JAVA 调用delete()方法删除文件失败

[Java] 纯文本查看 复制代码

File file = new File(Thread.currentThread().getContextClassLoader().getResource("").getPath() + "/init");
FileInputStream fileInputStream = new FileInputStream(file);
fileInputStream.close();
file.delete();

在调用删除方法（file.delete();）之前一定先把流关闭（fileInputStream.close();），否则删除失败
