写在前面
时间断断续续,这次写一点关于spring aop拦截器链的记载。至于如何获取spring的拦截器,前一篇博客已经写的很清楚(spring---aop(2)---Spring AOP的JDK动态代理)
获取拦截器链
final class JdkDynamicAopProxy implements AopProxy, InvocationHandler, Serializable { public Object invoke(Object proxy, Method method, Object[] args) throws Throwable { ... //获取拦截器链 List<Object> chain = this.advised.getInterceptorsAndDynamicInterceptionAdvice(method, targetClass); // Check whether we have any advice. If we don‘t, we can fallback on direct if (chain.isEmpty()) { // 如果拦截器链为空,则执行目标方法 retVal = AopUtils.invokeJoinpointUsingReflection(target, method, args); } else { // 封装拦截器链的执行方法 invocation = new ReflectiveMethodInvocation(proxy, target, method, args, targetClass, chain); // 拦截器链执行 retVal = invocation.proceed(); } ... }
