问题 Suppose I want to find all classes annotated with @Controller, I would create this pointcut: @Pointcut("within(@org.springframework.stereotype.Controller *)") public void controllerPointcut() {} But those controllers annotated with @RestController can not be found. Since RestController itself is annoatated with @Controller. Any idea on how to find classes annotated either with @Controller or @RestController without having to create two Pointcuts ? ===== edit ==== My real intention here is as

问题 I'm a newbie to AspectJ and Maven. I'm trying to use aspectj-maven-plugin to build my project, but it does not work. I just followed the steps in AspectJ In Action 2 nd Edition . <build> <plugins> <plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>aspectj-maven-plugin</artifactId> <executions> <execution> <goals> <goal>compile</goal> <goal>test-compile</goal> </goals> <configuration> <source>1.5</source> <target>1.5</target> </configuration> </execution> </executions> </plugin> <

问题 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

问题 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

问题 I understand Spring avoids using the -javaagent vm option in order to get its AspectJ load time weaving to work and relies instead on a classloader to start the agent. I thought that the Java specification dictated that the only way to use a Java agent was through the -javaagent vm option. Am I wrong? Can someone please direct me to the official Java specification/documentation that would clarify my interrogation? 回答1: I found some information about loading java agents in this interesting

问题 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

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 11 months ago . I am working with Spring 3.0 framework and still a novice. Can anyone explain me in layman terms what is AOP programming? (a short example will definitely help) How does Spring incorporate/enhance/support it? 回答1: AOP is a way to modify existing classes in a code base to
