Check out this framework. Seems you're looking for something like this.

public class WeatherServiceProxy {
...
private final KeyLockManager lockManager = KeyLockManagers.newManager();

public void updateWeatherData(String cityName, Date samplingTime, float temperature) {
        lockManager.executeLocked(cityName, new LockCallback() {
                public void doInLock() {
                        delegate.updateWeatherData(cityName, samplingTime, temperature);
                }
        });
}
