截取中文字符串，做成标签。

不说了，上代码：

 

public class Functionsx { public static String abbreviate(String str, int width, String ellipsis) { if (StringUtils.isBlank(str)) { return ""; } String regex = "[/u4e00-/u9fa5/ufe30-/uffa0]+$"; int w = 0;// string width int l = 0;// string length for (char s : str.toCharArray()) { w = String.valueOf(s).matches(regex) ? w + 2 : w + 1; if (w > width) { break; } l++; } return w > width ? str.substring(0, l) + ellipsis : str.substring(0, l); } }

 

做成标签：
