Spring Boot2中的RepositoryRestResource批注不可访问

Question

我似乎不能让@RepositoryRestResource在我的简单课程中工作。下面是我的代码在GitHub上的位置：

https://github.com/txt8888/SB2-RepositoryRestResource

基本上，

部门实体：(我知道数据库连接是有效的)

@Data
@AllArgsConstructor
@NoArgsConstructor
@Entity
@Table(name = "departments")
public class Department {

    @Id
    private String id;
    private String name;
}

和存储库：

@CrossOrigin
@RepositoryRestResource(collectionResourceRel = "departments",
                        path = "departments")
public interface DepartmentRepository extends JpaRepository<Department, String> {
}

还有我的pom.xml

</project>

当我点击http://localhost:8080/departments时，它返回404Not found。

http://localhost:8080/actuator/mappings也不显示端点。

我是不是错过了什么明显的东西？

Answer 1

我发现了问题所在。我忘了包括这个依赖项：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-rest</artifactId>
</dependency>

我以前有过这样的依赖：

<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-rest-core</artifactId>
    <version>2.6.10.RELEASE</version>
</dependency>
