本文整理了Java中org.openl.util.IOUtils.copyAndClose()方法的一些代码示例，展示了IOUtils.copyAndClose()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。IOUtils.copyAndClose()方法的具体详情如下：
包路径：org.openl.util.IOUtils
类名称：IOUtils
方法名：copyAndClose

IOUtils.copyAndClose介绍

[英]Copy bytes from InputStream to an OutputStream and close them after.

This method uses the provided buffer, so there is no need to use a BufferedInputStream.

The buffer size is given by #DEFAULT_BUFFER_SIZE.
[中]将字节从InputStream复制到OutputStream，然后关闭它们。
此方法使用提供的缓冲区，因此不需要使用BufferedInputStream。
缓冲区大小由#默认_buffer_size给出。

public static File toTempFile(InputStream source, String fileName) {

    IOUtils.copyAndClose(source, new FileOutputStream(file));
  } catch (IOException e) {
    final Logger log = LoggerFactory.getLogger(FileTool.class);
    log.error("Error when creating file: {}", fileName, e);
  }
  return file;
