然后就按照这个demo就可以了，
String mainPath = System.getProperty("user.dir");
String Q1G_Path = mainPath + "/resource/Q1G.xls";
List<Gate> gate_list = new ArrayList<>();
Sheet sheet;
Workbook book;
//Q1G_Path为要读取的excel文件完全路径名
book = Workbook.getWorkbook(new File(Q1G_Path));
//获得第一个工作表对象(ecxel中sheet的编号从0开始,0,1,2,3,....)
sheet = book.getSheet(0);
for (int i = 1; i <= 69; i++) {
Gate gate = new Gate();
gate.id = sheet.getCell(0, i).getContents();//（列，行）;
gate.plane_type = sheet.getCell(5, i).getContents();
gate.arrive_type = sheet.getCell(3, i).getContents();//（列，行）
gate.go_type = sheet.getCell(4, i).getContents();
gate.pucks = new ArrayList<>();
gate_list.add(gate);
}
