java 将多个文件打包成一个zip后进行下载

ZipOutputStreamout=newZipOutputStream(newFileOutputStream(zipFileName));

for(inti=0;i<fileList.size();i++){

Stringfilename=(String)fileList.get(i);

Filefile=newFile(filename);

zip(out,file);

}

out.close();

下载的如下：

privateintblockSize=65000;

Filefile=newFile(sourceFilePathName);

FileInputStreamfileIn=newFileInputStream(file);

intreadBytes=0;

readBytes=fileIn.read(b,0,blockSize);

totalRead+=readBytes;

out.write(b,0,readBytes);
