我有一个Elasticsearch文档的批量索引，该索引因AbstractMethodError失败一次。
此代码每隔两次运行一次，这只是服务器重新启动后的第一次。
public boolean bulkSave(List<Pair<String, T>> entities, Class<T> type, String indexName) {
try {
template.bulkIndex(entities.stream().map(entity -> toIndexQuery(entity, indexName)).collect(Collectors.toList()));
template.refresh(type);
return true;
} catch (ElasticsearchException e) {
log.error(e.getMessage(), e);
return false;
}
}
private IndexQuery toIndexQuery(Pair<String, T> keyValue, String indexName) {
IndexQueryBuilder builder = new IndexQueryBuilder().withId(keyValue.getFirst()).withObject(keyValue.getSecond());
if (Objects.nonNull(indexName)) {
return builder.withIndexName(indexName).build();
}
return builder.build();
}
我的文档声明如下：
@Data
@Builder
@AllArgsConstructor
@NoArgsConstructor
@FieldDefaults(level = AccessLevel.PRIVATE)
@Document(indexName = "myIndex", type = "myType")
public class MyPojo {
@Id
String id;
// bunch of other fields, of types UUID, ENUM, and List<String>
@JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "yyyy-MM-dd'T'HH:mm:ss.SSSZ")
Date updatedAt;
@Version
Long version;
}
执行它时，出现以下异常：

This post指出版本不兼容，可能是这种情况，因为我们仍在Spring 5上使用Elasticsearch 2.4，并且无法更新，但是，我无法弄清问题所在，所以远。
此外，如果它是版本不兼容的话，我希望它永远不会起作用，并且除了第一个版本以外，它不会每次都起作用。
任何想法可能是这种行为的原因吗？我只说一次失败。可能是尚未加载某些东西（驱动程序？）吗？这里涉及的任何本机都可能无法加载吗？
启动服务器后，我试图等待一段时间，以防万一需要花一些时间初始化并且无法正常工作。我还实现了重试，以防万一第一次失败，并且超时还会重试几次。那也不起作用。
我现在很茫然。关于下一步要检查的任何想法都很棒。谢谢
