spring集成elasticSearch es spring-boot-starter-data-elasticsearch 权限 密码配置

本文讲述使用spring集成elasticSearch

  org.springframework.boot
  spring-boot-starter-data-elasticsearch

不同的版本的配置方法不太一致。这里我呈现两个版本的配置方式

方法一、yml文件添加

spring:
  elasticsearch:
    uris: ["127.0.0.1:9200"]
    username: "elastic"
    password: "yuyuyu"
    

方法二、便携config文件

package com.example.esdemo;

import lombok.extern.log4j.Log4j2;
import org.apache.http.HttpHost;
import org.apache.http.auth.AuthScope;
import org.apache.http.auth.UsernamePasswordCredentials;
import org.apache.http.client.CredentialsProvider;
import org.apache.http.impl.client.BasicCredentialsProvider;
import org.elasticsearch.client.RequestOptions;
import org.elasticsearch.client.RestClient;
import org.elasticsearch.client.RestClientBuilder;
import org.elasticsearch.client.RestHighLevelClient;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.elasticsearch.client.ClientConfiguration;
import org.springframework.data.elasticsearch.client.RestClients;
import org.springframework.data.elasticsearch.client.reactive.ReactiveElasticsearchClient;
import org.springframework.data.elasticsearch.client.reactive.ReactiveRestClients;
import org.springframework.data.elasticsearch.config.AbstractElasticsearchConfiguration;
import org.springframework.data.elasticsearch.config.AbstractReactiveElasticsearchConfiguration;
import org.springframework.http.HttpHeaders;

import java.time.Duration;
import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;

@Configuration
public class ReactiveRestClientConfig extends AbstractElasticsearchConfiguration {
    private String host = "127.0.0.1";
    private Integer port = 9200;
    private String userName = "elastic";
    private String password = "yuyuyu";

    @Override
    public RestHighLevelClient elasticsearchClient() {
        final ClientConfiguration clientConfiguration = ClientConfiguration.builder()
                .connectedTo("localhost:9200")
                .withBasicAuth(userName,password)
                .build();

        return RestClients.create(clientConfiguration).rest();
    }
}

如果是带密码的最好再yml配置下忽略将康检测。否则启动会报错（无伤大雅，非强迫症可以不理）。

// 去除es数据库健康检查
management:
  health:
    elasticsearch:
      enabled: false

方法一、配置yml文件

  elasticsearch:
    rest:
      uris: [ "127.0.0.1:9200" ]
      username: "elastic"
      password: "yuyuyu"

        import lombok.extern.log4j.Log4j2;
        import org.apache.http.HttpHost;
        import org.apache.http.auth.AuthScope;
        import org.apache.http.auth.UsernamePasswordCredentials;
        import org.apache.http.client.CredentialsProvider;
        import org.apache.http.impl.client.BasicCredentialsProvider;
        import org.elasticsearch.client.RequestOptions;
        import org.elasticsearch.client.RestClient;
        import org.elasticsearch.client.RestClientBuilder;
        import org.elasticsearch.client.RestHighLevelClient;
        import org.springframework.context.annotation.Bean;
        import org.springframework.context.annotation.Configuration;
        import org.springframework.data.elasticsearch.client.ClientConfiguration;

        import org.springframework.data.elasticsearch.config.AbstractElasticsearchConfiguration;
        import org.springframework.data.elasticsearch.config.AbstractReactiveElasticsearchConfiguration;
        import org.springframework.http.HttpHeaders;

        import java.time.Duration;
        import java.time.LocalDateTime;
        import java.time.format.DateTimeFormatter;

@Configuration

    private String host = "127.0.0.1";
    private Integer port = 9200;
    private String userName = "elastic";
    private String password = "yuyuyu";

    @Override
    public RestHighLevelClient elasticsearchClient() {
        final ClientConfiguration clientConfiguration = ClientConfiguration.builder()
                .connectedTo("localhost:9200")
                .withBasicAuth(userName,password)
                .build();

        return RestClients.create(clientConfiguration).rest();
    }
}

之后有其他版本都根据下图自己摸索配置方法
