To implement dynamic proxy through JDK, classes with proxy requirements (called implementation classes) must implement interfaces. The dynamic proxy can segment the logic and implement the logic through the proxy generation. Other operations can be performed during this period. JDK's dynamic proxy mainly involves two classes in the Java. Lang. Reflect package: proxy and invocationhandler. Invocationhandler is an interface that defines the cross-cutting logic by implementing this interface and ca
