Export "Travel Expense Reimbursement Detail" to Excel with Java (Formula & Calculated Reports)

JQuick-ExcelFormula & Calculated Reports

Formula & Calculated ReportsScene 0030

After a business trip, employees register transportation, accommodation and allowance per itinerary leg, computing Subtotal = Transportation + Accommodation + Allowance per row, with the last row summarizing each expense item and the total reimbursement. Implemented declaratively in pure XML — no Java business code required.

Travel Expense Reimbursement Detail — Formula & Calculated Reports
Full screenshot of the exported xlsx

About this demo

This demo exports the "Travel Expense Reimbursement Detail" workbook: 1 data sheet(s); MAPPING over 8 columns (出差人, 出差事由, 出发日期, 返回日期, 交通费, 住宿费, 补贴, 小计), 12 formula(s), 1 style rule(s). On the Java side it builds 6 data rows and calls exportTravelExpense() 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 (75 lines, runnable as-is)
  • The complete XML config (29 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("tropicalTeal", rows, os);
JQuickFactory factory = new JQuickXmlFactory(parser, XML);
Formulas0030TravelExpenseDetailService service = factory.createApi(Formulas0030TravelExpenseDetailService.class);

XML config · 0030_formulas_travel-expense-detail.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.
