如何将 Spring 引导与 Elasticsearch 7.3 连接

Question

我正在使用Elasticsearch 7.3，但无法将其连接到我的Spring启动应用程序以使用ElasticsearchRepository。

@Configuration
public class ElasticSearchConfig {
@Value("${elasticsearch.host:localhost}")
public String host;
@Value("${elasticsearch.port:9300}")
public int port;
public String getHost() {
return host;
}
public int getPort() {
return port;
}
private int timeout = 60;
@Bean
public RestHighLevelClient client() {
System.out.println("host:" + host + "port:" + port);
final CredentialsProvider credentialsProvider = new BasicCredentialsProvider();
credentialsProvider.setCredentials(AuthScope.ANY, new UsernamePasswordCredentials("elastic", "changeme"));
RestClientBuilder builder = RestClient.builder(new HttpHost("localhost", 9200, "http")).setHttpClientConfigCallback(httpClientBuilder -> httpClientBuilder.setDefaultCredentialsProvider(credentialsProvider));
builder.setRequestConfigCallback(requestConfigBuilder -> requestConfigBuilder.setConnectTimeout(timeout * 1000).setSocketTimeout(timeout * 1000)
.setConnectionRequestTimeout(0));
RestHighLevelClient client = new RestHighLevelClient(builder);
return client;
}

}

这些是我拥有的依赖项

编译组： 'org.elasticsearch.client'， 名称： 'transport'， 版本： '7.7.1'

编译组： 'org.elasticsearch.client'， 名称： 'Elasticsearch-rest-high-level-client'， 版本： '7.7.1'

编译组："org.springframework.data"，名称："spring-data-elasticsearch"，版本："4.0.1.RELEASE">

但它没有运行。

Answer 1

您使用的是 Spring Boot，无需编写自己的Configuration类 - 您可以使用自动配置的优点。

https://docs.spring.io/spring-boot/docs/1.3.8.RELEASE/reference/html/using-boot-auto-configuration.html

它也适用于弹性搜索，请参阅 https://docs.spring.io/spring-boot/docs/current/api/org/springframework/boot/autoconfigure/data/elasticsearch/ElasticsearchDataAutoConfiguration.html

只需将此行添加到您的应用程序属性中

spring.elasticsearch.rest.uris=http://localhost:9300
spring.elasticsearch.rest.username=elastic
spring.elasticsearch.rest.password=changeme

除此之外，我相信您的依赖项中有一些混乱，请尝试删除它并使用这个

编译组 'org.springframework.boot：spring-boot-starter-data-elasticsearch：2.3.0.RELEASE'

Answer 2

下面是与Elaticsearch依赖项和我用来初始化客户端的代码相关的pom.xml依赖项部分。

庞.xml

<dependency>
<groupId>org.elasticsearch</groupId>
<artifactId>elasticsearch</artifactId>
<version>7.7.0</version>
</dependency>
<dependency>
<groupId> org.elasticsearch.client</groupId>
<artifactId>elasticsearch-rest-high-level-client</artifactId>
<version>7.7.0</version>
</dependency>

和客户端启动代码

@Configuration
@Primary
public class ElasticsearchConfig {
/**
* Creates a Elasticsearch client from config
*
* @return Elasticsearch client
*/
@Bean(destroyMethod = "close")
public RestHighLevelClient client() {
RestHighLevelClient client = new RestHighLevelClient(
RestClient.builder(new HttpHost("localhost", 9500, "http")));
return client;
}
}

还有我的application properties

elasticsearch.host=localhost
elasticsearch.port=9500

Answer 3

在应用程序中配置 Elasticsearch时，我们需要定义如何连接到 Elasticsearch 实例。你可以像这样尝试 RestHighLevelClient -

@Configuration
@EnableElasticsearchRepositories(basePackages = "com.your.repo.package")
@ComponentScan(basePackages = { "com.your.package" })
public class Config {
@Bean
public RestHighLevelClient client() {
ClientConfiguration clientConfiguration 
= ClientConfiguration.builder()
.connectedTo("localhost:9200")
.build();
return RestClients.create(clientConfiguration).rest();
}
@Bean
public ElasticsearchOperations elasticsearchTemplate() {
return new ElasticsearchRestTemplate(client());
}
}

Answer 4

通过添加以下依赖项解决了这个问题。

compile group: 'org.elasticsearch', name: 'elasticsearch', version: '7.7.1'
compile group: 'org.elasticsearch.client', name: 'elasticsearch-rest-high-level-client', version: '7.7.1'
compile group: 'org.elasticsearch.client', name: 'elasticsearch-rest-client', version: '7.7.1'
compile group: 'org.elasticsearch.client', name: 'transport', version: '7.7.1'
