FeignClient始终返回空结果

Question

我已经在这个问题上投入了很多时间。我有一个spring数据后端，因此它返回了hateoas对象。我正在尝试将后端的结果提取到Resource对象中。发布数据的工作原理也将返回发布的对象。但是，在获取对象列表时，它总是返回一个空对象。

FeignClient

@FeignClient(name="products", url = "http://localhost:8084")
public interface ProductClient {

    @GetMapping("/products")
    Resources<Product> getProducts();

    @RequestMapping(method = RequestMethod.POST, value = "/products")
    Resource<Product> addProduct(Product product);
}

RestController

@RestController
@RequestMapping("products")
public class ProductController {

    private ProductClient productClient;

    @Autowired
    public ProductController(ProductClient productClient) {
        this.productClient = productClient;
    }

    @GetMapping
    public Resources<Product> getProduct(){
        Resources<Product> productResources = productClient.getProducts();
        return productResources;
    }

    @PostMapping
    public Resource<Product> addProduct(@RequestBody Product product){
        Resource<Product> product2 = productClient.addProduct(product);
        return product2;
    }
}
