I'm using resteasy-servlet-spring-boot-starter 6.2.0.Final with springboot 3.2.2. I'm not sure how can we serve static files from /META-INF/resources/api. https://docs.jboss.org/resteasy/docs/6.2.9.Final/userguide/ suggests that we can use filter org.jboss.resteasy.plugins.server.servlet.FilterDispatcher but it doesn't seem to help as the servlet HttpServlet30Dispatcher just sends not-found response back. Looking for pointers to resolve this.

@srpsingh I'll find time to check your question and give back my answer by the end of next week.

@srpsingh Here is a simple solution: https://stackoverflow.com/a/51074375/1212922

Does it solve your problem?

I haven't checked whether this solution works or not:

• https://www.baeldung.com/spring-mvc-static-resources

If I have time I'll verify the above solution works or not.

I have verified the above solution works:

• Add static files liweinan/Resteasy2168SpringBoot#5

I assume this question is answered. If there is any more problem please reopen the discussion.

@liweinan Thanks. I was able to use your information and find a solution. I was much fixated on Filter way of resolving it. I've put the following code (need a lot of improvements though) that seem to be working:

@component
@path("")
public class StaticResourcesResource
{

@Inject
ServletContext context;

@GET
//    @Path("{path: ^api\\/.*}")
@Path("{path: ^api.*}")
public Response staticResources(@PathParam("path") final String path)
{

    // FIXME there must be better way to make this response
    String processedPath = null;
    if (path.equals("api") || path.equals("api/"))
    {
        processedPath = "api/index.html";
    }
    else
    {
        processedPath = path;
    }

    InputStream resource = context.getResourceAsStream(String.format("%s", processedPath));

    String contentType = null;
    if (processedPath.endsWith(".html"))
    {
        contentType = "text/html";
    } else if (processedPath.endsWith(".js"))
    {
        contentType = "application/javascript";
    }
    else if (processedPath.endsWith(".css"))
    {
        contentType = "text/css";
    }
    else if (processedPath.endsWith(".png"))
    {
        contentType = "image/png";
    }

    return Objects.isNull(resource)
            ? Response.status(NOT_FOUND).build()
            : Response.ok().entity(resource).type(contentType).build();
}

}
