Regd. Validation of Date format for a Path Param

[Thirumalarao Kankanala]

Hi All,

Greetings for the day J

 I wanted to use a regular expression to validate the input date format as “yyyy-mm-dd” which is a path parameter.

I tried as follows, but it is giving the Invalid syntax for the expression '[0-9]{4}-(0[1-9]|1[0-2])-(0[1-9]|[1-2][0-9]|3[0-1]' Exception.

       @GET

       @Path("/{estdDate: [0-9]{4}-(0[1-9]|1[0-2])-(0[1-9]|[1-2][0-9]|3[0-1]}")

       public EstdDateResponse SendDateResponse(

                     @PathParam("estdDate") String estdDate)

                     throws DatatypeConfigurationException {

}

 I don't want to pass format to validate in resource request.

Please let me know how to use regular expressions to validate the date format as defined.

Hi,

you might want to take a look at Dropwizard's DateTimeParam [1, 2]. It
should be reasonably straightforward to create a similar class for
LocalDate [3] (pull requests welcome).
