~~###### 碰上系统级的Bug没办法,
读取文件报错,拒绝访问。
文件名中有下划线,
确认文件路径正确。
~~把下划线取消后读取正常,
这个是什么bug?~~
具体是这样的:
手动复制该文件到盘根目录程序不能读取,
重新命名后能程序可以读取。
程序复制到盘符根目录下也不能读取,
重新命名也不能被程序读取。
抓狂了...
系统Win 7,
默认简体中文字符。
经试验改成英文也失败。
请教各位大佬了,
感谢。

我都是按照网上配置的,有些应用只能以普通用户身份(而不是root打开),所以我想要个普通身份登陆的。
我现在进去就是root的登陆画面,但是shell和应用都启动不来。
谢谢。

我是这么写的,
dump -0uan -f /tmp/server-full-backup-`date '+%d-%B-%Y'`.dump /
肯定不对啊,把cdrom proc都备份进去了
还原的时候

2究竟该怎么dump整个系统啊
多谢了。
网上只举了备份了某个目录的例子,都找不到备份整个系统的例子,坑。

我没有中文啊,为什么也乱码
原字符
42 "SmallBeer" 3 5 1 3 2 6 1 1 0 2 130 1 40 1 2 0 0 0 20 60 |
到程序里面是
String s = "42 \"SmallBeer\" 3 5 1 3 2 6 1 1 0 2 130 1 40 1 2 0 0 0 20 60 | \r\n";
byte[] _b = s.getBytes("US-ASCII");
byte[] _bn = s.getBytes();
byte[] _bu = s.getBytes("UTF-8");
System.out.println(_b.toString());
Arrays.asList(_b).forEach(
b->{System.out.print(b+" ");});
System.out.println();
System.out.println(_bn.toString());
Arrays.asList(_bn).forEach(
b->{System.out.print(b+" ");});
System.out.println();
System.out.println(_bu.toString());
Arrays.asList(_bu).forEach(
b->{System.out.print(b+" ");});
结果output
[B@74b0dfcd
[B@74b0dfcd
[B@32a87423
[B@32a87423
[B@20220e64
[B@20220e64
怎么完全不一样。
啊!啊!!啊!!!

</div>
</form>

我试了,直接return false不会跳,但是 return CheckPost();还是会走到test.php
尽管途中出了alert警示窗
为什么,不太懂
{代码...}

本来是"UTF-8"编码,是没有乱码的,
但是我写程序老是容易会中英字符混淆,就是因为输入法切换导致中文符号混入,于是我windows更新成
non-Unicode程序默认用英文。
然后之前写的中文字符串全都变乱码了,但是网页是正常的。
现在写的中文字符串代码里不是乱码,但是网页里是乱码,请问我该怎么办?
谢谢。

java里面为什么List result会自动更新的?就是因为传的是引用吗?
public static void main(String[] args) throws IOException{
Path startingDir = Paths.get("C:\\apache-tomcat-8.0.21");
List<Path> result = new LinkedList<Path>();
Files.walkFileTree(startingDir, new FindJavaVisitor(result));
System.out.println("result.size()=" + result.size());
}
private static class FindJavaVisitor extends SimpleFileVisitor<Path>{
private List<Path> result;
public FindJavaVisitor(List<Path> result){
this.result = result;
}
@Override
public FileVisitResult visitFile(Path file, BasicFileAttributes attrs){
if(file.toString().endsWith(".java")){
result.add(file.getFileName());
}
return FileVisitResult.CONTINUE;
}
}
