java中将多个文件打包zip输出

//action 方法

public String createExcelByStayOrQuitForZip() throws Exception {

if(fileName == null || fileName.equals("")){

fileName = new String("表名".getBytes(), "ISO8859-1");

}else {

fileName = new String(fileName.getBytes(), "ISO8859-1");

}

        //tempFolder = session.get("tempFolder") + ""; 

        String secondId = request.getParameter("secondId");

        String firstId = request.getParameter("firstId");

        String archiveNubers=request.getParameter("archiveNumbers");

        iExcelOptionForPersonService.writeExcelForTheDemocraticPartyPersonagesForZip(response, archiveNubers, ""+session.get("tempFolder")+File.separator+"zip"+File.separator+"tempFolder",secondId,firstId);

return null;

//调用导出   由于java的zip打包文件有中文时会出现乱码问题 这样的话可以引进ant,jar包 使用它的zipOutPutstream 打包

    ZipOutputStream out = new ZipOutputStream(response.getOutputStream());

out.setEncoding("gbk");

for(String archiveNumber:archiveNumbers.split(",")){

byte[] buffer1 = new byte[1024];

 

File filefolder = new File(tempFolder);

if(!filefolder.exists()){

filefolder.mkdirs();

}

 

Map<String, List<InfoValue>> map = selectAllInfoByArchiveNumber(archiveNumber);

String nameForzip=map.get("01-01_001")!=null&&map.get("01-01_001").get(0).getvVarchar()!=null?map.get("01-01_001").get(0).getvVarchar():"";

File file = new File(tempFolder+File.separator+nameForzip+"-"+archiveNumber+".xls");

file.deleteOnExit();

file.createNewFile();

----------------------------------------------------------------------------

FileInputStream fis = new FileInputStream(file); 

out.putNextEntry(new ZipEntry(file.getName()));

int len;

while ((len = fis.read(buffer1)) > 0) {

out.write(buffer1, 0, len);
