SpringBoot Bean validation @NotEmpy is not Working

Question

I been trying to use spring @NotEmpty to make some input paramters in a REST api mandatory.

So far this is what I've achieved.

RestController

@RestController
public class ResourceController {

    @Autowired
    private GestionaDatosCrmService service;

    @PostMapping(path = Constantes.OBTENER_DATOS_CRM)
    @ResponseStatus(HttpStatus.CREATED)
    public ObtenerDatosCrmResponse obtenerDatosCrm(@RequestHeader HttpHeaders headerRequest,
            @Valid @RequestBody ObtenerDatosCrmRequest request, HttpServletResponse headerResponse) {
        return service.obtenerDatosCrm(headerRequest, request, headerResponse);
    }
}

Request Object

import javax.validation.constraints.NotEmpty;

//import org.hibernate.validator.constraints.NotEmpty;

public class ObtenerDatosCrmRequest {

    @NotEmpty(message = "Please provide a number")
    private String numSN;
    private String callID;

    public String getNumSN() {
        return numSN;
    }

    public void setNumSN(String numSN) {
        this.numSN = numSN;
    }

    public String getCallID() {
        return callID;
    }

    public void setCallID(String callID) {
        this.callID = callID;
    }
}

Note this important detail I'm using javax.validation.constraints.NotEmpty for the @NotEmpty annotation but that doesn't work when I change to org.hibernate.validator.constraints.NotEmpty that is Deprecated the @NotEmpty kicks in and I get a 400 Bad request error when testing.

Im using spring boot 2.2.2.RELEASE, is there some know bug or issue about this?

Answer 1

I've had exactly the same issue and the solution that worked for me was to explicitly require a newer hibernate-validator version.

Gradle:

implementation 'org.hibernate.validator:hibernate-validator:6.1.2.Final'

Maven:

<dependency>
  <groupId>org.hibernate.validator</groupId>
  <artifactId>hibernate-validator</artifactId>
  <version>6.1.2.Final</version>
</dependency>
