</dependencies>

2. 配置参数

yaml 复制代码
# application.yml
tongyi:
  qianwen:
    api-key: your_api_key_here
    endpoint: https://dashscope.aliyuncs.com/api/v1/services/aigc/text-generation/generation
    model: qwen-turbo  # 可选 qwen-plus, qwen-max
    timeout: 5000
    max-tokens: 1500
    temperature: 0.7

三、核心服务实现

1. 请求封装类

java 复制代码
@Data
@Builder
public class QianwenRequest {
    private String model;
    private Input input;
    private Parameters parameters;
    
    @Data
    @Builder
    public static class Input {
        private List<Message> messages;
    }
    
    @Data
    @Builder
    public static class Message {
        private String role;  // system/user/assistant
        private String content;
    }
    
    @Data
    @Builder
    public static class Parameters {
        private String result_format = "text";
        private Float temperature;
        private Integer max_tokens;
    }
}

2. 响应处理类

java 复制代码
@Data
public class QianwenResponse {
    private Output output;
    private Usage usage;
    
    @Data
    public static class Output {
        private String text;
    }
    
    @Data
    public static class Usage {
        private Integer total_tokens;
    }
}

3. 服务层实现

java 复制代码
@Service
@Slf4j
public class QianwenService {
    
    @Value("${tongyi.qianwen.api-key}")
    private String apiKey;
    
    @Value("${tongyi.qianwen.endpoint}")
    private String endpoint;
    
    @Value("${tongyi.qianwen.model}")
    private String model;
    
    @Value("${tongyi.qianwen.temperature}")
    private Float temperature;
    
    @Value("${tongyi.qianwen.max-tokens}")
    private Integer maxTokens;
    
    private final WebClient webClient;
    
    public QianwenService(WebClient.Builder webClientBuilder) {
        this.webClient = webClientBuilder.build();
    }
    
    public Mono<String> generateText(String prompt) {
        QianwenRequest request = buildRequest(prompt);
        
        return webClient.post()
                .uri(endpoint)
                .header("Authorization", "Bearer " + apiKey)
                .header("Content-Type", "application/json")
                .header("X-DashScope-SSE", "enable") // 启用流式响应
                .bodyValue(JSON.toJSONString(request))
                .retrieve()
                .bodyToMono(String.class)
                .flatMap(this::parseResponse)
                .timeout(Duration.ofMillis(5000))
                .onErrorResume(e -> {
                    log.error("通义千问API调用失败", e);
                    return Mono.just("服务暂时不可用,请稍后重试");
                });
    }
    
    private QianwenRequest buildRequest(String prompt) {
        return QianwenRequest.builder()
                .model(model)
                .input(QianwenRequest.Input.builder()
                        .messages(Collections.singletonList(
                                QianwenRequest.Message.builder()
                                        .role("user")
                                        .content(prompt)
                                        .build()))
                        .build())
                .parameters(QianwenRequest.Parameters.builder()
                        .temperature(temperature)
                        .max_tokens(maxTokens)
                        .build())
                .build();
    }
    
    private Mono<String> parseResponse(String responseBody) {
        try {
            QianwenResponse response = JSON.parseObject(responseBody, QianwenResponse.class);
            return Mono.just(response.getOutput().getText());
        } catch (Exception e) {
            return Mono.error(new RuntimeException("响应解析失败"));
        }
    }
}

四、高级功能扩展

1. 流式响应处理

java 复制代码
public Flux<String> streamGenerateText(String prompt) {
    QianwenRequest request = buildRequest(prompt);
    
    return webClient.post()
            .uri(endpoint)
            .header("Authorization", "Bearer " + apiKey)
            .header("Content-Type", "application/json")
            .header("X-DashScope-SSE", "enable")
            .bodyValue(JSON.toJSONString(request))
            .retrieve()
            .bodyToFlux(DataBuffer.class)
            .map(dataBuffer -> {
                byte[] bytes = new byte[dataBuffer.readableByteCount()];
                dataBuffer.read(bytes);
                DataBufferUtils.release(dataBuffer);
                return new String(bytes, StandardCharsets.UTF_8);
            })
            .filter(chunk -> chunk.contains("data:"))
            .map(chunk -> {
                String json = chunk.substring(5).trim();
                return JSON.parseObject(json, QianwenResponse.class);
            })
            .map(response -> response.getOutput().getText())
            .onErrorResume(e -> Flux.just("流式响应出错"));
}

2. 国产加密传输

java 复制代码
@Configuration
public class SecurityConfig {
    
    @Bean
    public Sms4 sms4Cipher(@Value("${tongyi.encrypt.key}") String key) {
        return new Sms4(key.getBytes());
    }
}

@Component
public class SecureQianwenService {
    
    private final QianwenService qianwenService;
    private final Sms4 sms4;
    
    public SecureQianwenService(QianwenService qianwenService, Sms4 sms4) {
        this.qianwenService = qianwenService;
        this.sms4 = sms4;
    }
    
    public Mono<String> secureGenerate(String prompt) {
        // 加密输入
        byte[] encrypted = sms4.encryptECB(prompt.getBytes());
        String base64Prompt = Base64.getEncoder().encodeToString(encrypted);
        
        return qianwenService.generateText(base64Prompt)
                .map(response -> {
                    // 解密输出
                    byte[] decoded = Base64.getDecoder().decode(response);
                    return new String(sms4.decryptECB(decoded));
                });
    }
}

五、性能优化策略

1. 请求批处理

java 复制代码
public Mono<List<String>> batchGenerate(List<String> prompts) {
    List<Mono<String>> monos = prompts.stream()
            .map(this::generateText)
            .collect(Collectors.toList());
    
    return Flux.merge(monos).collectList();
}

2. 本地缓存策略

java 复制代码
@Cacheable(value = "qianwenCache", key = "#prompt.hashCode()")
public Mono<String> cachedGenerate(String prompt) {
    return generateText(prompt);
}

3. 流量控制

java 复制代码
@Bean
public QianwenService rateLimitedQianwenService(QianwenService delegate) {
    // 每秒最多5个请求
    RateLimiter limiter = RateLimiter.create(5.0);
    
    return new QianwenService() {
        @Override
        public Mono<String> generateText(String prompt) {
            if (limiter.tryAcquire()) {
                return delegate.generateText(prompt);
            }
            return Mono.just("请求过于频繁,请稍后再试");
        }
    };
}

六、国产化适配方案

1. 麒麟/统信系统支持

dockerfile 复制代码
# Dockerfile
FROM openanolis/anolisos:8.8-x86_64

# 安装国产JDK
RUN yum install -y dragonwell8-17.0.8.7.8

# 设置时区
RUN ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

# 复制应用
COPY target/qianwen-integration.jar /app.jar

# 使用国密TLS
ENV JAVA_OPTS="-Dcom.tencent.kona.ssl.debug=true -Dcom.tencent.kona.pkcs12.debug=true"

ENTRYPOINT ["java", "-jar", "/app.jar"]

2. 人大金仓数据库集成

java 复制代码
@Entity
@Table(name = "qianwen_log")
public class QianwenLog {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;
    
    @Column(name = "prompt", columnDefinition = "TEXT")
    private String prompt;
    
    @Column(name = "response", columnDefinition = "TEXT")
    private String response;
    
    @Column(name = "created_at")
    private LocalDateTime createdAt;
}

@Repository
public interface QianwenLogRepository extends JpaRepository<QianwenLog, Long> {
}

七、监控与告警

1. Prometheus 监控配置

java 复制代码
@Bean
MeterRegistryCustomizer<MeterRegistry> metrics() {
    return registry -> {
        Counter.builder("qianwen.requests")
            .tag("model", model)
            .register(registry);
        
        Timer.builder("qianwen.latency")
            .register(registry);
    };
}

@Aspect
@Component
public class QianwenMonitorAspect {
    
    @Autowired
    private MeterRegistry meterRegistry;
    
    @Around("execution(* com.example.service.QianwenService.generateText(..))")
    public Object monitor(ProceedingJoinPoint pjp) throws Throwable {
        Counter counter = meterRegistry.counter("qianwen.requests");
        counter.increment();
        
        Timer.Sample sample = Timer.start(meterRegistry);
        try {
            return pjp.proceed();
        } finally {
            sample.stop(meterRegistry.timer("qianwen.latency"));
        }
    }
}

2. 告警规则配置

yaml 复制代码
# alert-rules.yml
groups:
- name: qianwen-alerts
  rules:
  - alert: HighErrorRate
    expr: sum(rate(qianwen_errors_total[5m])) by (model) / sum(rate(qianwen_requests_total[5m])) by (model) > 0.1
    for: 5m
    labels:
      severity: critical
    annotations:
      summary: "通义千问API错误率过高"
      description: "{{ $labels.model }} 错误率: {{ $value }}"
      
  - alert: HighLatency
    expr: histogram_quantile(0.95, sum(rate(qianwen_latency_seconds_bucket[5m])) by (le)) > 3
    for: 10m
    labels:
      severity: warning

八、完整控制器示例

java 复制代码
@RestController
@RequestMapping("/api/qianwen")
public class QianwenController {
    
    private final QianwenService qianwenService;
    
    public QianwenController(QianwenService qianwenService) {
        this.qianwenService = qianwenService;
    }
    
    @PostMapping("/generate")
    public Mono<ResponseEntity<String>> generate(@RequestBody Map<String, String> request) {
        String prompt = request.get("prompt");
        if (StringUtils.isEmpty(prompt)) {
            return Mono.just(ResponseEntity.badRequest().body("请输入有效内容"));
        }
        
        return qianwenService.generateText(prompt)
                .map(response -> ResponseEntity.ok(response))
                .onErrorReturn(ResponseEntity.status(503).body("服务暂时不可用"));
    }
    
    @GetMapping("/stream")
    public Flux<ServerSentEvent<String>> streamGenerate(@RequestParam String prompt) {
        return qianwenService.streamGenerateText(prompt)
                .map(text -> ServerSentEvent.builder(text).build())
                .onErrorResume(e -> Flux.just(
                    ServerSentEvent.builder("服务中断").build()
                ));
    }
}

九、压力测试报告
