Easypoi word模板批量匯出
版本介紹：
spring boot1.5.6
mysql
easypoi 3.2.0
1、需求：
使用者在勾選“全選”的時候，點選批量匯出時，會根據勾選的單位名稱依次匯出在一張表中。
2、根據樣式製作一個模板
3、想要使用easypoi框架做excel/word 要匯出以下依賴
4、如果要匯出excel的話，就在實體上面新增@Excel註解（name="xxx",heigth="20"）,裡面還可以 新增excel的各個樣式（詳情可以去看easypoi API自定義）。word的話，是不需要添加註解的！
5、Controller層的結構：
Controller（service）
controller：
@RestController
@RequestMapping("/wordController")
@SuppressWarnings("all")
public class PropertyCostBillWordController {
@Autowired
private PropertyCostBillExcelService propertyCostBillExcelService;
@Autowired
private AirSecondaryOrderService airSecondaryOrderService;
@RequestMapping("/getPropertyCostBillWord")
public String getPropertyCostBillWord(HttpServletRequest request, HttpServletResponse response) {
//1，通過id list 獲取 實體物件列表
BCSLoginInfo loginInfo = BCSContext.getLoginInfo();
if (loginInfo == null) {
System.out.println("loginInfo is null");
return null;
}
String prcbIds = null;
if (!StringUtils.isEmpty(request.getParameter("prcbIds"))) {
prcbIds = request.getParameter("prcbIds");
}
//檔案下載請求頭、位元組碼、型別
response.setHeader("content-type", "application/octet-stream");
response.setContentType("application/octet-stream");
response.setCharacterEncoding("UTF-8");
//總表map
List<PropertyCostBill> propertyCostBillList = propertyCostBillExcelService.getPropertyCostBillList(prcbIds);
List<XWPFDocument> xwpfDocuments = new ArrayList<>();
try {
for (PropertyCostBill propertyCostBill : propertyCostBillList) {
DecimalFormat df = new DecimalFormat("#0.00");
double totalMoney = 0.00;
if (propertyCostBill != null) {
totalMoney = propertyCostBill.getDueAmount().doubleValue();
}
String totalMoneyCapital = CapitalUtil.moneyToChinese(totalMoney);
Map<String, Object> map = new HashMap<>();
map.put("customerName", propertyCostBill.getCustomerNameStr());
map.put("dueAmount", propertyCostBill.getDueAmountStr());
map.put("unitPrice", propertyCostBill.getUnitPrice());
map.put("totalArea", propertyCostBill.getTotalArea());
map.put("type", propertyCostBill.getTypeStr());
map.put("billBucket", propertyCostBill.getBillBucket());
map.put("totalMoney", df.format(totalMoney));
map.put("totalMoneyCapital", totalMoneyCapital);
//從resources中匯出word模板
XWPFDocument doc = WordExportUtil.exportWord07("word/property.docx", map);
xwpfDocuments.add(doc);
}
if (xwpfDocuments.size()>0) {
XWPFDocument xwpfDocument = xwpfDocuments.get(0);
for (int i = 0; i < xwpfDocuments.size(); i++) {
//每次的追加為了避免樣式和格式混亂 加上分頁符
//當是只有一條資料的時候 直接輸出
if (i == 0) {
xwpfDocument = xwpfDocuments.get(0);
continue;
} else {
//當存在多條時候
xwpfDocument = mergeWord(xwpfDocument, xwpfDocuments.get(i));
}
}
String name = "物管費繳費詳情.docx";
// 指定下載的檔名
response.setHeader("Content-Disposition", "attachment;filename=" + new String(name.getBytes("utf-8"), "ISO8859-1"));
ServletOutputStream outputStream = response.getOutputStream();
xwpfDocument.write(outputStream);
outputStream.close();
}
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
return CAjaxResult.toJson(200, null, null);
}
//word模板，兩個物件進行追加
public XWPFDocument mergeWord(XWPFDocument document, XWPFDocument doucDocument2) throws Exception {
XWPFDocument src1Document = document;
XWPFParagraph p = src1Document.createParagraph();
//設定分頁符
p.setPageBreak(true);
CTBody src1Body = src1Document.getDocument().getBody();
XWPFDocument src2Document = doucDocument2;
CTBody src2Body = src2Document.getDocument().getBody();
XWPFParagraph p2 = src2Document.createParagraph();
XmlOptions optionsOuter = new XmlOptions();
optionsOuter.setSaveOuter();
String appendString = src2Body.xmlText(optionsOuter);
String srcString = src1Body.xmlText();
String prefix = srcString.substring(0, srcString.indexOf(">") + 1);
String mainPart = srcString.substring(srcString.indexOf(">") + 1, srcString.lastIndexOf("<"));
String sufix = srcString.substring(srcString.lastIndexOf("<"));
String addPart = appendString.substring(appendString.indexOf(">") + 1, appendString.lastIndexOf("<"));
CTBody makeBody = CTBody.Factory.parse(prefix + mainPart + addPart + sufix);
src1Body.set(makeBody);
return src1Document;
}
}
6、Service層的結構：
6-1、Service（controller）
通過Controller層的service方法中的call，來呼叫service層的方法
HttpResponse resp = ServAPIUtil.call("billExcel","GetPropertyCostBillExcelList", params);
通過註解@CAPI寫service層的業務邏輯：
根據 如：通過String prcbIds="a4796bb7-9530a,a4796bb7-9530a,a4796bb7-9530a"多個prcbIds查詢mybatis的要返回的值。
6-2、Service（service）
6-3、ServiceImpl
6-4、通過mapper來介面，到Dao層查詢所需欄位
6-5、resources-Mapper
6-6、mapper的sql語句查詢
後端基本可以了，但是還是有些問題
前端：
新增批量匯出、全選的按鈕。第三個紅色長方形裡面是用vue繫結的id、value、v-model
圈中表示：prcbIds為一個數組
通過ajax檔案下載給後臺拿到prcbIds資料。
如：String prcbIds="a4796bb7-9530a,a4796bb7-9530a,a4796bb7-9530a"
複選框的設定：
