Hibernate 搜索和 elasticsearch:mapper_parsing_exception + analyzer [...] 未找到字段 [...]
Hibernate search and elasticsearch: mapper_parsing_exception + analyzer [...] not found for field [...]
我正在使用休眠搜索自动为特定实体创建索引
@Entity
@Indexed
public class Entity extends BaseEntity {
private static final long serialVersionUID = -6465422564073923433L;
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
@OneToMany(fetch = FetchType.LAZY, cascade = CascadeType.ALL, orphanRemoval = true)
@Field(bridge = @FieldBridge(impl = PropertyFieldBridge.class))
private List<PropertyValue> properties = new ArrayList<>(); // PropertyValue is an abstract
}
字段桥正在创建字符串字段,格式为:pt_[a-zA-Z0-9]+_i18n。
然后我创建了一个动态模板来处理翻译后的字段:
PUT {{elasticsearch}}/com.orm.entity.entity.entity/com.orm.entity.entity.Entity/_mapping
{
"com.gamila.api.orm.entity.entity.Entity": {
"dynamic_templates": [
{
"my_analyzer": {
"match_mapping_type": "string",
"match_pattern": "regex",
"match": "^pt_[a-zA-Z0-9]+_i18n",
"mapping": {
"type": "text",
"analyzer": "portugueseAnalyzer"
}
}
}
]
}
}
但是当我创建一个实体时它总是returns一个错误:
Response: 400 'Bad Request' with body
{
"error": {
"root_cause": [
{
"type": "mapper_parsing_exception",
"reason": "analyzer [portugueseAnalyzer] not found for field [pt_name_i18n]"
}
],
"type": "mapper_parsing_exception",
"reason": "analyzer [portugueseAnalyzer] not found for field [pt_name_i18n]"
},
"status": 400
}
PortugueseAnalyser 是通过以下方式定义的:
public class Analyzer implements ElasticsearchAnalysisDefinitionProvider {
@Override
public void register(ElasticsearchAnalysisDefinitionRegistryBuilder builder) {
builder.analyzer("portugueseAnalyzer")
.withTokenizer("standard")
.withTokenFilters("lowercase", "portugueseStemmer", "portugueseStop", "edge_ngram_3");
builder.tokenFilter("portugueseStemmer")
.type("stemmer").param("language", "portuguese");
builder.tokenFilter("portugueseStop")
.type("stop").param("stopwords", "_portuguese_");
}
}
有人可以告诉我我做错了什么吗?我已经在 Whosebug 中浏览了一些问题,但没有成功。
PS:我正在使用来自 AWS
的弹性搜索 (5.6)

当 Hibernate Search 5 将映射推送到 Elasticsearch 时,它只会包含映射中某处实际使用的分析器的分析器定义。在你的例子中,就 Hibernate Search 而言,分析器没有被使用,所以它被忽略了。
作为 Hibernate Search 5 中的解决方法,您可以声明一个使用分析器但永远不会填充的虚拟字段。您可以找到如何执行此操作的示例 here.
