org.springframework.dao.InvalidDataAccessApiUsageException: Required property docTypeVersion not found for class java.util.Optional
问题
在尝试使用DTO类选择Couchbase文档的某个部分时，出现以下错误：
org.springframework.dao.InvalidDataAccessApiUsageException: Required property docTypeVersion not found for class java.util.Optional; nested exception is java.lang.IllegalStateException: Required property docTypeVersion not found for class java.util.Optional
仓库类：
@Repository
@Scope("efatura_islem")
@Collection("gib_thread_process_non_verified")
public interface ThreadProcessCouchbaseRepository extends CouchbaseRepository<ThreadProcessCouchbaseEntity, String> {
@Query("SELECT meta(gtp).id AS __id , gtp.doc_type_version FROM gib_thread_process_non_verified AS gtp WHERE gtp.zip_path=$documentInstanceIdentifier")
ResponseDto selectApplicationResponseInfo(String documentInstanceIdentifier);
}
DTO类：
@Data
@Document
public class ResponseDto implements Serializable {
@Field("doc_type_version")
private String docTypeVersion;
}
文档如下：
{
"_class": "tr.gov.gib.efatura.core.entity.couchbase.ThreadProcessCouchbaseEntity",
"calc_hash": "6DB58D42B042F975A7E68464C8E18FE5",

"state_code": "1200",
"zip_path": "20548227-BDB9-4A7E-B873-FB7B8E3E2BCB.zip"
}
元数据如下：
{
"meta": {
"id": "20548227-BDB9-4A7E-B873-FB7B8E3E2BCB",
"rev": "1178-177a01ea20e300000000000002000000",
"expiration": 0,
"flags": 33554432,
"type": "json"
},
"xattrs": {}
}
以上是您提供的翻译部分。

When i try to select some part of couchbase document using a dto class,getting this error.
I tried several possible solutions like changing return type of query method Optional<ResponseDto> and getting from Optional class but did not fixed.I dont understand why it look for 'docTypeVersion' in Optional class.I did not try to get docTypeVersion from Optional class.

Repository class:
@Repository
@Scope("efatura_islem")
@Collection("gib_thread_process_non_verified")
public interface ThreadProcessCouchbaseRepository extends CouchbaseRepository<ThreadProcessCouchbaseEntity, String> {
@Query("SELECT meta(gtp).id AS __id , gtp.doc_type_version FROM gib_thread_process_non_verified AS gtp WHERE gtp.zip_path=$documentInstanceIdentifier")
ResponseDto selectApplicationResponseInfo(String documentInstanceIdentifier);
}
DTO class:

"org.springframework.dao.InvalidDataAccessApiUsageException: 类 java.util.Optional 找不到所需的属性 docTypeVersion；嵌套异常是 java.lang.IllegalStateException: 类 java.util.Optional 找不到所需的属性 docTypeVersion"
堆栈跟踪总是有用的 - 它可能会揭示框架为什么认为结果应该是一个 Optional。
此外，查询方法应该返回 List/Iterator/Optional 吗？以防没有匹配结果或有多个匹配结果？也许框架假设如果您只指定了 DTO，那么就应该返回 Optional

"org.springframework.dao.InvalidDataAccessApiUsageException: Required property docTypeVersion not found for class java.util.Optional; nested exception is java.lang.IllegalStateException: Required property docTypeVersion not found for class java.util.Optional"
The stack trace is always useful - it might shed some insight into why the framework thinks the result should be an Optional.
Also - shouldn't the query methods return a List/Iterator/Optional? In case there is zero (or more than one) matching results? Maybe the framework assumes Optional<DTO> if you have specified just DTO (just speculating).
