Java实现文件压缩

 @GetMapping("/zipFile")
    public void zipFile() throws IOException {
        //这个是文件夹的绝对路径，如果想要相对路径就自行了解写法
        String sourceFile = "E:\\2-project\\15-henanhuagong\\CEPOP\\trunk\\zhnh\\uploadFile\\hnec";
        //这个是压缩之后的文件绝对路径
        FileOutputStream fos = new FileOutputStream(
                "E:\\2-project\\15-henanhuagong\\CEPOP\\trunk\\zhnh\\uploadFile\\hhnec.zip");
        ZipOutputStream zipOut = new ZipOutputStream(fos);
        File fileToZip = new File(sourceFile);

        zipFile(fileToZip, fileToZip.getName(), zipOut);
        zipOut.close();
        fos.close();
    }

    private void zipFile(File fileToZip, String fileName, ZipOutputStream zipOut) throws IOException {
        if (fileToZip.isHidden()) {
            return;
        }
        if (fileToZip.isDirectory()) {
            if (fileName.endsWith("/")) {
                zipOut.putNextEntry(new ZipEntry(fileName));
                zipOut.closeEntry();
            } else {
                zipOut.putNextEntry(new ZipEntry(fileName + "/"));
                zipOut.closeEntry();
            }
            File[] children = fileToZip.listFiles();
            for (File childFile : children) {
                zipFile(childFile, fileName + "/" + childFile.getName(), zipOut);
            }
            return;
        }
        FileInputStream fis = new FileInputStream(fileToZip);
        ZipEntry zipEntry = new ZipEntry(fileName);
        zipOut.putNextEntry(zipEntry);
        byte[] bytes = new byte[1024];
        int length;
        while ((length = fis.read(bytes)) >= 0) {
            zipOut.write(bytes, 0, length);
        }
        fis.close();
    }
