JAX-RS 将实例注册为端点？

Question

我有一个与此类似的休息端点class：

@Path("/users")
public class Users {
    private final Database database;

    public Users(Database database) {
        this.database = database;
    }

    @GET
    @Path("/{id}")
    public Response Get(@PathParam("id") int id) {
        User user = this.database.get(id);
        return Response.ok(user).build();
    }
}

还有一个主要方法：

public class Main {
    public static void main(String[] args) {
        Database database = new SomeDBImplementation();
        Users users = new Users(database);
        
        HttpServer server = HttpServerFactory.create("http://localhost:8080");
        server.start();
    }
}

如何使服务器使用用户实例作为端点？我正在使用球衣服务器

您需要创建一个 ResourceConfig instance and then pass it to the HttpServerFactory.create(uri, resourceConfig) method. There are different implementations of ResourceConfig. The most basic one is the DefaultResourceConfig。要注册一个资源实例，你只需做

ResourceConfig config = new DefaultResourceConfig();
config.getRootResourceSingletons().add(users);
HttpServer server = HttpServerFactory.create(uri, config);
