我用这个样本开始了我的项目https://github.com/spring-projects/spring-boot/tree/master/spring-boot-samples/spring-boot-sample-data-ldap.

但是当我添加依赖spring-boot-starter-data-rest时，我有PerstientEntity不能为null！错误，即使我在application.properties中添加了spring.data.rest. detationStrategy=annotated（如何禁用Spring Data REST存储库的默认公开？和https://github.com/spring-projects/spring-ldap/issues/373）。如果我在人员存储库上尝试这个@RepositoryRestResource（导出=false），我也会遇到同样的错误。

是bug还是我错过了什么？

谢啦

Person.java：

package sample.data.ldap;

import javax.naming.Name;

import org.springframework.ldap.odm.annotations.Attribute;
import org.springframework.ldap.odm.annotations.Entry;
import org.springframework.ldap.odm.annotations.Id;

@Entry(objectClasses = { "person", "top" })
public class Person {

@Id
private Name dn;

@Attribute(name = "telephoneNumber")
private String phone;

@Override
public String toString() {
    return String.format("Customer[dn=%s, phone='%s']", this.dn,  this.phone);
 }
}

PersonRepository.java：

package sample.data.ldap;

import org.springframework.data.ldap.repository.LdapRepository;

public interface PersonRepository extends LdapRepository<Person> {

Person findByPhone(String phone);

}

错误：
