@AspectJ. Pointcut for scala (and probably java) lambdas

由 穿精又带淫゛_ 提交于 2019-12-10 10:54:00
问题 Is it possible to have poitcut for scala lambdas? If I'm not mistaken scala lambdas now compiled in the same way as java lambdas, so I think my question is also applicable for java lambdas, but I'm not sure. Here is the code. Basically I want to advice Runnable instances. And it works perfectly if I use classes or anonymous class, but it doesn't work if I use lambdas. @Around("execution(* (com.test..* && java.lang.Runnable+).run())") def runnableAspect(pjp: ProceedingJoinPoint): Any = {

Let eclipse use maven to compile/weave my code

由 自闭症网瘾萝莉.ら 提交于 2019-12-10 10:03:35
问题 I am using compile time weaving with aspectj to weave in Spring's transactional code so I can use @Transactional . When i run maven compile from inside Eclipse (which uses the aspectj-maven-plugin), eclipse synchronizes to the tomcat server and all goes well. But when Eclipse compiles (project->build automatically) it appears not to weave the spring transactional code and I get this error: javax.persistence.TransactionRequiredException: no transaction is in progress This is very annoying

spring AspectJ的Execution表达式

由 杀马特。学长 韩版系。学妹 提交于 2019-12-10 07:16:49
Aspectj切入点语法定义 在使用spring框架配置AOP的时候，不管是通过XML配置文件还是注解的方式都需要定义pointcut"切入点" 例如定义切入点表达式 execution (* com.sample.service.impl..*.*(..)) execution()是最常用的切点函数，其语法如下所示： 整个表达式可以分为五个部分： 1、execution(): 表达式主体。 2、第一个*号：表示返回类型，*号表示所有的类型。 3、包名：表示需要拦截的包名，后面的两个句点表示当前包和当前包的所有子包，com.sample.service.impl包、子孙包下所有类的方法。 4、第二个*号：表示类名，*号表示所有的类。 5、*(..):最后这个星号表示方法名，*号表示所有的方法，后面括弧里面表示方法的参数，两个句点表示任何参数。 AspectJ的Execution表达式 execution() execution()是最常用的切点函数，其语法如下所示： execution(<修饰符模式>? <返回类型模式> <方法名模式>(<参数模式>) <异常模式>?) 除了返回类型模式、方法名模式和参数模式外，其它项都是可选的。与其直接讲解该方法的使用规则，还不如通过一个个具体的例子进行理解。下面，我们给出各种使用execution()函数实例。 1)通过方法签名定义切点

Running JDK8 for aspectj

由 梦想与她 提交于 2019-12-10 03:54:03
问题 I am trying to run aspectj-maven plugin with JDK8. But it is giving errors like "The type java.lang.CharSequence cannot be resolved. It is indirectly referenced from required .class files" Any help on how to resolve, or if the aspectj-maven-plugin supports JDK8. I am using 1.6 version of aspectj--maven-plugin. 回答1: I had to achieve the same and I drove crazy trying to figure out this, fortunately I could solve it and here I give you what I did: To use aspectj-maven-plugin with Java 8 you need

Disabling certain aspects during unit test runs

由 橙三吉。 提交于 2019-12-10 01:28:29
问题 I have integration tests (load context) and unit tests running together. My code does aspectj compile time weaving using spring. My problem is that my declared advises also run during some of my unit tests. This kills the notion of a unit test, which is why I would like to disable them. Is there something I can put on the pointcut declaration, some method I can call, some spring configuration, or maven command that disables these advises for something like all *UnitTest.java? Thanks for the

Does a set() field pointcut get invoked if field is set via reflection?

由 匆匆过客 提交于 2019-12-09 23:02:40
问题 I have a field set pointcut, which seems to do as I expect. Its defined as follows before(Object newval): set(@Serviced private * *.*) && args(newval) The above is meant to capture: whenever a private field attribute, annotated with @Serviced, is set call my before advice. Everything seems to work fine, except for the one case in my code that sets a variable matching the above via java reflection ( ie via java.lang.reflect.Field.set(....). Any idea's how I can catch that "set" also? Thanks

Dynamic values are not supported as attributes in annotation- AspectJ Android [AOP Android]

问题 I am using custom annotation to log the id which user clicked. But I am getting a error " Attribute value must be a constant ". My code snippet is below. mAssetId= Asset.getContentId(); @TrackEvent("track_event") @ArrayParams({@Params(key = "content_id",value = mAssetId)}) protected void attributeMethod() { } Thanks in advance. Is there any way to pass dynamic values in annotation rather than static variables or constants. I am using AspectJ library for android. 回答1: It's not possible to

基于Aspectj表达式配置的Spring AOP

由 风格不统一 提交于 2019-12-09 21:01:54
AOP(Aspect-Oriented Programming, 面向切面编程):是一种新的方法论, 是对传统OOP(Object-Oriented Programming, 面向对象编程)的补充。 它其实就是将公共的东西收取出来进行处理，横向重复，纵向抽取。从而使得代码更简洁。 我的博客地址： https://www.cnblogs.com/themysteryofhackers/p/12013351.html 更新时间：2019-12-09 一、创建Maven项目 创建Maven项目的步骤和我上一篇博客的步骤差不多，这里就不再论述了，如果不记得的话，点击这里 如何创建Maven项目 。 创建好Maven项目后，就直接创建包和类。 二、添加项目依赖 因为要用到Spring中的AOP技术，所以要导入Spring的依赖，又因为要用到单元测试，所以也要导入Junit的依赖。 <? xml version="1.0" encoding="UTF-8" ?> < project xmlns = "http://maven.apache.org/POM/4.0.0" xmlns : xsi = "http://www.w3.org/2001/XMLSchema-instance" xsi : schemaLocation = "http://maven.apache.org/POM/4.0

aspectj for Android studio - where is AJDT plugin

由 我是研究僧i 提交于 2019-12-09 19:05:05
问题 How do i install AJDT for android studio. I know there is one for eclipse but i cant find anything in android studio. What i would like to do is run security checks on every one of my method calls before they launch. I've tried from this site AJDT but this is for eclipse. 回答1: Android Studio is an Android-aware version of IntelliJ. IntelliJ has no tooling support for AspectJ. There are two solutions that I can think of: Use Eclipse and ADT, but you probably don't want to do that. Use

AspectJ & Maven warning: “Advice defined in … has not been applied?”
