ValidationUtils#validateInputs
Hi,
This is regarding the following validation method we have in
ValidationUtils:
/public static <T extends VdcActionParametersBase>
ArrayList<String> validateInputs(List<Class<?>>
validationGroupList, T parameters);/
I there any particular reason for supporting the validations only
on objects of classes derived from VdcActionParametersBase? I
guess this was done because this method is primarily intended to
validate the action parameters passed to a BLL action, using the
validation annotations on the parameter class. However I think
this method can be useful for general use as well. e.g. I cannot
add a "@Valid" annotation on a "list" or a "map" in a parameter
class. So I need to iterate over the list/map, and validate each
element inside the loop. The validation inside the loop can also
utilize the above method if the restriction "extends
VdcActionParametersBase" is removed. This will allow me to do the
following in the canDoAction method:
protected boolean canDoAction() {
...
for(GlusterBrickEntity brick :
getParameters().getGlusterVolume().getBricks()) {
List<String> errors =
ValidationUtils.validateInputs(getValidationGroups(), brick);
if(errors != null) {
for(String error : errors) {
addCanDoActionMessage(error);
}
}
}
...
}
Regards,
Shireesh

i don't think there is a reason to restrict only for
VdcActionParametersBase, roy what do you think?
also you can use here
getReturnValue().getCanDoActionMessages().addAll(errors);
instead of going over on all errors.
pls see SetupNetworksParameters.java for validating a list of network
interfaces.
hibernate validator supports trivial object graphs and members that are
arrays, list and java.util.map implementations.
If your code looks like that it should work. If you are using special
validation groups please add them to your command with addValidationGroups.
this should work:
GlusterCommandParameters.java
@Valid
List<Bricks> bricks
Bricks.java
@NotNull
Guid id
