我试图使用注释更改实体中字段的名称
@JsonNaming(PropertyNamingStrategy.UpperCamelCaseStrategy.class)
和
@JsonProperty()
对于嵌套字段，但这不适用于嵌套字段，例如：
实体集：
@JsonNaming(PropertyNamingStrategy.UpperCamelCaseStrategy.class)
public class TaxMapKey {
private String parcelNumber;
private String ownershipType;
@JsonProperty("TransferList")
@Field(type = FieldType.Nested, includeInParent = true)
private Set<Transfer> transferList = new HashSet<>();
}
@JsonNaming(PropertyNamingStrategy.UpperCamelCaseStrategy.class)
public class Transfer {
private Long transferId;
private String documentNumber;
@JsonProperty("Grantor")
@Field(type = FieldType.Nested)
private Grantor grantor;
}
@JsonNaming(PropertyNamingStrategy.UpperCamelCaseStrategy.class)
public class Grantor {
private Long grantorId;
private String documentNumber;
private Integer price;
private String instrumentType;
}
当我使用这样的查询从该实体请求数据时：
curl -X GET \
http://localhost:9200/search_tax_map_key/_search \
-H 'Content-Type: application/json' \
-d '{
"_source": ["TransferList.Grantor.Price", "TransferList.Grantor.InstrumentType"]
}
我得到了这样的答复（如您所见，字段是UpperCamelCase）：
{
"took": 86,
"timed_out": false,
"_shards": {
"total": 5,
"successful": 5,
"skipped": 0,
"failed": 0
},
"hits": {
"total": 1,
"max_score": 1,
"hits": [
{
"_index": "search_tax_map_key",
"_type": "taxMapKey",
"_id": "fbWo3GgB23V4WRXcMn-8",
"_score": 1,
"_source": {
"TransferList": [
{
"Grantor": {
"Price": 220000,
"InstrumentType": "DEED "
}
},
{
"Grantor": {
"Price": 170000,
"InstrumentType": "DEED "
}
},
{
"Grantor": {
"Price": 0,
"InstrumentType": "TRANSD "
}
},
{
"Grantor": {
"Price": 44000,
"InstrumentType": "DEED "
}
},
{
"Grantor": {
"Price": 0,
"InstrumentType": "DEED "
}
}
]
}
}
]
}
}
但是在元数据信息中，我有这样的结构：
curl -X GET \
http://localhost:9200/search_tax_map_key \
-H 'Content-Type: application/json' \
{
"search_tax_map_key": {

}
},
"InstrumentType": {
"type": "text",
"fields": {

}
},

"type": "nested",
"include_in_parent": true,

}
}
如您所见，我有两个对象，例如transferList（命名未转换为大驼峰案例）和另一个TransferList（已转换为大驼峰案例）
由于类似错误，我无法使用大写驼峰命名字段进行请求

如何将@JsonNaming（PropertyNamingStrategy.UpperCamelCaseStrategy.class）用于嵌套字段？
