Aspectj with android library

一曲冷凌霜 提交于 2019-12-03 06:28:43
问题 I have a lib that use aspects and is available via maven, now I'm trying to use that lib in an android application. If I include this plug-in in the app gradle file, everything works fine, but my goal is to extract the classpath 'com.uphyca.gradle:gradle-android-aspectj-plugin:0.9.+' and the apply plugin: 'android-aspectj' (required by the plugin) to the my.lib gradle file instead of declaring in my app. Is that possible? app gradle file: classpath 'com.uphyca.gradle:gradle-android-aspectj

Autowired dependency not injected in Aspect in Spring MVC

若如初见. 提交于 2019-12-03 06:18:56
I am not able to @Autowire the Service Layer Instance in Aspect. In Aspect the reference to the @Autowired bean is NULL and it throws NullPointerException . Any help will be much appreciated. I think, I messed up with configuration. Following is my servlet-context.xml : <!-- Activates various annotations to be detected in bean classes --> <context:annotation-config /> <context:spring-configured /> <!-- Scans the classpath of this application for @Components to deploy as beans --> <context:component-scan base-package="xx.yy" /> <!-- an @AspectJ aspect will be interpreted as an aspect by Spring

AspectJ weaving maven modules

问题 I have a project that has multiple maven modules, one of which, contains my aspects. How can I take the aspects and weave multiple maven modules? The documentation for the AspectJ Maven plugin is a little sparse and haven't been able to find many examples. I have tried putting the aspectj plugin in the parent pom but it doesn't seem to apply the advice for the modules underneath it. I also tried specifying the aspectsDirectory property but it didn't seem to have any affect. Perhaps I did it

AspectJ Load time weaver doesn't detect all classes

我的未来我决定 提交于 2019-12-03 05:38:50
I am using Spring's declarative transactions (the @Transactional annotation) in "aspectj" mode. It works in most cases exactly like it should, but for one it doesn't. We can call it Lang (because that's what it's actually called). I have been able to pinpoint the problem to the load time weaver. By turning on debug and verbose logging in aop.xml, it lists all classes being woven. The problematic class Lang is indeed not mentioned in the logs at all. Then I put a breakpoint at the top of Lang , causing Eclipse to suspend the thread when the Lang class is loaded. This breakpoint is hit while the

Spring AOP: “no declaration can be found for element 'aop:config' ”

问题 I've seen that a few instances of this problem have been raised already. However, I am confident that I satisfy the criteria that has been outlined in those solutions. i.e. I'm pretty sure I have the desired jars on my class path + my schemalocation addresses look in order. One solution mentioned that the issue can be caused by having another XML parser on the classpath. I do have dom4j on my classpath but I have removed it to test, and the problem persists. Here's my classpath: <?xml version

Spring(四):面向切面编程AOP

横切关注点:分布于应用中多处的功能 面向切面编程AOP:将横切关注点与业务逻辑相分离 在使用面向切面编程时,仍在一个地方定义通用功能,但是可以通过声明的方式定义这个功能以何种方式在何处应用,而无需修改受影响的类。 横切关注点可以被模块化为特殊的类,这些类被称为切面。 好处 : 每个关注点集中于一处,而不是分散到多处代码中 服务模块更加简洁,因为它们只包含主要关注点的代码,次要关注点被转移到切面中了 1、定义AOP术语 1.1、通知(Advice) 切面的工作被称为通知。 通知定义了切面是什么以及何时使用。 Spring切面可以应用的5种类型的通知: Before——在方法被调用之前调用通知 After——在方法完成之后调用通知,无论方法执行是否成功。 After-returning——在方法成功执行之后调用通知。 After-throwing——在方法抛出异常后调用通知。 Around——通知包裹了被通知的方法,在被通知的方法调用之前和调用之后执行自定义的行为。 1.2、连接点(Joinpoint) 连接点是在应用执行过程中能够插入切面的一个点,这个店可以是调用方法时、抛出异常时、甚至修改一个字段时。 1.3、切点(Pointcut) 切点有助于缩小切面所通知连接点的范围,切点的定义会匹配通知所要织入的一个或多个连接点。通常使用明确的类名和方法名来指定这些切点

Spring和事务的关系 关系型数据库、某些消息队列等产品或中间件称为事务性资源,因为它们本身支持事务,也能够处理事务。 Spring很显然不是事务性资源,但是它可以管理事务性资源,所以Spring和事务之间是管理关系。 就像Jack Ma虽然不会写代码,但是他却管理者一大批会写代码的码农。 如果想学习Java工程化、高性能及分布式、深入浅出。微服务、Spring,MyBatis,Netty源码分析的朋友可以加我的Java高级交流:787707172,群里有阿里大牛直播讲解技术,以及Java大型互联网技术的视频免费分享给大家。 Spring事务三要素 数据源:表示具体的事务性资源,是事务的真正处理者,如MySQL等。 事务管理器:像一个大管家,从整体上管理事务的处理过程,如打开、提交、回滚等。 事务应用和属性配置:像一个标识符,表明哪些方法要参与事务,如何参与事务,以及一些相关属性如隔离级别、超时时间等。 Spring事务的注解配置 把一个DataSource(如DruidDataSource)作为一个@Bean注册到Spring容器中,配置好事务性资源。 把一个@EnableTransactionManagement注解放到一个@Configuration类上,配置好事务管理器,并启用事务管理。 把一个@Transactional注解放到类上或方法上,可以设置注解的属性

Does Spring AOP do compile time weaving or load time weaving?

我怕爱的太早我们不能终老 提交于 2019-12-03 03:23:52
I am starting to use Spring AOP for a project and I am a little bit confused about weaving. I know that Spring AOP has a dependency on AspectJweaver.jar, but as the documentation says, this is not for the weaving, but just that it uses some of the classes from this jar. But my question is, if it is not using AspectJ for weaving, does Spring AOP have its own weaving and is it performed at load time or compile time? The relevant part of my Spring Configuration XML file is: <context:annotation-config /> <tx:advice id="txAdvice" transaction-manager="transactionManager"> <tx:attributes> <tx:method

Turan. public class Test { private class InnerTest { public InnerTest() { JButton j = new JButton("button"); j.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { //do something } }); } } } 回答1: You can use the within or withincode pointcuts to match the containing class, and the cflow pointcut to match the execution of the addActionListener() method, then combine that with an execute pointcut to match the

How to configure load-time weaving with AspectJ and Tomcat?

别来无恙 提交于 2019-12-03 03:08:54
I tried to configure load-time weaving (for doing profiling with Perf4J) in the next way: 1) I added aop.xml to META-INF folder. When deployed, META-INF is placed in the artifact root directory (i.e. MyAppDeployed/META-INF ). 2) I put aspectjrt-1.6.1.jar , aspectjweaver-1.6.1.jar , commons-jexl-1.1.jar , commons-logging.jar to the Tomcat/lib folder (at first I tried MyAppDeployed/WEB-INF/libs but it also didn't work). 3) I added -javaagent:C:\apache-tomcat-6.0.33\lib\aspectjweaver-1.6.1.jar to VM options when starting Tomcat. 4) My aop.xml : <!DOCTYPE aspectj PUBLIC "-//AspectJ//DTD//EN" "http
