AspectJ in Maven project, not working/weaving

阅读更多关于 AspectJ in Maven project, not working/weaving

问题 I am trying get the AspectJ weaving working in a simple Maven project, and not sure where it is going wrong : when I run the code using "mvn exec:java", I dont see expected output. I am sure the code is working, because I tried the same in STS, where it works fine. I just wanted to get the AspectJ working in a Maven project. Any hints to how to debug this kind of issues will be much appreciated. <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema

要在 Spring 应用中使用 AspectJ 注解, 必须在 classpath 下包含 AspectJ 类库: aopalliance.jar、aspectj.weaver.jar 和 spring-aspects.jar 将 aop Schema 添加到 <beans> 根元素中. 要在 Spring IOC 容器中启用 AspectJ 注解支持, 只要在 Bean 配置文件中定义一个空的 XML 元素 <aop:aspectj-autoproxy> 当 Spring IOC 容器侦测到 Bean 配置文件中的 <aop:aspectj-autoproxy> 元素时,会自动为与 AspectJ 切面匹配的 Bean 创建代理要在 Spring 中声明 AspectJ 切面,只需要在 IOC 容器中将切面声明为 Bean 实例. 当在 Spring IOC 容器中初始化 AspectJ 切面之后,Spring IOC 容器就会为那些与 AspectJ 切面相匹配的 Bean 创建代理. 在 AspectJ 注解中, 切面只是一个带有 @Aspect 注解的 Java 类. 通知是标注有某种注解的简单的 Java 方法. AspectJ 支持 5 种类型的通知注解: @Before: 前置通知, 在方法执行之前执行 @After: 后置通知, 在方法执行之后执行

问题 I'm trying to get my Spring MVC app to play nice with Spring @Secured annotations and AspectJ auto-proxying but it doesn't seem to be proxying or recognising my @Secured annotations. I have a controller like this: @Controller @RequestMapping("/") public class ApplicationController { private ApplicationFactory applicationFactory; @Inject public ApplicationController(ApplicationFactory applicationFactory) { super(); this.applicationFactory = applicationFactory; } @Secured("ROLE_USER")

问题 According to Spring's Documentation Configuring AspectJ aspects using Spring IoC in order to configure an aspect for Spring IOC, the following has to be added to the xml configuration: <bean id="profiler" class="com.xyz.profiler.Profiler" factory-method="aspectOf"> <property name="profilingStrategy" ref="jamonProfilingStrategy"/> </bean> As suggested by @SotiriosDelimanolis, rewriting this as the following in JavaConfig should to work: @Bean public com.xyz.profiler.Profiler profiler() { com

面向切面编程（aop）

1、AOP的概念： aop采用了横向抽取机制替代了传统地纵向继承体系的重复性代码，不通过过修改源代码可以实现功能的添加 2、AOP的原理：使用动态代理的方式，创建接口实现类的代理类注：使员工jdk的动态代理是针对有接口的情况使用cglib动态代理是针对没有接口的情况，创建某个类子类的代理类 3.AOP的相关术语： 1）JointPoint（连接点）：那些被拦截到的点，主要指方法，因为spring框架中只支持方法类型的连接点，也就是类里面可以被增强的方法 2）PointCut(切入点)：对哪些需要拦截的JointPoint的定义，实际就是类里面实际被增强的方法 3）Advice（通知\增强）：对拦截到的JointPoint所做的事叫做通知，通知分为前置通知，后置通知，环绕通知，异常通知，最终通知（切面需要完成的功能），就是实际添加的功能的逻辑前置通知：方法之前执行后置通知：方法之后执行环绕通知：方法之前之后执行异常通知：方法异常执行最终通知：后置之后执行 4）Aspect（切面）：通知与切入点的结合，把增强具体应用到切入点的过程 5）Introduction(引介):在不修改代码的前提下，在运行期间动态的向类中添加一些属性或者方法 6）Target（目标对象）：代理的目标对象（要增强的类） 7）Weaving（织入）

问题 I have two different aspect classes to count the number of non-static method calls for an execution of a test program. The first aspect counts methods on "call" join points: pointcut methodCalls() : call (!static * test..*(..)); before(): methodCalls() { counter.methodCallCounter(); } while the second aspect counts methods on "execution" join points: pointcut methodCalls() : execution (!static * test..*(..)); before(): methodCalls() { counter.methodCallCounter(); } methodCallCounter() is a

How to use AOP with AspectJ for logging?

问题 I would like to add "trace" messages to all my public methods as follows: public void foo(s:String, n:int) { // log is a log4j logger or any other library log.trace(String.format("Enter foo with s: %s, n: %d", s, n)) ... log.trace("Exit foo") } Now I would like to add all those log.trace to my methods automatically with AOP (and byte code instrumentation). I am thinking about AspectJ . Does it make sense? Do you know any open-source, which does exactly that? 回答1: I have created a simple

Spring AOP（注入AsPectJ切面）

一、介绍 AOP（Aspect Oriented Programming）。区别： OOP（Object Oriented Programming）和AOP（Aspect Oriented Programming）的区别：面向目标的区别，OOP面向名词领域，AOP面向动词领域。思想结构的区别，OOP是纵向结构，AOP是横向结构。注重方面的区别，OOP注重业务逻辑单元的划分，AOP偏重业务处理过程的某个步骤或阶段。 AOP功能： AOP面向切面编程是对OOP面向对象编程的一种补充。对业务逻辑各个部分进行隔离，降低功能之间的耦合度，提高代码复用率。主要的功能是：日志记录，性能统计，安全控制，事务处理，异常处理，权限管理、缓存管理、资源池管理等。 AOP代理： AOP实现的关键是代理模式，AOP代理分为静态代理和动态代理。静态代理指AspectJ，在编译阶段生成AOP代理类，也称编译时增强。动态代理在运行时用JDK动态代理和CGLIB在内存中临时生成AOP代理类，也称为运行时增强。两种动态代理： Spring会使用JDK动态代理只支持实现类（实现了某个接口，委托类）的代理。否则，会使用CGLib来实现动态代理。CGLib动态代理是通过字节码底层继承被代理类（不能被final关键字所修饰）来实现。 CGLIB（Code Generator Library）：是一个强大的
