Spring boot 接入ES

最终效果：

最终效果
效果丑，也就那么意思一下；因为sping boot已经集成了es，所以接入es只需要很简单的配置一下就好了。当然事先得下载好es，我用的是windows 6.5.3版本，没有遇到什么版本冲突问题，至于安装es和建立spring boot项目我就不细说了。

代码：

引入需要的jar包就好

application.yml

spring:
  datasource:
    hikari:
      jdbc-url: jdbc:mysql://url:port/database
      username: username
      password: password
      driver-class-name: com.mysql.jdbc.Driver
    url: jdbc:mysql://url:port/database
    username: username
    password: password
    driver-class-name: com.mysql.cj.jdbc.Driver
  thymeleaf:
    cache: false
    prefix: classpath:templates/
    suffix: .html
    mode: HTML
    encoding: UTF-8
  data:
    elasticsearch:
      cluster-name: es-test
      cluster-nodes: localhost:9300
      repositories:
        enabled: true
  main:
    allow-bean-definition-overriding: true
server:
  port: 80
mybatis:
  type-aliases-package: com.xxx.xxx.xxx

cluster-name就是自己设置的es集群名称，可以在es安装目录下面的config/elasticsearch.yml配置

实体类

package com.xxx.xxx.model;

import org.springframework.data.annotation.Id;
import org.springframework.data.elasticsearch.annotations.Document;
import org.springframework.data.elasticsearch.annotations.Field;
import org.springframework.data.elasticsearch.annotations.FieldType;

import java.util.Date;

@Document(indexName = "test", type = "company")
public class Company {
    @Id
    private String id;

    @Field(analyzer = "ik",searchAnalyzer = "ik",store = true,type = FieldType.Text)
    private String cname;

    private String ename;

    private String iname;

    private String scode;

    private String amt;

    private String person;

    @Field
    private Date btime;

    @Field
    private Date sbtime;

    @Field
    private Date ptime;

    private String address;

    private String tel;

    private String fax;

    private String web;

    private String email;

    private String sec;

    @Field(analyzer = "ik",searchAnalyzer = "ik",store = true,type = FieldType.Text)
    private String industry;

    private String business;

    private String recommend;

    private String over
