Using @RequestParam annotated method with swagger ui

Question

I am using Springfox libraries to generate documentation for REST service and display it in Swagger UI. I followed the directions in Springfox documentation.

I have one controller, which uses parameters from query string and the method is mapped as following:

@ApiOperation(value = "")
@RequestMapping(method = GET, value = "/customcollection/{id}/data")
public Iterable<CustomeType> getData(@ApiParam(value = "The identifier of the time series.") 
    @PathVariable String id,
    @ApiParam(name = "startDate", value = "start date", defaultValue = "")
    @RequestParam("startDate") String startDate,
    @ApiParam(name = "endDate", value = "end date", defaultValue = "")
    @RequestParam("endDate") String endDate)

The resulting mapper in swagger-ui then displayed as:

GET /customcollection/{id}/data{?startDate,endDate}

Parameters are displayed correctly in the UI:

But when I click on Try it Out, the request URL is misformed:

http://localhost:8080/customcollection/1/data{?startDate,endDate}?startDate=1&endDate=2

How can it be fixed?

Answer 1

This was caused by the line

 enableUrlTemplating(true)

in Docket configuration which I copied from example and forgot to remove.

After removing this line everything is working as expected.
