java实现 上传压缩包，解压，实现打zip压缩包

1、打压缩包
@RequestMapping(value = “/exportAllDutyFiles”, method = RequestMethod.GET)
@ResponseBody
public void exportAllDutyFiles(HttpServletResponse response, HttpServletRequest request) {
File sourceFile=new File(uploadPerformance);
if(!sourceFile.exists()){
throw new RuntimeException(uploadPerformance + “不存在！”);
}
String path=uploadPerformance +".zip"; //压缩包路径名称
File targetFile=new File(path);
List fileList=new ArrayList();
fileList.addAll(Arrays.asList(sourceFile.listFiles()));
ExcelUtil.zipFiles(fileList,targetFile);
downloadFile(targetFile,response,true);
}

/**
* 将多个Excel打包成zip文件
* @param srcfile
* @param zipfile
*/
public static void zipFiles(List srcfile, File zipfile) {
byte[] buf = new byte[1024];
try {
// Create the ZIP file
ZipOutputStream out = new ZipOutputStream(new FileOutputStream(zipfile));
// Compress the files
for (int i = 0; i < srcfile.size(); i++) {
File file = srcfile.get(i);
FileInputStream in = new FileInputStream(file);
// Add ZIP entry to output stream.
out.putNextEntry(new ZipEntry(file.getName()));
// Transfer bytes from the file to the ZIP file
int len;
while ((len = in.read(buf)) > 0) {
out.write(buf, 0, len);
}
// Complete the entry
out.closeEntry();
in.close();
}
// Complete the ZIP file
out.close();
} catch (IOException e) {
e.printStackTrace();
}
}

public void downloadFile(File file,HttpServletResponse response,boolean isDelete) {
	try {
		// 以流的形式下载文件。
		BufferedInputStream fis = new BufferedInputStream(new FileInputStream(file.getPath()));
		byte[] buffer = new byte[fis.available()];
		fis.read(buffer);
		fis.close();
		// 清空response
		response.reset();
		OutputStream toClient = new BufferedOutputStream(response.getOutputStream());
		response.setContentType("application/octet-stream");
		response.setHeader("Content-Disposition", "attachment;filename=" + new String(file.getName().getBytes("UTF-8"),"ISO-8859-1"));
		toClient.write(buffer);
		toClient.flush();
		toClient.close();
		if(isDelete)
		{
			file.delete();        //是否将生成的服务器端文件删除
		}
	}
	catch (IOException ex) {
		ex.printStackTrace();
	}

}

上传压缩包
@RequestMapping("/importZipData")
@ResponseBody
public JSONObject importZipData(MultipartFile file) {
JSONObject json = new JSONObject();
json.put(“status”, “200”);
json.put(“message”, “上传成功”);
// 判断源文件是否存在
if (file == null) {
json.put(“status”, “500”);
json.put(“message”, “上传文件不存在”);
}
// 开始解压
ZipFile zipFile = null;
try {
// 判断路径是否存在
String temp=zipPath+File.separator+“temp”;//用来存放解压后的文件
File dir = new File(temp);
if (!dir.exists()) {
dir.mkdirs();
}
String targetPath = zipPath + File.separator + file.getName();
File saveFile = new File(targetPath);
if (!saveFile.getParentFile().exists()) {
saveFile.getParentFile().mkdirs();
}
file.transferTo(saveFile);
zipFile = new ZipFile(saveFile); //创建ZipFile
zipFile.setFileNameCharset(“UTF-8”); //防止乱码
zipFile.extractAll(temp);//将zip进行解压
File fileTemp = new File(temp);
// 获取路径下的所有文件
File[] files = fileTemp.listFiles();
for (int i = 0; i < files.length; i++) {
File newFile=files[i];
}
} catch(Exception e) {
json.put(“status”, “500”);
json.put(“message”, “上传失败”);
}
return json;
}
