篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了springboot整合es客户端操作elasticsearch相关的知识，希望对你有一定的参考价值。

继续上个随笔：

那么我们只需要修改controller中文件就可以完成相关操作

本次主要是对文档得操作：

更新文档：

package com.cxy.elasticsearch.controller;

@RestController
public class EsindexController {
    @Autowired
    RestHighLevelClient client;

    @Autowired

    @RequestMapping(value = "/updatedoc",method = RequestMethod.GET)
    public String updatedoc(){
        UpdateRequest updateRequest = new UpdateRequest("chenxuyou3","doc","ekBpCG8BAmmLmqjtgRwU");
        HashMap<String, String> stringStringHashMap = new HashMap<>();
        stringStringHashMap.put("name","Ealsticseach学习实战");
        updateRequest.doc(stringStringHashMap);
        UpdateResponse update =null;
        try {
            update= client.update(updateRequest, RequestOptions.DEFAULT);
        } catch (IOException e) {
            e.printStackTrace();
        }
        RestStatus status = update.status();
        System.err.println(status);

        return "ok" ;
    }
    @RequestMapping(value = "/deletedoc",method = RequestMethod.GET)
    public String deletedoc(){
       String id ="e0CECG8BAmmLmqjt6hwW";
       DeleteRequest deleteRequest = new DeleteRequest("chenxuyou3", "doc", id);
        DeleteResponse delete = null;
        try {
            delete = client.delete(deleteRequest, RequestOptions.DEFAULT);
        } catch (IOException e) {
            e.printStackTrace();
        }
        RestStatus status = delete.status();
        System.err.println(status);

        return "ok" ;
    }

}
