在命令行上運行Apache Ignite時無法創建Ignite組件

Question

當開始學習點燃時，我最終使用IntelliJ作為IDE，它一直工作正常。 但是我需要將它移到超級計算機環境中，並且需要能夠從命令行運行它，但是我的代碼能夠找到所需的類。 我使用maven創建了我的項目，添加了正確的依賴項，如入門指南中所述。 接下來，我有maven打包項目並使用以下命令：

/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，它無法創建具有以下錯誤的ignite組件：

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]

尋找其他類似的問題，我已經看到它是因為沒有在pom文件中包含ignite-spring。 不過我已經包括了那個。 這是我的pom文件：

我哪里錯了？ 有重要的進入IDE造成的東西變得不一致嗎？ 我的命令運行代碼是不完整還是錯誤？ 謝謝您的幫助。 如果需要，這里是我的代碼中發生錯誤的第一行：

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");
        ...
        }
     }
}

Answer 1

我建議做以下事情：

1. 將所有應用程序類（沒有Ignite依賴項） IGNITE_HOME/libs到JAR中並將其放入IGNITE_HOME/libs文件夾中。
2. 將MAIN_CLASS環境變量設置為主類（ com.mycompany.app.App ）。
3. 運行IGNITE_HOME/bin/ignite.sh腳本。 它將正確地形成Java的classpath參數以及所有必需的Ignite依賴項，並將運行您的應用程序。

Answer 2

因為我們的java類沒有標識類請參閱以下命令

在UNIX上安裝

1. 下載https://ignite.apache.org/download.cgi網站

2. apache-ignite-fabric-1.5.0-b1-bin解壓縮此文件夾

   在這個例子中，我的“apache-ignite-fabric-1.5.0-b1-bin”目錄位於“/home/stp/ignite/apache-ignite-fabric-1.5.0-b1-bin”

3. HelloWorld程序示例：

    //program starting################################################################################################################################# import org.apache.ignite.Ignite; import org.apache.ignite.IgniteException; import org.apache.ignite.Ignition; import org.apache.ignite.IgniteCache; //import org.apache.ignite.internal.util.spring; public class HelloWorld { public static void main(String[] args) throws IgniteException { try (Ignite ignite = Ignition.start("/home/stp/ignite/apache-ignite-fabric-1.5.0-b1-bin/examples/config/example-ignite.xml")) { // Put values in cache. IgniteCache<Integer, String> cache = ignite.getOrCreateCache("myCache"); cache.put(1, "Hello"); cache.put(2, "World"); cache.put(3,"Durga Prasad"); // Get values from cache // Broadcast 'Hello World' on all the nodes in the cluster. ignite.compute().broadcast(()->System.out.println(cache.get(1) + " " + cache.get(2) + " " +cache.get(3))); } } } //end program ###################################################################################################################### 

4. 此HelloWorld.java文件在“[stp @ ril-srv-sp4 apache-ignite-fabric-1.5.0-b1-bin] $ cd libs”位置創建

   在編譯這個程序之前，我們必須在“/home/stp/ignite/apache-ignite-fabric-1.5.0-b1-bin/libs”文件夾中以及子文件夾中識別所有jar位置。

    [stp@ril-srv-sp4 apache-ignite-fabric-1.5.0-b1-bin]$ cd libs javac -cp "/home/stp/ignite/apache-ignite-fabric-1.5.0-b1-bin/libs/ignite-core-1.5.0-b1.jar:/home/stp/ignite/apache-ignite-fabric-1.5.0-b1-bin/libs/cache-api-1.0.0.jar:/home/stp/ignite/apache-ignite-fabric-1.5.0-b1-bin/libs/ignite-shmem-1.0.0.jar:/home/stp/ignite/apache-ignite-fabric-1.5.0-b1-bin/libs/ignite-indexing/commons-codec-1.6.jar:/home/stp/ignite/apache-ignite-fabric-1.5.0-b1-bin/libs/ignite-indexing/h2-1.3.175.jar:/home/stp/ignite/apache-ignite-fabric-1.5.0-b1-bin/libs/ignite-indexing/ignite-indexing-1.5.0-b1.jar:/home/stp/ignite/apache-ignite-fabric-1.5.0-b1-bin/libs/ignite-indexing/lucene-core-3.5.0.jar:/home/stp/ignite/apache-ignite-fabric-1.5.0-b1-bin/libs/ignite-spring/commons-logging-1.1.1.jar:/home/stp/ignite/apache-ignite-fabric-1.5.0-b1-bin/libs/ignite-spring/spring-beans-4.1.0.RELEASE.jar:/home/stp/ignite/apache-ignite-fabric-1.5.0-b1-bin/libs/ignite-spring/spring-expression-4.1.0.RELEASE.jar:/home/stp/ignite/apache-ignite-fabric-1.5.0-b1-bin/libs/ignite-spring/ignite-spring-1.5.0-b1.jar:/home/stp/ignite/apache-ignite-fabric-1.5.0-b1-bin/libs/ignite-spring/spring-context-4.1.0.RELEASE.jar:/home/stp/ignite/apache-ignite-fabric-1.5.0-b1-bin/libs/ignite-spring/spring-jdbc-4.1.0.RELEASE.jar:/home/stp/ignite/apache-ignite-fabric-1.5.0-b1-bin/libs/ignite-spring/spring-aop-4.1.0.RELEASE.jar:/home/stp/ignite/apache-ignite-fabric-1.5.0-b1-bin/libs/ignite-spring/spring-core-4.1.0.RELEASE.jar:/home/stp/ignite/apache-ignite-fabric-1.5.0-b1-bin/libs/ignite-spring/spring-tx-4.1.0.RELEASE.jar" HelloWorld.java 

5. 使用“HelloWorld.class”創建一個jar文件

    jar -cf HelloWorld.jar HelloWorld.class 

6. 與類一起運行此jar文件

    [stp@ril-srv-sp4 libs]$ java -cp "/home/stp/ignite/apache-ignite-fabric-1.5.0-b1-bin/libs/ignite-core-1.5.0-b1.jar:/home/stp/ignite/apache-ignite-fabric-1.5.0-b1-bin/libs/cache-api-1.0.0.jar:/home/stp/ignite/apache-ignite-fabric-1.5.0-b1-bin/libs/ignite-shmem-1.0.0.jar:/home/stp/ignite/apache-ignite-fabric-1.5.0-b1-bin/libs/ignite-indexing/commons-codec-1.6.jar:/home/stp/ignite/apache-ignite-fabric-1.5.0-b1-bin/libs/ignite-indexing/h2-1.3.175.jar:/home/stp/ignite/apache-ignite-fabric-1.5.0-b1-bin/libs/ignite-indexing/ignite-indexing-1.5.0-b1.jar:/home/stp/ignite/apache-ignite-fabric-1.5.0-b1-bin/libs/ignite-indexing/lucene-core-3.5.0.jar:/home/stp/ignite/apache-ignite-fabric-1.5.0-b1-bin/libs/ignite-spring/commons-logging-1.1.1.jar:/home/stp/ignite/apache-ignite-fabric-1.5.0-b1-bin/libs/ignite-spring/spring-beans-4.1.0.RELEASE.jar:/home/stp/ignite/apache-ignite-fabric-1.5.0-b1-bin/libs/ignite-spring/spring-expression-4.1.0.RELEASE.jar:/home/stp/ignite/apache-ignite-fabric-1.5.0-b1-bin/libs/ignite-spring/ignite-spring-1.5.0-b1.jar:/home/stp/ignite/apache-ignite-fabric-1.5.0-b1-bin/libs/ignite-spring/spring-context-4.1.0.RELEASE.jar:/home/stp/ignite/apache-ignite-fabric-1.5.0-b1-bin/libs/ignite-spring/spring-jdbc-4.1.0.RELEASE.jar:/home/stp/ignite/apache-ignite-fabric-1.5.0-b1-bin/libs/ignite-spring/spring-aop-4.1.0.RELEASE.jar:/home/stp/ignite/apache-ignite-fabric-1.5.0-b1-bin/libs/ignite-spring/spring-core-4.1.0.RELEASE.jar:/home/stp/ignite/apache-ignite-fabric-1.5.0-b1-bin/libs/ignite-spring/spring-tx-4.1.0.RELEASE.jar:/home/stp/ignite/apache-ignite-fabric-1.5.0-b1-bin/libs/HelloWorld.jar" HelloWorld [14:14:26] __________ ________________ [14:14:26] / _/ ___/ |/ / _/_ __/ __/ [14:14:26] _/ // (7 7 // / / / / _/ [14:14:26] /___/\\___/_/|_/___/ /_/ /___/ [14:14:26] [14:14:26] ver. 1.5.0-b1#20151202-sha1:062d440c [14:14:26] 2015 Copyright(C) Apache Software Foundation [14:14:26] [14:14:26] Ignite documentation: http://ignite.apache.org [14:14:26] [14:14:26] Quiet mode.

7. 使用example-ignite.xml文件打開另一個終端

    [stp@ril-srv-sp4 bin]$ ./ignite.sh "/home/stp/ignite/apache-ignite-fabric-1.5.0-b1-bin/examples/config/example-ignite.xml" OpenJDK 64-Bit Server VM warning: ignoring option MaxPermSize=256m; support was removed in 8.0 [14:14:17] __________ ________________ [14:14:17] / _/ ___/ |/ / _/_ __/ __/ [14:14:17] _/ // (7 7 // / / / / _/ [14:14:17] /___/\\___/_/|_/___/ /_/ /___/ [14:14:17] [14:14:17] ver. 1.5.0-b1#20151202-sha1:062d440c [14:14:17] 2015 Copyright(C) Apache Software Foundation [14:14:17] [14:14:17] Ignite documentation: http://ignite.apache.org [14:14:17] [14:14:17] Quiet mode.
