About this demo

This demo exports the "Inventory Turnover Report" workbook: 1 data sheet(s); MAPPING over 7 columns (物料编码, 物料名称, 入库次数, 出库次数, 期末库存, 库龄(天), 周转率(次)), 12 formula(s), 1 style rule(s). On the Java side it builds 4 data rows and calls exportInventoryTurnover() once — everything else is driven by the config.

It belongs to the "Formula & Calculated Reports" group: FORMULAS — inline expressions and aggregate functions such as Quantity × Unit Price or Balance = Receivable − Received, with SUM totals on the last row.

What you can copy from this page

  • The complete Java test class (60 lines, runnable as-is)
  • The complete XML config (26 lines: mapping, formulas, styles, charts and every other rule)

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("amethyst", rows, os);
JQuickFactory factory = new JQuickXmlFactory(parser, XML);
Formulas0005InventoryTurnoverService service = factory.createApi(Formulas0005InventoryTurnoverService.class);

XML config · 0005_formulas_inventory-turnover.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.
