StringUtils.appendCompactedString介绍

[英]This method appends a string to a string builder and collapses contiguous white space is a single space. This is equivalent to: destination.append(source.replaceAll("\s+", " ")) but does not create a Pattern object that needs to compile the match string; it also prevents us from having to make a Matcher object as well.
[中]此方法将字符串附加到字符串生成器，并将连续的空白折叠为单个空格。这相当于：目的地。append（source.replaceAll（“\s+”，“”）），但不创建需要编译匹配字符串的模式对象；它还可以防止我们制作匹配器对象。
