问题 I have an "AllowedValuesValidator.java" class: public class AllowedValuesValidator implements ConstraintValidator<AllowedValues, String> { String[] values; String defaultValue; @Override public void initialize(AllowedValues constraintAnnotation) { values = constraintAnnotation.allowedValues(); defaultValue = constraintAnnotation.defaultValue(); } @Override public boolean isValid(String value, ConstraintValidatorContext context) { if (!StringUtils.isEmpty(defaultValue) && StringUtils.isEmpty

问题 I'm learning about Hibernate Validation in a Spring Boot app and I have a Rest controller and a POST method. And when I make a request, if a field isn't validated successfully, the client should receive 400 Bad Request and in the body a message like this "validation failed". And I try to do this, but the message didn't come. This is the Body: { "timestamp": "2020-06-06T07:56:11.377+00:00", "status": 400, "error": "Bad Request", "message": "", "path": "/ibantowallet" } And in the console logs

问题 I have a class: class User( var name: String ) And a mapped post request: @PostMapping("/user") fun test(@Valid @RequestBody user: User) { //... } What if a client will send a JSON of a user with name: null ? Will it be rejected by the MVC Validator or an exception will be throwed? Should I annotate name with @NotNull ? Unfortunately, I cannot check that because only can write tests (it is not available to create User(null) ). 回答1: You can avoid using @NotNull , as it'll never get triggered

问题 I do validation with JSR-303 in my Spring app, it works as needed. This is an example: @Column(nullable = false, name = "name") @JsonProperty("customer_name") @NotEmpty @Size(min = 3, max = 32) private String name; And REST API clients use customer_name as name of input field that send to API bud validation field error org.springframework.validation.FieldError returns name as name of the field. Is there some way hot to get JSON-ish name that is specified in @JsonProperty ? Or do I have to

问题 I am using IBM JAX-RS implementation to develop my REST APIs. I am looking to include validation of resource method parameters using Bean Validation (annotations) support provided in JAX-RS 2.0. I know that Jersey implementation supports this feature (https://jersey.java.net/documentation/latest/bean-validation.html). Is there a similar support available with IBM JAX-RS implementation on WAS 8.5.5? If so could you please direct me to some tutorial on how to accomplish this? I am specifically
