Export "Purchase Price Comparison Analysis" to Excel with Java (Formula & Calculated Reports)

JQuick-ExcelFormula & Calculated Reports

Formula & Calculated ReportsScene 0045

Compares supplier quotes with the internal benchmark price per material, computing Price Difference = Quote - Benchmark and Price Difference Rate = Price Difference / Benchmark per row, with quotes above the benchmark marked in red and the last row giving the average price and average price difference rate. Implemented declaratively in pure XML — no Java business code required.

About this demo

This demo exports the "Purchase Price Comparison Analysis" workbook: 1 data sheet(s); MAPPING over 7 columns (物料名称, 供应商, 基准价, 报价, 价差, 价差率, 价格评定), 16 formula(s), 1 style rule(s). On the Java side it builds 6 data rows and calls exportPurchasePriceCompare() 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 (63 lines, runnable as-is)
  • The complete XML config (36 lines: mapping, formulas, styles, charts and every other rule)
  • The exported xlsx file (real output, comparable with the preview above)

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("royalGold", rows, os);
JQuickFactory factory = new JQuickXmlFactory(parser, XML);
Formulas0045PurchasePriceCompareService service = factory.createApi(Formulas0045PurchasePriceCompareService.class);

XML config · 0045_formulas_purchase-price-compare.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.
