用JAVA API把映射放到ElasticSearch中

Question

我想通过JAVA API为字段设置映射，但失败了。以下是详细信息：

我的数据结构是：

{
"mje-test-execution-id": "464b66ea6c914ddda217659c84a3cb9d",
"jvm-free-memory": 315245608,
"jvm-total-memory": 361758720,
"system-free-memory": 0,
"jvm-max-memory": 7600078848,
"system-total-memory": 34199306240,
"memory-time-stamp": "2020-03-12T05:12:16.835Z",
"mje-host-name": "CN-00015345",
"mje-test-suite-name": "SCF Test no mje version",
"mje-version": "1.8.7771-SNAPSHOT",
"mje-test-artifact-id": "msran-regression-tests",
"mje-test-version": "1.8.7771-SNAPSHOT",
"stp-id": "vran-stp",
"mje-test-location": {
"lat": 58.41,
"lon": 15.62
}
}

我想做的是：将"mje测试位置"类型设置为"geo_point">

我的代码片段：

public void postMapping(String indexName, String field, String type) throws IOException {
GetIndexRequest request = new GetIndexRequest(indexName);
boolean exists = client.indices().exists(request, RequestOptions.DEFAULT);
if (!exists) {
LOGGER.info("index {} does not exist. Now to post mapping.", indexName);
PutMappingRequest putMappingRequest = new PutMappingRequest(indexName);
XContentBuilder builder = XContentFactory.jsonBuilder();
builder.startObject();
{
builder.startObject("properties");
{
builder.startObject(field);
{
builder.field("type", type);
}
builder.endObject();
}
builder.endObject();
}
builder.endObject();
putMappingRequest.source(builder);
//
AcknowledgedResponse putMappingResponse = client.indices().putMapping(putMappingRequest,
RequestOptions.DEFAULT);
boolean acknowledged = putMappingResponse.isAcknowledged();
if (acknowledged) {
LOGGER.info("Succeed to put mapping: field:{}, type: {}", field, type);
}
}
LOGGER.info("Fail to put mapping due to index {} already exist, ", indexName);
}

错误信息：

15:59:54.397 [main] DEBUG org.elasticsearch.client.RestClient - request [PUT http://seliiuapp00269.lmera.ericsson.se:9208/mje-scf-v2-20200313-post/_mapping?master_timeout=30s&timeout=30s] returned [HTTP/1.1 400 Bad Request]
org.elasticsearch.ElasticsearchStatusException: Elasticsearch exception [type=action_request_validation_exception, reason=Validation Failed: 1: mapping type is missing;]

ElasticSearch JAVA API版本：<elasticsearch.rest.high.level.client>7.0.0</elasticsearch.rest.high.level.client>

Answer 1

您需要指定这样的文档类型：

putMappingRequest.type("_doc");

还需要在这里指定字段的类型：

builder.field("type", type);

如：("type", "text")或("type", "long")、("type", "date")。。。。。。

你可以在这里看到数据类型

Answer 2

我会发布@Mincong的评论作为答案，因为我导入了从github搜索中发现的错误导入：

你班的全名是什么"PutMappingRequest"：org.lasticsearch.action.admin.indices.mapping.put.PutMappingRequest还是org.lasticearch.client.indices.PutMappingRequest？你应该用第二个。
