In training assessment, scores are converted to grades (≥90 A, ≥80 B, ≥60 C, otherwise D), and the assessment date is normalized. Implemented declaratively in pure XML — no Java business code required.

About this demo

This demo exports the "Training Assessment Score Grade Sheet" workbook: 1 data sheet(s); MAPPING over 5 columns (学号, 姓名, 等级, 考核日期, 班级). On the Java side it builds 5 data rows and calls exportTrainingScoreGrade() once — everything else is driven by the config.

It belongs to the "Data Transformation" group: TRANSFORM field conversion: code-value mapping, date formatting and masking applied during export.

Minimal invocation (4 lines)

The core is these four lines: hand the rows to the parser, the parser to the factory, get a typed Service and call it. Copy them straight into your project.

// rows 由业务代码构造（List<JQuickRow>），os 为输出流，见下方完整源码
JQuickParseHandler parser = new JQuickExcelExportXmlParseFactory("amber", rows, os);
JQuickFactory factory = new JQuickXmlFactory(parser, XML);
Transform0103TrainingScoreGradeService service = factory.createApi(Transform0103TrainingScoreGradeService.class);

XML config · 0103_transform_training-score-grade.xml

Formats (FORMAT), formulas (FORMULAS) and styles (STYLE) are all declared in this XML, fully decoupled from the Java code. The full config is below — copy it as-is.
