java实现动态更新,可以利用javascipt和远程java的互动完成

package org.excel.model;

import java.io.File;
import java.util.ArrayList;

import jxl.Cell;
import jxl.Sheet;
import jxl.Workbook;

public class Operate {
	
	public String queryById(int line,int row,String xlsname){

		String result = null;
		try {

			 book = Workbook.getWorkbook(new File(xlsname));
			//获得第一个工作表对象
			Sheet sheet = book.getSheet(0);
			//获得单元格
			Cell cell1 = sheet.getCell(line,row);
			result = cell1.getContents();
			System.out.println(result);
			book.close();
