How to rearrange fields in spring roo

[bluecolon]

I'm newbie in spring roo

I want to rearrange fields get a field ids to first. I swap positions between userName field and ids field and try to run webUI but webUI still as before(the first is Username field). Have any idea?

  public class Users {
  
      @NotNull
      @Size(min = 5)
      private String userName;
  
      @NotNull
      private String ids;
  
      @NotNull
      private String positions;
  
      private Float salary;
  }
