项目结构：

Entity：

package com.toov5.entity;  import org.springframework.data.annotation.Id; import org.springframework.data.elasticsearch.annotations.Document;  import lombok.Data;     @Document(indexName="toov5",type="user")   //索引的名字  类型  @Data  public class UserEntity {   @Id       private String id;   private String name;   private Integer age;   private Integer sex; }

Dao：

package com.toov5.dao;  import org.springframework.data.repository.CrudRepository;  import com.toov5.entity.UserEntity;  public interface UserDao extends CrudRepository<UserEntity, String> {            }

Controller：

package com.toov5.controller;  import java.util.Optional;  import org.springframework.beans.factory.annotation.Autowired; import org.springframework.web.bind.annotation.RequestBody; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController;  import com.toov5.dao.UserDao; import com.toov5.entity.UserEntity;  @RestController public class EsController {          @Autowired     private UserDao userDao;          //添加文档     @RequestMapping("/addUser")     public UserEntity addUser(@RequestBody UserEntity userEntity) {       return userDao.save(userEntity);         }           //查询文档     @RequestMapping("/findById")     public Optional<UserEntity> findById(String id) {        return userDao.findById(id);         }      }
