java - 将 Spring HATEOAS 添加到 pom.xml 失败

问题描述

所以我正在关注关于使用 spring boot 构建 Restful 服务的教程，我必须将 HATEOAS 依赖项添加到 pom.xml 但它不起作用！

这就是我得到的错误

在此处输入图像描述

而我的目标是使用无法导入的 Resource <> from import org.springframework.hateoas.Resource ！在此处输入图像描述

请帮忙

标签： javaspringhateoas

解决方案

Resource在 Spring Hateoas 1.0中已重命名为EntityModel，所以您正在寻找org.springframework.hateoas.EntityModel

来源：https ://docs.spring.io/spring-hateoas/docs/current/reference/html/#migrate-to-1.0.changes.representation-models ：

ResourceSupport/Resource/Resources/PagedResources 组的类从来没有真正感觉命名合适。毕竟，这些类型实际上并不体现资源，而是可以通过超媒体信息和可供性丰富的表示模型。以下是新名称与旧名称的映射方式：

ResourceSupport 现在是 RepresentationModel

资源现在是 EntityModel

Resources 现在是 CollectionModel

PagedResources 现在是 PagedModel
