问题 How can I add or remove Spring AOP proxies in a running application without restarting the server?

问题 I am defining a JobProcess with a method Object process( JobContext jobContext ); with an impl called JobProcessImpl. Whenever this JobProcessImpl.process method is executed, I want to spy with more than one subclass. I want all this subclasses to be executed. The spy class is defined as base class Task to look for JobProcessImpl.process invocation. In the output, I always see that only log from AnnotationTask and not from ReviewTask.

问题 We have a bunch of pdf report classes which after a mass import of archived data have started occaisonally throwing null pointer exceptions when bits of data are missing e.g. thing.getOtherThing().getText(); will not have an OtherThing and the report will fall over.
