Resource Bundle In Spring: Dynamically Loading The Values For Property Placeholders In XML

Spring » on Feb 11, 2012 { 5 Comments } By Sivateja

Let us see how to load the values into spring configuration file dynamically using ResourceBundle concept

  • Instead of directly placing the values into xml we can load the values at run time for the dataSource properties using ResourceBundle
  • If we want to get the dataSource properties at runtime from ResourceBundle, while configuring the bean into xml we should put bundle keys with expression language into the xml file like…
<bean id="id1" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
    <property name="driverClassName">

In ResourceBundle

jdbc.driver = sun.jdbc.odbc.JdbcOdbcDriver

  •  In spring we have pre-defined class given, called PropertyPlaceholderConfigure and this class will read the data from the bundle and it will write the values into the configuration file
  • PropertyPlaceholderConfigure given in
    org.springframework.beans.factory.config.* package


Resource res = new ClassPathResource("spconfig.xml");
XmlBeanFactory factory = new XmlBeanFactory(res);

PropertyPlaceholderConfigur ppc = new PropertyPlaceholderConfigurer();
ppc.setLocation(new ClassPathResource(;

At line number 5, there spring container will read the properties file from bundle.

At line number 6, spring container will write the properties into XML file

Now will see one example..
