不同于ProxyFactory和ProxyFactoryBean 给单个bean增加代理。spring提供了基于一定规则自动发现和代理。public abstract class AbstractAutoProxyCreator extends ProxyProcessorSupport implements SmartInstantiationAwareBeanPostProcessor, BeanFactoryAware {ProxyProcessorSupport 继承自Pro.

Advisor接口，holding advice（action to take at a joinpoint，在连接点上执行的动作）和pointcut。Advice EMPTY_ADVICE = new Advice() {};Advice getAdvice(); 返回aspect切面的advice部分，advice可以是Interceptor，before advice或者throws advice等，如果pointcut匹配到的话 就返回对应的advice。Default...

org.aopalliance.intercept.Joinpoint 顶层接口表示一个运行时的连接点，For instance, an* invocation is the runtime joinpoint on a method (static joinpoint)proceed（） ：Proceed to the next interceptor in the chainorg.aopalliance.intercept.Invocation一个invocat...

JdkDynamicAopProxy 属性AdvisedSupport ，它是aop 代理的配置。当我们创建代理的时候会将config传递进去。JdkDynamicAopProxy 获取代理：生成jdk原生动态代理对象，同时将自己传递进去，实现了InvocationHandler的接口，@Override public Object getProxy(@Nullable ClassLoader classLoader) { if (logger.isDebugEnabled()) {...

@Test public void test(){ ProxyFactory proxyFactory = new ProxyFactory(); // 可改变target的引用 HotSwappableTargetSource targetSource = new HotSwappableTargetSource(new DemoOne("黄晓明")); proxyFactory.setTargetSource(...

spring 对单例的简单bean（未被代理）解决了循环引用的问题，且spring是通过set方式才能实现，构造器注入是不行的关于多级缓存的问题：https://cloud.tencent.com/developer/article/1497692首先创建原始的bean添加到缓存（此时一级缓存坑定是没有的）添加入到三级缓存，这是一个factorygetEarlyBeanReference SmartInstantiationAwareBeanPostProce...

一个简单的例子：public class DemoMain { public static void main(String[] args) throws Exception { Student student = new Student(); AspectJProxyFactory aspectJProxyFactory = new AspectJProxyFactory(student); aspectJProxyFactory.addA

JointPoint 表示一个正在运行时的一个joinpoint，比如方法的一次执行MethodInvocation 描述的是an invocation to a method。他也是一个joinpoint，可以被method interceptor 拦截。ReflectiveMethodInvocation 也是表示方法的执行，通过反射的方式调动目标方法。通过反射的方式执行joinpoint即目标的方法（spring只支持方法）protected Object invokeJo...
