【问题描述】:
在我的 maven-Spring 项目中,我尝试连接到 ElasticSearch: TransportClient esclient = TransportClient.builder().build() .addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("localhost"), 9300));
我添加了 maven 依赖项 - org.elasticsearch 2.4.5
我不断得到: Servlet 调度程序的 Servlet.service() 抛出异常 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) 在 sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) 在 sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) 在 sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) 在 java.lang.reflect.Method.invoke(Method.java:498) 在 org.springframework.web.method.support.InvocableHandlerMethod.doInvoke(InvocableHandlerMethod.java:221)
要摆脱这个异常: 我尝试添加 Guava 18.0 依赖项,在 org.elasticSearch 中添加排除项以及为 maven 添加阴影番石榴。
不添加番石榴依赖或排除,这是我的依赖:树

好吧,我没有你想念什么,但我们想念的显然是更多信息!你得到什么异常,你可能只链接了消息,而不是异常本身。所以编辑你的问题,添加你拥有的所有信息,所有你的 Maven 配置,并告诉我们到底发生了什么。

嗨 Olivier,我用所需的信息更新了我的评论。
-
你在 Guava 上有依赖冲突。
MoreExecutors.directExecutor()方法是在 Guava 18 中添加的。因此,当您执行应用程序时,您的类路径中可能有一个版本低于 18 的 Guava。在类路径上意味着:在您的 maven 配置中(直接或间接),因此请创建一个mvn dependency:tree以了解您的 maven 配置中是否有更多 Guava 实例。如果没有,请检查应用程序运行器的类路径(在本例中为 Glassfish)。 -
嗨 Olivier,我用dependency:tree 更新了这个问题。
