從Maven項目連接到彈性搜索時出現問題

Question

在我的maven-Spring項目中，我嘗試通過以下方式連接到ElasticSearch：TransportClient esclient = TransportClient.builder（）。build（）.addTransportAddress（new InetSocketTransportAddress（InetAddress.getByName（“ localhost”），9300））;

我添加了Maven依賴-org.elasticsearch 2.4.5

我不斷得到： Servlet調度程序的Servlet.service（）拋出異常java.lang.NoSuchMethodError：com.google.common.util.concurrent.MoreExecutors.directExecutor（）Ljava / util / concurrent / Executor; 在org.elasticsearch.threadpool.ThreadPool。（ThreadPool.java:192）在org.elasticsearch.client.transport.TransportClient $ Builder.build（TransportClient.java:133）在com.controller.AppController.loginPage（AppController.java： 204）at sun.reflect.NativeMethodAccessorImpl.invoke0（本地方法）at java.lang.reflect處sun.reflect.NativeMethodAccessorImpl.invoke（NativeMethodAccessorImpl.java:62）at sun.reflect.DelegatingMethodAccessorImpl.invoke（DelegatingMethodAccessorImpl.java:43） org.springframework.web.method.support上的.Method.invoke（Method.java:498）.InvocableHandlerMethod.doInvoke（InvocableHandlerMethod.java:221）

要擺脫此異常：我嘗試添加Guava 18.0依賴關系，在org.elasticSearch中添加排除項，並為maven添加陰影番石榴。

沒有添加番石榴依賴或排除，這是我的依賴：樹

Answer 1

在查看更多內容后，我發現GlassFish自己的依賴項泄漏到應用程序類路徑中（並且GF使用了較舊的Guava），因此，針對Glassfish4.1用戶的解決方法是使用guava 19版本更新/ glassfish / modules中的guava.jar。

使用此依賴項：

<dependency>
    <groupId>org.glassfish.jersey.bundles.repackaged</groupId>
    <artifactId>jersey-guava</artifactId>
    <version>2.19</version>
</dependency>

由於解決此問題需要干預GF自己的庫並且容易出錯，因此我移至Tomcat，並且無需進行其他更改即可正常工作。
