RESTEasy using Application/BeanConfig not seeing resources

[hancholo]

Can't figure this seemingly easy problem out

Using Wildfly 10, have a basic REST CRUD webapp with a /hello endpoint for testing, which works fine.

Set up Swagger per Swagger Core RESTEasy 2.X Project Setup 1.5

and got to the point of the 'empty' swagger.json :

{
swagger: "2.0",
info: {},
version: "0.0.3",
title: "HelloWorld2Api"
host: "http://localhost:8080",
basePath: "/HelloWorld2/rest",
schemes: [] "http"
}

my setup:

in pom.xml:

<dependency>
   <groupId>io.swagger</groupId>
   <artifactId>swagger-jaxrs</artifactId>
    <version>1.5.0</version>
</dependency>

in jboss-web.xml

<context-root>HelloWorld2</context-root>

Here are the annotations on my test resource:

@Path("hello")
@Api(value="hello")
@Produces({"application/json", "application/xml"})
public class HelloREST { ... }

Here's the extended Application:

@ApplicationPath("rest")
public class ApplicationConfig extends Application {


    /**
     * Custom constructor for Swagger
     */
    public ApplicationConfig() {
        BeanConfig beanConfig = new BeanConfig();
        beanConfig.setTitle("HelloWorld2Api");
        beanConfig.setVersion("0.0.3");
        beanConfig.setSchemes(new String[]{"http"});
        beanConfig.setHost("http://localhost:8080");
        beanConfig.setBasePath("/HelloWorld2/rest");
        beanConfig.setScan(true);    
        beanConfig.setResourcePackage("io.swagger.resources");
      //  beanConfig.setResourcePackage("helloworld2.rest");
        beanConfig.setPrettyPrint(true);
    }


    @Override
    public Set<Class<?>> getClasses() {
        Set<Class<?>> resources = new java.util.HashSet<>();
       
        resources.add(helloworld2.rest.HelloREST.class);
       
        resources.add(io.swagger.jaxrs.listing.ApiListingResource.class);
        resources.add(io.swagger.jaxrs.listing.SwaggerSerializers.class);
       
        return resources;
    }


}

If the above commented out line:    

  //  beanConfig.setResourcePackage("helloworld2.rest")

is used instead of

  beanConfig.setResourcePackage("io.swagger.resources");

then the swagger.json returns

Context Path:
/HelloWorld2

Servlet Path:
/rest

Path Info:
/swagger.json

Query String:
null
Stack Trace
org.jboss.resteasy.spi.UnhandledException: java.lang.ArrayIndexOutOfBoundsException: 1

I've tried all sorts of permutations of configurations, paths, using xml descriptors and not, but can't find the problem. I would very much prefer to use the non-Spring beanConfig technique.  Where's my mistake?

Hi,

 

First thing would be to use the latest version which is 1.5.9.

Second, the output of the swagger.json you share doesn’t make sense as it’s  not even JSON.

Is that the full output you get? Anything else in the logs?

Good to know.  Someone should update the docs since I can't be the first person to cut and paste the maven dependency.

And that did it!!!!

Thanks so much.

Maintenance wise, it’d be very difficult to keep the docs updated with the latest version all the time.

However, the docs do say –

"Check the change log to see information about the latest version and the changes from previous versions.”
