SpringBoot 调用设置密码的 Elasticsearch-Toy模板网

这篇具有很好参考价值的文章主要介绍了SpringBoot 调用设置密码的 Elasticsearch。希望对大家有所帮助。如果存在错误或未考虑完全的地方，请大家不吝赐教，您也可以点击"举报违法"按钮提交疑问。

最近项目中使用到的Elasticsearch是设置密码的，所以我们在Springboot中使用的过程中也需要指定密码才可以连接到Elasticsearch，特此记录便于日后查阅。

增加 bootstrap.yaml 配置：

elasticsearch:
  schema: http
  address: 127.0.0.1:9200
  connectTimeout: 5000
  socketTimeout: 5000
  connectionRequestTimeout: 5000
  maxConnectNum: 100
  maxConnectPerRoute: 100
  UserName: elastic
  Password: 123456

修改ElasticSearchConfiguration类

package com.zcdsj.ElasticSearch;
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.RestClient;
import org.elasticsearch.client.RestClientBuilder;
import org.elasticsearch.client.RestHighLevelClient;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import java.util.ArrayList;
import java.util.List;
/** * @Deacription ElasticSearch 配置 * @Author x **/
@Configuration
public class ElasticSearchConfiguration { 
    /** 协议 */
    @Value("${elasticsearch.schema:http}")
    private String schema;
    /** 集群地址，如果有多个用“,”隔开 */
    @Value("${elasticsearch.address}")
    private String address;
    /** 连接超时时间 */
    @Value("${elasticsearch.connectTimeout}")
    private int connectTimeout;
    /** Socket 连接超时时间 */
    @Value("${elasticsearch.socketTimeout}")
    private int socketTimeout;
    /** 获取连接的超时时间 */
    @Value("${elasticsearch.connectionRequestTimeout}")
    private int connectionRequestTimeout;
    /** 最大连接数 */
    @Value("${elasticsearch.maxConnectNum}")
    private int maxConnectNum;
    /** 最大路由连接数 */
    @Value("${elasticsearch.maxConnectPerRoute}")
    private int maxConnectPerRoute;
    @Value("${elasticsearch.UserName}")
    private String userName;
    @Value("${elasticsearch.Password}")
    private String password;
    @Bean(name = "restHighLevelClient")
    public RestHighLevelClient restHighLevelClient() { 
        // 拆分地址
        List<HttpHost> hostLists = new ArrayList<>();
        String[] hostList = address.split(",");
        for (String addr : hostList) { 
            String host = addr.split(":")[0];
            String port = addr.split(":")[1];
            hostLists.add(new HttpHost(host, Integer.parseInt(port), schema));
        }
        final CredentialsProvider credentialsProvider = new BasicCredentialsProvider();
        credentialsProvider.setCredentials(AuthScope.ANY, new UsernamePasswordCredentials(userName, password));
        // 转换成 HttpHost 数组
        HttpHost[] httpHost = hostLists.toArray(new HttpHost[]{ });
        // 构建连接对象
        RestClientBuilder builder = RestClient.builder(httpHost);
        // 异步连接延时配置
        builder.setRequestConfigCallback(requestConfigBuilder -> { 
            requestConfigBuilder.setConnectTimeout(connectTimeout);
            requestConfigBuilder.setSocketTimeout(socketTimeout);
            requestConfigBuilder.setConnectionRequestTimeout(connectionRequestTimeout);
            return requestConfigBuilder;
        });
        // 异步连接数配置
        builder.setHttpClientConfigCallback(httpClientBuilder -> { 
            httpClientBuilder.setMaxConnTotal(maxConnectNum);
            httpClientBuilder.setMaxConnPerRoute(maxConnectPerRoute);
            return httpClientBuilder.setDefaultCredentialsProvider(credentialsProvider);
        });
        return new RestHighLevelClient(builder);
    }
}

打开 http://127.0.0.1:8082/all/addDocument 密码访问就完成了。文章来源地址https://www.toymoban.com/news/detail-663002.html
