Re: Can't Generate swagger.json With CXFNonSpringJaxrsServlet

[Ron Ratovsky]

Hi Jeff,

 

Since you’re using the Swagger2Feature, you could get better support for it in 
the CXF mailing list as that’s their implementation for it.

Subject: Can't Generate swagger.json With CXFNonSpringJaxrsServlet

 

I am attempting to integrate swagger with a legacy REST service implemented 
using an older version of CXF.  I've attempted several configurations but can't 
get the swagger.json to generate.  Guidance on getting this resolved is greatly 
appreciated.  Please see project code below: 

 

HelloService.java

 

package swaggerRest;

import javax.ws.rs.*;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;

@Path("/sample")
@Api(value = "/sample", description = "Sample REST for Swagger Testing")
public class HelloService {
 @GET
 @Path("hello")
 @ApiOperation(value = "Get hello message", response = String.class)
 public String sayHello(){
 return "Hello World";
 }
}
