  • 索引entity如下：
@Data
@Accessors(chain = true)
@Settings(shardsNum = 3, replicasNum = 0)
@IndexName(value = "test", keepGlobalPrefix = true)
public class TestIndex {

    @IndexId(type = IdType.CUSTOMIZE)
    private String id;

    // 作者简称
    private List<String> au;
    
    @HighLight(mappingField = "highlight")
    @IndexField(fieldType = FieldType.NESTED, analyzer = Analyzer.IK_MAX_WORD)
    private List<AuthorInfoVo> au_info;
}
  • 使用的easy-es配置如下：
easy-es:
  enable: true
  address: localhost:9200
  #  schema: https
  #  username: elastic
  #  password: WG7WVmuNMtM4GwNYkyWH
  keep-alive-millis: 18000

    print-dsl: true
    db-config:
      map-underscore-to-camel-case: true
      id-type: customize
      field-strategy: IGNORED
      refresh-policy: immediate
      enable-track-total-hits: true

  • 虽然也能用，但是看到报错有点不爽
  • 我不确定是不是nested类型的需要额外配置，文档中没有nested类型相关的
  • 希望各位大佬，有空看一下

懂了，有个nestedClass属性
