尝试在Linux上使用java文件io创建文件？

无法在linux服务器上创建文件，无法在本地测试文件上正常工作。请帮我解决这个问题我不知道发生了什么dir-exist但是html-not-exist它应该从代码中创建

我的代码：

File file = new File(dirFileName);
        file.delete();
        file.createNewFile();
        DataOutputStream dataOut = new DataOutputStream(new FileOutputStream(file));
        dataOut.writeBytes(view);

从开发人员机器（通常是Windows）过渡到linux服务器时可能导致问题的两个常见问题是

-区分大小写。在linux服务器上，tou应该检查路径是否也有效，不区分大小写。例如，如果文件系统中有一个名为dirfilename的文件夹，并且您的java路径是“dirfilename”，那么这将在windows上工作，但在linux服务器上不工作

-文件权限。运行您的程序的jvm可能由对您尝试访问的路径没有权限的用户运行。 您可以使用

---

“ps aux”命令。

查看错误，它告诉您

dirFileName/home/bms/html/webversion/BzAEqwsEk20Fk21Pl30Qj33Ss26Aj17BcdDZrt.html

不存在。检查路径是否正确。可能重复：这是原始路径，它存在/home/bms/html/webversion/dirFileName未随附其刚刚使用print语句打印。异常消息表明，运行Tomcat的计算机上不存在此目录路径

/home/bms/html/webversion

。
