I got a working spring boot rest service. When the path is wrong it doesn't return anything. No response At all. At the same time it doesn't throw error either. Ideally I expected a 404 not found error.
I got a GlobalErrorHandler
@ControllerAdvice
public class GlobalErrorHandler extends ResponseEntityExceptionHandler {
}
There is this method in ResponseEntityExceptionHandler
protected ResponseEntity<Object> handleNoHandlerFoundException(NoHandlerFoundException ex, HttpHeaders headers,
HttpStatus status, WebRequest request) {
return handleExceptionInternal(ex, null, headers, status, request);
}
I have marked error.whitelabel.enabled=false in my properties
What else must I do for this service to throw a 404 not found response back to clients
I referred a lot of threads and don't see this trouble faced by anybody.
This is my main application class
@EnableAutoConfiguration // Sprint Boot Auto Configuration
@ComponentScan(basePackages = "com.xxxx")
@EnableJpaRepositories("com.xxxxxxxx") // To segregate MongoDB
// and JPA repositories.
// Otherwise not needed.
@EnableSwagger // auto generation of API docs
@SpringBootApplication
@EnableAspectJAutoProxy
@EnableConfigurationProperties
public class Application extends SpringBootServletInitializer {
private static Class<Application> appClass = Application.class;
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(appClass).properties(getProperties());
}
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
