Question

@SpringBean
PDLocalizerLogic loc;

When using above I receive java.io.NotSerializableException. This is because loc is not serializable, but this shouldn’t be problem because spring beans are a serializable proxies.
I’m using wicket-spring library, and as injector SpringComponentInjector, where wrapInProxies is by default set to true, so I think that proxies should be created, but they aren’t.

On the page https://cwiki.apache.org/WICKET/spring.html#Spring-AnnotationbasedApproach is written:

Using annotation-based approach, you
should not worry about
serialization/deserialization of the
injected dependencies as this is
handled automatically, the
dependencies are represented by
serializable proxies

What am I doing wrong?

Answer 1

Do you know how the bean is being injected?

1. Through component initialization (i.e. a Component and being filled in by the SpringComponentInjector)
2. Some other object using InjectorHolder.getInjector().inject(this)?
3. Injected directly by spring (i.e. this is a spring bean where the property is being set by Spring configuration)

Cases 1 and 2 would use wicket-spring integration and would wrap the bean with a wicket proxy which is serializable.
Case 3 would only provide you whatever spring passes to you without wrapping.
