问题 I annotate my spring boot controller some functions with a custom annotation for logging purpose. However, I find the before advice is executed twice for nested methods. Looking for some idea here. Please refer to the code snippets below. Controller @RequestMapping(value = "apply") @OperationMILog public ApplyHttpResponse apply(@RequestHeader final String custId, @RequestAttribute final String cardNo, @RequestBody final InstallmentApplyHttpRequest installApplyReq, @PathVariable final String

问题 Does anyone know what technique spring uses to achieve dependency injection at runtime? Does it simply use aspects (AOP) or is it something more complicated? 回答1: Spring does a lot of things, but dependency injection itself is actually a surprisingly simple mechanism. It starts with having a registry for classes that are available for injection. Classes that are added to this registry are examined using reflection. A DI framework will look for relevant annotations and constructors to

问题 Description How to create a pointcut for Runnable.run method So that @Before and @After aspect can be invoked in java 8 lambda expression. Create pointcut for Runnable.run method Create @Before aspect for pointcut in step 1 . ---> Print Before runnbale Create @Aefore aspect for pointcut in step 1 . ---> Print After runnable When below line invoked executor.runAsync(() -> { System.out.println("Runnable invoked"); } ) Output expected : Before runnable Runnable invoked After runnable Solution

问题 Every method that called before thread is running, works good, but after starting a thread It doesn't enters aspect. I'm using JDK dynamic proxy objects that implements interface, all public methods called from other thread and not from object itself. I'm using spring 3.0.6. Please help me to understand what I'm missing. Aspect: @Aspect public class CabLoggingAspect { public void init() { System.out.println("CabLoggingAspect: init()"); } @Pointcut("execution(* com.station.taxi.ICab.*(..))")

问题 I'm trying to create a custom attribute that will work in a sort-of AOP way (I don't have access to postsharp, unfortunately and I'm not very familiar with Unity). It has AttributeUsage.Method and in its constructor it configures some parts of the test environment (pulls some info out of app.config and calls some exes that config the environment). It works, except that right now, when I build the solution, the attribute is executed - which is undesireable. Is there a way to create a custom

问题 There is a process called app wrapping: IPA is disassembled (taken apart + sometimes executable part of is is really disassembled) Some new binary code, resources, segments are added IPA is assembled again Quite often this process is used as compile time AOP (to add some aspect like security, audit etc to application). Have you seen any guide + tools which are used for this? 回答1: Here is good overview on app wrapping for iOS: http://pauldotcom.com/wiki/index.php/Episode226#Library_Injection

问题 The question is short and simple: Is there a way to get the Method object from an apsectj ProceedingJoinPoint? Currently I am doing Class[] parameterTypes = new Class[joinPoint.getArgs().length]; Object[] args = joinPoint.getArgs(); for(int i=0; i<args.length; i++) { if(args[i] != null) { parameterTypes[i] = args[i].getClass(); } else { parameterTypes[i] = null; } } String methodName = joinPoint.getSignature().getName(); Method method = joinPoint.getSignature() .getDeclaringType().getMethod
