JAVA CMD 特殊字符的转义

Java 调用外部cmd/c 执行外部命令会碰到一些特殊字符, 其实除了空格还有一些的, 看看cmd/? 吧.

笔者就试过XP能run, 弄到2003就不行了, 2003的不是有program files (x86) ?

=================================================

需要引号的特殊字符是:
     <space>
     &()[]{}^=;!'+,`~

=================================================

用双引号把这些字符包含起来就好了.

/** * When executing command line on windows, we must replace the special characters * @param inputDir The inputed directory we need to convert * @return The converted directory */ public String replaceSpecialCharForCmd(String inputDir) { if (this.isWindows()) { final String specialChars = " &()[]{}^=;!'+,`~"; char c; StringBuilder sb = new StringBuilder(inputDir.length()*3); for (int i = 0; i < inputDir.length(); ++i) { c = inputDir.charAt(i); if (specialChars.indexOf(c) >= 0) { sb.append('"').append(c).append('"'); } else { sb.append(c); } } return sb.toString(); } return inputDir; }
