Question

我有一个主要方法的拓扑类。它启动zookeeper并在eclispe中运行右键单击运行作为java应用程序。但我正在尝试它能够运行我尝试过的批处理文件

java -classpath jar-with-classes-and-dependency.jar com.demo.Topology

但这给了我这样的例外。

Exception in thread "main" java.lang.NoClassDefFoundError:

我认为这是缺少任何依赖。请帮助您运行此拓扑类。

尝试像这样跑......

pathToStorm/bin/storm jar ./target/jar-with-classes-and-dependency.jar com.demo.Topology.

请记住，在执行此步骤之前，您应该构建jar。你可以通过运行来构建你的jar 您的pom.xml文件所在的风暴项目中的mvn clean install。

如何通过命令提示符运行Storm Topology类？
