Java Spring Tricks & Best Practices 1. Use @RestController Instead of @Controller + @ResponseBody @RestController public class MyController { @GetMapping("/hello") public String hello() { return "Hello, World!"; } } 2. Enable Caching with @Cacheable @Cacheable("users") public User getUserById(Long id) { return userRepo.findById(id).get(); } 3. Use @Transactional for Automatic Rollback @Transactional public void transferMoney(Account from, Account to, double amount) { /* logic */ } 4. Profile-Based Configurations (@Profile) @Profile("dev") @Service public class DevService { /* Development-specific code */ } 5. Use @Async for Background Tasks @Async public void sendEmail(String to) { /* Async email sending logic */ } 6. Externalize Configs with @Value @Value("${app.name}") private String appName; 7. Use Lombok to Reduce Boilerplate Code @Getter @Setter @AllArgsConstructor public class User { private String name; priv ate int age; } Want advanced Spring tricks? read less
