feat(image): 添加图像超分处理功能
- 新增 ImageSRStage 类实现图像超分辨率处理 - 在 AioDeviceController 中启用图像超分和增强的 Stage - 修改 ImageEnhanceStage 配置检查逻辑，增加空值和占位符检测 - 为图像处理 Pipeline 添加超分 Stage - 增加 ImageSRStage 的单元测试覆盖各种配置和执行情况 - 实现百度云图像超分 API 的调用和结果处理逻辑

/**
|
||||
* 测试说明：
|
||||
*
|
||||
* 由于 ImageSRStage 依赖外部 API (BceImageSR)，
|
||||
* 以下测试场景需要 Mock 或集成测试环境：
|
||||
*
|
||||
* 1. testExecute_Success_ValidConfig()
|
||||
* - 模拟成功的图像超分辨率调用
|
||||
* - 验证超分后文件大小变化
|
||||
* - 验证 context.updateProcessedFile() 被调用
|
||||
*
|
||||
* 2. testExecute_ApiReturnsNull_ShouldDegrade()
|
||||
* - 模拟 API 返回 null
|
||||
* - 验证返回 StageResult.degraded()
|
||||
*
|
||||
* 3. testExecute_ApiReturnsEmptyFile_ShouldDegrade()
|
||||
* - 模拟 API 返回空文件
|
||||
* - 验证返回 StageResult.degraded()
|
||||
*
|
||||
* 4. testExecute_ApiThrowsException_ShouldDegrade()
|
||||
* - 模拟 API 抛出异常
|
||||
* - 验证返回 StageResult.degraded() 而不是 failed()
|
||||
*
|
||||
* 5. testExecute_SaveFileFails_ShouldDegrade()
|
||||
* - 模拟文件保存失败
|
||||
* - 验证返回 StageResult.degraded()
|
||||
*
|
||||
* 这些测试需要使用 Mockito 或类似的 Mock 框架来模拟 BceImageSR 的行为。
|
||||
*
|
||||
* 示例（使用 Mockito）：
|
||||
*
|
||||
* @Test
|
||||
* void testExecute_Success_ValidConfig() {
|
||||
* // 创建 Mock 的 BceImageSR
|
||||
* BceImageSR mockSR = mock(BceImageSR.class);
|
||||
*
|
||||
* // 创建 Mock 的 MultipartFile
|
||||
* MultipartFile mockEnhancedImage = mock(MultipartFile.class);
|
||||
* when(mockEnhancedImage.isEmpty()).thenReturn(false);
|
||||
* when(mockEnhancedImage.getBytes()).thenReturn(new byte[]{1, 2, 3, 4, 5, 6, 7, 8});
|
||||
*
|
||||
* // 配置 Mock 行为
|
||||
* when(mockSR.enhance(anyString())).thenReturn(mockEnhancedImage);
|
||||
*
|
||||
* // 测试逻辑...
|
||||
* }
