@Slf4j
public class UserController {
private final UserService userService;
private final FeatureFlagService flagService;
private final LDUserBuilder userBuilder;
public UserController(UserService userService, FeatureFlagService flagService, LDUserBuilder userBuilder) {
this.userService = userService;
this.flagService = flagService;
this.userBuilder = userBuilder;
}
@GetMapping("/users/{id}")
public ResponseEntity<User> getUser(@PathVariable String id, HttpServletRequest request) {
User user = userService.findById(id);
LDUser ldUser = userBuilder.fromHttpRequest(request).build();
// Check if new UI features should be shown
if (flagService.isEnabled(FeatureFlagService.NEW_UI_FEATURE, ldUser)) {
user.setUiVersion("v2");
} else {
user.setUiVersion("v1");
}
// Track that user was viewed with new UI
if ("v2".equals(user.getUiVersion())) {
flagService.trackEvent("user_viewed_v2", ldUser);
}
return ResponseEntity.ok(user);
}
@FeatureFlag(FeatureFlagService.PREMIUM_FEATURES)
@GetMapping("/users/{id}/premium")

@RequestBody PaymentRequest paymentRequest,
HttpServletRequest request) {
User user = userService.findById(id);
LDUser ldUser = userBuilder.fromUser(user)
.custom("paymentAmount", String.valueOf(paymentRequest.getAmount()))
.custom("paymentMethod", paymentRequest.getMethod())
.build();
PaymentResponse response;
// Route to different payment services based on feature flag
if (flagService.isEnabled(FeatureFlagService.PAYMENT_V2, ldUser)) {
response = userService.processPaymentV2(user, paymentRequest);
flagService.trackEvent("payment_processed_v2", ldUser, 
JsonUtils.toJson(paymentRequest), (double) paymentRequest.getAmount());
} else {
response = userService.processPaymentV1(user, paymentRequest);
flagService.trackEvent("payment_processed_v1", ldUser, 
JsonUtils.toJson(paymentRequest), (double) paymentRequest.getAmount());
}
return ResponseEntity.ok(response);
}
@GetMapping("/features")
public ResponseEntity<Map<String, Object>> getFeaturesForUser(HttpServletRequest request) {
LDUser user = userBuilder.fromHttpRequest(request).build();
FeatureFlagsState flagsState = flagService.getAllFlagsState(user);
Map<String, Object> features = new HashMap<>();
if (flagsState != null) {
features.put("flags", flagsState.toValuesMap());
features.put("userKey", user.getKey());
}
return ResponseEntity.ok(features);
}
}
2. Service Layer Usage
@Service
@Slf4j
public class NotificationService {
private final FeatureFlagService flagService;
private final EmailService emailService;
private final PushNotificationService pushService;
public NotificationService(FeatureFlagService flagService, EmailService emailService, 
PushNotificationService pushService) {
this.flagService = flagService;
this.emailService = emailService;
this.pushService = pushService;
}
public void sendWelcomeNotification(User user) {
LDUser ldUser = new LDUser.Builder(user.getId())
.email(user.getEmail())
.custom("tier", user.getTier())
.custom("country", user.getCountry())
.build();
// Use different notification templates based on feature flag
String templateKey = flagService.getStringVariation("welcome-template", ldUser, "default");
NotificationTemplate template = getTemplate(templateKey);
emailService.sendWelcomeEmail(user, template);
// Track which template was used
flagService.trackEvent("welcome_notification_sent", ldUser, 
JsonUtils.toJson(Map.of("template", templateKey)), null);
}
@FeatureFlag("push-notifications")
public void sendPushNotification(User user, String message) {
LDUser ldUser = new LDUser.Builder(user.getId())
.custom("notificationType", "push")
.build();
pushService.sendNotification(user, message);
flagService.trackEvent("push_notification_sent", ldUser);
}
public void sendBatchNotifications(List<User> users, String message) {
// Use percentage rollout for batch operations
int enabledCount = 0;
for (User user : users) {
LDUser ldUser = new LDUser.Builder(user.getId()).build();
if (flagService.isEnabled("batch-notifications", ldUser)) {
sendPushNotification(user, message);
enabledCount++;
}
}
log.info("Sent batch notifications to {} out of {} users", enabledCount, users.size());
}
}
3. Thymeleaf Integration
@Component
public class ThymeleafFeatureFlagProcessor {
private final FeatureFlagService flagService;
private final LDUserBuilder userBuilder;
public ThymeleafFeatureFlagProcessor(FeatureFlagService flagService, LDUserBuilder userBuilder) {
this.flagService = flagService;
this.userBuilder = userBuilder;
}
public boolean isEnabled(String flagKey, HttpServletRequest request) {
LDUser user = userBuilder.fromHttpRequest(request).build();
return flagService.isEnabled(flagKey, user);
}
}
@ControllerAdvice
public class FeatureFlagControllerAdvice {
private final ThymeleafFeatureFlagProcessor flagProcessor;
public FeatureFlagControllerAdvice(ThymeleafFeatureFlagProcessor flagProcessor) {
this.flagProcessor = flagProcessor;
}
@ModelAttribute("featureFlags")
public ThymeleafFeatureFlagProcessor featureFlags() {
return flagProcessor;
}
}
<!-- In Thymeleaf template -->
<div th:if="${@featureFlags.isEnabled('new-ui-feature', request)}">
<div class="new-ui-component">
<!-- New UI content -->
</div>
</div>
<div th:unless="${@featureFlags.isEnabled('new-ui-feature', request)}">
<div class="old-ui-component">
<!-- Old UI content -->
</div>
</div>

Testing and Monitoring

1. Test Configuration
@TestConfiguration
public class LaunchDarklyTestConfig {
@Bean
@Primary
public LDClient testLDClient() {
// Use in-memory test client
LDConfig config = new LDConfig.Builder()
.dataSource(Components.externalUpdatesOnly())
.events(Components.noEvents())
.build();
return new LDClient("test-sdk-key", config);
}
@Bean
@Primary
public FeatureFlagService testFeatureFlagService(LDClient ldClient, LDUserBuilder userBuilder) {
return new FeatureFlagService(ldClient, userBuilder);
}
}
@SpringBootTest
@TestPropertySource(properties = "launchdarkly.offline=true")
class FeatureFlagServiceTest {
@Autowired
private FeatureFlagService flagService;
@Autowired
private LDClient ldClient;
@Test
void testFeatureFlagEvaluation() {
// Given
LDUser user = new LDUser.Builder("test-user").build();
// When/Then - test with offline client
assertThat(flagService.isEnabled("test-flag", user)).isFalse();
}
}
2. Health Check
@Component
public class LaunchDarklyHealthIndicator implements HealthIndicator {
private final LDClient ldClient;
public LaunchDarklyHealthIndicator(LDClient ldClient) {
this.ldClient = ldClient;
}
@Override
public Health health() {
try {
boolean initialized = ldClient.isInitialized();
boolean valid = ldClient.isOffline() || initialized;
if (valid) {
return Health.up()
.withDetail("initialized", initialized)
.withDetail("offline", ldClient.isOffline())
.build();
} else {
return Health.down()
.withDetail("error", "LaunchDarkly client not initialized")
.build();
}
} catch (Exception e) {
return Health.down(e).build();
}
}
}
3. Metrics and Monitoring
@Component
public class LaunchDarklyMetrics {
private final FeatureFlagService flagService;
private final MeterRegistry meterRegistry;
private final Counter flagEvaluationCounter;
private final Timer flagEvaluationTimer;
public LaunchDarklyMetrics(FeatureFlagService flagService, MeterRegistry meterRegistry) {
this.flagService = flagService;
this.meterRegistry = meterRegistry;
this.flagEvaluationCounter = Counter.builder("launchdarkly.flag.evaluations")
.description("Number of feature flag evaluations")
.register(meterRegistry);
this.flagEvaluationTimer = Timer.builder("launchdarkly.flag.evaluation.time")
.description("Time taken for feature flag evaluation")
.register(meterRegistry);
}
public boolean trackFlagEvaluation(String flagKey, LDUser user, Supplier<Boolean> evaluation) {
return flagEvaluationTimer.record(() -> {
boolean result = evaluation.get();
flagEvaluationCounter.increment();
// Tag with flag key and result
meterRegistry.counter("launchdarkly.flag.evaluations.result",
"flag", flagKey,
"result", String.valueOf(result)
).increment();
return result;
});
}
}

Best Practices

  1. Flag Key Management: Use constants for flag keys to avoid typos
  2. Fallback Strategies: Always provide safe fallbacks for flag evaluations
  3. User Context: Build rich user contexts for targeted rollouts
  4. Cleanup: Remove flags once they're fully rolled out
  5. Monitoring: Track flag evaluations and their business impact
  6. Testing: Test both enabled and disabled flag states
  7. Documentation: Document flag purpose, rollout plan, and cleanup criteria

This comprehensive LaunchDarkly Java SDK integration provides a robust foundation for feature flag management, enabling safe deployments, gradual rollouts, and data-driven feature decisions.
