java如何获取冒号后面参数的方法

    String regEx=":[\\S]+";
    String sql=" select * from a where id=:id and name=:zhangsan ";
    Pattern p = Pattern.compile(regEx); 
    Matcher m = p.matcher(sql); 
     while(m.find()) {
       System.out.println(m.group());
     }

public class Test_Leo
{
  public static void main(String[] args)
  {
    String data = "=calc|A!Z  666";
    Pattern pattern = Pattern.compile("^[+-@=](.*?)\\d$");
    Matcher matcher = pattern.matcher(data);
    if(matcher.find())
    {
      System.out.println(matcher.group());
    }else{
      System.out.println("nothing");
    }
  }
  
}
