I am trying to get value of total number of raw in my table in spring roo project. This can be done by built-in method of Spring roo's aspectJ file.

The method defined as the below in UserAccount_Roo_Jpa_ActiveRecord.aj file:

  public static long UserAccount.countUserAccounts() {
         return entityManager().createQuery("SELECT COUNT(o) FROM UserAccount o", Long.class).getSingleResult();
  }

I want to print this long value to my jspx page. How to call this method and from where? Need help. Thnx.

有帮助吗?

Customize the Controller method that handles the related request:

1: Push-in the controller method you,e.g. show method

2: Modify that method run the query and place the result available for view layer:

@RequestMapping(value = "/{id}", method = RequestMethod.GET)
public String show(@PathVariable("id") Long id, Model uiModel) {
    ...
    Long count = UserAccount.countUserAccounts();
    uiModel.addAttribute("countUserAccounts", count);
    ...
}

3: Modify the jspx as needed.
