How to use a system property in applicationContext.xml

[dhardiker]

Hi,

I would like to create an uber-jar of my application that utilises Spring, Hibernate and Lucene, and have the end user specify the path to where the lucene indexes can be stored using a -D command line variable.

The place I want to put it is here, in my applicationContext.xml: <prop key="hibernate.search.default.indexBase">/chosen/path/to/indexes</prop>

Any ideas?

Thanks!

Register a PropertyPlaceHolderConfigurer and put ${} around the property yyou wnat.

<bean class="rg.springframework.beans.factory.config.PropertyPlaceHolderConfigurer"/>

<prop key="hibernate.search.default.indexBase">${luceneIndexes}</prop>

Now if you start it with -DluceneIndexes=/your/location, the files will be stored in your location.

You could also let the PropertyPlaceHolderConfigurer read a property file in a specified conf directory and let it read the property from there.

Does this work for you?

<prop key="hibernate.search.default.indexBase">${indexBase}</prop>

Then include a PropertyPlaceholderConfgurer. You can also strategise the system property behaviour with the systemPropertiesMode property of that object.
