springboot整合es客户端操作elasticsearch（三）

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;

import org.elasticsearch.action.delete.DeleteRequest;

import org.elasticsearch.action.delete.DeleteResponse;

import org.elasticsearch.action.get.GetRequest;

import org.elasticsearch.action.get.GetResponse;

import org.elasticsearch.action.update.UpdateRequest;

import org.elasticsearch.action.update.UpdateResponse;

import org.elasticsearch.client.RequestOptions;

import org.elasticsearch.client.RestClient;

import org.elasticsearch.client.RestHighLevelClient;

import org.elasticsearch.rest.RestStatus;

import org.elasticsearch.snapshots.SnapshotShardsService;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.RequestMethod;

import org.springframework.web.bind.annotation.RestController;

import javax.xml.transform.Source;

import java.io.IOException;

import java.util.HashMap;

import java.util.Map;

@RestController

public class EsindexController {

    @Autowired

    RestHighLevelClient client;

    @Autowired

    RestClient restClient;

    @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" ;

    }

}

调用接口：

localhost:8085/updatedoc

成功：

调用删除接口，删除得是数据第一条：

接口：

可以看到已经删除了。所以对文档得增加，删除，修改，查询已经完成了，下个随便将会写对文档得精确，模糊，分数查询
