I am trying to execute shell script with camel and tried the following code, everything is looking fine its starting the route but I have following 2 issues

  1. Shell script file is not picking and executing the commands in it.
  2. Not even getting log messages that I kept all over in my code.

following is the route that I am using

@component
public class ShellRoute extends RouteBuilder
{
@override
public void configure()
{
final Logger logger = LoggerFactory.getLogger(ShellRoute.class);
logger.info("shellRoute");

boolean startupRoute=true;

from("direct:start")
.log(LoggingLevel.INFO, "Enter into Route:")
.routeID("ShellRoute")
.autoStartup(startupRoute)
.onException(Exception.class);
.logExhausted(false)
.logStackTrace(false)
.end()
.log(LoggingLevel.INFO, "Starting Script:")
.to("exec:./run_setup.sh?args=dev")
.log(LoggingLevel.INFO, "End of Script:");
}
}

Following is the Log:

To execute shell script command in Apache camel, As per the exec component documentation http://camel.apache.org/exec.html

The following example executes Apache Ant (Windows only) with the build file CamelExecBuildFile.xml, provided that ant.bat is in the system path, and that CamelExecBuildFile.xml is in the current directory.

from("direct:exec").to("exec:ant.bat?args=-f CamelExecBuildFile.xml")

So similarly from("direct:exec").to("exec:{path}/Cygwin/bin/bash?args=run_setup.sh")

  • Hi ManishGupta It's not working, problem here in this route is, route is starting as I gave .autoStartup(startupRoute) But whatever in the route it may be "exec" or "simple file transfer" its not happening Do I need to register this route somewhere to execute commands in the route Please let me know, i am new to camel. – mani ratnam Sep 30 '17 at 07:04
  • A good idea is to study the beginner examples of Apache Camel if you are new to Camel: https://github.com/apache/camel/tree/master/examples#examples – Claus Ibsen Oct 03 '17 at 17:31

The direct endpoint provides synchronous invocation of a route. So you have to invoke the route for the script to execute. Have a look at this answer for invoking routes. Apache Camel : "direct:start" endpoint - what does it mean ?

If you want it to execute just one time at the startup you can replace 

from("direct:exec")

with something like

from("timer://runOnce?repeatCount=1&delay=5000")
