Features | 主要功能:

  • Read metadata by class name - 按类名读取元数据
  • Read metadata from resource - 从资源读取元数据
  • Read metadata from Class object - 从 Class 对象读取元数据
  • Batch reading with filtering - 批量读取带过滤

Usage Examples | 使用示例:

ClassMetadata metadata = MetadataReader.read("com.example.MyClass");
ClassMetadata metadata = MetadataReader.read(MyClass.class);
List<ClassMetadata> all = MetadataReader.readAll("com.example");
