@DS(“source”) aop原理
同层调用会失败 事务 ds asyc!!!

SpringBoot2.2.x版本才支持ElasticSearch7.x，需要先升级SpringBoot版本
6.0ElasticsearchTemplate 替换为 7.0ElasticsearchRestTemplate（TransportClient 替换为 RestHighLevelClient ） 很多方法不一样!!! config配置yml配置
SpringBoot2.2.x版本才支持ElasticSearch7.x es7的java代码，只能使用restclient,TransportClient被废弃
是由于6.0的版本不允许一个index下面有多个type，并且官方说是在接下来的7.0版本中会删掉type

org.springframework.data spring-data-elasticsearch x.y.z.RELEASE org.elasticsearch.client transport x.y.z

es的版本

org.elasticsearch elasticsearch 6.2.3

这里使用了ElasticsearchRestTemplate这个类，对应于RestHighLevelClient

public class EsConfiguration extends AbstractElasticsearchConfiguration {
@Override
@Bean
public RestHighLevelClient elasticsearchClient() {
final ClientConfiguration clientConfiguration = ClientConfiguration.builder()
.connectedTo(“localhost:9200”)
.build();

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

@Bean
public ElasticsearchRestTemplate elasticsearchRestTemplate(){
    return new ElasticsearchRestTemplate(elasticsearchClient());
}

@Configuration
public class TransportClientConfig extends ElasticsearchConfigurationSupport {

@Bean
public Client elasticsearchClient() throws UnknownHostException {
	Settings settings = Settings.builder().put("cluster.name", "elasticsearch").build();
	TransportClient client = new PreBuiltTransportClient(settings);
            // 注意端口为 9300
	client.addTransportAddress(new TransportAddress(InetAddress.getByName("127.0.0.1"), 9300));
	return client;
}

@Bean(name = {"elasticsearchOperations", "elasticsearchTemplate"})
public ElasticsearchTemplate elasticsearchTemplate() throws UnknownHostException {
	return new ElasticsearchTemplate(elasticsearchClient(), entityMapper());
}

}

@Bean
public TransportClient transportClient() throws UnknownHostException {
TransportClient client = new PreBuiltXPackTransportClient(Settings.builder()
.put(“cluster.name”, “es-cluster”)
.put(“xpack.security.user”, “elastic:changeme”)
.build())
.addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName(“127.0.0.1”), 9300));
return client;
}
