Are static setter/getters allowed?

[moo]

maybe someone asked that before... I could'nt find any restrictions relating to the usage of static setter/getters. are they allowed in spring?

Well, Spring is focused around beans and their instances, but static getters and setters will work just fine.

I think the instrospector don´t recognize static getter/setter as a property ... ( at least it don´t display here in jbuilder ) ... I remeber I tried that with spring but i couldn't make it work ... anyway I refactored it and it´s running now

.... i don't know sun's bean specification by heart but i can't remember it saying explicitly that using static bean access is forbidden....

public class Person {
  private static String id;
 
  public static String getId() {
    return id;
  }
  public static void setId(String id) {
    Person.id = id;
  }
}

edit: it's not that important though....

Spring use the Introspector to find property set and get methods, so if you provide your own BeanInfo, I guess static get/set would work alright...

Don't do it. How would you mock/stub that class? You can't of course. Use a Singleton bean instead.
