How to manage string with blanks, comma etc. as PathParam?

Question

I created a web services that needs to get a string with blanks, commas, parenthesis and other special characters. I would like pass it as PathParam but I wasn't able to manage this string.

The string that I want to manage is similar to the follow:

POLYGON((9.5 44.6, 12.5 44.6, 12.5 42.0, 9.5 42.0, 9.5 44.6))

My method is:

@POST
@Path("/j_update_spi/{step}/{srid}/{polygon:.+}")
public Response updateSPI(@PathParam("step") String step,
                          @PathParam("srid") String srid,
                          @PathParam("polygon") String polygon){
...
}

i tried to set ".+" for polygon parameter but it doesn't work (i also tried to use .*).

If I call this service the method doesn't start.

So, are you saying as part of `polygon` you are supposed to pass `9.5 44.6, 12.5 44.6, 12.5 42.0, 9.5 42.0, 9.5 44.6` ? — Ravi, Dec 14 '17 at 05:10
@Ravi : yes, actually I created a method that get only the coordinates as simple box. But I need to get any polygons — N3tMaster, Dec 22 '17 at 11:22
@user1803551 : yes POLYGON is part of the string. This is the standard format WKT (WellKnownText) OGC compliant — N3tMaster, Dec 22 '17 at 11:23
The regex works, your problem is somewhere else. Post the request path. — user1803551, Dec 22 '17 at 15:45
Also post the class declaration and JAX-RS `Application` paths if relevant. — user1803551, Dec 22 '17 at 15:55

I solved my problem: I changed the PathParam "polygon" and made it as optional. Then I changed regex rules into polygon PathParam.

@POST
@Path("/update_spi/{step}/{srid}{polygon:(/polygon/.+?)?}")
public Response updateSPI(@PathParam("step") String step,
                          @PathParam("srid") String srid,
                          @PathParam("polygon") String polygon)

in order to extract the string that defines my WKT Polygon I used split method:

if(!polygon.matches(""))
     polygon = polygon.split("/")[2];
