}

3. 业务工具集成

@Component
public class CustomerServiceTools {private final OrderService orderService;private final UserService userService;private final RefundService refundService;private final LogisticsService logisticsService;/*** 查询订单信息*/@ToolFunction(name = "query_order",description = "查询用户的订单信息，包括订单状态、商品详情、物流信息等")public OrderInfo queryOrder(OrderQueryRequest request, ToolContext context) {String userId = (String) context.get("user_id");// 权限检查if (!hasOrderAccess(userId, request.getOrderId())) {throw new ToolExecutionException("无权访问该订单信息");}try {Order order = orderService.findById(request.getOrderId());if (order == null) {return OrderInfo.notFound(request.getOrderId());}// 获取物流信息LogisticsInfo logistics = logisticsService.getLogisticsInfo(order.getLogisticsNumber());return OrderInfo.builder().orderId(order.getId()).status(order.getStatus()).items(order.getItems()).totalAmount(order.getTotalAmount()).createTime(order.getCreateTime()).logistics(logistics).build();} catch (Exception e) {throw new ToolExecutionException("查询订单失败", e);}}/*** 处理退款申请*/@ToolFunction(name = "process_refund",description = "处理用户的退款申请，需要验证订单状态和退款条件")public RefundResult processRefund(RefundRequest request, ToolContext context) {String userId = (String) context.get("user_id");try {// 验证订单Order order = orderService.findById(request.getOrderId());if (order == null || !order.getUserId().equals(userId)) {return RefundResult.failed("订单不存在或无权操作");}// 检查退款条件RefundEligibility eligibility = refundService.checkEligibility(order);if (!eligibility.isEligible()) {return RefundResult.failed(eligibility.getReason());}// 创建退款申请RefundApplication application = RefundApplication.builder().orderId(request.getOrderId()).userId(userId).amount(request.getAmount()).reason(request.getReason()).type(request.getType()).build();RefundApplication savedApplication = refundService.createApplication(application);// 自动审核（小额退款）if (request.getAmount().compareTo(new BigDecimal("100")) <= 0) {refundService.autoApprove(savedApplication.getId());return RefundResult.success("退款申请已自动通过，预计3-5个工作日到账");} else {return RefundResult.pending("退款申请已提交，将在24小时内审核");}} catch (Exception e) {logger.error("Refund processing failed", e);return RefundResult.failed("退款处理失败，请联系人工客服");}}/*** 更新用户信息*/@ToolFunction(name = "update_user_profile",description = "更新用户的个人信息，如地址、电话等")public UpdateResult updateUserProfile(UserUpdateRequest request, ToolContext context) {String userId = (String) context.get("user_id");try {// 数据验证validateUserUpdateRequest(request);// 更新用户信息User user = userService.findById(userId);if (user == null) {return UpdateResult.failed("用户不存在");}// 应用更新if (request.getPhone() != null) {user.setPhone(request.getPhone());}if (request.getAddress() != null) {user.setAddress(request.getAddress());}if (request.getEmail() != null) {user.setEmail(request.getEmail());}userService.save(user);return UpdateResult.success("用户信息更新成功");} catch (ValidationException e) {return UpdateResult.failed("输入信息格式错误：" + e.getMessage());} catch (Exception e) {logger.error("User profile update failed", e);return UpdateResult.failed("更新失败，请稍后重试");}}/*** 智能推荐商品*/@ToolFunction(name = "recommend_products",description = "基于用户历史和偏好推荐相关商品")public RecommendationResult recommendProducts(RecommendationRequest request, ToolContext context) {String userId = (String) context.get("user_id");try {// 获取用户画像UserProfile profile = userService.getUserProfile(userId);// 获取推荐商品List<Product> recommendations = recommendationService.getRecommendations(RecommendationQuery.builder().userId(userId).category(request.getCategory()).priceRange(request.getPriceRange()).limit(request.getLimit()).userProfile(profile).build());return RecommendationResult.builder().products(recommendations).reason("基于您的购买历史和偏好推荐").confidence(0.85).build();} catch (Exception e) {logger.error("Product recommendation failed", e);return RecommendationResult.empty("暂时无法提供推荐");}}
}

安全与合规实现

1. 内容安全防护

@Component
public class ContentSecurityService {private final SensitiveWordDetector sensitiveWordDetector;private final PersonalInfoDetector personalInfoDetector;private final ToxicityClassifier toxicityClassifier;/*** 输入内容安全检查*/public SecurityCheckResult checkInputSecurity(String content, String userId) {SecurityCheckResult.Builder resultBuilder = SecurityCheckResult.builder().content(content).userId(userId);// 1. 敏感词检测SensitiveWordResult sensitiveResult = sensitiveWordDetector.detect(content);if (sensitiveResult.hasSensitiveWords()) {return resultBuilder.safe(false).reason("包含敏感词汇").sensitiveWords(sensitiveResult.getWords()).build();}// 2. 个人信息检测PersonalInfoResult personalInfoResult = personalInfoDetector.detect(content);if (personalInfoResult.hasPersonalInfo()) {// 记录但不阻止，用于脱敏处理resultBuilder.personalInfo(personalInfoResult.getInfoTypes());}// 3. 毒性内容检测ToxicityResult toxicityResult = toxicityClassifier.classify(content);if (toxicityResult.getToxicityScore() > 0.7) {return resultBuilder.safe(false).reason("内容可能包含不当信息").toxicityScore(toxicityResult.getToxicityScore()).build();}return resultBuilder.safe(true).build();}/*** 输出内容安全处理*/public String sanitizeOutput(String content) {String sanitized = content;// 1. 个人信息脱敏sanitized = personalInfoDetector.mask(sanitized);// 2. 敏感信息过滤sanitized = sensitiveWordDetector.filter(sanitized);// 3. 格式化处理sanitized = formatOutput(sanitized);return sanitized;}/*** 用户行为风险评估*/public RiskAssessmentResult assessUserRisk(String userId, String content) {// 获取用户历史行为UserBehaviorHistory history = getUserBehaviorHistory(userId);// 计算风险分数double riskScore = calculateRiskScore(history, content);RiskLevel riskLevel;if (riskScore < 0.3) {riskLevel = RiskLevel.LOW;} else if (riskScore < 0.7) {riskLevel = RiskLevel.MEDIUM;} else {riskLevel = RiskLevel.HIGH;}return RiskAssessmentResult.builder().userId(userId).riskScore(riskScore).riskLevel(riskLevel).factors(analyzeRiskFactors(history, content)).recommendations(generateSecurityRecommendations(riskLevel)).build();}
}

2. 数据隐私保护

@Component
public class PrivacyProtectionService {private final EncryptionService encryptionService;private final AuditLogService auditLogService;/*** 敏感数据加密存储*/public void storeSensitiveData(String userId, String data, DataType dataType) {try {// 加密数据String encryptedData = encryptionService.encrypt(data);// 存储加密数据SensitiveDataRecord record = SensitiveDataRecord.builder().userId(userId).encryptedData(encryptedData).dataType(dataType).createdAt(Instant.now()).build();sensitiveDataRepository.save(record);// 记录审计日志auditLogService.logDataAccess(AuditEvent.builder().userId(userId).action("STORE_SENSITIVE_DATA").dataType(dataType.name()).timestamp(Instant.now()).build());} catch (Exception e) {logger.error("Failed to store sensitive data", e);throw new PrivacyProtectionException("数据存储失败", e);}}/*** 用户数据删除（GDPR合规）*/@Transactionalpublic void deleteUserData(String userId, DataDeletionRequest request) {try {// 验证删除权限if (!hasDataDeletionPermission(userId, request)) {throw new UnauthorizedException("无权删除数据");}// 删除各类数据if (request.isDeleteConversations()) {conversationRepository.deleteByUserId(userId);}if (request.isDeleteProfile()) {userProfileRepository.deleteByUserId(userId);}if (request.isDeleteSensitiveData()) {sensitiveDataRepository.deleteByUserId(userId);}// 记录删除操作auditLogService.logDataDeletion(AuditEvent.builder().userId(userId).action("DELETE_USER_DATA").details(request.toString()).timestamp(Instant.now()).build());} catch (Exception e) {logger.error("User data deletion failed", e);throw new PrivacyProtectionException("数据删除失败", e);}}/*** 数据访问日志记录*/@EventListenerpublic void handleDataAccessEvent(DataAccessEvent event) {auditLogService.logDataAccess(AuditEvent.builder().userId(event.getUserId()).action("DATA_ACCESS").resourceType(event.getResourceType()).resourceId(event.getResourceId()).accessType(event.getAccessType()).ipAddress(event.getIpAddress()).userAgent(event.getUserAgent()).timestamp(event.getTimestamp()).build());}
}

性能优化策略

1. 缓存策略

@Configuration
@EnableCaching
public class CacheConfiguration {@Beanpublic CacheManager cacheManager() {CaffeineCacheManager cacheManager = new CaffeineCacheManager();// 对话缓存 - 短期缓存cacheManager.registerCustomCache("conversations",Caffeine.newBuilder().maximumSize(10000).expireAfterWrite(Duration.ofMinutes(30)).recordStats().build());// 知识检索缓存 - 中期缓存cacheManager.registerCustomCache("knowledge-search",Caffeine.newBuilder().maximumSize(5000).expireAfterWrite(Duration.ofHours(2)).recordStats().build());// 用户上下文缓存 - 长期缓存cacheManager.registerCustomCache("user-context",Caffeine.newBuilder().maximumSize(50000).expireAfterWrite(Duration.ofHours(24)).recordStats().build());return cacheManager;}@Beanpublic CacheMetricsRegistrar cacheMetricsRegistrar(MeterRegistry meterRegistry) {return new CacheMetricsRegistrar(meterRegistry);}
}@Service
public class CachedKnowledgeService {@Cacheable(value = "knowledge-search", key = "#query + '_' + #topK")public List<Document> searchKnowledge(String query, int topK) {return vectorStore.similaritySearch(query, topK);}@Cacheable(value = "user-context", key = "#userId")public UserContext getUserContext(String userId) {return userContextService.loadUserContext(userId);}@CacheEvict(value = "user-context", key = "#userId")public void invalidateUserContext(String userId) {// 缓存失效}
}

2. 异步处理

@Configuration
@EnableAsync
public class AsyncConfiguration {@Bean(name = "chatTaskExecutor")public TaskExecutor chatTaskExecutor() {ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();executor.setCorePoolSize(10);executor.setMaxPoolSize(50);executor.setQueueCapacity(200);executor.setThreadNamePrefix("chat-");executor.setRejectedExecutionHandler(new ThreadPoolExecutor.CallerRunsPolicy());executor.initialize();return executor;}@Bean(name = "knowledgeTaskExecutor")public TaskExecutor knowledgeTaskExecutor() {ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();executor.setCorePoolSize(5);executor.setMaxPoolSize(20);executor.setQueueCapacity(100);executor.setThreadNamePrefix("knowledge-");executor.initialize();return executor;}
}@Service
public class AsyncChatService {@Async("chatTaskExecutor")public CompletableFuture<String> processMessageAsync(String message, String userId) {// 异步处理消息String response = chatClient.prompt(message).call().content();// 异步保存对话历史saveConversationAsync(userId, message, response);return CompletableFuture.completedFuture(response);}@Async("knowledgeTaskExecutor")public CompletableFuture<Void> updateKnowledgeAsync(List<Document> documents) {// 异步更新知识库vectorStore.add(documents);return CompletableFuture.completedFuture(null);}
}

3. 连接池优化

@Configuration
public class HttpClientConfiguration {@Beanpublic RestClient restClient() {return RestClient.builder().requestFactory(clientHttpRequestFactory()).build();}@Beanpublic ClientHttpRequestFactory clientHttpRequestFactory() {HttpComponentsClientHttpRequestFactory factory = new HttpComponentsClientHttpRequestFactory();// 连接池配置PoolingHttpClientConnectionManager connectionManager = new PoolingHttpClientConnectionManager();connectionManager.setMaxTotal(200);connectionManager.setDefaultMaxPerRoute(50);// HTTP客户端配置CloseableHttpClient httpClient = HttpClients.custom().setConnectionManager(connectionManager).setDefaultRequestConfig(RequestConfig.custom().setConnectTimeout(5000).setSocketTimeout(30000).build()).build();factory.setHttpClient(httpClient);return factory;}
}

监控与运维

1. 健康检查

@Component
public class AiHealthIndicator implements HealthIndicator {private final ChatModel chatModel;private final VectorStore vectorStore;private final MeterRegistry meterRegistry;@Overridepublic Health health() {Health.Builder builder = Health.up();try {// 检查AI模型连接checkChatModel(builder);// 检查向量数据库checkVectorStore(builder);// 检查系统指标checkSystemMetrics(builder);} catch (Exception e) {return Health.down().withDetail("error", e.getMessage()).build();}return builder.build();}private void checkChatModel(Health.Builder builder) {try {long startTime = System.currentTimeMillis();String response = chatModel.call(new Prompt("Health check")).getResult().getOutput().getContent();long responseTime = System.currentTimeMillis() - startTime;builder.withDetail("chatModel", Map.of("status", "UP","responseTime", responseTime + "ms","lastCheck", Instant.now()));} catch (Exception e) {builder.withDetail("chatModel", Map.of("status", "DOWN","error", e.getMessage()));}}private void checkVectorStore(Health.Builder builder) {try {List<Document> results = vectorStore.similaritySearch("health check", 1);builder.withDetail("vectorStore", Map.of("status", "UP","documentCount", results.size(),"lastCheck", Instant.now()));} catch (Exception e) {builder.withDetail("vectorStore", Map.of("status", "DOWN","error", e.getMessage()));}}
}

2. 自定义指标

@Component
public class BusinessMetrics {private final Counter conversationCounter;private final Timer responseTimer;private final Gauge activeUsersGauge;private final DistributionSummary satisfactionScore;public BusinessMetrics(MeterRegistry meterRegistry) {this.conversationCounter = Counter.builder("business.conversations.total").description("Total number of conversations").register(meterRegistry);this.responseTimer = Timer.builder("business.response.time").description("AI response time").register(meterRegistry);this.activeUsersGauge = Gauge.builder("business.users.active").description("Number of active users").register(meterRegistry, this, BusinessMetrics::getActiveUserCount);this.satisfactionScore = DistributionSummary.builder("business.satisfaction.score").description("User satisfaction scores").register(meterRegistry);}public void recordConversation(String userId, String channel) {conversationCounter.increment(Tags.of("user_type", getUserType(userId),"channel", channel));}public void recordResponseTime(Duration duration, String model) {responseTimer.record(duration, Tags.of("model", model));}public void recordSatisfactionScore(double score) {satisfactionScore.record(score);}private double getActiveUserCount() {// 实现活跃用户统计逻辑return activeUserService.getActiveUserCount();}
}
