Question

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

我正在尝试以下文档中的简单示例：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（）内部创建的IndexRequest中？

是的，对我来说，这可能只是一些简单的疏忽，但是我已经努力了一段时间，希望得到一些帮助。

“缺失类型”是由于您的请求中缺少“ _doc”而引起的。可以将新的IndexRequest（“ posts”）更改为新的IndexRequest（“ posts”，“ _ doc”）。由于_types在Elastic 7.x.x中已删除，因此这将给出“已弃用”警告。
