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

问题

Hi Guys I'm newbie in Apache Ignite. I've tried to run it on Windows 10 Professional. I've run example-cache example in ignite directory as follows :

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

I've previously set IGNITE_HOME environment variable to

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

But I have this exception stack :

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

I've tried to set IGNITE_HOME to D:\work\tools\apache ignite 1.9.0\apache-ignite-fabric-1.9.0-bin\libs which contains the jar file ignite-spring-1.9.0.jar containing the class org.apache.ignite.internal.util.spring.IgniteSpringHelperImpl

回答1:

Try to set IGNITE_HOME to "D:\work\tools\apache ignite 1.9.0\apache-ignite-fabric-1.9.0-bin".

Or USER_LIBS to "D:\work\tools\apache ignite 1.9.0\apache-ignite-fabric-1.9.0-bin\libs" as it was suggested.

回答2:

I am just setting up Ignite and had exactly the same problem (I am in Ignite version 2.6 though).

I think I found a simple solution after debugging the shell scripts in $IGNITE_HOME/bin, particularly $IGNITE_HOME/bin/include/setenv.sh

The fix is to replace this line form setenv.sh:

IGNITE_LIBS="${IGNITE_HOME}/libs/*"

by this other line instead:

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

The reason this works IMHO is that IGNITE_LIBS is how the classpath is set in $IGNITE_HOME/bin/ignite.sh, in the line

CP="${IGNITE_LIBS}"

($CP is later used as the class path in a Java -cp $CP call).

And since the classpath wildcards are not recursive (see e.g. Set folder for classpath), there is basically a bug in the distribution because a classpath of $IGNITE_HOME/libs/* will never find $IGNITE_HOME/libs/ignite-spring/ignite-spring-2.6.0.jar which is the jar you need, I believe.
