                .client(deepSeekClient)
                .build();
    }
}

3.2 智能对话服务实现

@RestController
@RequestMapping("/api/chat")
public class ChatController {
    private final ChatClient chatClient;
    public ChatController(ChatClient chatClient) {
        this.chatClient = chatClient;
    }
    @PostMapping
    public Mono<ChatResponse> chat(
            @RequestBody ChatRequest request,
            @RequestParam(defaultValue = "0.7") double temperature) {
        return chatClient.streamChatCompletion(
                ChatMessage.builder()
                        .role(ChatRole.USER)
                        .content(request.getMessage())
                        .build(),
                ChatOptions.builder()
                        .temperature(temperature)
                        .build())
                .last() // 获取完整响应
                .map(this::formatResponse);
    }
    private ChatResponse formatResponse(ChatCompletion chatCompletion) {
        return ChatResponse.builder()
                .reply(chatCompletion.getContent())
                .tokensUsed(chatCompletion.getUsage().getTotalTokens())
                .build();
    }
}

3.3 高级功能扩展

3.3.1 多轮对话管理

public class ConversationManager {
    private final Map<String, List<ChatMessage>> sessions = new ConcurrentHashMap<>();
    public List<ChatMessage> getMessages(String sessionId) {
        return sessions.computeIfAbsent(sessionId, k -> new ArrayList<>());
    }
    public void addMessage(String sessionId, ChatMessage message) {
        getMessages(sessionId).add(message);
    }
    public void clearSession(String sessionId) {
        sessions.remove(sessionId);
    }
}

3.3.2 模型路由策略

public class ModelRouter {
    private final Map<String, ChatClient> clients;
    public ModelRouter(List<ChatClient> chatClients) {
        this.clients = chatClients.stream()
                .collect(Collectors.toMap(
                        client -> client.getClass().getSimpleName(),
                        Function.identity()));
    }
    public ChatClient getClient(String modelName) {
        return Optional.ofNullable(clients.get(modelName))
                .orElseThrow(() -> new IllegalArgumentException("Unsupported model: " + modelName));
    }
}

四、生产级部署方案

4.1 容器化部署配置

# Dockerfile示例
FROM eclipse-temurin:17-jre-jammy
VOLUME /tmp
ARG JAR_FILE=target/*.jar
COPY ${JAR_FILE} app.jar
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]

4.2 Kubernetes部署清单

# deployment.yaml
apiVersion: apps/v1
kind: Deployment

              name: ai-credentials
              key: api-key

4.3 监控与告警配置

@Configuration
public class MetricsConfig {
    @Bean
    public MicrometerCollectorRegistry micrometerRegistry() {
        return new MicrometerCollectorRegistry(
                Metrics.globalRegistry,
                Tag.of("service", "spring-ai-service"));
    }
    @Bean
    public PrometheusMeterRegistry prometheusRegistry() {
        return new PrometheusMeterRegistry();
    }
    @Bean
    public SimpleMeterRegistry simpleMeterRegistry() {
        return new SimpleMeterRegistry();
    }
}

五、性能优化与最佳实践

5.1 响应优化策略

流式响应处理：使用WebFlux实现SSE（Server-Sent Events）

@GetMapping(value = "/stream", produces = MediaType.TEXT_EVENT_STREAM_VALUE)
public Flux<String> streamChat(
     @RequestParam String prompt,
     @RequestParam(defaultValue = "0.7") double temperature) {
 return chatClient.streamChatCompletion(
         ChatMessage.of(ChatRole.USER, prompt),
         ChatOptions.builder().temperature(temperature).build())
         .map(ChatCompletion::getContent)
         .map(content -> "data: " + content + "\n\n");
}

缓存策略：实现对话上下文缓存

@Cacheable(value = "conversationCache", key = "#sessionId")
public List<ChatMessage> getConversationHistory(String sessionId) {
 // 从数据库或缓存获取历史记录
}

5.2 错误处理机制

@ControllerAdvice
public class GlobalExceptionHandler {
    @ExceptionHandler(AiServiceException.class)
    public ResponseEntity<ErrorResponse> handleAiException(AiServiceException ex) {
        return ResponseEntity.status(ex.getStatusCode())
                .body(ErrorResponse.builder()
                        .code(ex.getErrorCode())
                        .message(ex.getMessage())
                        .timestamp(Instant.now())
                        .build());
    }
    @ExceptionHandler(RateLimitException.class)
    public ResponseEntity<ErrorResponse> handleRateLimit(RateLimitException ex) {
        return ResponseEntity.status(429)
                .header("Retry-After", "60")
                .body(ErrorResponse.builder()
                        .code("RATE_LIMIT")
                        .message("API rate limit exceeded")
                        .build());
    }
}

六、安全合规实践

6.1 数据安全措施

敏感信息过滤：实现PII（个人可识别信息）检测

public class PiiFilter {
 private static final Pattern PII_PATTERN = Pattern.compile(
         "(?i)\\b(?:\\d{3}-\\d{2}-\\d{4}|\\d{16}|\\w+@\\w+\\.\\w+)\\b");
 public static String sanitize(String input) {
     Matcher matcher = PII_PATTERN.matcher(input);
     StringBuffer sb = new StringBuffer();
     while (matcher.find()) {
         matcher.appendReplacement(sb, "[REDACTED]");
     }
     matcher.appendTail(sb);
     return sb.toString();
 }
}

审计日志：记录所有AI交互

@Aspect
@Component
public class AuditLoggingAspect {
 private static final Logger logger = LoggerFactory.getLogger("AI_AUDIT");
 @AfterReturning(
         pointcut = "execution(* com.example.controller.ChatController.*(..))",
         returning = "result")
 public void logAiInteraction(JoinPoint joinPoint, Object result) {
     AuditLog log = new AuditLog();
     log.setUserId(getAuthenticatedUserId());
     log.setOperation(joinPoint.getSignature().getName());
     log.setTimestamp(Instant.now());
     log.setResponse(objectMapper.writeValueAsString(result));
     logger.info(objectMapper.writeValueAsString(log));
 }
}

6.2 合规性检查

内容安全检测：集成第三方内容审核API

public class ContentSafetyChecker {
 private final ContentSafetyClient safetyClient;
 public ContentSafetyChecker(ContentSafetyClient safetyClient) {
     this.safetyClient = safetyClient;
 }
 public boolean isSafe(String content) {
     SafetyCheckResult result = safetyClient.check(content);
     return result.getViolations().isEmpty();
 }
}

七、扩展应用场景

7.1 智能客服系统

public class CustomerServiceBot {
    private final ChatClient chatClient;
    private final KnowledgeBase knowledgeBase;
    public Mono<String> handleQuery(String query, String userId) {
        return knowledgeBase.findRelevantDocuments(query)
                .switchIfEmpty(Mono.just(Collections.emptyList()))
                .flatMapMany(Flux::fromIterable)
                .collectList()
                .flatMap(docs -> {
                    String context = docs.stream()
                            .map(Document::getContent)
                            .collect(Collectors.joining("\n\n"));
                    return chatClient.chatCompletion(
                            ChatMessage.builder()
                                    .role(ChatRole.SYSTEM)
                                    .content("You are a customer service agent. " +
                                            "Use the following context to answer: " + context)
                                    .build(),
                            ChatMessage.of(ChatRole.USER, query));
                })
                .map(ChatCompletion::getContent);
    }
}

7.2 代码生成助手

public class CodeGenerator {
    private final ChatClient chatClient;
    public Mono<String> generateCode(String requirements, String language) {
        String prompt = String.format("""
                Generate %s code that:
                %s
                Requirements:
                - Follow best practices
                - Include comments
                - Handle edge cases
                """, language, requirements);
        return chatClient.chatCompletion(
                ChatMessage.of(ChatRole.SYSTEM, 
                        "You are an expert programmer. Generate clean, efficient code."),
                ChatMessage.of(ChatRole.USER, prompt))
                .map(ChatCompletion::getContent);
    }
}
