pom文件注意自己的elasticsearch服务端版本下面的方式只在6.8.0版本测试过

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-elasticsearch</artifactId>
        </dependency>
        <dependency>
            <groupId>org.elasticsearch</groupId>
            <artifactId>elasticsearch</artifactId>
            <version>6.8.11</version>
        </dependency>
        <dependency>
            <groupId>org.elasticsearch.client</groupId>
            <artifactId>x-pack-transport</artifactId>
            <version>6.8.11</version>
        </dependency>

配置类

@Configuration
public class ElasticsearchConfig {
	//连接信息改成自己的
	private String clusterName = "elasticsearch";

	private String clusterNodes = "127.0.0.1";
	//用户名：密码
	private String clusterPassword = "elastic:123456";

	@Bean
	public Client client() throws Exception {
		@SuppressWarnings("resource")
		Client client = new PreBuiltXPackTransportClient(Settings.builder()
	            .put("cluster.name", clusterName)
	            .put("xpack.security.user", clusterPassword)
	            .build())
	            .addTransportAddress(new TransportAddress(InetAddress.getByName(clusterNodes), 9300));
	    return client;
	    }

	@Bean(name = "elasticsearchTemplate")
	public ElasticsearchTemplate elasticsearchTemplate() throws Exception {
		ElasticsearchTemplate elasticsearchTemplate;
		try {
			elasticsearchTemplate = new ElasticsearchTemplate(client());
			return elasticsearchTemplate;
		} catch (Exception e) {
			e.printStackTrace();
			return new ElasticsearchTemplate(client());
		}
	}

}
