带有Swagger UI的Wildfly Swarm会产生空白页面

Question

我使用WildFly Swarm Project Generator创建了一个小型的WildFly-Swarm休息应用程序。当我构建并运行我的应用程序，如果去 http://localhost:8080/swagger我按预期得到了我的Swagger.json：

{
   "swagger":"2.0",
   "info":{

   },
   "tags":[
      {
         "name":"hello"
      }
   ],
   "paths":{
      "/hello":{
         "get":{
            "tags":[
               "hello"
            ],
            "summary":"Just say hello...",
            "description":"Something",
            "operationId":"doGet",
            "produces":[
               "text/plain"
            ],
            "parameters":[

            ],
            "responses":{
               "200":{
                  "description":"successful operation",
                  "schema":{
                     "type":"string"
                  }
               }
            }
         }
      }
   }
}

但是当我去http://localhost:8080/swagger-ui时，我得到一个空页。我是否缺少一些配置，或者它应该开箱即用，没有额外的配置？

下面我附上了我的源码和pom.xml：

我的来源：

import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;

import javax.ws.rs.Path;
import javax.ws.rs.core.Response;
import javax.ws.rs.GET;
import javax.ws.rs.Produces;

@Path("/hello")
@Api(value = "/hello", description = "Sey hello...")
public class HelloWorldEndpoint {

    @GET
    @Produces("text/plain")
    @ApiOperation(
            value = "Just say hello...",
            notes = "Something",
            response = String.class
    )
    public Response doGet() {
        return Response.ok("Hello from WildFly Swarm!").build();
    }
}

我的pom.xml看起来像这样：
