然后我去查了StringUtils.overlay的源码方法。

public static String overlay(final String str, String overlay, int start, int end) {
        if (str == null) {
            return null;
        }
        if (overlay == null) {
            overlay = EMPTY;
        }
        final int len = str.length();
        if (start < 0) {
            start = 0;
        }
        if (start > len) {
            start = len;
        }
        if (end < 0) {
            end = 0;
        }
        if (end > len) {
            end = len;
        }
        if (start > end) {
            final int temp = start;
            start = end;
            end = temp;
        }
        return str.substring(0, start) +
            overlay +
            str.substring(end);
    }

也是做了一个字符串截取与拼接。
