model-view-controller - 无法将 JAX-RS 服务连接到 MVC 模板

Question

我正在尝试使用 JAX-RS' (Jersey) MVC 模式。尝试联系 http://localhost:8080/myproject/foos/test导致错误，内容如下:

java.io.IOException: The template name, /view, could not be resolved to a fully qualified template name

http://localhost:8080/myproject/foos导致同样的错误。

我错过了什么？

资源:

package resources;

import com.sun.jersey.api.view.Viewable;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;

@Path("foos")
public class FooResource {

    @GET
    @Produces(MediaType.TEXT_HTML)
    public Viewable get() {

        return new Viewable("/index", this);

    }   

    @GET
    @Path("{id}")
    @Produces(MediaType.TEXT_HTML)
    public Viewable get(@PathParam("id") String id) {

        return new Viewable("/view", id);

    } 

}
