How to inject dependencies in Valang custom functions
If your custom function requires dependencies to be injected (like a DAO for example) just override one of the isAutowire... methods of org.springmodules.validation.valang.functions.AbstractFunction.
For example, if you add this to your custom function:
@Override
public boolean isAutowireByName() {
return true;
}
Then Spring will autowire any dependencies by name.
