我在SpringBoot應用程序中創建HighEndRestClient bean時出錯。我做了一個測試「應用程序」，在那裏我檢查了我可以實例化我想要的對象，然後進行我想要的調用，現在我正在開發一個新的應用程序。NoClassDefFoundError錯誤創建RestHighLevelClient bean
我在POM
<dependency>
<groupId>org.elasticsearch.client</groupId>
<artifactId>elasticsearch-rest-client</artifactId>
<version>5.6.3</version>
</dependency>
<dependency>
<groupId>org.elasticsearch.client</groupId>
<artifactId>elasticsearch-rest-high-level-client</artifactId>
<version>5.6.3</version>
</dependency>
這些依賴關係，我已經寫在配置類這個非常基本的代碼沒有做太多尚未
@Configuration
@PropertySource(value = "classpath:application.properties")
@EnableElasticsearchRepositories(basePackages = "com.indexbuilder.es.repo")
public class ElasticsearchConfiguration {
@Value("${elasticsearch.host}")
private String EsHost;
@Value("${elasticsearch.port}")
private int EsPort;
@Value("${elasticsearch.clustername}")
private String EsClusterName;
@Bean
public RestClientBuilder coreBuilder() throws Exception {
RestClientBuilder builder = RestClient.builder(new HttpHost("localhost", 9200, "http"));
builder.setMaxRetryTimeoutMillis(10000);
builder.setFailureListener(new RestClient.FailureListener() {
@Override
public void onFailure(HttpHost host) {
System.out.println("FAILURE !!!! FailureListener HAS WOKEN UP!!!! CREATYE A FAILURE LISTENER BEAN");
}
});
return builder;
}
@Bean
public RestClient restLowLevelClient() throws Exception{
RestClient restClient = coreBuilder().build();
return restClient;
}
這工作得很好，只要我可以看到（我還沒有做過多的工作呢......）
當我添加這個（最初我傳遞RestClient bean，但現在我暫時創建一個本地對象更多clarit Y）
@Bean
public RestHighLevelClient restHighLevelClient() throws Exception{
RestClient restClient = coreBuilder().build();
RestHighLevelClient client = new RestHighLevelClient(restClient);
return client;
}
我得到這個java.lang.NoClassDefFoundError錯誤

任何人都可以點我在正確的方向？
