如何冲洗数据到弹簧数据弹性搜索
我运行此测试箱
Envelope envelope = new Envelope();
envelope.setId("1");
Envelope saved = envelopeRepository.save(envelope);
assertThat(saved.getId()).isEqualTo("1");
保存，并且信封是同一对象/参考！因此，即使索引不正确，测试仍然通过！如何解决此问题？
org.elasticsearch.client.RestClient - request [HEAD http://localhost:9200/null?ignore_throttled=false&ignore_unavailable=false&expand_wildcards=open%2Cclosed&allow_no_indices=false]
I run this testcase
Envelope envelope = new Envelope();
envelope.setId("1");
Envelope saved = envelopeRepository.save(envelope);
assertThat(saved.getId()).isEqualTo("1");
saved and envelope are the same object/reference! So even when the index is incorrect, the test still passes! How to fix this issue?

为什么保存的实体应该是一个新对象？保存时，Elasticsearch不会返回文档，因此无需在此处创建一个新对象。
Spring Data Elasticsearch的操作是用索引操作返回的信息更新此对象：
id如果该对象尚未在对象上设置，但primary_term如果实体具有此类属性，如果索引失败，则会引发异常。
你是什么意思
， head 请求对此有何处理？
Why should the saved entity be a new object? Elasticsearch does not return a document when saving, so there is no need to create a new object here.
What Spring Data Elasticsearch does is update this object with the information returned from the index operation:
idif it was not already set on the object but was created by Elasticsearchseq_noandprimary_termif the entity has such a propertyIf the indexing fails, an exception is thrown.
What do you mean with
And what has the HEAD request do do with this?
