Question

我已经看到了类似的问题和解决方案，但仍然无法找到我的解决方案。

我以编程方式启动Jetty服务器并使用Guice将Jersey挂钩。当我尝试访问我的Jersey资源时，我得到404。

public class TestService {

    public static void main(String[] args) throws Exception {
        Server server = new Server(8080);

        ServletContextHandler context = new ServletContextHandler();
        context.setContextPath("/");
        server.setHandler(context);

        final Injector injector = Guice.createInjector(new MyServletModule());
        FilterHolder guiceFilter = new FilterHolder(injector.getInstance(GuiceFilter.class));
        context.addFilter(guiceFilter, "/*", EnumSet.allOf(DispatcherType.class));
        context.addEventListener(new GuiceServletContextListener() {
            @Override
            protected Injector getInjector() {
                return injector;
            }
        });

        server.start();
        server.join();
    }
}

class MyServletModule extends ServletModule {
    @Override
    protected void configureServlets() {
        bind(GuiceContainer.class);

        Map<String, String> parameters = Maps.newHashMap();
        parameters.put(PackagesResourceConfig.PROPERTY_PACKAGES, "com.test");
        parameters.put(JSONConfiguration.FEATURE_POJO_MAPPING, "true");
        serve("/*").with(GuiceContainer.class, parameters);
    }
}

我的资源：

@Singleton
@Path("/")
public class MyResource {

    @GET
    public String sayhello() {
        return "hello";
    }
}

我可以看到资源正在日志中加载：

INFO: Root resource classes found:
  class com.test.MyResource

但我在加载404时得到http://localhost:8080/。我还尝试将资源映射到其他网址fx /web，但它仍然是404。

Answer 1

您需要一个默认的servlet。尝试添加

context.addServlet(DefaultServlet.class, "/");

添加Guice过滤器后。

Jetty + Guice + Jersey在访问资源时提供404
