Spring Framework Research & Evidence-Based Practice 3

Question 1

Which Spring Boot Actuator endpoint exposes a structured health check that can be used as evidence of application readiness in CI/CD pipelines?

Accepted Answer

/actuator/health

Answer

The /actuator/health endpoint returns a structured JSON report of application health indicators, commonly used as readiness/liveness probes in CI/CD and Kubernetes.

Question 2

A team wants to validate Spring Security configuration changes don't break existing access rules. What is the recommended evidence-based testing strategy?

Accepted Answer

Use @WithMockUser and MockMvc security tests

Answer

@WithMockUser combined with MockMvc allows automated, repeatable security integration tests that verify access rules without requiring a running server.

Question 3

What Spring framework feature enables reproducible, data-driven tests by pre-populating the database with known state before each test?

Accepted Answer

@Sql annotation

Answer

@Sql allows specifying SQL scripts to execute before or after a test method, ensuring a known and reproducible database state for evidence-based testing.

Question 4

When researching Spring bean initialization order issues, which tool provided by Spring Framework helps visualize the dependency graph?

Accepted Answer

ApplicationContext.getBeanDefinitionNames() combined with dependency introspection

Answer

Programmatic inspection via getBeanDefinitionNames() and BeanFactory dependency APIs, or IDE plugins, are the evidence-based approaches for diagnosing Spring bean dependency ordering issues.

Question 5

Which JMH (Java Microbenchmark Harness) integration practice is recommended when benchmarking Spring-managed beans to get accurate results?

Accepted Answer

Initialize the Spring context in @Setup and inject beans before timing

Answer

The recommended practice is to initialize the Spring context once in a @Setup method and inject beans before the timed benchmark loop, isolating context startup from the measured operation.
