PropertiesConfiguration doesn't want to reload

Question

i would like to have my properties file to be reloaded every xx seconds. My code :

...
configuration = new PropertiesConfiguration();
configuration.setFileName(filename);

if (configuration.getFile().exists()) {
    configuration.load();

    final FileChangedReloadingStrategy strategy = new FileChangedReloadingStrategy();
    strategy.setRefreshDelay(3000);
    configuration.setReloadingStrategy(strategy);
} else {
    LOGGER.warn("Configuration file '{}' not found", filename);
}
...

But my file is never reloaded :( any idea?

Edit : Actually i think my problem comes from the fact that i override the load() method :

private static final class SystemPropertiesConfiguration extends PropertiesConfiguration {


    public SystemPropertiesConfiguration(String fileName) throws ConfigurationException
    {
        super(fileName);
    }

    @Override
    public synchronized void load(final Reader in) throws ConfigurationException {
        super.load(in);

        if (LOGGER.isDebugEnabled()) {
            LOGGER.debug("Updating system properties");
        }

        final boolean debugEnabled = LOGGER.isDebugEnabled();
        final Iterator<String> ite = getKeys();
        String key;

        while (ite.hasNext()) {
            key = ite.next();

            if (debugEnabled) {
                LOGGER.debug("Updating system property: {}", key);
            }

            System.setProperty(key, getString(key));
        }
    }
}

The purpose is actually to push the properties in System. So my question is : is the FileChangedReloadingStrategy calls the PropertiesConfiguration.load() method?

确保更改了部署目录中的文件而不是IDE中的源文件。
