Override Spring's PropertyPlaceholderConfigurer with a karaf's etc's
config file
Hello,
My jar ( spring bundle ) has a default set of configurations via
<bean id="propertyConfigurer"
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="systemPropertiesModeName"
value="SYSTEM_PROPERTIES_MODE_OVERRIDE" />
<property name="location" value="classpath:com/.../resources.properties" />
</bean>
This way I can override the default properties using system
properties ( ie pass in -Dxuy=value to JVM )
Now I'd like to deploy my bundle to Karaf, is there a way for me to
setup Karaf/osgi's configAdmin to to use a config file under karaf's
etc directory to override my default properties?
Big thanks ahead.
-Dan

yes, I read that doc many times. and dont see anything point to what
I need. However, with Achim's help, I think i should refactor my
spring configuration.

Dan,
I hate to be an RTFM kind of guy, but we actually did a write up on how to
do this
http://karaf.apache.org/manual/2.1.99-SNAPSHOT/users-guide/provisioning.html
here .
Scroll down to the section on "Configuration", and it should give you the
information you're looking for. Please let us know if there's anything else
we can do for you.

Hi Achim,
Thanks for the extended offer. I am marching my way to OSGI
ConfigAdmin, Next I will walk to JMX way, i am very sure will need
more advice

Hi Achim,
I think it is reasonable to refactor my spring configuration to
separate standalone spring app and osgi app, rather then mixing them

Re: Override Spring's PropertyPlaceholderConfigurer with a karaf's
etc's config file
Posted by Achim Nierbeck <bc...@googlemail.com>.
Hi Dan,
depends on how you setup your Spring and your application.
I usually use maven as build system and therefore do differentiate
between spring in test and on server.
In you "test" environment you can keep your configuration.
One other possibility is how you tell spring / spring-dm which config
files to use.
Per default spring-dm searches for a spring xml file in META-INF/spring
but you can also
tell spring to search in other directories or just to use certain xml
files.
For example you might set the following in the MANIFEST
Spring-Context: config/account-data-context.xml, config/account-security-context.xml
More details on how to configure spring and so forth can be found at [1]
Another thing I usually do is to separate Spring bean wiring from it's
configuration, this way you can
use different configurations for different locations.

Hi Achim
what do you mean by "Now you just need to replace your property code
by the following."?
does this mean i need to remove my spring
<bean id="propertyConfigurer"
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="systemPropertiesModeName"
value="SYSTEM_PROPERTIES_MODE_OVERRIDE" />
<property name="location" value="classpath:com/.../resources.properties" />
</bean>
as well?
I am hoping to leave my spring config untouched until we fully
OSGIzing it, so that my current test still functional as standlone
spring test
Thank you

Re: Override Spring's PropertyPlaceholderConfigurer with a karaf's
etc's config file
Posted by Achim Nierbeck <bc...@googlemail.com>.
Hi Dan,
yes it is.
first of all you need to make sure you got a cfg file in your etc folder
with a name that matches a "PID" - PersistentID
e.g. my.very.special.resources.cfg
where my.very.special.resources is the pid.
This way the FileInstaller takes this cfg file and tells the config
admin service to provide a configuration for that pid.
Now you just need to replace your property code by the following.
<osgix:cm-properties id="cfg.with.defaults" persistent-id="my.very.special.resources">
<beans:prop key="host">localhost</beans:prop>
<beans:prop key="port">3306</beans:prop>
</osgix:cm-properties>
It can also be found at [1]
