Spring Data Elasticsearch - 注册自定义分析器

我正在尝试在我的应用程序中使用ElasticSearch进行全文搜索，并且现在我正在尝试使用自动完成分析器：

{
    "settings": {
        "number_of_shards": 1,
        "analysis": {
            "filter": {
                "autocomplete_filter": {
                    "type": "edge_ngram",
                    "min_gram": 1,
                    "max_gram": 20
                }
            },
            "analyzer": {
                "autocomplete": {
                    "type": "custom",
                    "tokenizer": "standard",
                    "filter": [
                        "lowercase",
                        "autocomplete_filter"
                    ]
                }
            }
        }
    }
}

由于我的应用是使用Spring构建的，我决定使用Spring-data-elasticsearch，并按照以下方式映射实体：

@Document(indexName = "estabelecimento")
@Setting(settingPath = "/elasticsearch/autocomplete-analyser.json")
public class ESEstabelecimento {

    private Long id;
    @Field(type = FieldType.String, indexAnalyzer = "autocomplete")
    private String nome;
    private String razaoSocial;
    private String tipoEstabelecimento;
    @Field(type = FieldType.Object)
    private ESCidade cidade;
}

然而，Elasticsearch没有加载自定义分析器：

[DEBUG] org.elasticsearch.action.admin.indices.mapping.put - [Magus] 在索引[[estabelecimento]]，类型[esestabelecimento]上放置映射失败 org.elasticsearch.index.mapper.MapperParsingException: 找不到字段[nome]的分析器[autocomplete] at org.elasticsearch.index.mapper.core.TypeParsers.parseField(TypeParsers.java:220) ~[elasticsearch-1.5.2.jar:na] at org.elasticsearch.index.mapper.core.StringFieldMapper$TypeParser.parse(StringFieldMapper.java:153) ~[elasticsearch-1.5.2.jar:na] at org.elasticsearch.index.mapper.object.ObjectMapper$TypeParser.parseProperties(ObjectMapper.java:290) ~[elasticsearch-1.5.2.jar:na] at org.elasticsearch.index.mapper.object.ObjectMapper$TypeParser.parseObjectOrDocumentTypeProperties(ObjectMapper.java:214) ~[elasticsearch-1.5.2.jar:na] at org.elasticsearch.index.mapper.object.RootObjectMapper$TypeParser.parse(RootObjectMapper.java:136) ~[elasticsearch-1.5.2.jar:na] at org.elasticsearch.index.mapper.DocumentMapperParser.parse(DocumentMapperParser.java:211) ~[elasticsearch-1.5.2.jar:na] at org.elasticsearch.index.mapper.DocumentMapperParser.parseCompressed(DocumentMapperParser.java:192) ~[elasticsearch-1.5.2.jar:na] at org.elasticsearch.index.mapper.MapperService.parse(MapperService.java:434) ~[elasticsearch-1.5.2.jar:na] at org.elasticsearch.cluster.metadata.MetaDataMappingService$4.execute(MetaDataMappingService.java:505) ~[elasticsearch-1.5.2.jar:na] at org.elasticsearch.cluster.service.InternalClusterService$UpdateTask.run(InternalClusterService.java:365) ~[elasticsearch-1.5.2.jar:na] at org.elasticsearch.common.util.concurrent.PrioritizedEsThreadPoolExecutor$TieBreakingPrioritizedRunnable.runAndClean(PrioritizedEsThreadPoolExecutor.java:188) [elasticsearch-1.5.2.jar:na] at org.elasticsearch.common.util.concurrent.PrioritizedEsThreadPoolExecutor$TieBreakingPrioritizedRunnable.run(PrioritizedEsThreadPoolExecutor.java:158) [elasticsearch-1.5.2.jar:na] at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) [na:1.8.0_77] at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) [na:1.8.0_77] at java.lang.Thread.run(Thread.java:745) [na:1.8.0_77] [ERROR] org.springframework.data.elasticsearch.repository.support.AbstractElasticsearchRepository - 加载Elasticsearch节点失败：org.elasticsearch.index.mapper.MapperParsingException: 找不到字段[nome]的分析器[autocomplete]

我无法确定问题的原因，不知道分析器是否无效或者Elasticsearch是否找到了autocomplete-analyser.json文件。该如何解决？

你在尝试时是否删除了索引？仅在索引不存在时才会创建该索引。如果索引已经存在，则不会更新设置。首先删除索引，让 Spring 重新创建它。你也可以使用 GET /estabelecimento/_settings 检查设置，也许可以提供一些见解。 - Jettro Coenradie

问题已解决

经过一些研究，我发现问题是由以下声明引起的：

@Bean
public ElasticsearchOperations elasticsearchTemplate(Client client) {
    return new ElasticsearchTemplate(client, new CustomEntityMapper());
}

我移除了这个声明，然后它开始获取配置。

我曾经遇到过类似的问题，这可能是由于多种原因引起的：

确保您的json文件位于与settingPath中提到的位置相同，并且被正确读取。如Richa在上面所说，可以通过从json中删除分析器并测试创建的分片数量来验证此操作。
如果位置正确但仍然无法读取json文件，则只需检查您是否在模型类中添加了@Document（indexName =“indexName”，createIndex = false）注释，然后从文档注释中简单地删除createIndex = false，然后再次尝试。
始终记得删除旧索引，然后再次测试。

我猜你需要从JSON文件中删除字段"settings":，只保留内容。

不要使用：

{
"settings": {
    ....
   }
}

只需使用：

：

{ 
"index": {
"number_of_shards": 1,
"analysis": {
  "filter": {
    "autocomplete_filter": {
      "type": "edge_ngram",
      "min_gram": 1,
      "max_gram": 20
    }
  },
  "analyzer": {
    "autocomplete": {
      "type": "custom",
      "tokenizer": "standard",
      "filter": [
        "lowercase",
        "autocomplete_filter"
      ]
     }
    }
   } 
  }
}

希望能对你有所帮助。
