/**
* Annotation used for injecting Spring managed beans into objects within Stripes
* (usually ActionBeans). The value of the annotation represents the name of the bean
* in the Spring application context to inject. If the value is omitted then Stripes
* will attempt to auto-wire first by property/field name and then by type.
*
* Both methods and fields can be annotated. If a field is annotated Stripes will use
* field access to attempt to inject the bean into the field. If a method is annotated Stripes
* will attempt to invoke the method and supply it the value to inject. In both cases
* non-public fields/methods are supported (i.e. values can be injected into private fields
* and through private methods).
*
* For a more details description of the injection process and how auto-wiring occurs
* when explicit bean names are omitted see the {@link SpringHelper} class.
