is it possible to make a @Aspect request scope in spring

问题 is it possible to make a @Aspect request scope in spring? Because it seems that it doesn't work, and it kind of makes sense; the proxy object isn't actually injected anywhere, the advice is just applied by the runtime. Just wondering... Example: @Aspect public class MyAspect { // expecting this to get autowired per request @Autowired private HttpServletRequest request; @Around(...) public void doSomething(ProceedingJoinPoint pjp) { // something here pjp.proceed(); // something there } } And

问题 I want to integrate in Android project on Gradle following libraries: Lombok RoboBinding with AspectJ Dagger In order to use RoboBinding with AspectJ and android tools 1.1.0 I compiled aspectj-plugin with this fix. All libraries are using some compile time annotation processing. I found that Lombok isn't compatible with AspectJ. I noticed that annotation processor from RoboBinding is using apt whereas lombok works only with provided (Dagger works with both). I found also Lombok and AspectJ

Aspect weaving at runtime

阅读更多关于 Aspect weaving at runtime

问题 I'm looking for a Java solution that would allow me to use AOP to weave new code on top of already running code at runtime. The key is not to require the restart of the JVM. Also, I'd like to remove the woven at runtime, leaving the old code running the way it was before weaving. I'm thinking AspectJ load time weaving + runtime class loading/unloading would do it. Has anyone tried it? Any recommendations? Thank you. 回答1: A few things to consider: True, you can do LTW during class loading, but

spring ioc和aop的含义

阅读更多关于 spring ioc和aop的含义

自己整理的一些笔记，如有错误欢迎提出指正，谢谢 1.IOC的定义？ IOC：另外一种说法叫DI（Dependency Injection），即依赖注入,是一种设计思想。我们通过IOC将相互依赖对象的创建、协调工作交给Spring容器去处理，每个对象只需要关注其自身的业务逻辑关系就可以了。作用是为了解耦，降低类之间的耦合度，其设计思想就是设计模式的工厂模式，我们并不需要知道其生产的具体过程，我们只要其产出的对象即可。其工作流程就是：在Spring容器启动的时候，Spring会把你在application.xml中配置好的bean都初始化，在你需要调用的时候，把已经初始化的bean分配给你要调用这些bean的类，而不用去创建一个对象的实例。 2.IOC的传值方式有哪些？一般的是设值传入和构造方法传入。 3.IOC的容器有哪些？常见的一般是ApplicationContext和BeanFactory,这两个容器的区别请看这里： http://blog.csdn.net/hi_kevin/article/details/7325554 4.依赖注入的实现方式就是Java的反射，通俗的来讲就是根据给出的类名来动态地生成对象，用set方法将事先保存在hashmap中的类属性注入到类中。 AOP：面向切面编程，被定义为促使软件系统实现关注点的分离的技术。

问题 I am working with AspectJ at the moment. I seperated AspectJ code in a dependency. Within that dependency everything works as intended. But as soon as I import it in another project only some functionality does not work anymore. When using the defaultImpl of @DeclareParents, the interface is shown within the compiled code but not the default Implementation. Here is my code to show what I mean (every code snippet is its own File): AspectJ code: public interface IAspect { String hello(); }

Aspectj里边的aop操作

（1）切入点：在类里边可以有很多方法被增强，比如实际操作中，只是增强了类里边的add方法和update方法，实际增强的方法称为切入点。（2）通知/增强：增强的逻辑，称为增强，比如扩展日志功能，这个日志功能称为增强。前置通知：在方法之前执行。后置通知：在方法之后执行。异常通知：方法出现异常。最终通知：在后置之后执行。环绕通知：在方法之前和之后执行。（3）切面：把增强应用到具体方法上边，过程称为切面。把增强用到切入点过程。下边为具体的代码。 1.被增强对象Book package cn.itcast.aop; public class Book { public void add() { System.out.println("add..........."); } } 2.增强对象MyBook package cn.itcast.aop; import org.aspectj.lang.ProceedingJoinPoint; public class MyBook { public void before1() { System.out.println("前置增强......"); } public void after1() { System.out.println("后置增强......"); } //环绕通知 public void around1
