Python模型服务封装这是整个系统的核心。我们需要创建一个Python服务专门负责调用Qwen-Image-Edit-F2P模型。4.1 基础模型加载先写一个模型加载的类确保模型只加载一次# model_service.py import torch from diffusers import QwenImageEditPlusPipeline from PIL import Image import base64 import io import logging import time class QwenImageService: def __init__(self, model_pathQwen/Qwen-Image-Edit-2509, lora_pathmodels/loras/edit_0928_lora_step40000.safetensors): self.logger logging.getLogger(__name__) self.device cuda if torch.cuda.is_available() else cpu self.model_path model_path self.lora_path lora_path self.logger.info(f正在加载模型到设备: {self.device}) start_time time.time() # 加载基础模型 self.pipeline QwenImageEditPlusPipeline.from_pretrained( model_path, torch_dtypetorch.bfloat16 if self.device cuda else torch.float32 ) # 加载LoRA权重 if lora_path: self.pipeline.load_lora_weights(lora_path) # 移动到GPU self.pipeline.to(self.device) # 禁用进度条显示 self.pipeline.set_progress_bar_config(disableTrue) load_time time.time() - start_time self.logger.info(f模型加载完成耗时: {load_time:.2f}秒) def generate_image(self, face_image_base64, prompt, negative_prompt, width1024, height1024, num_inference_steps40): 生成图片的核心方法 Args: face_image_base64: 人脸图片的base64编码 prompt: 生成描述 negative_prompt: 负面提示词 width: 图片宽度 height: 图片高度 num_inference_steps: 推理步数 Returns: base64编码的生成图片 try: # 解码base64图片 image_data base64.b64decode(face_image_base64) face_image Image.open(io.BytesIO(image_data)).convert(RGB) # 确保图片是人脸裁剪后的 # 这里可以添加人脸检测和裁剪逻辑 face_image self._crop_face(face_image) # 设置生成参数 generator torch.Generator(deviceself.device).manual_seed(int(time.time())) # 调用模型生成 with torch.inference_mode(): output self.pipeline( image[face_image], promptprompt, negative_promptnegative_prompt, widthwidth, heightheight, num_inference_stepsnum_inference_steps, guidance_scale1.0, true_cfg_scale4.0, generatorgenerator, num_images_per_prompt1 ) # 获取生成的图片 generated_image output.images[0] # 转换为base64 buffered io.BytesIO() generated_image.save(buffered, formatPNG) img_str base64.b64encode(buffered.getvalue()).decode() return { success: True, image_base64: img_str, message: 生成成功 } except Exception as e: self.logger.error(f图片生成失败: {str(e)}) return { success: False, image_base64: , message: f生成失败: {str(e)} } def _crop_face(self, image): 简单的人脸裁剪实际项目中应该用专业的人脸检测库 这里假设输入已经是裁剪好的人脸图片 # 实际项目中可以用face_recognition或dlib进行人脸检测和裁剪 # 这里为了简单直接返回原图或中心裁剪 width, height image.size min_dim min(width, height) left (width - min_dim) // 2 top (height - min_dim) // 2 right left min_dim bottom top min_dim return image.crop((left, top, right, bottom))4.2 FastAPI服务封装用FastAPI把模型服务包装成HTTP接口# app.py from fastapi import FastAPI, HTTPException from fastapi.middleware.cors import CORSMiddleware from pydantic import BaseModel import uvicorn import logging from model_service import QwenImageService # 配置日志 logging.basicConfig(levellogging.INFO) logger logging.getLogger(__name__) # 创建FastAPI应用 app FastAPI(titleQwen Image Generation Service) # 添加CORS中间件 app.add_middleware( CORSMiddleware, allow_origins[*], allow_credentialsTrue, allow_methods[*], allow_headers[*], ) # 定义请求模型 class GenerateRequest(BaseModel): face_image_base64: str prompt: str negative_prompt: str width: int 1024 height: int 1024 num_inference_steps: int 40 # 全局模型服务实例 model_service None app.on_event(startup) async def startup_event(): 启动时加载模型 global model_service try: model_service QwenImageService() logger.info(模型服务启动成功) except Exception as e: logger.error(f模型服务启动失败: {e}) raise app.get(/health) async def health_check(): 健康检查接口 return {status: healthy, model_loaded: model_service is not None} app.post(/generate) async def generate_image(request: GenerateRequest): 生成图片接口 if model_service is None: raise HTTPException(status_code503, detail模型服务未就绪) try: result model_service.generate_image( face_image_base64request.face_image_base64, promptrequest.prompt, negative_promptrequest.negative_prompt, widthrequest.width, heightrequest.height, num_inference_stepsrequest.num_inference_steps ) if not result[success]: raise HTTPException(status_code500, detailresult[message]) return result except Exception as e: logger.error(f生成请求处理失败: {str(e)}) raise HTTPException(status_code500, detailstr(e)) if __name__ __main__: uvicorn.run(app, host0.0.0.0, port8000)这个Python服务启动后就提供了一个标准的HTTP接口SpringBoot可以通过这个接口调用模型。5.

null) { log.info(缓存命中: {}, cacheKey); cached.setMessage(从缓存返回); return cached; } } catch (Exception e) { log.warn(缓存读取失败, e); } return null; } /** * 保存结果到缓存 */ public void saveToCache(GenerateRequest request, GenerateResponse response) { String cacheKey generateCacheKey(request); try { // 只缓存成功的请求 if (response.isSuccess()) { redisTemplate.opsForValue().set( cacheKey, response, CACHE_TTL ); log.info(结果已缓存: {}, cacheKey); } } catch (Exception e) { log.warn(缓存保存失败, e); } } }然后在业务服务中使用缓存// 在ImageGenerationService中添加缓存逻辑 public GenerateResponse generateImageSync(GenerateRequest request, String userId) { // 先检查缓存 GenerateResponse cached cacheService.getFromCache(request); if (cached ! null) { // 创建新的任务记录用于统计 createTaskRecord(UUID.randomUUID().toString(), request, userId); return cached; } // ... 原有的生成逻辑 ... // 生成成功后保存到缓存 cacheService.saveToCache(request, response); return response; }6.3 连接池和超时配置在application.yml中配置连接池# application.yml spring: datasource: url: jdbc:mysql://localhost:3306/ai_generation username: root password: password hikari: maximum-pool-size: 10 minimum-idle: 5 connection-timeout: 30000 idle-timeout: 600000 max-lifetime: 1800000 redis: host: localhost port: 6379 lettuce: pool: max-active: 20 max-idle: 10 min-idle: 5 max-wait: 1000 python: service: url: http://localhost:8000 connect-timeout: 5000 read-timeout: 300000 # 5分钟生成图片需要时间 generation: max-concurrent: 3 # 最大并发数根据GPU内存调整 cache-enabled: true preprocess-enabled: true7. 监控和日志7.1 添加监控端点Spring Boot Actuator提供了丰富的监控端点# application.yml management: endpoints: web: exposure: include: health,info,metrics,prometheus endpoint: health: show-details: always metrics: export: prometheus: enabled: true7.2 自定义健康检查添加Python服务的健康检查// PythonServiceHealthIndicator.java Component public class PythonServiceHealthIndicator implements HealthIndicator { Autowired private PythonServiceClient pythonServiceClient; Override public Health health() { boolean isHealthy pythonServiceClient.healthCheck(); if (isHealthy) { return Health.up() .withDetail(service, python-model-service) .withDetail(status, available) .build(); } else { return Health.down() .withDetail(service, python-model-service) .withDetail(status, unavailable) .withDetail(error, Python服务不可用) .build(); } } }7.3 业务指标监控使用Micrometer记录业务指标// GenerationMetrics.java Component public class GenerationMetrics { private final MeterRegistry meterRegistry; private final Counter successCounter; private final Counter failureCounter; private final Timer generationTimer; public GenerationMetrics(MeterRegistry meterRegistry) { this.meterRegistry meterRegistry; // 成功/失败计数器 this.successCounter Counter.builder(generation.requests) .tag(status, success) .description(成功生成次数) .register(meterRegistry); this.failureCounter Counter.builder(generation.requests) .tag(status, failure) .description(失败生成次数) .register(meterRegistry); // 生成耗时计时器 this.generationTimer Timer.builder(generation.duration) .description(图片生成耗时) .register(meterRegistry); } public void recordSuccess(long duration) { successCounter.increment(); generationTimer.record(duration, TimeUnit.MILLISECONDS); } public void recordFailure() { failureCounter.increment(); } /** * 获取当前并发数 */ public int getCurrentConcurrency() { Gauge concurrencyGauge meterRegistry.find(generation.concurrent).gauge(); return concurrencyGauge !
