开始想到String.replaceFirst(regex, replacement)和String.replaceAll(regex, replacement);

但特殊字符没替换成功。

用法：StringUtils.replace("目标字符串","需要替换的内容","替换成的内容");

public static void main(String[] args) {

String t="asdf#{}sadf;kal#{}";

System.out.println(t.indexOf("#{}"));

String replace = StringUtils.replaceOnce(t,"#{}","<input>");

System.out.println(replace);

}
