linux下poi操作excel的问题

Question

System.out.println("excek保存路径"+path);
Workbook workbook=null;
Sheet sheet=null;
try {
System.out.println("开始写excel");
workbook = new SXSSFWorkbook(500);
sheet = workbook.createSheet();
workbook.setSheetName(0, fileName);
Row row = sheet.createRow(0);
} catch (IOException e) {
e.printStackTrace();
} 程序走到 workbook = new SXSSFWorkbook(500);这步就停止了这是什么原因

Answer 1

} catch (Exception e) {
e.printStackTrace();
}
加上这个看看输出什么错误

估计是workwook没有500
