How configure struts2 to get validation rules from Spring via #value - spring

Question

We are using spring 3 and struts 2. We use spring #value annotation to get values from property files.
We want to get validation rules from property files instead of hard-coding them in action.
Here is sample property
system.properties
transfer.account.min.amount=10
Here is the action:
public class TransferToAccount implements Preparable {
#Value("${transfer.account.min.amount}") public String minAmount;
//...........execute and other methods omitted
#IntRangeFieldValidator(type = ValidatorType.FIELD, min = "${minAmount}", key = "validate.int.min")
public void setAmount(Integer amount) {
this.amount = amount;
}
The minAmount is populated correctly by value 10, but the validation is not working.
To see if parameters are passed correctly, I make a test as below.
Assume we want to get a key from spring managed property file ( This is just a test ;) )
system.properties
transfer.account.min.amount.key=validate.int.min
The resource bundle is:
validate.int.min = This field must be more than ${min}
...and we change validation as below:
#IntRangeFieldValidator(type = ValidatorType.FIELD, min = "${minAmount}", key = "${transfer.account.min.amount.key}")
Now when an error happens the validation message shows validate.int.min, instead of fetching this value from resource bundle!
Of course, when you run below code:
#IntRangeFieldValidator(type = ValidatorType.FIELD, min = "${minAmount}", key = "validate.int.min")
The error message is fetched resource bundle correctly!
If I can use annotation in this way, please let me know what is my mistake!
If I can not use annotations like this, please let me know what is the best way to avoid hard coding the validaiton rolls in actions.
