Export "Employee Leave Request Summary" to Excel with Java (Data Validation)

JQuick-ExcelData Validation

Data ValidationScene 0061

Summarizes employee leave requests, with the last row totaling the total leave days; submitted content is rule-validated on import (employee ID / name length, department and leave-type dictionaries, leave-days value range). Implemented declaratively in pure XML — no Java business code required.

About this demo

This demo exports the "Employee Leave Request Summary" workbook: 1 data sheet(s); MAPPING over 8 columns (工号, 姓名, 部门, 请假类型, 开始日期, 结束日期, 请假天数, 审批状态), 2 formula(s), 1 style rule(s). On the Java side it builds 7 data rows and calls exportLeaveApplicationSummary() once — everything else is driven by the config.

It belongs to the "Data Validation" group: VALIDATION form validation: an input template is exported and every field is validated when it is imported back.

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("coral", rows, os);
JQuickFactory factory = new JQuickXmlFactory(parser, XML);
Validation0061LeaveApplicationSummaryService service = factory.createApi(Validation0061LeaveApplicationSummaryService.class);

XML config · 0061_validation_leave-application-summary.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.
