Export "Inventory Alert Report" to Excel with Java (Styled & Formatted Reports)

JQuick-ExcelStyled & Formatted Reports

Styled & Formatted ReportsScene 0035

Compares current inventory with safety stock per material, computing Inventory Variance = Current Inventory - Safety Stock per row, where a negative variance reaches the alert threshold, and the last row summarizes the two inventory quantity columns and gives the total variance. Implemented declaratively in pure XML — no Java business code required.

About this demo

This demo exports the "Inventory Alert Report" workbook: 1 data sheet(s); MAPPING over 7 columns (物料编码, 物料名称, 所属仓库, 当前库存, 安全库存, 库存差额, 预警状态), 10 formula(s), 1 style rule(s). On the Java side it builds 6 data rows and calls exportInventoryAlert() 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 (63 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("oceanBlue", rows, os);
JQuickFactory factory = new JQuickXmlFactory(parser, XML);
Style0035InventoryAlertReportService service = factory.createApi(Style0035InventoryAlertReportService.class);

XML config · 0035_style_inventory-alert-report.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.
