之前做的excel文件导出都相对简单,用的都是公司自己封装的一些poi方法,导出内容都是表头+一行行的数据,但是这次需要导出的excel复杂度高了不少,自己用现有方法做比较麻烦,因此引入了Easypoi 进行实现。
之所以用Easypoi我是看中了它可以直接根据现有模板填充数据实现excel生成,而模板产品已经给出,那么接下来只需要稍微做修改就能使用,修改后的模板如图:
对照着官方文档的示例(http://easypoi.mydoc.io/#text_226078 ) 很容易就能理解模板的使用规则
注意其中的{{$fe: 是遍历listmap变量循环填充数据行,其他则是类似占位符,很好理解
//代码就纯粹只是把模板的占位符和变量对应起来
Map<String, Object> map = new HashMap<String, Object>();
map.put("code", customer.getCode());
map.put("name", customer.getName());
map.put("mobile", customer.getMobile());
map.put("membershipGrade", customer.getMembershipGrade());
map.put("zzyMembershipGrade", customer.getZzyMembershipGrade());
map.put("addressComplete", customer.getAddressComplete());
List<Map<String, String>> listMap = new ArrayList<Map<String, String>>();
map.put("maplist", listMap);
SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
for (MainOrderSubOrderFinanceResult financeResult : mainOrderSubOrderFinanceResults) {
Map<String, String> lm = new HashMap<String, String>();
lm.put("orderCode", financeResult.getOrderCode());
lm.put("payStatusDesc", financeResult.getPayStatusDesc());
lm.put("settlementTypeDesc", financeResult.getSettlementTypeDesc());
lm.put("billDate", dateFormat.format(financeResult.getBillDate()));
lm.put("totalAmount", financeResult.getTotalAmount().stripTrailingZeros().toPlainString());
lm.put("discountAmount", financeResult.getDiscountAmount().stripTrailingZeros().toPlainString());
lm.put("amount", financeResult.getAmount().stripTrailingZeros().toPlainString());
lm.put("payAmount", financeResult.getPayAmount().stripTrailingZeros().toPlainString());
lm.put("amountPaid", financeResult.getAmountPaid().stripTrailingZeros().toPlainString());
listMap.add(lm);
sumTotalAmount = sumTotalAmount.add(financeResult.getTotalAmount());
sumDiscountAmount = sumDiscountAmount.add(financeResult.getDiscountAmount());
sumAmount = sumAmount.add(financeResult.getAmount());
sumPayAmount = sumPayAmount.add(financeResult.getPayAmount());
sumAmountPaid = sumAmountPaid.add(financeResult.getAmountPaid());
}
map.put("sumTotalAmount", sumTotalAmount);
map.put("sumDiscountAmount", sumDiscountAmount);
map.put("sumAmount", sumAmount);
map.put("sumPayAmount", sumPayAmount);
map.put("sumAmountPaid", sumAmountPaid);
//生成临时模板文件
String url="";
try {
File temp = File.createTempFile("exportCreditBillResult", ".xlsx");
FileUploadHelper.inputStream2File(this.getClass().getClassLoader().getResourceAsStream("exportCreditBillResult.xlsx"),temp);
url=temp.getAbsolutePath();
temp.deleteOnExit();
} catch (IOException e) {
}
TemplateExportParams params = new TemplateExportParams(url);
Workbook workbook = ExcelExportUtil.exportExcel(params, map);
