匯出複雜木板使用這個老哥的東西很好用

很方便的完成了，插入圖片也有，只需要把圖片轉換成位元組流。程式碼如下
//初始化工具 ExcelTemplate excel = new ExcelTemplate(filePath + fileName); /*javaBean轉map*/ Map<String, Object> map = getSevenInfo(affairSevenKnowledge);// 第一個引數，需要操作的sheet的索引 // 第二個引數，需要複製的區域的第一行索引（佔位符所在的第一行） // 第三個引數，需要複製的區域的最後一行索引（佔位符所在的最後一行） // 第四個引數，需要插入的位置的索引(佔位符的下一行) // 第五個引數，填充行區域中${}的值 // 第六個引數，是否需要刪除原來的區域 // 需要注意的是，行的索引一般要減一 try { excel.fillVariable(0, (Map<String, String>) map.get("param"));int i = excel.addRowByExist(0,14,14,15, (LinkedHashMap<Integer, LinkedList<String>>) map.get("rows"),true); //家庭成員和主要社會關係下方多處來的列合併到一個單元格 //沒有關係就不需要合併了 if (i>0){ // excel.mergedRegion(0,16,16+i+1,1,1); } // excel.addRowByExist(0,14,14,15,rows,true);} catch (IOException e) { e.printStackTrace(); } // 第一個引數，需要操作的sheet的索引 // 第二個引數，替換sheet當中${<變數的值>}的值 //下載 try { // 清除buffer快取 response.reset(); response.setContentType("application/octet-stream; charset=utf-8"); //指定下載名字 response.setHeader("Content-Disposition", "attachment; filename="+ Encodes.urlEncode(affairSevenKnowledge.getName()+fileName)); response.addHeader("Pargam", "no-cache"); response.addHeader("Cache-Control", "no-cache"); OutputStream fout = response.getOutputStream(); excel.getWorkbook().write(fout); fout.close(); } catch (IOException e) { e.printStackTrace(); }
匯出word模板使用的這個老哥的東西
https://blog.csdn.net/qq_27828675/article/details/88708983
匯出word模板還是挺坑的，word是由xml組成的。再word裡編輯好佔位符後，轉成xml文件會發現，佔位符已經分開了。我使用數字做佔位符，轉換成xml後把數字轉換成需要的佔位符。但是，
轉換完後，有些佔位符還是無法替換，再次轉成xml發現，佔位符還是分開了。。。。最後
我看了下老哥寫的程式碼，我給改動了下，模板未匹配到的區域我給替換成了空字串。修改後的程式碼如下
