Spring 3.0 MVC @ModelAttribute - order of properties

[BaumTom]

Hello,

I use a controller class that has a method with a @ModelAttribute parameter:

@Controller()
public class SomeController {

  @RequestMapping({ "/show" })
  public ModelAndView show(@ModelAttribute("entry") SomeEntry entry) {
    return new ModelAndView("show");
  }

}

public class SomeEntry {
  
  private String a;
  private String b;
  private String c;

  public String getA() {
    return a;
  }

  public void setA(String a) {
    this.a = a;
  }

  public String getB() {
    return b;
  }

  public void setB(String b) {
    this.b = b;
  }

  public String getC() {
    return c;
  }

  public void setC(String c) {
    this.c = c;
  }

}

When the @ModelAttribute "entry" is filled in a POST request, the setters of "entry" are called in the following order:
1. setA
2. setB
3. setC

Can I specify in which order the setters are called? For example:
1. setC
2. setA
3. setB

Regards
Thomas

No, you can't do it. The order come from request.getParameterMap().entrySet()

Ok.

I have to ensure that, in my example, setC is called before setA. Is there any way to do that?

Bind parameters to variables and fill your model in the order that you want.
