模板导出Excel
数据格式
exportList为List<String>，生成方式为遍历每个对象并将所有属性以|串起来
List<DetectorHistory> dfList = service.getList(); //获取对象集合
//生成的行数
int operatorCount = 0;
List<String> exportList = new ArrayList<String>();
StringBuffer sbList = new StringBuffer();
if (dfList!=null&&dfList.size()>0) {
for (DetectorHistory ele:dfList) {
sbList.delete(0, sbList.length());
//加入|
sbList.append("|");
//加入属性
...
exportList.add(sbList.toString());
operatorCount++;
}
}
导出
//模板所在文件夹路径
String tempPath = req.getSession().getServletContext()
.getRealPath(File.separator + "downLoad"
+ File.separator + "FileTemplate");
//生成文件所在文件夹路径
String exportFilePath = req.getSession().getServletContext()
.getRealPath(File.separator + "downLoad"
+ File.separator + "ExportFile");
//模板文件名,事先生成好以及头文件情况
String templateFileName = "F2TotalTmp.xls";
//生成文件名

JSONObject jsonObject = new JSONObject();
try {
// 文件导出
if (exportList.size() > 0) {
//利用模板生成Workbook

// 写入备注行
String remarkInfo = "tip:辅修学分上限为2分";
// 导出文件路径
String targetFilePath = exportFilePath + File.separator + exportFileName;
//导出文件的文件夹不存在即创建文件
File exportFile = new File(targetFilePath);
if(!exportFile.exists()) {

}
}
