如何用spring boot 2.15正确配置elasticsearch 7.1.1？

Question

我使用的是Elasticsearch 7.1.1和spring-boot 2.1.5。我下载了Elasticsearch并运行它。当我启动spring项目时，我得到了一个错误。“未能加载Elasticsearch节点:org.Elasticsearch.client.transport.nonodeAvailableException:配置的节点均不可用:[{#Transport#-1}{rsi4dYt_RuOBGCdwUH3Cgg}{127.0.0.1}{127.0.0.1:9200}]”。我怎样才能正确地

我用了这些配置。

spring.elasticsearch.jest.multi-threaded=true
spring.main.allow-bean-definition-overriding=true
spring.data.elasticsearch.cluster-nodes=localhost:9200
spring.data.elasticsearch.repositories.enabled=true
spring.elasticsearch.jest.uris=http://localhost:9200
spring.elasticsearch.jest.connection-timeout=3s
spring.elasticsearch.rest.uris=http://localhost:9200
spring.data.elasticsearch.cluster-name=elasticsearch

和

@Configuration
@EnableElasticsearchRepositories(basePackages = 
"com.example.elasticsearch.repository")
public class ElasticSearchConfiguration {
 @Bean
 public Client client() throws UnknownHostException {
    Settings settings = Settings.builder()
            .put("client.transport.sniff", true)
            .put("cluster.name", "elasticsearch").build();
    @SuppressWarnings("resource")
    TransportClient client = new PreBuiltTransportClient(settings)
            .addTransportAddress(new 
 TransportAddress(InetAddress.getByName("127.0.0.1"), 9200));

    return client;
}

@Bean
public ElasticsearchOperations elasticsearchTemplate() throws 
UnknownHostException {
    return new ElasticsearchTemplate(client());
   }
}

我想如果您的理解是错误的，请使用port=9200，请尝试使用port=9300。从应用程序连接到弹性搜索服务器时，将使用端口号9300，而不是9200。
