The general idea that an existing module or component can be changed by injecting additional behavior has been originally developed within aspect-oriented programming (AOP). And then this idea has been implemented in various frameworks like Spring (yet, not in its original form).

Cool. Another example could be of IPC in distributed operating systems borrowing from message-passing in CSP or the Actor model although, it could be also be the other way around?
