[spring-projects/spring-boot]Spring 反应式、本机和 Hateoas 的 EntityModel 实例化问题

你好，

这是我的配置：Springboot版本3.1.1（反应式），原生一代，MacOS ARM-M1，OpenJDK运行时环境GraalVM 17.0.7+8.1

编译时一切正常gradle bootJar

当我使用本机模式 ( gradle nativeCompile) 进行编译并运行应用程序时，我得到以下堆栈跟踪。

完整源代码可在此处获取：https://github.com/operrin/native-hateoas

谢谢

使用 WebFlux.Fn 意味着方法签名中没有有关将序列化为 JSON 的类型的信息。您可以使用@RegisterReflectionForBinding来提供有关需要序列化为 json 的类型的信息。例如，添加@RegisterReflectionForBinding(EntityModel.class)到getIntervenantById应该可以解决问题：

$ http :8082/intervenants 
HTTP/1.1 200 OK
Content-Length: 175
Content-Type: application/json

{
    "content": [
        {
            "id": "de7d9052-4961-4b4f-938a-3cd12cbe1f82",
            "links": [
                {}
            ],
            "nom": "Marchal"
        },
        {
            "id": "425e7701-02c6-4de3-9333-a2459eece1c8",

            "nom": "Dubois"
        }
    ],
    "links": [
        {}
    ]
}

这将在 Spring HATEOAS 2.0.5、2.1.1 和 2.2 M1 中修复。即，它将包含在下一个 Spring Boot 3.x 错误修复版本中。已验证修复以使原始再现器正常工作。

谢谢。为了完全正确，我必须添加以下注释： @RegisterReflectionForBinding({Link.class, EntityModel.class})

以EntityModel.class避免 MapSuppressingUnwrappingSerializer 异常。并Link.class获取链接的正确值（否则，它们是空的）

我必须对您的示例项目发出什么请求才能触发缺少的元数据Link？HypermediaTypeAotProcessor实际上应该已经添加了该元数据，并且我们有 AOT 冒烟测试，显示链接在本机图像中正确呈现。 ？

链接是正确的。

使用@RegisterReflectionForBinding(EntityModel.class)，当用 编译时gradle nativeCompile，我得到：

    "content": [

            ]
        }
    ],
    "links": [
        {}
    ]
}

链接为空。

使用@RegisterReflectionForBinding({Link.class,EntityModel.class})，当用 编译时gradle nativeCompile，链接是正确的。

谢谢，我去看看。

您确定是Link，而不是Links（尾随 s）吗？看来问题是Links未注册反射和您的项目未使用正确的超媒体媒体类型而仅使用的组合application/json。这将导致EntityModel按原样渲染，因此我们为 HAL 等官方超媒体媒体类型设置的自定义 Jackson 指令将生效。我只能建议切换到其中一种，因为渲染任何内容，但官方不支持。

我将继续并Links在 spring-projects/spring-hateoas#1981 （以及相应的后端口）的上下文中增强反射注册。但话又说回来，如果您愿意返回application/hal+json或任何其他受支持且正确指定的超媒体类型，您应该会看到此工作。

谢谢。它适用于Link.class.

关于MediaType，我只是尝试以下修改：

    @RegisterReflectionForBinding(EntityModel.class)
    public Mono<ServerResponse> getIntervenantById(ServerRequest request) {
        var collectionLink = Link.of(deleteIdInUri(request.uri().toString(), request.pathVariable("id")))
                .withRel("collection");
        var selfLink = Link.of(request.uri().toString()).withSelfRel();
        return this.is.getIntervenant(request.pathVariable("id"))
                .flatMap(r -> Mono.just(EntityModel.of(r, selfLink, collectionLink)))
                .flatMap(r -> ServerResponse.ok().contentType(MediaTypes.HAL_JSON).bodyValue(r))
                .switchIfEmpty(ServerResponse.notFound().build());
    }

结果是空链接。

抱歉，我仔细阅读了您的消息，并且我添加了配置类并使用了注释@EnableHypermediaSupport，并且链接正确呈现。

我很抱歉

不用道歉。这非常有帮助。我刚刚意识到 Spring HATEOAS 自动配置在 Web.fn 场景中未激活。我想知道是否应该使用位于 WebFlux 工件中的触发器类型来解决这个问题？ /抄送@wilkinsona

重新阅读 #16020 中的对话后，我想我将继续将基本 Spring HATEOAS 类型的 AOT 反射提示生成与涵盖生成单个媒体类型的 Jackson 模型类型的生成分开。这样，即使用户不想使用正确的、受支持的超媒体类型，我们也可以让 HATEOAS 在 GraalVM 上开箱即用。即使我们不建议这样做，我认为合理的工作也比部分失败要好。

@EnableHypermediaSupport我还将在参考文档中提到需要明确使用WebFlux / Web.fn 设置。

为了结束这个问题，我更新了 spring-projects/spring-hateoas#1981 的修复，以确保所有基本的 HATEOAS 类型都注册为反射。也就是说，我仍然无法为您的 Web.fn 设置提供正确的 HAL 渲染。我得单独调查一下。
