easyexcel zipoutputstream

easyexcel是一个Java库，用于将Excel文件导入导出。在pom.xml文件中导入easyexcel库的方法是添加以下依赖项：

<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>easyexcel</artifactId>
    <version>2.0.5</version>
</dependency>

而zipOutput()方法是一个用于将数据导出为zip文件的方法。它接受一个HttpServletResponse对象、一个ByteArrayOutputStream对象和一个文件名作为参数，并将数据写入zip文件中。该方法的核心代码如下：

private void zipOutput(HttpServletResponse response, ByteArrayOutputStream out, String fileName) throws IOException {
    ZipOutputStream zipout = null;
    InputStream inputStream = null;
    try {
        response.setContentType("application/force-download");
        response.addHeader("Access-Control-Expose-Headers", "Content-Disposition");
        response.setHeader("Content-Disposition", "attachment; filename=" + new String((fileName + ".zip").getBytes("UTF-8"), "ISO8859-1"));

        inputStream = new ByteArrayInputStream(out.toByteArray());
        zipout = new ZipOutputStream(response.getOutputStream());

        // 将Excel文件写入zip文件
        zipout.putNextEntry(new ZipEntry(fileName + ".xlsx"));
        int len;
        byte[] buf = new byte[1024];
        while ((len = inputStream.read(buf)) > 0) {
            zipout.write(buf, 0, len);
        }
    } catch (IOException e) {
        LOGGER.error(e.getMessage(), e);
        LOGGER.error("zipFiles exception:{}", e.getMessage());
    } finally {
        if (zipout != null) {
            zipout.close();
        }
        if (inputStream != null) {
            inputStream.close();
        }
    }
}

以上是导入easyexcel库和使用zipOutput()方法导出数据的相关代码。
