Global Exception Handling with @ControllerAdvice

Centralize exception handling across all controllers with @ExceptionHandler and @ControllerAdvice.

The Problem Without Global Handling

Without global exception handling, every controller method needs try-catch blocks, error response building is duplicated, and exception details leak to clients.

@ControllerAdvice and @RestControllerAdvice

@ControllerAdvice defines a global exception handler class. @RestControllerAdvice adds @ResponseBody so all handler methods return JSON automatically.

@RestControllerAdvice
public class GlobalExceptionHandler {
    // @ExceptionHandler methods go here
}
