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);
