use apache common with spring as follow:

@Component
public class ApplicationProperties {
    private PropertiesConfiguration configuration;

    @PostConstruct
    private void init() {
        try {
            String filePath = "/opt/files/myproperties.properties";
            System.out.println("Loading the properties file: " + filePath);
            configuration = new PropertiesConfiguration(filePath);

            //Create new FileChangedReloadingStrategy to reload the properties file based on the given time interval
            FileChangedReloadingStrategy fileChangedReloadingStrategy = new FileChangedReloadingStrategy();
           fileChangedReloadingStrategy.setRefreshDelay(60*1000);
            configuration.setReloadingStrategy(fileChangedReloadingStrategy);
        } catch (ConfigurationException e) {
            e.printStackTrace();
        }
    }

    public String getProperty(String key) {
        return (String) configuration.getProperty(key);
    }

    public void setProperty(String key, Object value) {
        configuration.setProperty(key, value);
    }

    public void save() {
        try {
            configuration.save();
        } catch (ConfigurationException e) {
            e.printStackTrace();
        }
    }
}
