Export "Inventory Age Analysis" to Excel with Java (Styled & Formatted Reports)

JQuick-ExcelStyled & Formatted Reports

Styled & Formatted ReportsScene 0028

Layers inventory by age range, tallying the number of material types, inventory amount and amount share for each range, with a summary in the last row; the cell of the range with the longest age is marked in red to flag slow-moving inventory risk. Implemented declaratively in pure XML — no Java business code required.

About this demo

This demo exports the "Inventory Age Analysis" workbook: 1 data sheet(s); MAPPING over 5 columns (库龄区间, 物料种类数, 库存金额, 金额占比, 风险等级), 9 formula(s), 1 style rule(s). On the Java side it builds 5 data rows and calls exportInventoryAging() once — everything else is driven by the config.

It belongs to the "Styled & Formatted Reports" group: STYLE and conditional formatting: themed headers, zebra striping, highlighted total rows and threshold-based colouring of abnormal cells.

What you can copy from this page

  • The complete Java test class (59 lines, runnable as-is)
  • The complete XML config (33 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("pearl", rows, os);
JQuickFactory factory = new JQuickXmlFactory(parser, XML);
Style0028InventoryAgingAnalysisService service = factory.createApi(Style0028InventoryAgingAnalysisService.class);

XML config · 0028_style_inventory-aging-analysis.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.
