Question

我有一个上传java servlet，它将文件写入临时目录当在Windows上运行代码时它工作正常，但是当我在CentOS上运行时，我得到以下java.io.FileNotFoundException错误。 servlet没有将文件写入/usr/local/jakarta/apache-tomcat-7.0.26/temp。我尝试将每个目录权限设置为rwxrwxrwx但仍然无法正常工作。任何想法可能是什么问题？

Answer 1

您的System.getProperty（“java.io.tmpdir”）位置不存在。它只发生在超过10 KB的文件上，因为只有当文件大小超过10KB时，tomcat才会尝试写入磁盘。

我希望这会有所帮助

Answer 2

我正在使用由GWT gwtupload servlet创建的FileItem，这导致了错误。我创建了一个临时文件，并将FileItem的内容复制到我的新临时文件中。

File file = File.createTempFile("upload-", ".xls");
item.write(file);

使用java servlet上传到temp时的java.io.FileNotFoundException
