Rule Registry

The SpringRuleRegistry is a registry backed by the Spring application context. Instead of maintaining its own internal collection, it delegates directly to ListableBeanFactory — your rules are Spring beans, and the registry queries them as such.

Injecting the Registry

The registry is auto-configured and available for injection:

@Service
public class RuleExecutionService {

    private final RuleRegistry registry;

    @Autowired
    public RuleExecutionService(RuleRegistry registry) {
        this.registry = registry;
    }

    public void executeByName(String ruleName) {
        Rule rule = registry.get(ruleName);
        rule.run();
    }
}

Looking Up Rules

You can retrieve a rule by its name (the bean name assigned during scanning):

// Get a rule by name
Rule rule = registry.get("CreditCheckRule");

// Get with a specific type
Rule rule = registry.get("CreditCheckRule", Rule.class);

Listing All Rules

// All registered rules
List<Rule> rules = registry.getRules();

// All registered rulesets
List<RuleSet> ruleSets = registry.getRuleSets();

// Check if a name is already registered
boolean exists = registry.isNameInUse("CreditCheckRule");

// Total count of runnable beans
int count = registry.getCount();

Registry API Reference

Context Shutdown

Like SpringObjectFactory, the registry listens for ContextClosedEvent and releases its reference to the ListableBeanFactory. Any call to the registry after shutdown throws an UnrulyException with a clear message: "Application Context is closed."
