pointcut

8.2.3 Declaring a pointcut Recall that pointcuts determine join points of interest, and thus enable us to control when advice executes. Spring AOP only supports method execution join points for Spring beans , so you can think of a pointcut as matching the execution of methods on Spring beans. A pointcut declaration has two parts: a signature comprising a name and any parameters, and a pointcut expression that determines exactly which method executions we are interested in. Spring AOP 仅仅支持Bean里面的方法切入点，所以切入点主要作用就是申明 匹配 Bean里面的方法。Pointcut 申明有两个部分哦，一个是签名方法 包含有方法名字和参数。另外一个是切入点表达式，这个是用来申明在哪些方法上面执行切入

I am able to get the signature and arguments from advised method calls, but I cannot figure out how to get the return values or exceptions. I'm kind of assuming that it can be done in some way using around and proceed. You can use after() returning and after() throwing advices as in beginning of the following document . If you're using @AspectJ syntax please refer to @AfterReturning and @AfterThrowing annotations (you can find samples here ). You can also get return value using after returing advice. package com.eos.poc.test; public class AOPDemo { public static void main(String[] args) {

I have within aspectJ the expression: @Pointcut("within(com.param.cpms.dao.impl.ProjectMetaDaoImpl)") public void daoExceptionHandle() { } At Spring 3.0 startup, I am getting the following error : nested exception is java.lang.IllegalArgumentException: error at ::0 formal unbound in pointcut Probably the problem is not in your pointcut, but in an advice using that pointcut and using a parameter which does not exist in the pointcut. Just remove the parameter from the advice (well, or add it to the pointcut). The post is rather old, but for the sake of completeness I am adding another reason, if

I have a class that looks like follows (from Spring Roo DataOnDemand) which returns a new transient (not persisted) object for use in unit testing. This is what the code looks like after we do a push-in from Spring Roo's ITD. public class MyObjectOnDemand { public MyObjectOnDemand getNewTransientObject(int index) { MyObjectOnDemand obj = new MyObjectOnDemand(); return obj; } } What I need to do is make additional calls on the returned object reference to set additional fields that Spring Roo's auto-generated method is not taking care of. So without modifying the above code (or pushing it in

Given the following example classes in my.package ... public class Foo { public void logicNotInBar() {/*code*/} public void logicBarOverrides() {/*code*/} } public class Bar extends Foo { public void logicBarOverrides() {/*code*/} } and the following Spring-AOP pointcuts... <aop:pointcut id="myPointcutAll" expression="execution(* my.package.*.*(..))" /> <aop:pointcut id="myPointcutFoo" expression="execution(* my.package.Foo.*(..))" /> <aop:pointcut id="myPointcutBar" expression="execution(* my.package.Bar.*(..))" /> What is the result of advice applied to the above pointcuts on instances of

I need to inject few methods to every initialized object using AspectJ. I thought using this : pointcut vistaInjection(Object o) : initialization(java.lang.Object.new() ) && target(o) && !within(objectAspect); before(Object o): methodInjection(o){System.err.println("INIT");} to pointcut initialization of object, so I can inject these methods directly into the object that is part of every other object. However, it does't work. Do you have any idea why? Or what may be an other way how to make 100% sure that every single initialized object will be pointcut? *.new does not work for stuff such
