小编Lyc*_*aye的帖子

我有一个小问题.想要使用Java上的POI API 将新的excel文件(.xlsx)转换为旧的(.xlsx).

我认为这是一个心灵问题,但我不知道存在哪个错误.

我在这里使用这些代码:

import java.io.BufferedOutputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import java.util.Iterator;

import org.apache.poi.hssf.usermodel.HSSFWorkbook;
import org.apache.poi.openxml4j.exceptions.InvalidFormatException;
import org.apache.poi.ss.usermodel.Cell;
import org.apache.poi.ss.usermodel.CellStyle;
import org.apache.poi.ss.usermodel.Row;
import org.apache.poi.ss.usermodel.Sheet;
import org.apache.poi.ss.usermodel.Workbook;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;

public class XLSX2XLS{
    private String outFn;
    private File inpFn;

    public XLSX2XLS(File inpFn){
        this.outFn = inpFn + ".xls";
        this.inpFn = inpFn;
    }

    public void xlsx2xls_progress() throws InvalidFormatException,IOException {
        InputStream in = new FileInputStream(inpFn);
        try {
            XSSFWorkbook wbIn = new XSSFWorkbook(in); …

我如何从jQuery DataTable(https://datatables.net)获取所有选定的行.

这里在stackoverflow中找到了计算所选行的方法,但我需要将选定的行数据抛到下一个JavaServletPage来使用它.

我的DataTables代码配置:
