包路径：java.lang.reflect.InvocationHandler
类名称：InvocationHandler

InvocationHandler介绍

[英]InvocationHandler is the interface implemented by the invocation handler of a proxy instance.

Each proxy instance has an associated invocation handler. When a method is invoked on a proxy instance, the method invocation is encoded and dispatched to the invokemethod of its invocation handler.
[中]InvocationHandler是由代理实例的调用处理程序实现的接口。
每个代理实例都有一个关联的调用处理程序。在代理实例上调用方法时，方法调用将被编码并发送到其调用处理程序的invokemethod。
