title: Having spring bean properties refreshed automatically from properties file
body: <p>I'm using Spring 2.5.6.  I have a bean whose properties are being assign from a property file via a <a href="http://static.springframework.org/spring/docs/2.0.x/api/org/springframework/beans/factory/config/PropertyPlaceholderConfigurer.html" rel="noreferrer">PropertyPlaceholderConfigurer</a>. I'm wondering whether its possible to have the property of the bean updated when the property file is modified.  There would be for example some periodic process which checks the last modified date of the property file, and if it has changed, reload the bean.</p>
  
  <p>I'm wondering if there is already something that satisfies my requirements.  If not, what would be the best approach to solving this problem? </p>
  
  <p>Thanks for your help.</p>
