@Marz(key = "feature.checkout")
private volatile boolean enabled = false;
// Value updates at runtime. No restart.
Add @Marz to any field — boolean, int, long, double, or String.
Point it at your config file.
Change the value in your YAML, JSON, or properties file. The WatchService detects the change instantly.
The field swaps in ~50ms. Next read sees the new value. No restart, no proxy, no bean rebuild.
@Service
public class CheckoutService {
@Marz(key = "feature.checkout.enabled",
source = "file://config/features.yml")
private volatile boolean newCheckoutEnabled = false;
// Edit the YAML → field updates in ~50ms
// No restart. No proxy. No @RefreshScope. Just volatile.
