转义字符串中全部字符

public static String escape(String s)
{
	s = s.replaceAll("\"","\\\\\"");
	s = s.replaceAll("\\\\","\\\\\\\\");
	s = s.replaceAll("\'","\\\'");
	s = s.replaceAll("\n","\\\n");
	s = s.replaceAll("\r","\\\r");
	s = s.replaceAll("\b","\\\b");
	s = s.replaceAll("\t","\\\t");
	s = s.replaceAll("\f","\\\f");
	return s;
}

如此字符串中所有可转移的字符将全部转义
