A method invocation on a proxy instance through one of its proxy interfaces will be dispatched to the invoke method of the instance's invocation handler, passing the proxy instance,a java.lang.reflect.Method object identifying the method that was invoked, and an array of type Object containing ...
public Object invoke(Object proxy, Method method, Object[] args) throws Throwable { System.out.println(Before invoking method: + method.getName()); Object result = method.invoke(target, args); System.out.println(After invoking method: + method.getName()); return result; } } ``` 然后,我...

proxyObj.business(); 实际上进入的是拦截器中的invoke方法,这时拦截器中的invoke方法中的method参数会被赋值。 为啥这叫JDK动态代理 因为该动态代理对象是用JDK相关代码生成。 很多同学对动态代理迷糊,在于proxyObj.business();理解错了,至少是被表面所迷惑,没有发现这个proxyObj和Proxy之间的联系,一度纠结最后调用的...
proxyObject.method(); } } ``` 在上面的代码中,MyInvocationHandler类实现了InvocationHandler接口,并重写了invoke方法。该方法在被代理对象的方法调用前后分别输出了Before method invocation和After method invocation的信息。通过运行这段代码,我们可以观察到被代理对象的方法调用被拦截,并在原有逻辑前后添加了额外的处理...
