spingboot父依赖版本：

<parent>    
	<groupId>org.springframework.boot</groupId>    
	<artifactId>spring-boot-starter-parent</artifactId>
	<version>2.3.4.RELEASE</version>
</parent>

添加实体类映射：

package com.aipf.apply.esparam;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import org.springframework.data.elasticsearch.annotations.DateFormat;
import org.springframework.data.elasticsearch.annotations.Document;
import org.springframework.data.elasticsearch.annotations.Field;
import org.springframework.data.elasticsearch.annotations.FieldType;
import org.springframework.stereotype.Component;
import java.util.Date;

@Data@AllArgsConstructor
@NoArgsConstructor
@Document(indexName = "two_tickets_ai_info")
@Component
public class CameraNotice {
         
private Long id;    
@Field(name = "@timestamp",type = FieldType.Date,format = DateFormat.custom,pattern = "yyyy-MM-dd'T'HH:mm:ss.SSS'Z'")    
protected Date timestamp;  
@Field(name = "in_cnt")    
private int inCount;  
@Field(name = "out_cnt")    
private int outCount;
@Field(name = "no_judge_cnt")    
private int noJudgeCount;     
@Field(name = "camera_id")    
private Integer cameraId;

添加dao层操作对象

package com.aipf.apply.dao;

import com.aipf.apply.esparam.CameraNotice;
import org.springframework.data.elasticsearch.repository.ElasticsearchCrudRepository;

public interface CameraNoticeDao extends ElasticsearchCrudRepository<CameraNotice,Long> {
     }

操作es

@Autowired
private CameraNoticeDao cameraNoticeDao;

CameraNotice cameraNotice = new CameraNotice();
cameraNoticeDao.save(cameraNotice); //向es存入数据
