RESTEasy on Undertow. swagger.json is not found

[amreladawy]

Hi Ron,

I am trying to get swagger.json on a project that is using REASTEasy on Undertow.

Here is my AppApi class

@ApplicationPath("/v1")
public class ApiApp extends Application {

    @Override
    public Set<Class<?>> getClasses() {
    HashSet<Class<?>> classes = new HashSet<Class<?>>();
    classes.add(Users.class);
    classes.add(Orders.class);
    classes.add(Admin.class);
    classes.add(Menus.class);
    classes.add(SecurityFilter.class);
    return classes;
    }

    public ApiApp() {
    BeanConfig beanConfig = new BeanConfig();
    beanConfig.setTitle("QMenu API");
    beanConfig.setVersion("1.0.0");
    beanConfig.setSchemes(new String[] { "http" });
    beanConfig.setHost("localhost:8090");
    beanConfig.setBasePath("/");
    beanConfig.setResourcePackage("com.eigonic.qmenu.core.api.rest");
    beanConfig.setPrettyPrint(true);
    beanConfig.setScan(true);
    }

}

I went debuggingthrough the method beanConfig.setScan(true); and I found that swagger is able to read my resources classes successfully.

when I get the URL http://localhost:8090/v1/swagger.json I get 404

with the following error

9:20:35.763 [XNIO-1 task-2] ERROR (ExceptionHandler.java:199) - RESTEASY002010: Failed to execute} javax.ws.rs.NotFoundException: RESTEASY003210: Could not find resource for full path: http://localhost:8090/v1/swagger.json at org.jboss.resteasy.core.registry.ClassNode.match(ClassNode.java:75) ~[resteasy-jaxrs-3.0.14.Final.jar:3.0.14.Final] at org.jboss.resteasy.core.registry.RootClassNode.match(RootClassNode.java:48) ~[resteasy-jaxrs-3.0.14.Final.jar:3.0.14.Final] at org.jboss.resteasy.core.ResourceMethodRegistry.getResourceInvoker(ResourceMethodRegistry.java:445) ~[resteasy-jaxrs-3.0.14.Final.jar:3.0.14.Final] at org.jboss.resteasy.core.SynchronousDispatcher.getInvoker(SynchronousDispatcher.java:257) [resteasy-jaxrs-3.0.14.Final.jar:3.0.14.Final] at org.jboss.resteasy.core.SynchronousDispatcher.invoke(SynchronousDispatcher.java:194) [resteasy-jaxrs-3.0.14.Final.jar:3.0.14.Final] at org.jboss.resteasy.plugins.server.servlet.ServletContainerDispatcher.service(ServletContainerDispatcher.java:221) [resteasy-jaxrs-3.0.14.Final.jar:3.0.14.Final] at org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher.service(HttpServletDispatcher.java:56) [resteasy-jaxrs-3.0.14.Final.jar:3.0.14.Final] at org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher.service(HttpServletDispatcher.java:51) [resteasy-jaxrs-3.0.14.Final.jar:3.0.14.Final] at javax.servlet.http.HttpServlet.service(HttpServlet.java:790) [jboss-servlet-api_3.1_spec-1.0.0.Final.jar:1.0.0.Final] at io.undertow.servlet.handlers.ServletHandler.handleRequest(ServletHandler.java:85) [undertow-servlet-1.3.10.Final.jar:1.3.10.Final] at io.undertow.servlet.handlers.security.ServletSecurityRoleHandler.handleRequest(ServletSecurityRoleHandler.java:62) [undertow-servlet-1.3.10.Final.jar:1.3.10.Final] at io.undertow.servlet.handlers.ServletDispatchingHandler.handleRequest(ServletDispatchingHandler.java:36) [undertow-servlet-1.3.10.Final.jar:1.3.10.Final] at io.undertow.servlet.handlers.security.SSLInformationAssociationHandler.handleRequest(SSLInformationAssociationHandler.java:131) [undertow-servlet-1.3.10.Final.jar:1.3.10.Final] at io.undertow.servlet.handlers.security.ServletAuthenticationCallHandler.handleRequest(ServletAuthenticationCallHandler.java:57) [undertow-servlet-1.3.10.Final.jar:1.3.10.Final] at io.undertow.server.handlers.PredicateHandler.handleRequest(PredicateHandler.java:43) [undertow-core-1.3.10.Final.jar:1.3.10.Final] at io.undertow.security.handlers.AbstractConfidentialityHandler.handleRequest(AbstractConfidentialityHandler.java:46) [undertow-core-1.3.10.Final.jar:1.3.10.Final] at io.undertow.servlet.handlers.security.ServletConfidentialityConstraintHandler.handleRequest(ServletConfidentialityConstraintHandler.java:64) [undertow-servlet-1.3.10.Final.jar:1.3.10.Final] at io.undertow.security.handlers.AuthenticationMechanismsHandler.handleRequest(AuthenticationMechanismsHandler.java:60) [undertow-core-1.3.10.Final.jar:1.3.10.Final] at io.undertow.servlet.handlers.security.CachedAuthenticatedSessionHandler.handleRequest(CachedAuthenticatedSessionHandler.java:77) [undertow-servlet-1.3.10.Final.jar:1.3.10.Final] at io.undertow.security.handlers.AbstractSecurityContextAssociationHandler.handleRequest(AbstractSecurityContextAssociationHandler.java:43) [undertow-core-1.3.10.Final.jar:1.3.10.Final] at io.undertow.server.handlers.PredicateHandler.handleRequest(PredicateHandler.java:43) [undertow-core-1.3.10.Final.jar:1.3.10.Final] at io.undertow.server.handlers.PredicateHandler.handleRequest(PredicateHandler.java:43) [undertow-core-1.3.10.Final.jar:1.3.10.Final] at io.undertow.servlet.handlers.ServletInitialHandler.handleFirstRequest(ServletInitialHandler.java:284) [undertow-servlet-1.3.10.Final.jar:1.3.10.Final] at io.undertow.servlet.handlers.ServletInitialHandler.dispatchRequest(ServletInitialHandler.java:263) [undertow-servlet-1.3.10.Final.jar:1.3.10.Final] at io.undertow.servlet.handlers.ServletInitialHandler.access$000(ServletInitialHandler.java:81) [undertow-servlet-1.3.10.Final.jar:1.3.10.Final] at io.undertow.servlet.handlers.ServletInitialHandler$1.handleRequest(ServletInitialHandler.java:174) [undertow-servlet-1.3.10.Final.jar:1.3.10.Final] at io.undertow.server.Connectors.executeRootHandler(Connectors.java:202) [undertow-core-1.3.10.Final.jar:1.3.10.Final] at io.undertow.server.HttpServerExchange$1.run(HttpServerExchange.java:793) [undertow-core-1.3.10.Final.jar:1.3.10.Final] at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) [?:1.8.0_65] at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) [?:1.8.0_65] at java.lang.Thread.run(Thread.java:745) [?:1.8.0_65]

Looks like you're missing this step - https://github.com/swagger-api/swagger-core/wiki/Swagger-Core-RESTEasy-2.X-Project-Setup-1.5#using-a-custom-application-subclass.

I ecountered the same problem

[webron]

Then you're missing a step still. Start from the beginning, follow the instructions. It's pretty straightforward.

Hello I encountered the same problem.
I tried to configure it both by custom Application class and Servlet. Also with specified resources paths and with RESTEasy auto-scanning and still getting 404 (javax.ws.rs.NotFoundException) when trying to access swagger.json file.

Do you have any idea what is the problem here?
Thanks

Hello, I followed the same pattern, I am getting swagger.json but with only GET request.. There are so many PUT, POST and DELETE requests which are not shown in swagger.json file.

Any idea how to solve it?

Thanks in advance!
