JAvaは複数のexcelをエクスポートしzipパッケージに打つ

ここでは主にデータ量が多すぎる場合に、複数のexcelファイルを生成してzip圧縮パケットに打つダウンロードを提供する.
 
圧縮excelのクラス  ZipUtil:
 

import java.io.*;
import java.util.*;
import java.util.zip.ZipOutputStream;
import java.util.zip.ZipEntry;
import java.util.zip.ZipFile;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;


public class ZipUtil {
    
    private static final Log log = LogFactory.getLog(ZipUtil.class);

    public static void zipFiles(List srcfile, File zipfile) {
        byte[] buf = new byte[1024];
        try {
            // Create the ZIP file
            ZipOutputStream out = new ZipOutputStream(new FileOutputStream(zipfile));
            // Compress the files
            for (int i = 0; i < srcfile.size(); i++) {
                File file = srcfile.get(i);
                FileInputStream in = new FileInputStream(file);
                // Add ZIP entry to output stream.
                out.putNextEntry(new ZipEntry(file.getName()));
                // Transfer bytes from the file to the ZIP file

                while ((len = in.read(buf)) > 0) {

                }
                // Complete the entry

                in.close();

        }
    }

    public static void unZipFiles(File zipfile, String descDir) {
        try {
            // Open the ZIP file
            ZipFile zf = new ZipFile(zipfile);
            for (Enumeration entries = zf.entries(); entries.hasMoreElements();) {
                // Get the entry name
                ZipEntry entry = ((ZipEntry) entries.nextElement());
                String zipEntryName = entry.getName();
                InputStream in = zf.getInputStream(entry);

    /**

    public static void main(String[] args) {
    	List srcfile=new ArrayList();

複数のexcelクラスを生成するには、次の手順に従います.
 

 /**
     * forward:  Excel
     * @throws Exception
     */
    private ModelAndView forwardExport2Excel(HttpServletRequest request, HttpServletResponse response)
    throws Exception{
        try {
        	
	            Integer page=0;//  
	            Integer pagesize=Integer.valueOf(PropertiesUtil.getPropertyValue("PAGESIZE"));//     
	            Integer total=0;//  
	            int pageindex=1;//    
	            Integer rowfrom = 1;
	            Integer rowto = 10;
	        	total =service.getTotal();
	        	if(total list = new ArrayList
