Re: Enable disable routes at startup using Spring

[javaCzar]

Willem,

Thanks for the assist. To aid anyone else that might follow this trhead,
here is what I ended up implementing:

start applicaiton with something like -Denvironment=dev or 
-Denvironment=prod

main context xml uses:
import resource=some-context-${environment}.xml/

to import either some-context-dev.xml or some-context-prod.xml

some-context-dev.xml defines:
routeContext id=aContext xmlns=http://camel.apache.org/schema/spring;
   
/routeContext

and some-context-prod.xml defines:
routeContext id=aContext xmlns=http://camel.apache.org/schema/spring;
   
/routeContext

Re: Enable disable routes at startup using Spring

[javaCzar]

Willem,

I am loading the properties in a bean:

bean id=propLoader class=com.aaa.bbb.ccc.PropLoader/

public class PropLoader extends BridgePropertyPlaceholderConfigurer {
   ...
Properties props = new Properties();
for (String prop : myProperties.getPropertyNames()) {
if (prop != null) {
// this loads the property enableRoute with value
true or false
props.setProperty(prop, myProperties.getValue(prop));
}
}
super.setProperties(props);
   ...
}

this bean is in the depends-on for the camelContext:

camelContext xmlns=http://camel.apache.org/schema/spring; trace=true
depends-on=propLoader,otherbean
   route autoStartup=${enableRoute}
   ...
   /route
/camelContext

I am basing this off of info from:

http://camel.apache.org/how-do-i-use-spring-property-placeholder-with-camel-xml.html

I tried to use the {{enableRoute}} naming you mentioned, and I no longer get
the exception; however, it does not seem to take because the route starts
regardless of the value I set. I'm pretty sure that {{enableRoute}} is not
getting the correct value that I am setting via the Spring
BridgePropertyPlaceholderConfigurer.

Thanks again for the assistance.

JC

Re: Enable disable routes at startup using Spring

Willem,

My error in the last post. Your assitance with the {{xxx}} naming was
correct. The variable is being set correctly and can be accessed bia this
naming.

I thought is was not working because what I am seeing that with
autoStartup=false the endpoint still initializes, just the incoming data
is not sent to the rest of the route.

So, I guess this brings me to a second question. Is there a way to not
initialize the endpoint via configuration. The reason that I need is for the
following. I have an endpoint (QuickFIXj) that should not be connecting in
certain circumstances For example, testing and dev instances should not
attemtp to connect to a FIX server via this endpoint. However, prod
instances need to have this enabled. 

I would imagine that this scenario exixst for many connection based
services/endpoints. Is there a way to configure the camelContext with what
essentially would work like old school compiler derectives:

something along the lines of: 

camelContext
   route
  
   /route
#ifdef PROD
   route
  
   /route
#endif  
/camelContext

Again, I know this code above is not valid, just an example of what I would
need it to work like. As if it was not even there when not in prod.

Thanks.

Enable disable routes at startup using Spring

[javaCzar]

Is there a way to get something like this to work:

route autoStartup=${enableRoute}

The value of the attribute is set to a valid parsible string representation
of a boolean (ie. true or false) yet I keep getting the following error:

org.apache.camel.RuntimeCamelException:
org.apache.camel.FailedToCreateRouteException: Failed to create route
route8: Route[[From[quickfix:quickfix.cfg]] - [Filter[s... because of Error
parsing [${enableRoute}] from property ${enableRoute} as a Boolean.

Any assistnace would be greatly appreciated.
