我一直在尝试使用spring数据rest和spring boot设置rest服务。我按照https://spring.io/guides/gs/accessing-data-rest/的指南进行操作，但是没有在启动时创建预期的其余端点，并且在它们上调用get方法只会导致404。我可以使用RestController创建端点，但不能使用RepositoryRestResource创建端点。我正在使用Spring Boot 2和Hibernate 5.2，并以postgres作为后备数据存储区。我正在使用eclipse，并且尝试通过Eclipse中的Run Java Application运行应用程序，以及使用java -jar从Windows命令行运行它。输出和最终结果是相同的。有人知道我在做什么错以及我需要做什么才能使RepositoryRestResource创建预期的端点吗？我在下面放了示例代码，在底部有spring boot输出，但是首先这里是一些类似的问题以及我尝试过的事情：
此问题的答案已被接受，似乎表明它是实体扫描问题。但是，我已将EntityScan添加到应用程序中，这似乎没有帮助。 RepositoryRestResource with spring-boot CLI
此问题的答案是建议使用RestController将存储库包装在控制器类中，而不要使用RepositoryRestResource。我可以做到，但是我不想编写所有额外的代码，我宁愿RepositoryRestResource工作。 Clueless what I'm doing wrong setting up Spring Boot REST app
