一、客户需求：
用户在搜索结果中对需要下载的文档进行选择，系统将选定的一批搜索结果批量下载到服务器上预定义好的目录，然后下载到用户自己的电脑中。
二、解决方案：
1、将选择的NOTE文档中的附件集中拆离到服务器上的指定目录中，
2、将指定的目录压缩；
3、返回链接给用户，用户自己下载保存。
三、程序代码：

//======删除文件夹
public static void deletefile(String delpath)
throws IOException,FileNotFoundException {
File file = new File(delpath);
if (!file.isDirectory()) {
file.delete();
}
else if (file.isDirectory()) {
String[] filelist = file.list();
for (int i = 0; i < filelist.length; i++) {
File delfile = new File(delpath + "\\" + filelist[i]);
if (!delfile.isDirectory())
delfile.delete();
else if (delfile.isDirectory())
deletefile(delpath + "\\" + filelist[i]);
}
file.delete();
}
}
//======
//压缩文件
备注：本段程序只做了对统一文件夹下的文件压缩，如果要对子目录压缩，还需要各位自己改改程序
public void gzip(){
byte[] buf = new byte[1024];
try {
len=srcPath.listFiles().length;
String[] filenames = new String[len];
outFilename=new String(srcPath+".zip");
File[] files = srcPath.listFiles();
for(int i=0;i<len;i++)
{
// if(files[i].isDirectory())
filenames[i]=srcPath.getPath()+File.separator+files[i].getName();
System.out.println("filenames"+filenames[i]);
}
ZipOutputStream out = new ZipOutputStream(new FileOutputStream(outFilename));
for (int i=0; i<filenames.length; i++)
{
FileInputStream in = new FileInputStream(filenames[i]);
out.putNextEntry(new org.apache.tools.zip.ZipEntry(files[i].getName()));
int len;
while ((len = in.read(buf)) > 0)
{
out.write(buf, 0, len);
}
out.closeEntry();
in.close();
}
out.close();
