@RepositoryRestResource 没有工作 Spring 启动 2.2.1.RELEASE。 while 运行 occurred error RegionRepository must only contain a single path segment

Question

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

数据休息class

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

主要运行class

发生错误

Answer 1

我几天前基于 2.2.2 创建了一个新项目，但遇到了同样的问题。

经过几次尝试，修复它的方法是在path和collectionResourceRel中使用相同的值。在您的情况下，请尝试在路径和 collectionResourceRel 中使用 "region"。

Answer 2

出现此问题是因为您使用“/”定义了路径。 Spring 不允许我们定义像“/api/v1/my_entity”这样的组合路径。只需从您的路径中删除“/”即可。

Answer 3

您必须在 @RepositoryRestResource 中提及 path='endpoint name' 而无需使用“/”。您必须使用 @RepositoryRestResource(path = "region")，它是直接 spring MVC 在 /region[= 创建 RESTful 端点14=]
