Examples of PropertyPlaceholderConfigurer

• org.springframework.beans.factory.config.PropertyPlaceholderConfigurer
  {@link PlaceholderConfigurerSupport} subclass that resolves ${...} placeholdersagainst {@link #setLocation local} {@link #setProperties properties} and/or system propertiesand environment variables.

  As of Spring 3.1, {@link org.springframework.context.support.PropertySourcesPlaceholderConfigurer PropertySourcesPlaceholderConfigurer} should be used preferentially over this implementation; it ismore flexible through taking advantage of the {@link org.springframework.core.env.Environment Environment} and{@link org.springframework.core.env.PropertySource PropertySource} mechanisms also made available in Spring 3.1.

  {@link PropertyPlaceholderConfigurer} is still appropriate for use when:

  • the {@code spring-context} module is not available (i.e., one is using Spring's{@code BeanFactory} API as opposed to {@code ApplicationContext}).
  • existing configuration makes use of the {@link #setSystemPropertiesMode(int) "systemPropertiesMode"} and/or{@link #setSystemPropertiesModeName(String) "systemPropertiesModeName"} properties. Users are encouraged to moveaway from using these settings, and rather configure property source search order through the container's {@code Environment}; however, exact preservation of functionality may be maintained by continuing to use {@code PropertyPlaceholderConfigurer}.

  Prior to Spring 3.1, the {@code } namespace elementregistered an instance of {@code PropertyPlaceholderConfigurer}. It will still do so if using the {@code spring-context-3.0.xsd} definition of the namespace. That is, you can preserveregistration of {@code PropertyPlaceholderConfigurer} through the namespace, even if using Spring 3.1;simply do not update your {@code xsi:schemaLocation} and continue using the 3.0 XSD. @author Juergen Hoeller @author Chris Beams @since 02.10.2003 @see #setSystemPropertiesModeName @see PlaceholderConfigurerSupport @see PropertyOverrideConfigurer @see org.springframework.context.support.PropertySourcesPlaceholderConfigurer
