Not sure if this helps or not but you cannot use the Spring
<context:annotation-config />
markup in your GAE Spring applications ...
This will of course work locally but because the
CommonAnnotationBeanPostProcessor attempts to load
javax.annotation.Resource (and fails) then no annotation processing
will occur ...
there are 2 workarounds to this:
1) use the init-method="..." attribute of the <bean ... /> element
or ...
2) directly load the appropriate annotation processing beans like so:
<bean
class="org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor"
/
>
<bean
class="org.springframework.context.annotation.ConfigurationClassPostProcessor" /
>
<bean
class="org.springframework.beans.factory.annotation.InitDestroyAnnotationBeanPostProcessor">
<property name="initAnnotationType"
value="javax.annotation.PostConstruct" />
<property name="destroyAnnotationType"
value="javax.annotation.PreDestroy" />
</bean>
This avoids the attempt to load the @Resource class ...
