Externalize Properties File in a Java Web Application

To be able to load properties file from a file system rather than bundling it with your web application you should do the following:

   1.      Define “application base” or “property file location” as a context parameter in web.xml

  <context-param>

      <param-name>app.base</param-name>

      <param-value>file:///c:/my/app</param-value>

  </context-param>

            2.      Load all properties file using Spring’s PropertyPlaceholderConfigurer.

 

<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">

<property name="locations">

    <list>

         <value>${app.base}/myapp-app.properties</value>

         <value>${app.base}/myapp-db.properties</value>

    </list>

</property>

</bean>

If you know any other way of doing it, please leave a comment.
