how to access properties file in Spring

PropertyPlaceHolderConfigurer A property resource configurer that resolves placeholders in bean property values of context definitions. It pulls values from a properties file into bean definitions.

The default placeholder syntax follows the Ant / Log4J / JSP EL style: ‘$’

PropertyOverrideConfigurer A property resource configurer that overrides bean property values in an application context definition. It pushes values from a properties file into bean definitions
Example:
A simple class of which values are set from property file.


public class MyBean {
	private String myName;

	private String password;

	/**

	 * @param args

	 */

	public static void main(String[] args) {
		ClassPathXmlApplicationContext ctx = new ClassPathXmlApplicationContext("mybean.xml");

		MyBean bean = (MyBean)ctx.getBean("myBean");

		// getting the properties from the property file

		System.out.println(bean.getMyName());

		System.out.println(bean.getPassword());

	}

	public String getMyName() {

		return myName;

	}

	public void setMyName(String myName) {

		this.myName = myName;

	}

	public String getPassword() {

		return password;

	}

	public void setPassword(String password) {

		this.password = password;

	}

}
