从 Maven 项目连接到弹性搜索的问题

Question

在我的 maven-Spring 项目中，我正在尝试连接到 ElasticSearch： TransportClient esclient = TransportClient.builder().build() .addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("localhost"), 9300));

我添加了 maven 依赖 - org.elasticsearch 2.4.5

我不断收到： Servlet.service() 用于 servlet 调度程序抛出异常 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（本机方法）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：我尝试添加番石榴 18.0 依赖项，在 org.elasticSearch 中添加排除项，并为 Maven 着色番石榴。

不添加番石榴依赖或排除，这是我的dependency:tree

Answer 1

仔细查看后，我发现 GlassFish 自身的依赖项泄漏到应用程序类路径中（并且 GF 使用较旧的 Guava）因此 Glassfish4.1 用户的修复将更新 /glassfish/modules 中的 guava.jar番石榴 19 版本。

使用此依赖项：

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

由于解决这个问题需要干预 GF 自己的库并且容易出错，我搬到了 Tomcat 并且没有其他更改它工作正常。
