java - @RepositoryRestResource 在 Spring Boot 2.2.1.RELEASE 中不起作用。运行时出现错误 RegionRepository 必须只包含一个路径段

Question

@RepositoryRestResource(path = "/region", collectionResourceRel = "list", excerptProjection = CustomRegion.class)
public interface RegionRepository extends JpaRepository<Region, Integer> {
}

数据休息类

@SpringBootApplication
public class ProfUzApplication {
    public static void main(String[] args) {
        SpringApplication.run(ProfUzApplication.class, args);
    }
}

主跑类

发生错误

Answer 1

您必须在@RepositoryRestResource 中提及 path='endpoint name' 而不使用 '/'。您必须使用 @RepositoryRestResource(path = "region" )，它是直接的 spring MVC 在 创建 RESTful 端点/region
