If I disable AspectJ, then the getters/setters are appropriately generated. My guess is that the ajc compiler is not able to recognize lombok. Are Lombok and AspectJ mutually exclusive? Can I not use both technologies together? 回答1: The current answer according to AspectJ maintainer Andy Clement is that there are problems due to ECJ (Eclipse Compiler for Java) packages being included and renamed in the

Following is my aspect: @Configurable @Aspect public class TimingAspect { @Autowired private HttpServletRequest httpServletRequest; // Generic performance logger for any mothod private Object logPerfomanceInfo(ProceedingJoinPoint joinPoint, String remoteAddress) { StringBuilder tag = new StringBuilder(); if (joinPoint.getTarget() != null) { tag.append(joinPoint.getTarget().getClass().getName()); tag.append("."); } tag.append(joinPoint.getSignature().getName()); StopWatch stopWatch = new StopWatch(tag.toString()); Object result = joinPoint.proceed(); // continue on the intercepted method

This dependency contains a @org.aspectj.lang.annotation.Aspect class (lets say, com.aspectprovider.aspects.MyAspect ). There's a @Before advice to weave a method from classes that implements the interface Foo . Something like: @Before("execution(* com.project.Foo.save(..))") The Foo interface can be inside the "project" or in another jar. It doesn't matter for this example. My project contains classes that implements Foo . Those are the classes that

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 aspect to capture the

我们使用Spring的AOP功能的时候发现，我们使用普通的配置方式的时候，我们无法精确的确定将切面类中的哪个方法切入到哪个切入点上， 所以我们可以使用aop的专用标签来完成相关的配置.其中主要表现是使用AspectJ的expression的操作 aop:config标签 使用aop的专用标签来完成相关的配置.其中主要表现是使用AspectJ的expression的操作: 　　　　　　修改模式 　　　　　 类型 　　　　说明式 　　　　　　 名称模式(参数模式) execution(modifiers-pattern ret-type-pattern declaring-type-pattern name-pattern(param-pattern) 抛出模式 throws-pattern)除了返回类型模式,名字模式和参数模式以外,所有的部分都是可选的。 返回类型模式决定了方法的返回类型必须依次匹配一个连接点。 你会使用的最频繁的返回类型模式是 *,它代表了匹配任意的返回类型。 一个全称限定的类型名将只会匹配返回给定类型的方法。 名字模式匹配的是方法名。 你可以使用 * 通配符作为所有或者部分命名模式。 参数模式稍微有点复杂:() 匹配了一个不接受任何参数的方法, 而 (..) 匹配了一个接受任意数量参数的方法(零或者更多)。 模式 (*) 匹配了一个接受一个任何类型的参数的方法。
