You need a focused list of Spring Framework interview questions to prioritize study and avoid last‑minute panic.
If you're preparing for a Java backend role, these Spring Framework interview questions target the core concepts, coding challenges, architecture choices, and behavioral examples recruiters ask most. Drawing on high‑traffic guides and question banks, this article organizes 30 real interview‑ready questions with concise model answers, examples, and quick preparation tips so you can practice with purpose and confidence. Takeaway: use these Spring Framework interview questions to guide timed drills and mock interviews.
Why these Spring Framework interview questions matter
Answer: Hiring teams ask focused Spring Framework interview questions because they reveal practical design, debugging, and production readiness.
Spring skills map directly to day‑one contributions in backend teams: dependency injection, MVC routing, REST controllers, security, and performance tuning. Industry lists and interview collections show recurring themes that predict hiring success—covering fundamentals, Spring Boot comparisons, AOP, security, and testing (Edureka, InterviewBit). Preparing these Spring Framework interview questions reduces scope ambiguity and helps you shape hands‑on examples. Takeaway: mastering these core Spring Framework interview questions shortens the path from screening to offer.
How to use these Spring Framework interview questions to structure prep
Answer: Use these Spring Framework interview questions to build three practice modes: concepts review, coding drills, and mock behavioral answers.
Start with short concept flashcards for DI, IoC, and MVC, then schedule 30–60 minute coding sessions for controllers, services, and tests. Add behavioral rehearsals for project stories that show impact. Combine official Q&A sources and timed coding platforms to simulate interviews (CoderPad, Indeed). Takeaway: rotate study modes using these Spring Framework interview questions for durable recall and interview stamina.
Top 30 Spring Framework interview questions and model answers
Answer: Below are 30 common Spring Framework interview questions with concise, interview‑ready answers and quick follow‑ups to practice.
The list groups questions by theme—fundamentals, coding/deep dives, Spring Boot differences, security & testing, architecture and behavioral examples—so you can focus your next mock interview.
Technical Fundamentals
Q: What is the Spring Framework?
A: An open‑source Java framework for building flexible, loosely coupled enterprise applications with DI, AOP, and modular containers.
Q: What is Inversion of Control (IoC) and Dependency Injection (DI) in Spring?
A: IoC delegates object creation to a container; DI injects dependencies into beans via constructor, setter, or field injection.
Q: What are Spring beans and the Spring IoC container?
A: Beans are managed objects; the IoC container instantiates, configures, and wires beans per configuration metadata.
Q: What are the main types of bean scopes in Spring?
A: Singleton, prototype, request, session, application; singleton is default and single instance per container.
Q: How does autowiring work and what modes exist?
A: Autowiring injects dependencies automatically using byName, byType, constructor, and @Autowired (with optional, required settings).
Spring MVC & REST
Q: How does Spring MVC handle a request?
A: DispatcherServlet routes requests to controllers, which return views or data; HandlerMapping and ViewResolver manage mapping and rendering.
Q: How do you write a REST controller in Spring?
A: Annotate with @RestController and map endpoints with @GetMapping/@PostMapping; return domain objects or ResponseEntity for status control.
Q: How do you handle exceptions in Spring MVC?
A: Use @ExceptionHandler or @ControllerAdvice to centralize error responses and map exceptions to HTTP statuses.
Q: What is model binding and validation in Spring MVC?
A: Spring binds request params to objects and supports validation via JSR‑303 annotations and @Valid with BindingResult checks.
Q: How do you implement content negotiation in Spring?
A: Configure message converters and use Accept headers, @RequestMapping produces/consumes, or ContentNegotiationConfigurer.
Coding & Deep Dives
Q: How do you configure a bean using annotations and Java config?
A: Use @Configuration with @Bean methods or component scanning with @Component/@Service and @ComponentScan.
Q: What is thread safety in Spring beans and how can it be achieved?
A: Make beans stateless, use prototype scope for stateful beans, synchronize access, or use thread‑safe data structures.
Q: What is Spring AOP and where is it used?
A: AOP provides cross‑cutting concerns (logging, transactions) using proxies, pointcuts, and advice types like @Around and @After.
Q: How does transaction management work in Spring?
A: Use @Transactional on methods; Spring manages transactions through PlatformTransactionManager and propagation settings.
Q: How do you test Spring components?
A: Use @SpringBootTest for integration, @WebMvcTest for controllers, and Mockito for unit tests with TestRestTemplate or MockMvc for endpoints.
Spring Boot and Ecosystem
Q: What is the difference between Spring and Spring Boot?
A: Spring Boot auto‑configures, embeds servers, and simplifies dependency management and application bootstrap compared to plain Spring.
Q: What is auto‑configuration in Spring Boot?
A: Conditional @Configuration classes that configure beans when certain classes or properties are present, reducing boilerplate.
Q: When would you prefer Spring over Spring Boot?
A: When full control of configuration is required for legacy systems or when avoiding opinionated auto‑configuration is necessary.
Q: What is @SpringBootApplication and what does it include?
A: A meta‑annotation combining @Configuration, @EnableAutoConfiguration, and @ComponentScan to bootstrap a Spring Boot app.
Q: How do you externalize configuration in Spring Boot?
A: Use application.properties/yml, environment variables, Spring Cloud Config, or @ConfigurationProperties for typed settings.
Security, Performance & Best Practices
Q: What is Spring Security and how do you secure REST APIs?
A: A framework for authentication/authorization; secure APIs with filter chains, JWT/OAuth2, method security, and CSRF controls.
Q: How do you implement caching in Spring?
A: Use @EnableCaching and @Cacheable/@CacheEvict with a provider like Redis or Ehcache for performance improvement.
Q: What are common Spring anti‑patterns to avoid?
A: Heavy controllers, tight coupling to framework classes, excessive use of static state, and inappropriate singleton state.
Q: How do you profile and optimize Spring application performance?
A: Use metrics (Micrometer), JVM profiling, connection pool tuning, lazy initialization, and caching to reduce latency.
Q: How do you secure sensitive configuration values?
A: Use encrypted secrets (Vault), environment variables, and avoid committing credentials; use Spring Cloud Config with encryption.
Architecture, Projects & Behavioral
Q: What Spring projects should you highlight on your resume?
A: Spring Boot microservices, Spring MVC web apps, Spring Data JPA integrations, Spring Security implementations, and automated tests.
Q: How do you explain a design decision using Spring in an interview?
A: Describe the problem, tradeoffs, chosen Spring features, metrics or outcomes, and follow‑up improvements.
Q: Give an example of a time you debugged a Spring production issue.
A: Summarize the root cause (e.g., bean lifecycle, thread leak), steps taken, fixes applied, and monitoring added to prevent recurrence.
Q: How do you approach migrating a monolith to Spring Boot microservices?
A: Incrementally extract bounded contexts, create well‑defined APIs, apply distributed tracing, and use CI/CD to validate each cutover.
Q: Why should we hire you for this Spring role?
A: Focus on relevant Spring experience, measurable outcomes (latency reduction, feature delivery), and how your skills solve their current needs.
Takeaway: practice delivering short, precise answers to these Spring Framework interview questions and back each with a concrete example.
