Question

嗨，大家好，我是Apache Ignite的新手。我试图在Windows 10 Professional上运行它。我在ignite目录中运行了example-cache示例，如下所示：

D:\work\tools\apache ignite 1.9.0\apache-ignite-fabric-1.9.0-bin>bin\ignite.bat examples\config\example-cache.xml

我之前已将IGNITE_HOME环境变量设置为

D:\work\tools\apache ignite 1.9.0\apache-ignite-fabric-1.9.0-bin

但我有这个异常堆栈：

Note! You may use 'USER_LIBS' environment variable to specify your classpath.

我已尝试将IGNITE_HOME设置为D:\work\tools\apache ignite 1.9.0\apache-ignite-fabric-1.9.0-bin\libs，其中包含包含类ignite-spring-1.9.0.jar的jar文件org.apache.ignite.internal.util.spring.IgniteSpringHelperImpl

Answer 1

尝试将IGNITE_HOME设置为“D：\ work \ tools \ apache ignite 1.9.0 \ apache-ignite-fabric-1.9.0-bin”。

或USER_LIBS到“D：\ work \ tools \ apache点燃1.9.0 \ apache-ignite-fabric-1.9.0-bin \ libs”，如建议的那样。

Answer 2

我只是在设置Ignite并遇到了完全相同的问题（尽管我使用的是Ignite 2.6版）。

我认为在调试$ IGNITE_HOME / bin中的shell脚本后，特别是$ IGNITE_HOME / bin / bin / include / setenv.sh

后，我找到了一个简单的解决方案

解决方法是替换此行形式setenv.sh：

IGNITE_LIBS =“ $ {IGNITE_HOME} / libs / *”

通过另一行代替：

IGNITE_LIBS =“ $ {IGNITE_HOME} / libs / *; $ {IGNITE_HOME} / libs / ignite-spring / *”

恕我直言，这是因为IGNITE_LIBS是在$ IGNITE_HOME / bin / ignite.sh的行中设置类路径的方式

CP =“ $ {IGNITE_LIBS}”

（$ CP稍后在Java -cp $ CP调用中用作类路径）。

并且由于类路径通配符不是递归的（请参见例如Set folder for classpath），因此分发中基本上存在一个错误，因为$ IGNITE_HOME / libs / *的类路径永远找不到$ IGNITE_HOME / libs / ignite-spring我相信/ignite-spring-2.6.0.jar是您需要的jar。

ClassNotFoundException：org.apache.ignite.internal.util.spring.IgniteSpringHelperImpl
