Solving @Transactional Self-Invocation with ObjectProvider

Spring's @Transactional relies on AOP proxies. Calling a transactional method directly from within the same class bypasses the proxy. Using ObjectProvider to self-inject the bean ensures the call goes through the proxy.

snippet.java
java
@Service
public class OrderService {
    private final ObjectProvider<OrderService> self;
 
    public OrderService(ObjectProvider<OrderService> self) {
        this.self = self;
    }
 
    public void processOrder() {
        // Self-invocation via proxy to ensure @Transactional is honored
        self.getIfAvailable().saveToDatabase();
    }
 
    @Transactional
    public void saveToDatabase() {
        // Database logic here
    }
}

ObjectProvider<OrderService> self

Provides a lazy-loaded reference to the proxied version of the current bean.

self.getIfAvailable().saveToDatabase()
