aspectj

I wanted to specify a pattern for aspectj @Around aspect that includes multiple packages. Example : package 1 : aaa.bbb.ccc.ddd package 2 : aaa.bbb.ccc.eee package 3 : aaa.bbb.ccc.eee.fff Pattern which i used : @Around("execution(* aaa.bbb.ccc.ddd.*.*(..)) && execution(* aaa.bbb.ccc.eee..*.*(..))") i.e Intercept packages aaa.bbb.ccc.ddd, aaa.bbb.ccc.eee and any sub-package of aaa.bbb.ccc.eee But this pattern doesnt seem to work. Though specifying a single pattern without && condition works. Can someone suggest whats wrong with this pattern? Thanks, Gayathri && stands for logical AND . What You

I work on an legacy application, where Spring AOP (namely ProxyFactoryBean ) is used. I need to add an aspect around a method of a certain class. This class is not a bean however. The AspecjJ pointcut expression would be like this: execution(* xyz.package.Class.method()) I created a MethodInterceptor and AspectJExpressionPointcut , but I don't know how make those two work together. EDIT : I do not have source code for this class, it is a 3rd party library. The instances of this class are not created by me, neither in source code, nor in spring configuration as beans. It is used internally by

I am looking at AspectJ to see if perhaps we can use it in our test suite. We have a rather large third party Java communications library hardwired to use its own classes (which do not implement any interfaces) which in turn mean that we need a physical backend present and correctly configured to be able to run tests. I am looking at our options for removing this restriction. A possibility would be to create a subclass of the troublesome classes and then ask AspectJ to simply replace "new X" with "new OurSubclassOfX" when loading the third party library, but I am new to AspectJ and from my

I have discovered a pattern in my JPA mappings that I would like to codify. A simple example follows: @OneToMany(fetch=FetchType.EAGER) @Sort(type=SortType.NATURAL) private SortedSet<Item> items; I would like to create a single annotation called SortedOneToMany that I can apply to the above set: public @interface SortedOneToMany { FetchType fetch() default EAGER; SortType sort() default NATURAL; Class comparator() default void.class; } I have written the following aspect to "attach" the JPA annotations whenever it sees my annotation: public aspect SortedOneToManyAspect { declare @field:

Does anybody success in using AspectJ load-time weaving with signed jars? I got an exception and have no idea how to fix it (tested with AspectJ 1.6.8-16.10): Exception in thread "main" java.lang.NoClassDefFoundError: com/package/clazz$AjcClosure1 at com.package.test.main(test.java:55) Caused by: java.lang.ClassNotFoundException: com.package.clazz$AjcClosure1 at java.net.URLClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.misc.Launcher

对于像我这种喜欢滥用AOP的程序员,遇到坑也是习惯了,不仅仅是事务,其实只要脱离了Spring容器管理的所有对象,对于SpringAOP的注解都会失效,因为他们不是Spring容器的代理类,SpringAOP,就切入不了 当然可以使用原生ASPECTJ,不用SpringAOP,但是基于生态链问题,还是尽量使用SpringAOP 这里简单说一下,Spring如何选择使用CGLIB,或者是JDK代理, 简单来说,如果实现了某个接口,那么Spring就选择JDK代理(不一定),如果没有,那么就选择CGLIB代理,说起来简单,Spring还会闹脾气,不代理呢 问题引出 一直以来比较多的情况是在Controller 调用Service 的方法,把事务直接在Service的方法上,妥妥的没问题,事务正常执行 考虑以下问题: 同对象的方法B 调用自己的方法A,这里的事务将会失效(严格上来说,只要对方法A使用注解AOP均会失效),原因是因为这里的this.调用的并不是Spring的代理对象 @Service public class ClassA{ @Transactional(propagation = Propagation.REQUIRES_NEW) public void methodA(){ } /** * 这里调用methodA() 的事务将会失效 */ public void

Im trying to use Lombok in combination with AspectJ and Maven. So, what's the problem? When i use the AspectJ Maven Plugin (www.mojohaus.org/aspectj-maven-plugin/), it takes the sources and compiles them and ignores changes made by Lombok. I followed this tutorial and came up with this code and AspectJ works, but Lombok dies with this message: [WARNING] You aren't using a compiler supported by lombok, so lombok will not work and has been disabled. Your processor is: org.aspectj.org.eclipse.jdt.internal.compiler.apt.dispatch.BatchProcessingEnvImpl Lombok supports: sun/apple javac 1.6, ECJ So,
