当开始学习点燃时,我最终使用IntelliJ作为IDE,它一直运行良好。但是我需要将它移到超级计算机环境中,并且需要能够从命令行运行它,但是我的代码能够找到所需的类。我使用maven创建了我的项目,添加了正确的依赖项,如入门指南中所述。接下来,我有maven打包项目并使用以下命令:
/usr/java/jdk1.8.0_91/bin/java -cp "${IGNITE_HOME}/modules/core/target/ignite-core-1.6.0.jar:${IGNITE_HOME}/modules/core/target/libs/cache-api-1.0.0.jar:${IGNITE_HOME}/modules/spring/target/ignite-spring-1.6.0.jar:target/my-app-1.0-SNAPSHOT.jar" com.mycompany.app.App
但是,无法使用以下错误创建一个ignite组件:

寻找其他类似的问题,我看到它是因为没有在pom文件中包含ignite-spring。不过我已经包括了那个。这是我的pom文件:

我哪里错了?有重要的进入IDE造成的东西变得不一致吗?我的命令运行代码是不完整还是错误?谢谢您的帮助。如果需要,这里是我的代码中发生错误的第一行:
package com.mycompany.app;
import org.apache.ignite.Ignite;
import org.apache.ignite.IgniteCache;
import org.apache.ignite.Ignition;
import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
import java.net.URL;
import java.net.URLClassLoader;
import java.util.StringTokenizer;
public class App
{
public static void main( String[] args ) {
printClasspath();
String data;
try {
data = readFile("tweet.txt");
Ignite ignite = Ignition.start("/ignite-1.6.0/examples/config/example-ignite.xml");
IgniteCache<Integer, String[]> cache = ignite.getOrCreateCache("myCacheName");
...
}
}
}
答案 0 :(得分:2)
我建议您执行以下操作:
IGNITE_HOME/libs
文件夹。MAIN_CLASS
环境变量设置为主类(com.mycompany.app.App
)。IGNITE_HOME/bin/ignite.sh
脚本。它将正确地形成Java的classpath参数以及所有必需的Ignite依赖项,并将运行您的应用程序。答案 1 :(得分:2)
因为我们的java类没有标识类 请参阅以下命令
在UNIX上安装
apache-ignite-fabric-1.5.0-b1-bin解压缩此文件夹
在本例中,我的“apache-ignite-fabric-1.5.0-b1-bin”目录位于“/home/stp/ignite/apache-ignite-fabric-1.5.0-b1-bin"
HelloWorld程序示例:

此HelloWorld.java文件创建于“[stp @ ril-srv-sp4 apache-ignite-fabric-1.5.0-b1-bin] $ cd libs”location
在编译这个程序之前,我们必须在“/home/stp/ignite/apache-ignite-fabric-1.5.0-b1-bin/libs”文件夹和子文件夹中识别所有jar位置。
[stp@ril-srv-sp4 apache-ignite-fabric-1.5.0-b1-bin]$ cd libs
