Question

如何通过 HttpServletRequest 用正则表达式把 {locationId} 中内容获取到
求教！！！！谢谢！！！！！

Answer 1

你可以通过 spring的注解@PathVariable来获得locationId public Result method(@PathVariable String locationId) 你也可以通过string 的split来截取 public class Test{ public static void main(String[] args){ String url = "/result/last/location/{locationId}/*"; String result = getStr(url,"location"); System.out.println(result); } public static String getStr(String url,String key){ if(url == null || key == null){ return ""; } String[] strs = url.split("/"); for(int i=0;i<strs.length;i++){ if(strs[i].equals(key)&&i<strs.length-1){ return strs[i+1]; } } return ""; } }

Answer 2

"{[}]"提取括号的内容的正则你试试看

@PathVariable 是比较好的方式
