後臺代碼，這是基礎方法，還要根據使用調用
public static void exportExcel(HttpServletResponse response, String sheetName, String fileName, String[] header, List<String[]> content)
throws IOException {
// 清空response
response.reset();
// 設置response的Header
response.setHeader("Content-disposition",
"attachment;filename=" + new String(fileName.getBytes("gbk"), "iso8859-1") + ".xlsx");
response.setContentType("application/vnd.ms-excel;charset=gb2312");
Sheet sheet = new Sheet(1, 0);
sheet.setSheetName(sheetName);
// 設置自適應寬度
sheet.setAutoWidth(Boolean.TRUE);
// 設置表頭
List<List<String>> list = new ArrayList<>();
for (int i = 0; i < header.length; i++) {
list.add(Collections.singletonList(header[i]));
}
sheet.setHead(list);
OutputStream outputStream = null;
ExcelWriter writer = null;
try {
outputStream = new BufferedOutputStream(response.getOutputStream());
writer = EasyExcelFactory.getWriter(outputStream);
List<List<Object>> data = new ArrayList<List<Object>>();
for (int i = 0; i < content.size(); i++) {
List<Object> item = new ArrayList<Object>();
for (int j = 0; j < content.get(i).length; j++) {
item.add(content.get(i)[j]);
}
data.add(item);
}
writer.write1(data, sheet);
outputStream.flush();
log.info("excel文件導出成功!");
} catch (Exception e) {
log.error("excel文件導出失敗, 失敗原因：{}", e);
} finally {
try {
if (writer != null) {
writer.finish();
}
if (outputStream != null) {
outputStream.close();
}
} catch (IOException e) {
log.error("excel文件導出失敗, 失敗原因：{}", e);
}
}
}
