ElasticSearch 6.4：与RestHighLevelClient的映射

Question

Elastic现在正在更新他们的文档，以便使用带有Java的RestHighLevelClient。它还有一个映射API：

https://www.elastic.co/guide/en/elasticsearch/client/java-rest/master/java-rest-high-put-mapping.html

PUT /test
{
  "settings": {
    "analysis": {
      "filter": {
        "email": {
          "type": "pattern_capture",
          "preserve_original": 1,
          "patterns": [
            "([^@]+)",
            "(\\p{L}+)",
            "(\\d+)",
            "@(.+)",
            "([^-@]+)"
          ]
        }
      },
      "analyzer": {
        "email": {
          "tokenizer": "uax_url_email",
          "filter": [
            "email",
            "lowercase",
            "unique"
          ]
        }
      }
    }
  },
  "mappings": {
    "emails": {
      "properties": {
        "email": {
          "type": "string",
          "analyzer": "email"
        }
      }
    }
  }
}

还是RestHighLevelClient用于高性能操作，但对于初始配置，您可以自由地使用RestTemplate（Spring）或任何其他普通Java Rest客户端？

Answer 1

正如您在文档中所看到的：

PutMappingRequest request = new PutMappingRequest("twitter"); 
request.type("tweet"); 

您可以将定义设置为字符串来设置此请求的有效负载

request.source(
"{\n" +
"  \"properties\": {\n" +
"    \"message\": {\n" +
"      \"type\": \"text\"\n" +
"    }\n" +
"  }\n" +
"}", 
XContentType.JSON);

或者与您的属性甚至XContentBuilder映射。
