Excel annotation mapping¶
Excel annotation mapping is a technique used to define the relationship between Java object fields and Excel columns programmatically, typically within the EasyExcel framework.^[600-developer__java__3-party__easyExcel.md]
This method employs Java annotations—specifically classes annotated with ExcelPropertyIndexModel—to explicitly specify which data fields correspond to which column indices in an Excel spreadsheet.^[600-developer__java__3-party__easyExcel.md] By using a model-based approach, developers can write data to sheets using writer.write(getData(), sheet1) without manually managing column coordinates, relying instead on the mapping logic defined in the model class.^[600-developer__java__3-party__easyExcel.md]
This feature facilitates a simpler form of Excel generation and reading where the mapping configuration is embedded directly within the data structure code.^[600-developer__java__3-party__easyExcel.md]
