occurs.
2. If an InvalidShipmentDataException (which is a RuntimeException but not a DataAccessException) is thrown, the method should NOT retry, and the transaction should be rolled back immediately.
3. The retry and transactional behaviors must work together correctly.

Question
Given the code and requirements, what is the expected behavior when processShipment is called with data that causes an InvalidShipmentDataException?

A service method in ServiceA calls a public method in ServiceB. Both methods are annotated with @Transactional(propagation = Propagation.REQUIRES_NEW). What is the transactional behavior when the method in ServiceA is invoked?

A development team is building a library of custom Spring Boot auto-configurations. To ensure a custom configuration MyCustomAutoConfiguration is only activated when the ThirdPartyService.class is present on the classpath, and a bean of type DataSource has already been configured by another auto-configuration, which combination of annotations should be used on the configuration class?

A developer is implementing an AOP aspect to log method executions. They notice that when a public method calls another public method within the same service bean, the advice is not triggered for the second, inner method call. What is the fundamental reason for this behavior in Spring's proxy-based AOP?

A financial application needs to perform a complex operation involving two separate database updates. The outer service method, transferFunds(), is annotated with @Transactional(propagation = Propagation.REQUIRED). It calls an inner service method, logAudit(), which must commit its record regardless of whether the transferFunds operation succeeds or fails. Which propagation level should be applied to the logAudit() method to achieve this behavior?

A developer needs to configure a Spring Security setup for a REST API. The requirement is to allow unauthenticated access to /api/public/** endpoints, while all other endpoints under /api/** must be authenticated. Which two of the following HttpSecurity configurations correctly implement this requirement? (Select TWO)

When writing a slice test for a Spring Data JPA repository using @DataJpaTest, the test transaction will, by default, roll back at the end of each test method.
