Question

在这个项目中： https://github.com/jstemen/json-to-db

我已经能够通过以下方式将Jersey 2链接到Spring数据：

public class MyApplication extends ResourceConfig {
/**
* Register JAX-RS application components.
*/
    @Inject
    public MyApplication(ServiceLocator serviceLocator) {
        //ToDo: find a way to have Jersey better interface with Spring

        //Pull bean out of Spring
        ApplicationContext ctx = new AnnotationConfigApplicationContext(AppConfig.class);
        Rest rest = ctx.getBean(Rest.class);

        //Link pulled out Spring bean Jersey's DI framework
        DynamicConfiguration dc = Injections.getConfiguration(serviceLocator);
        Injections.addBinding(
                Injections.newBinder(rest)
                        .to(Rest.class),
                dc);

        dc.commit();//Don't forget to commit

        register(Rest.class); //Mark Rest class as an REST endpoint to Jersey
    }
}

然而，它并不是很有说服力。无论如何我可以让我的Web.xml加载Jersey 2和Spring并将Spring bean自动映射到Jersey REST端点吗？如果有人分支我的回购并分享它以证明如何做得更好，那将是非常棒的！

Jersey 2附带了与Spring集成的扩展，请参阅https://jersey.java.net/documentation/latest/spring.html

这很好用，我们的Spring组件通过字段注入直接自动连接到我们的资源中，如下所示：

@Component
@Path("/")
public class FooResource {
    @Autowired
    private SomeComponent someComponent;

    protected FooResource() {}

    @GET
    public String bar() {
        return "foobar";
    }
}

在您的ResourceConfig扩展课程中，您只需执行register(FooResource.class)！有关详细信息，请参阅文档和Spring DI example。

我怎样才能将Spring Data与Jersey 2联系起来？
