Java Dropwizard-Can'；t使用Guice Injector.getIntance（）注册jersey资源

我在以前的方法中成功地使用了这个设置，所以我现在可能做错了什么。我主要使用Guice作为其AOP部分

pom.xml的相关章节：

    </dependency>

注册资源的文件：

public class BucService extends Application<BucConfiguration> {
    public static void main(String[] args) throws Exception {
        new BucService().run(args);
    }

    @Override
    public void initialize(Bootstrap<BucConfiguration> bootstrap) {
        //bootstrap.setName("hello-world");
    }

    @Override
    public void run(BucConfiguration configuration,
                    Environment environment) {
        final String template = configuration.getTemplate();
        final String defaultName = configuration.getDefaultName();
        environment.jersey().register(new HelloWorldResource(template, defaultName));

        Injector injector = Guice.createInjector(new BaseBindingModule ());
        environment.jersey().register(injector.getInstance(CabResource.class)); // this does not work
      //  environment.jersey().register(new CabResource()); // this works
    }
}

根据评论进一步澄清：

我确实使用injector.getInstance（CabResource.class）获得了一个实例

例如：

CabResource a = new CabResource();
CabResource b = injector.getInstance(CabResource.class);

a.getCheapestCabs(); 
b.getCheapestCabs();

这两个电话都有效。

您考虑过使用吗

如果没有错误，添加错误日志可能会有所帮助。它只是不注册。我可以很好地运行这个罐子。我就是无法访问API。它说404找不到。我仍然添加了运行jar.injector.getInstance（CabResource.class）时得到的输出，这是否会返回任何东西？它可能不会返回任何东西？因为它还没有在Guice注册？我想我读得有点太快了。尝试将资源绑定到模块中，我们将对此进行研究。谢谢虽然在另一份工作的监督下，我成功地运行了相同的设置，而不需要这些库。因此，我真的希望在不使用其他外部库的情况下解决这个问题，并用当前代码找出问题所在。
@Path("/cabs")
@Produces(MediaType.APPLICATION_JSON)
public class CabResource {

    @Inject
    CabManager manager;


    public CabResource() {
    }

    @GET
    @Path("price")
    @Produces(MediaType.APPLICATION_JSON)
    public List<PriceEstimate> getCheapestCabs() {

        return manager.callB();
    }

    @GET
    @Produces(MediaType.APPLICATION_JSON)
    @SendCrashReport
    public List<PriceEstimate> getNearestCabs(@Context UriInfo uriInfo) {

        return manager.callA();
      }

}
