升级到elasticsearch 5.5.0和spring-data-elastic-version 3.0.2：ClassNotFoundException：org.springframework.data.querydsl.QuerydslUtils

Question

我正在尝试升级使用spring boot和spring data elasticsearch的应用程序。

  

spring boot-＆gt; 1.5.8.RELEASE从1.5.2.RELEASE   spring-data-elastic-version - ＆gt; 3.0.2.RELEASE来自2.1.3.RELEASE

这是我的主要应用程序文件代码（与elasticsearch相关）：

@SpringBootApplication
@EnableElasticsearchRepositories(basePackages = "org/springframework/data/elasticsearch/repositories")
 public class TeyeApplication extends WebMvcConfigurerAdapter {

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

@Bean
public Client client() throws UnknownHostException {
Settings settings =Settings.builder().put("cluster.name", "elasticsearch").build();
Client client = new PreBuiltTransportClient(settings).addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("localhost"), 9300));
return client;
}

当我运行应用程序时，它会出现以下异常：

我试图解决这个问题将近3天，但无法找到解决方案。
