Hi All,
I'm using Guice 2.0 to inject a class with values from a properties
file using the @Named annotation with Names.bindProperties() as well
as static injection using binder.requestStaticInjection() to wire
Guice.
As an example my static class "Properties" with property keys contains
inject bindings as follows
private static final String DEFAULT_COMPONENT_VERSION =
"2.0";
@Inject(optional = true)
@Named("version")
public static String PROP_COMPONENT_VERSION =
DEFAULT_COMPONENT_VERSION;
The problem I am having is with exceptions. If I don't use
(optional=true) and my property is not defined inside the properties
file, Guice will throw a CreationException. I've been trying to catch
this exception around binder.requestStaticInject() without success
since a exception is throw within the Properties file.
I would like to know how i can accomplish the continuation of the
program flow and simple notify the user on start-up using log("using "
+DEFAULT_COMPONENT_VERSION) instead of a CreationException that Guice
throws which halts everything.
With (optional=true) i never actually know if the Guice bindings fail
or not. If they do then Guice just ignores and continues.
Thanks,
Martin
