上传文件，解压zip

前台使用layui官方上传文件例子：

<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head>
<meta charset="UTF-8">
<title>上传压缩文件</title>
<link rel="stylesheet" type="text/css" href="../../static/admin/layui/css/layui.css" th:href="@{/static/admin/layui/css/layui.css}">
</head>
<body>
	<button type="button" class="layui-btn layui-btn-primary" id="test">
		<i class="layui-icon"></i>只允许压缩文件
	</button>
	<script type="text/javascript" src="../../static/admin/layui/layui.js" th:src="@{/static/admin/layui/layui.js}"></script>
	<script type="text/javascript" th:inline="javascript">
	var ctxPath = [[${#request.getContextPath()}]];
	layui.use('upload', function(){
		var $ = layui.jquery
		,upload = layui.upload;
		upload.render({ //允许上传的文件后缀
			elem : '#test'
			,url : ctxPath+'/admin/zip/singleFileUpload?type=' + '1002'
			,accept : 'file' //普通文件
			,exts : 'zip' //只允许上传压缩文件
			,size: 100*1024 //文件大小限制为100MB
			,done : function(res) {
				console.log(res)
			}
		});
	});
	</script>
</body>
</html>

spring接收文件：

/**
	 * 上传文件
	 * 
	 * @return
	 * @date 2018年9月5日
	 */
	@RequestMapping("/singleFileUpload")
	@ResponseBody
	public Map<String, Object> singleFileUpload(@RequestParam("file") MultipartFile file) {

		Map<String, Object> map = new HashMap<>();

		if (file.isEmpty()) {
			map.put("code", 0);
			map.put("msg", "文件为空");
			map.put("data", null);
		}

		try {
			// 获取文件并且保存到指定位置
			Map<String, String> src = new HashMap<>();
			File newFile = new File(UPLOAD_PATH);
			if (!newFile.exists()) {
				newFile.mkdirs();
			}
			byte[] bytes = file.getBytes();
			Path path = Paths.get(UPLOAD_PATH + file.getOriginalFilename());
			Files.write(path, bytes);
			src.put("src", path.toString());
			map.put("code", 0);
			map.put("msg", "上传成功！");
			map.put("data", src);
		} catch (IOException e) {
			map.put("code", 0);
			map.put("msg", "保存文件出错！");
			map.put("data", null);
			e.printStackTrace();
		}
		return map;
	}

解压上传的zip文件到当前文件夹：

private void unZip(String filePath) {

		// 获取ZIP压缩文件的目录
		String currentPath = filePath.substring(0, filePath.lastIndexOf("\\") + 1);

		try {

			// 创建ZIP文件并制定编码格式
			ZipFile zipFile = new ZipFile(filePath, Charset.forName("GBK"));

			for (Enumeration<? extends ZipEntry> entries = zipFile.entries(); entries.hasMoreElements();) {
				ZipEntry entry = entries.nextElement();
				String name = entry.getName();
				InputStream inputStream = zipFile.getInputStream(entry);
				File file = new File((currentPath + File.separator + name));

				// 判断是否是目录
				if (entry.isDirectory()) {
					file.mkdirs();
					continue;
				}

				FileOutputStream fos = new FileOutputStream(file);
				byte[] b = new byte[1024];
				int read = 0;
				while ((read = inputStream.read(b)) > 0) {
					fos.write(b, 0, read);
				}
				// 关闭
				inputStream.close();
				fos.close();
			}
			// 关闭
			zipFile.close();

		} catch (IOException e) {
			e.printStackTrace();
		}
	}
