我在Angular 2.0.0中遇到了TestBed的问题

    beforeEach( async(() => {
        TestBed.configureTestingModule({
            declarations: [
                SomethingComponent
            ]
        }).compileComponents(); // compile template
    }));

    beforeEach(() => {
        fixture = TestBed.createComponent(SomethingComponent);
        comp = fixture.componentInstance;
    });

    it('test', async(() => {
        fixture.detectChanges();
        expect(true)
    }));

给定组件:

@Component({
    templateUrl: 'app/components/something/something.component.html'
})

我收到错误:

Firefox 48.0.0 (Mac OS X 10.11.0)
Failed: Uncaught (in promise): Failed to load app/components/something/something.component.html

我想这可能是因为配置没有正确设置.我正在使用gulp将TypeScript预编译为JavaScript,我有以下项目结构:

|_ grails-app
|_ frontend
  |_ angular
    |_ app
    |    |_ components
    |    |     |_ something
    |    | …

我有这条路线:

routes.MapHttpRoute(
                name: "DefaultApi",
                routeTemplate: "api/{controller}/{id}/{myparam}",
                defaults: new { id = RouteParameter.Optional, myparam = RouteParameter.Optional }
            );

'id'应该是可选的,'myparam'应该是可选的,但如果'myparam'被设置,'id'不能是可选的.我该如何配置？

我按照这里提供的教程用给定值替换路径参数,并运行下面给出的示例代码

import org.glassfish.jersey.uri.UriTemplate;

import javax.ws.rs.core.UriBuilder;
import java.net.URI;
import java.util.HashMap;
import java.util.Map;

public class Demo {
    public static void main(String[] args) {
        String template = "http://example.com/name/{name}/age/{age}";
        UriTemplate uriTemplate = new UriTemplate(template);
        String uri = "http://example.com/name/Bob/age/47";
        Map<String, String> parameters = new HashMap<>();

        // Not this method returns false if the URI doesn't match, ignored
        // for the purposes of the this blog.
        uriTemplate.match(uri, parameters);
        System.out.println(parameters);
        parameters.put("name","Arnold");
        parameters.put("age","110");

        UriBuilder builder = UriBuilder.fromPath(template);
        URI output = builder.build(parameters);
        System.out.println(output.toASCIIString());


    }
}

但是当我编译代码时,它给了我这个错误
