    Customize message from Bean Validation with JAX-RS response

    Rudy De Busscher Newbie

      Hi All,

       

      (Using Wildfly)

       

      I have some JAX-RS methods that take JSON objects as parameter.

       

      On These parameters, I have placed some validation constraints, like @Size, with a custom message.  This custom message is used but a lot of more information is available in the response of the REST call which.

       

      The JAXRS controller

       

          @POST

          @Consumes(MediaType.APPLICATION_JSON)

          @Produces(MediaType.APPLICATION_JSON)

          public RegistrationResult newRegistration(@Valid RegistrationDTO registrationDTO) {

              ...

          }

       

      The DTO class

      public class RegistrationDTO {

       

          @NotNull

          @Size(min = 1, max=30, message = "First name (firstName) length must be between 1 and 30 characters long.")

          private String firstName;

       

       

          @NotNull

          @Size(min = 1, max=50, message = "Last name (lastName) length must be between 1 and 50 characters long.")

          private String lastName;

       

      ...

      }

       

      And the response

      [PARAMETER]

      [newRegistration.arg0.lastName]

      [Last name (lastName) length must be between 1 and 50 characters long.]

      []

       

       

      The only way that I have found to answer with a proper JSON object (now it is text), is to write a WriterInterceptor and parse the response from RestEasy. Because I need to return a JSON object as answer (RegistrationResult) where there is some place to put error messages.

       

      Anyone an idea how I can intercept the generation of the current String response?

       

      Thx a lot
