Introduce spring AOP before introducing three common proxy methods: Static agent, dynamic agent, Cglib agentAgent Overview:Proxy is a design pattern that provides additional access to the target object, which is accessed through the proxy. The benefit is that additional functionality can be enhanced based on the target object implementation. (extends the capabilities of the target object).Example: Star (Den
