如何在grizzly上使用jersey 2.0 guice

我想在Grizzly上使用Guice+Jersey 2.0。根据这一讨论，目前没有Jersey2的直接Guice集成，但可以使用HK2作为桥梁来实现。我还检查了Github中的示例项目。该项目使用码头实施

但我的问题是在Grizzly中实现它。在码头上，它是这样使用的

  @Inject
public MyApplication(ServiceLocator serviceLocator) {
    // Set package to look for resources in
    packages("example.jersey");

    System.out.println("Registering injectables...");

    GuiceBridge.getGuiceBridge().initializeGuiceBridge(serviceLocator);

    GuiceIntoHK2Bridge guiceBridge = serviceLocator.getService(GuiceIntoHK2Bridge.class);
    guiceBridge.bridgeGuiceInjector(Main.injector);

}

我在grizzly上的问题是，如何获取这个serviceLocator对象

谢谢。

我已经在这里创建了示例

Grizzly初始化代码如下所示：

final URI uri = UriBuilder.fromUri("http://127.0.0.1/")
        .port(8080).build();

// Create HttpServer
final HttpServer serverLocal = GrizzlyHttpServerFactory.createHttpServer(uri, false);

// Create Web application context
final WebappContext context = new WebappContext("Guice Webapp sample", "");

context.addListener(example.jersey.Main.class);

// Initialize and register Jersey ServletContainer
final ServletRegistration servletRegistration =
        context.addServlet("ServletContainer", ServletContainer.class);
servletRegistration.addMapping("/*");
servletRegistration.setInitParameter("javax.ws.rs.Application",
        "example.jersey.MyApplication");

// Initialize and register GuiceFilter
final FilterRegistration registration =
        context.addFilter("GuiceFilter", GuiceFilter.class);
registration.addMappingForUrlPatterns(EnumSet.allOf(DispatcherType.class), "/*");

context.deploy(serverLocal);

serverLocal.start();

添加依赖项

compile group: "org.glassfish.hk2", name: "guice-bridge", version: "2.4.0"

创建特征

public class GuiceFeature implements Feature {

    @Override
    public boolean configure(FeatureContext context) {
        ServiceLocator serviceLocator = ServiceLocatorProvider.getServiceLocator(context);

        GuiceBridge.getGuiceBridge().initializeGuiceBridge(serviceLocator);
        GuiceIntoHK2Bridge guiceBridge = serviceLocator.getService(GuiceIntoHK2Bridge.class);

        Injector injector = Guice.createInjector(new AbstractModule() {
            @Override
            protected void configure() {
                bind(YYY.class).to(ZZZ.class);
            }
        });
        guiceBridge.bridgeGuiceInjector(injector);

        return true;
    }
}

寄存器特征

ResourceConfig resourceConfig = new ResourceConfig();
resourceConfig.register(GuiceFeature.class);

这个示例工作得很好，但是如何注册ContainerResponseFilter呢？如果类路径上没有

ServiceLocatorProvider

，您还可以得到一个

ServiceLocator

实例，如下所示：

InjectionManager InjectionManager=InjectionManagerProvider.getInjectionManager（上下文）；ServiceLocator ServiceLocator=injectionManager.getInstance（ServiceLocator.class）
