我在 Spring Boot 应用程序中使用 Elasticsearch。我正在尝试将“kibana_sample_data_ecommerce”示例索引（Kibana 中的示例数据库之一）转换为 Spring Boot Elasticsearch 实体。
我的实体类：
@Data
@AllArgsConstructor
@NoArgsConstructor
@Builder
@Document(indexName = "kibana_sample_data_ecommerce")
public class Order {
@Id
@Field(type = FieldType.Keyword)
private String id;
@Field(type = FieldType.Text)
private List<String> category;
@Field(type = FieldType.Keyword)
private String currency;
@Field(type = FieldType.Keyword, name = "customer_id")
private String customerId;
@Field(type = FieldType.Text, name = "customer_first_name")
private String customerFirstName;
@Field(type = FieldType.Text, name = "customer_last_name")
private String customerLastName;
@Field(type = FieldType.Text, name = "customer_full_name")
private String customerFullName;
@Field(type = FieldType.Keyword, name = "customer_gender")
private String customerGender;
@Field(type = FieldType.Keyword, name = "customer_phone")
private String customerPhone;
@Field(type = FieldType.Keyword, name = "email")
private String customerEmail;
@Field(type = FieldType.Keyword, name = "day_of_week")
private String dayOfWeek;
@Field(type = FieldType.Integer, name = "day_of_week_i")
private Integer dayOfWeekI;
@Field(type = FieldType.Text, name = "manufacturer")
private List<String> manufacturer;
@Field(type = FieldType.Date, name = "order_date")
private LocalDateTime orderDate;
}

当我尝试获取所有数据时
org.springframework.data.elasticsearch.core.convert.ConversionException: Unable to convert value '2023-10-02T09:28:48+00:00' to java.time.LocalDateTime for property 'orderDate'
我收到错误。
版本：
我该如何解决这个问题？
来自
LocalDateTime此类不存储或表示时区。相反，它是对日期的描述，如生日，与挂钟上显示的当地时间相结合。如果没有偏移量或时区等附加信息，它无法表示时间线上的瞬间。
您尝试解析时间瞬间，该类不支持该瞬间，因为它不携带时区，因此无法确定本地时间是什么。考虑：
import java.time.LocalDateTime;
public class Test {
public static void main(String[] args) {
String d1 = "2023-09-23T18:11:12";
LocalDateTime ldt1 = LocalDateTime.parse(d1);
System.out.println(ldt1);
String d2 = "2023-09-23T18:11:12+00:00";
LocalDateTime ldt2 = LocalDateTime.parse(d2);
System.out.println(ldt2);
}
}
