AOP中的通知调用流程

—递归+调用链模式–
this.currentInterceptorIndex
**=========-1 入口**
public Object proceed() throws Throwable {
if (this.currentInterceptorIndex == this.interceptorsAndDynamicMethodMatchers.size() - 1) {
return invokeJoinpoint();
}
Object interceptorOrInterceptionAdvice =this.interceptorsAndDynamicMethodMatchers.get(++this.currentInterceptorIndex);
。。
return ((MethodInterceptor) interceptorOrInterceptionAdvice).invoke(this);
}
-0暴露通知 org.springframework.aop.interceptor.ExposeInvocationInterceptor#invoke
@Override
public Object invoke(MethodInvocation mi) throws Throwable {
MethodInvocation oldInvocation = invocation.get();
invocation.set(mi);
try {
return mi.proceed();
}
finally {
invocation.set(oldInvocation);
}
}
–1异常通知 org.springframework.aop.aspectj.AspectJAfterThrowingAdvice#invoke
@Override
public Object invoke(MethodInvocation mi) throws Throwable {
try {
return mi.proceed();
}
catch (Throwable ex) {
if (shouldInvokeOnThrowing(ex)) {
invokeAdviceMethod(getJoinPointMatch(), null, ex);
}
throw ex;
}
}
—2返回通知 org.springframework.aop.framework.adapter.AfterReturningAdviceInterceptor#invoke
@Override
public Object invoke(MethodInvocation mi) throws Throwable {
Object retVal = mi.proceed();
this.advice.afterReturning(retVal, mi.getMethod(), mi.getArguments(), mi.getThis());
return retVal;
}
----3后置通知org.springframework.aop.aspectj.AspectJAfterAdvice#invoke
@Override
public Object invoke(MethodInvocation mi) throws Throwable {
try {
return mi.proceed();
}
finally {
invokeAdviceMethod(getJoinPointMatch(), null, null);
}
}
-----4前置通知 org.springframework.aop.framework.adapter.MethodBeforeAdviceInterceptor#invoke
@Override
public Object invoke(MethodInvocation mi) throws Throwable {
this.advice.before(mi.getMethod(), mi.getArguments(), mi.getThis());
return mi.proceed();
}
