This is sample of basic validation support in spring, to simplify spring boot.

Controller @RequestBody Parameter Validation

Look into com.tiket.tix.poc.validate.controller.PeopleController and its tests in com.tiket.tix.poc.validate.controller.PeopleControllerTests.

Important to note, beside @org.springframework.validation.annotation.Validated annotation, we have to check violation via org.springframework.validation.BindingResult object, which declared next to @RequestBody parameter.

Service Method Parameter Validation

Look into com.tiket.tix.poc.validate.service.RegistrationService and its tests in com.tiket.tix.poc.validate.service.RegistrationServiceTests.

Also look into com.tiket.tix.poc.validate.SampleApplication, to enable method parameter validation, a bean of type org.springframework.validation.beanvalidation.MethodValidationPostProcessor declared there

@SpringBootApplication
public class SampleApplication {
    // ... Omitted ...
    
    @Bean
    MethodValidationPostProcessor methodValidationEnabler() {
        return new MethodValidationPostProcessor();
    }
}
