How to call karaf console command in Java

问题:

If I want to execute a karaf shell command in my plugin (java), how to do it?

ex: opendaylight-user@root> snmp4sdn:printdb

"org.apache.felix.service.command.CommandProcessor" can handle it ?

回答1:

In Karaf 3, you have to use the Felix Gogo services, ie the CommandProcessor.

From a CommandProcessor, you can create a CommandSession and then call execute on this session.

Two notes on this:

• In Karaf4, the service has changed - it's not dependent on Gogo anymore
• All the shell commands use an underlying osgi service. It's always better to use this service instead of creating command and "parsing the outputstream". For example, you can install a Bundle with BundleContext.installBundle or install a feature through the FeaturesService

Your command, for example, use the org.opendaylight.snmp4sdn.ICore service. See: PrintDB
