Elasticsearch 整合springboot-Elasticsearch文章二

官网

https://www.elastic.co/cn/

版本

https://docs.spring.io/spring-data/elasticsearch/docs/4.4.10/reference/html/

我们选用的是elasticsearch 7.17.9版本，对应的，我们需要升级springboot版本，对应的中间件都需要升级

组件版本说明

Springboot: 2.7.10
spring-data-elasticsearch: 4.4.10
spring-boot-starter-data-elasticsearch: 2.7.10

application.yml

spring:
  # Jackson 配置项
  jackson:
    #    serialization:
    #      write-dates-as-timestamps: true # 设置 Date 的格式，使用时间戳
    #      write-date-timestamps-as-nanoseconds: false # 设置不使用 nanoseconds 的格式。例如说 1611460870.401，而是直接 1611460870401
    #      write-durations-as-timestamps: true # 设置 Duration 的格式，使用时间戳
    #      fail-on-empty-beans: false # 允许序列化无属性的 Bean

Repository

package org.lwd.microservice.boot.es.dao;

import org.lwd.microservice.boot.es.entity.VisitLog;
import org.springframework.data.elasticsearch.repository.ElasticsearchRepository;
import org.springframework.stereotype.Repository;

import java.util.List;

/**
 * @author weidong
 * @version V1.0.0
 * @since 2023/7/26
 */
@Repository
public interface VisitLogRepository extends ElasticsearchRepository<VisitLog, String> {

    //自定义规则
    List<VisitLog> findByUserLoginId(Integer userLoginId);
}

VisitLog模型定义

package org.lwd.microservice.boot.es.entity;

import lombok.Getter;
import lombok.Setter;
import org.springframework.data.annotation.Id;
import org.springframework.data.elasticsearch.annotations.Document;

import java.io.Serializable;
import java.util.Date;

/**
 * 

 * 系统访问日志
 * 
 *
 * @author lwd
 * @since 2023-07-26
 */
@Getter
@Setter
@Document(indexName = "visit_log")
public class VisitLog implements Serializable {

    private static final long serialVersionUID = 1L;

    /**
     *访问id
     */
    @Id
    private Integer id;

    /**
     * 不同业务表明
     */
    private String tableName;
    /**
     *登录账号
     */
    private String userLoginId;

    /**
     *服务ip
     */
    private String serverIpAddress;

    /**
     *服务名
     */
    private String serverHostName;

    /**
     *请求url
     */
    private String initialRequest;

    /**
     *消息内容
     */
    private String msgContent;

    /**
     *创建时间
     */
    private Date createTime;

}

controller使用

中间服务层定义掠过了。。。。

package org.lwd.microservice.boot.es.controller;

import com.alibaba.fastjson2.JSON;
import lombok.extern.slf4j.Slf4j;
import org.elasticsearch.client.RestHighLevelClient;
import org.lwd.microservice.boot.es.entity.VisitLog;
import org.lwd.microservice.boot.es.service.VisitLogService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.domain.PageRequest;
import org.springframework.data.elasticsearch.core.*;
import org.springframework.data.elasticsearch.core.query.Query;
import org.springframework.data.elasticsearch.core.query.StringQuery;
import org.springframework.web.bind.annotation.*;
import reactor.core.publisher.Flux;
import reactor.core.publisher.Mono;

import java.util.List;

/**
 * @author weidong
 * @version V1.0.0
 * @since 2023/7/26
 */
@Slf4j
@RestController
@RequestMapping("/es")
public class VisitLogController {
    @Autowired
    VisitLogService visitLogService;

    //rest模版操作
    @Autowired
    ElasticsearchOperations elasticsearchOperations;

    //响应式模版操作
    @Autowired
    ReactiveElasticsearchOperations reactiveElasticsearchOperations;


    @PostMapping("/saveVisitLog")
    @ResponseBody
    public String saveVisitLog(@RequestBody VisitLog visitLog){
        VisitLog saveVisitLog = visitLogService.saveVisitLog(visitLog);
        log.info("----saveVisitLog----:{}", JSON.toJSONString(saveVisitLog));
        return JSON.toJSONString(saveVisitLog);
    }

    @GetMapping("/getVisitLogAll")
    @ResponseBody
    public String getVisitLogAll(){
        List<VisitLog> logList = visitLogService.findAll();
        log.info("----getVisitLogAll----:{}", JSON.toJSONString(logList));
        return JSON.toJSONString(logList);
    }

    //自定义查询
    @GetMapping("/getVisitLogByUserLoginId")
    @ResponseBody
    public String getVisitLogByUserLoginId(Integer userLoginId){
        List<VisitLog> logList = visitLogService.findByUserLoginId(userLoginId);
        log.info("----getVisitLogAll----:{}", JSON.toJSONString(logList));
        return JSON.toJSONString(logList);
    }
}

测试http请求

TestEs.http

## 新增日志
POST http://localhost:8023/es/saveVisitLog
Content-Type: application/json

{
  "id": 3,
  "tableName": "VisitLog",
  "userLoginId": 3,
  "serverIpAddress": "127.0.0.1",
  "serverHostName": "weidong",
  "initialRequest": "http://localhost:8023",
  "msgContent": "test es add3",
  "createTime": "2023-07-27 16:34:36"
}


### 获取所有数据-不分页

GET http://localhost:8023/es/getVisitLogAll

### 获取所有数据-自定义查询规则

GET http://localhost:8023/es/getVisitLogByUserLoginId?userLoginId=1

结果

kibana结果

@ID

如果不赋值给ID，那么es会自动生成一个字符串，但是，获取数据可能出问题
