DuplicateKeyException wile bean 创建 Spring-data

Question

我有一个带有 @Document(collection = "excursionAttendees") 注释的 POJO (ExcursionAttendee) 注释，并且有一个没有任何自定义方法的存储库类。

public interface ExcursionAttendeeRepository extends MongoRepository<ExcursionAttendee, String>

spring-data-mongodb 在 1.7.0.RELEASE 上并使用 mongo-java-driver 3.0.0 对 mongodb 3.0 。当应用程序正在部署时，会引发以下异常。

Error creating bean with name 'excursionAttendeeRepository': Invocation of init method failed; nested exception is com.mongodb.DuplicateKeyException: Write failed with error code 11000 and error message 'null'

我一直在互联网上搜索，但找不到任何原因。这是 bean 创建阶段，它不会尝试执行任何更新或 upsert 来导致索引出现任何问题。这里有什么问题？

Answer 1

升级 mongo java 驱动程序后，它给了我足够的证据来发现问题。

Write failed with error code 11000 and error message 'exception: E11000 duplicate key error index: veip.guardians.$school._id dup key: { : null }'

嵌入对象中有@Index注解

@Id
@Indexed(unique=true)
private String id;

但是在数据库中，嵌入对象的这个 id 属性对于所有文档都是空的。这解释了异常。
