Spring数据将所有相关资源反序列化为_embedded

Question

我正在将Spring Data Rest与JPA Repository以及我的实体（客户）与其他实体（包括其自身）的关联一起使用。下面的示例是一个自引用关联，尽管我也看到了其他关联的相同行为。

我希望在请求客户资源时

  

/ api / customer / 12345

响应JSON将“仅”具有到关联资源的链接，但是我看到关联资源也被反序列化为“ _embedded”

“ _ embedded”反序列化是默认行为还是我配置错误？

@RepositoryRestResource(path = "customer")
public interface CustomerRepository extends PagingAndSortingRepository<Customer, String> {

@RestResource
    Optional<Customer> findById(String id);

}

@Entity
@Table(name = "CUSTOMER")
@Data
@JsonIgnoreProperties({ "hibernateLazyInitializer", "handler" })
@JsonInclude(Include.NON_NULL)
public class Customer implements Serializable {

@Id
private String customerid;

private String name;

@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "REFERENCE_CUSTOMER")
private Customer referenceCustomer;

}

localhost：8080 / api / customer / 12345

{
name : "N12345",
    _embedded : {
    referenceCustomer : {
    name : "R787657"
    }
},
"_links": {
        "self": {
            "href": "http://localhost:8080/api/customer/12345"
        },
        "customer": {
            "href": "http://localhost:8080/api/customer/12345"
        },
        "referenceCustomer": {
            "href": "http://localhost:8080/api/customer/12345/referenceCustomer"
        }
    }
}
