今天项目里面用到了下载打包的功能，想了一会还是用java实现比较好，一开始想着在linux里面编写shell脚本用zip命令打包，可是实现后zip命令压缩里面总是带有目录，除非在当前目录压缩。后来改成Java实现，用到apache的工具包ant.jar

具体代码如下
public static void main(String argv[]) {
try {
byte b[] = new byte[512];

//压缩文件的保存路径
String zipFile = "/tmp/test.zip";

            //压缩文件目录
             String file1 = "/tmp/A9IPL00417_BGSYA0909070000800.zip";
             String file2 = "/tmp/Q9IPL00417_BGSYA0909070000800.zip";
             String file3 = "/tmp/CA9IPL00417_BGSYA0909070000800.zip";

             List fileList = allFile(file1);
              fileList = allFile(file2);
              fileList = allFile(file3);

             FileOutputStream fileOutputStream = new FileOutputStream(zipFile);
            //使用输出流检查
             CheckedOutputStream cs = new CheckedOutputStream(fileOutputStream, new CRC32());
            //声明输出zip流
             ZipOutputStream ut = new ZipOutputStream(new BufferedOutputStream(
                     cs));

            for (int i = 0; i < fileList.size(); i++) {
                InputStream in = new FileInputStream((String)fileList.get(i));
                String fileName = ((String)(fileList.get(i))).replace(File.separatorChar,'/');
                System.out.println("ziping " + fileName);
                fileName = fileName.substring(fileName.lastIndexOf("/")+1);
                System.out.println(fileName);
                ZipEntry e = new ZipEntry(fileName);
                out.putNextEntry(e);
               int len = 0;
               while((len = in.read(b)) != -1) {
                    out.write(b,0,len);
                  }
                out.closeEntry();
             }
             out.close();
             Thread.sleep(1000);
