java-在命令行上运行Apache Ignite时无法创建Ignite组件
作者：互联网
当开始学习点火时,我最终将IntelliJ用作IDE,并且运行良好.但是,我需要将其移至超级计算机环境中,并且需要能够从命令行运行它,但是我的代码却无法找到所需的类.我使用maven创建了项目,并添加了入门指南中提到的适当依赖项.之后,我将项目打包为maven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,无法创建带有以下错误的点火组件：
Exception in thread "main" class org.apache.ignite.IgniteException: Failed to create Ignite component (consider adding ignite-spring module to classpath) [component=SPRING, cls=org.apache.ignite.internal.util.spring.IgniteSpringHelperImpl]

寻找其他类似的问题,我发现这是因为未能在pom文件中包含ignite-spring.但是我已经包括了.这是我的pom文件：

我要去哪里错了？重要的IDE导致某些事情变得不一致了吗？我运行代码的命令是否不完整或错误？谢谢您的帮助.如果需要,这里是发生错误的代码的第一行：
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");
...
}
}
}
解决方法:
我建议执行以下操作：
>将所有应用程序类(无Ignite依赖项)打包到JAR中,并将其放入IGNITE_HOME / libs文件夹中.
>将MAIN_CLASS环境变量设置为您的主类(com.mycompany.app.App).
>运行IGNITE_HOME / bin / ignite.sh脚本.它将使用所有必需的Ignite依赖关系正确地形成Java的classpath参数,并将运行您的应用程序.
