JAVA中使用JXL操作EXCEL

Workbook rwb = null;

workbookSettings.setEncoding("GB2312");

try {
rwb = Workbook.getWorkbook(is, workbookSettings);
} catch (IOException e) {
e.printStackTrace();
} catch (BiffException e) {
e.printStackTrace();
}

log.info("开始导入数据.....");
String inputTypeDimension = param.get("inputTypeDimension").toString();
processXslFileMonth2(rwb,param);

Sheet rs[] = rwb.getSheets();
if (rs == null && rs.length == 0)
throw new AppException("数据为空!!");

try {
for (int shc = 0; shc < rs.length; shc++) {

}

log.info("Sheet" + shc + "中有:" + getRightRows(rs[shc]) + "行");
}

String begin_date = param.get("begin_date").toString();
String end_date = param.get("end_date").toString();
