java - Elasticsearch Java API 7.0 批量插入尝试基本示例，抛出错误

Question

Java 1.8，Elasticsearch 低级和高级 Rest 客户端 7.0.0

我正在尝试此处文档中的简单示例:Bulk API

BulkRequest bulkRequest = new BulkRequest();
request.add(new IndexRequest("posts").id("1")  
    .source(XContentType.JSON,"field", "valueString"));
 // not working


Map<String, Object> doc1 = new HashMap<>();
doc1.put("property", "value");
request.add(new IndexRequest("posts").id("1").source(doc1);
 // this is easy to add as a single IndexRequest, but not working here

 BulkResponse bulkResponse = this.getClient().bulk(request, RequestOptions.DEFAULT);
 // this is the line throwing the error, straight from the docs

错误:

{"error":{"root_cause":[{"type":"action_request_validation_exception","reason":"Validation Failed: 1: type is missing;"}],"type":"action_request_validation_exception","reason":"Validation Failed: 1: type is missing;"},"status":400}

那么缺少什么类型？我尝试添加映射，将 opType("create") 添加到在 request.add() 中创建的 IndexRequest？

是的，这可能是我的一些简单疏忽，但我已经为此努力了一段时间，希望能得到一些帮助。

Answer 1

“缺少类型”的出现是因为您的请求中缺少“_doc”。将 new IndexRequest("posts") 更改为 new IndexRequest("posts","_doc") 可能会起作用。这将给出“已弃用”警告，因为 _types 在 Elastic 7.x.x 中已被删除。
