1.在spring原有及基础上新增Maven依赖


        <dependency>
            <groupId>org.elasticsearch.client</groupId>
            <artifactId>elasticsearch-rest-client</artifactId>
            <version>6.3.2</version>
        </dependency>

        <dependency>
            <groupId>org.elasticsearch.client</groupId>
            <artifactId>elasticsearch-rest-high-level-client</artifactId>
            <version>6.3.2</version>
        </dependency>

2.ES 配置参数

创建 ElasticSearchProperties类

@ConfigurationProperties(prefix = "com.commons.es")
public class ElasticSearchProperties {
    private String host = "localhost";
    private int port = 9200;
    private String schema = "http";
    private int connectTimeOut = 1000;
    private int socketTimeOut = 30000;
    private int connectionRequestTimeOut = 500;
    private int maxConnectNum = 100;
    private int maxConnectPerRoute = 100;
    private boolean uniqueConnectTimeConfig = true;
    private boolean uniqueConnectNumConfig = true;
    private Integer shades = 3;//分片数
    private Integer replicas = 2;//副本数
}

3.ES Java客户端连接

创建ElasticSearchAutoConfig类

@Configuration
//可根据自己所在的目录要扫描的参数，如下图
@ComponentScan(basePackages = "com.manager.commons.es") 
@EnableConfigurationProperties(ElasticSearchProperties.class)
public class ElasticSearchAutoConfig {
    private HttpHost httpHost;
    private RestClientBuilder builder;
    private RestHighLevelClient client;

    @Autowired
    private ElasticSearchProperties elasticSearchProperties;

    @Bean
    public RestHighLevelClient restHighLevelClient() {
        httpHost = new HttpHost(elasticSearchProperties.getHost(
