软件架构

  1. SpringBoot + REST Client

项目介绍

SpringBoot整合ES的方式(TransportClient、Data-ES、Elasticsearch SQL、REST Client)

  • TransportClient

TransportClient即将弃用,所以这种方式不考虑

  • Data-ES

Spring提供的封装的方式,好像底层也是基于TransportClient,Elasticsearch7.0后的版本不怎么支持,SpringBoot的Spring Boot Data Elasticsearch Starter最高版本2.1.7.RELEASE下载的是Spring Data Elasticsearch的3.1.5版本对应的是Elasticsearch 6.4.3版本,Spring Data Elasticsearch最新版3.1.10对应的还是Elasticsearch 6.4.3版本,我安装的是最新的Elasticsearch 7.2.0版本所以也没办法使用

  • Elasticsearch SQL

将Elasticsearch的Query DSLSQL转换查询,早期有一个第三方的插件Elasticsearch-SQL,后来随着官方也开始做这方面,这个插件好像就没怎么更新了,有兴趣的可以查看:https://www.cnblogs.com/jajian/p/10053504.html

  • REST Client

官方推荐使用,所以我们采用这个方式,这个分为两个Low Level REST Client和High Level REST Client,Low Level REST Client是早期出的API比较简陋了,还需要自己去拼写Query DSL,High Level REST Client使用起来更好用,更符合面向对象的感觉,两个都使用下吧

基础架子搭建

创建一个SpringBoot 2.1.3Maven项目,这块不再详细描述,添加如下REST Client依赖

<elasticsearch.version>7.2.0</elasticsearch.version>

<!-- Java Low Level REST Client -->
<dependency>
    <groupId>org.elasticsearch.client</groupId>
    <artifactId>elasticsearch-rest-client</artifactId>
    <version>${elasticsearch.version}</version>
</dependency>

<!-- Java High Level REST Client -->
<dependency>
    <groupId>org.elasticsearch.client</groupId>
    <artifactId>elasticsearch-rest-high-level-client</artifactId>
    <version>${elasticsearch.version}</version>
</dependency>
  • 配置文件
server:
    port: 8080

spring:
    thymeleaf:
        # 开发时关闭缓存不然没法看到实时页面
        cache: false
        # 启用不严格检查
        mode: LEGACYHTML5

# Elasticsearch配置
elasticsearch:
    hostname: 127.0.0.1
    port: 9500
@Configuration
public class RestClientConfig {

    @Value("${elasticsearch.hostname}")
    private String hostname;

    @Value("${elasticsearch.port}")
    private int port;

    /**
     * LowLevelRestConfig
     *
     * @param
     * @return org.elasticsearch.client.RestClient
     * @author wliduo[i@dolyw.com]
     * @date 2019/8/12 18:56
     */
    @Bean
    public RestClient restClient() {
        // 如果有多个从节点可以持续在内部new多个HttpHost,参数1是IP,参数2是端口,参数3是通信协议
        RestClientBuilder clientBuilder = RestClient.builder(new HttpHost(hostname, port, "http"));
        // 设置Header编码
        Header[] defaultHeaders = {new BasicHeader("content-type", "application/json")};
        clientBuilder.setDefaultHeaders(defaultHeaders);
        // 添加其他配置,这些配置都是可选的,详情配置可看https://blog.csdn.net/jacksonary/article/details/82729556
        return clientBuilder.build();
    }

    /**
     * HighLevelRestConfig
     *
     * @param
     * @return org.elasticsearch.client.RestClient
     * @author wliduo[i@dolyw.com]
     * @date 2019/8/12 18:56
     */
    @Bean
    public RestHighLevelClient restHighLevelClient() {
        // 如果有多个从节点可以持续在内部new多个HttpHost,参数1是IP,参数2是端口,参数3是通信协议
        return new RestHighLevelClient(RestClient.builder(new HttpHost(hostname, port, "http")));
    }

}
这样就配置完成了

LowLevelRestController和HighLevelRestController一对比就能看出来了,HighLevelRestController使用起来更舒服
接口都实现了,实际请查看代码,最后用Vue + ElementUI写了一个前端界面
  • 界面实现网页common.html
