MultipartFile 转成InputStream

要将MultipartFile转换为InputStream，可以使用以下代码:

public InputStream multipartToInputStream(MultipartFile multipartFile) throws IOException {
    InputStream inputStream = null;
    File file = null;
    try {
        file = File.createTempFile("temp", null);
        multipartFile.transferTo(file);
        inputStream = new FileInputStream(file);
    } catch (Exception e) {
        e.printStackTrace();
    } finally {
        file.deleteOnExit();
        inputStream.close();
    }
    return inputStream;
}

这段代码首先创建一个临时文件，然后将MultipartFile对象转存到临时文件中。接着使用文件创建一个InputStream流对象，并返回该流对象作为结果。最后，记得在最终使用完InputStream后，删除临时文件并关闭流对象。这样就成功将MultipartFile转换为InputStream了。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
