Question

我试图将弹性搜索集成到spring-boot应用程序中，但我得到了这个*错误创建名为'client'的bean *异常，不确定出了什么问题因为我以前找不到任何类似的路径...... 非常感谢指导人们。这是mu elasticsearch配置：

这是我的主要申请：

    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
}


allprojects {
   repositories {
    jcenter()
}

我的pom.xml：

import org.elasticsearch.client.Client;
import org.elasticsearch.client.transport.TransportClient;
import org.elasticsearch.common.settings.Settings;
import org.elasticsearch.common.transport.InetSocketTransportAddress;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.elasticsearch.core.ElasticsearchOperations;
import org.springframework.data.elasticsearch.core.ElasticsearchTemplate;
import org.springframework.data.elasticsearch.repository.config.EnableElasticsearchRepositories;
import org.elasticsearch.transport.client.PreBuiltTransportClient;

import java.net.InetAddress;

@Configuration
@EnableElasticsearchRepositories(basePackages = "com.backend.project.repositories")
public class EsConfig {


@Bean
public Client client() throws Exception{
    TransportClient client = new PreBuiltTransportClient(Settings.EMPTY)
    .addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("elasticsearch.host"), 9200));    
    return client;
}

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

这是异常追踪：

@Configuration

@Autowired

@Autowired
private BookService bookService;

public static void main(String args[]) {
    SpringApplication.run(WebApplication.class, args);
}

@Override
public void run(String... args) throws Exception {

    printElasticSearchInfo();

    bookService.save(new Book("1001", "Elasticsearch Basics", "Rambabu Posa", "23-FEB-2017"));
    bookService.save(new Book("1002", "Apache Lucene Basics", "Rambabu Posa", "13-MAR-2017"));
    bookService.save(new Book("1003", "Apache Solr Basics", "Rambabu Posa", "21-MAR-2017"));

    //fuzzey search
    Page<Book> books = bookService.findByAuthor("Rambabu", new PageRequest(0, 10));

    //List<Book> books = bookService.findByTitle("Elasticsearch Basics");

    books.forEach(x -> System.out.println(x));


}

//useful for debug, print elastic search details
private void printElasticSearchInfo() {

    System.out.println("--ElasticSearch--");
    Client client = es.getClient();
    Map<String, String> asMap = client.settings().getAsMap();

    asMap.forEach((k, v) -> {
        System.out.println(k + " = " + v);
    });
    System.out.println("--ElasticSearch--");
}}

Answer 1

除了添加elasticsearch客户端依赖项之外，还需要添加elasticsearch依赖项：

    <dependency>
        <groupId>org.elasticsearch</groupId>
        <artifactId>elasticsearch</artifactId>
        <version>2.4.0</version>
    </dependency>

对于你的依赖;确保：

您在计算机上运行的是与pom.xml中所述相同的ES版本
您运行的ES版本和弹簧数据与您正在使用的Spring Boot App版本兼容。

AFAIK Spring Boot 1.5.2与ES 5.x或6.x不兼容所以我会考虑使用以前版本的ES或将Spring Boot升级到支持ES 5.x和6的2.0.0。 X

Answer 2

在 pom.xml 中添加来自 elasticsearch 的最新版本你可以这样使用

如果使用这个依赖

    <dependency>
        <groupId>org.springframework.data</groupId>
        <artifactId>spring-data-elasticsearch</artifactId>
    </dependency>

或者这样，如果使用这个依赖：

    <dependency>
    <groupId>org.elasticsearch</groupId>
    <artifactId>elasticsearch</artifactId>
    </dependency>

或同时使用。
