问题 I'm trying to exclude several methods from log files using aspectj (Im usong spring and Load-time weaving). Is there a way to list the excluded methods in the aop.xml? I know i can do this for full classes but I'm looking for specific methods. or can i make a list in the aspect class? Thanks 回答1: I don't know how to do it in an XML, but it's easy enough to do it in the aspects themselves, as pointcuts can be combined using boolean operators. Traditional aspectj syntax: pointcut

问题 The docs explain that, the LTW has to enabled either through the use of <context:load-time-weaver/> xml instruction or the use of @EnableLoadTimeWeaving annotation. However, I have done neither, but I still see that aspects are woven correctly in my projects! In this case, I don't think they are woven at compile-time (but are they?), so it's surely got to be load-time-weaving? Even if that's the case, how does it automatically choose to weave aspects in during load-time? Shouldn't the aspects

问题 I have a collection of unmanaged classes that I are instantiated outside of Spring. I've been attempting to use Spring AOP with load time weaving to @Autowire a bean into these classes but have so far not had any luck. I've been testing using Tomcat 8 and Spring Boot 1.2.0. My @Configuration where I attempt to set up class looks like this: @Configuration @PropertySource("classpath:application.properties") @EnableSpringConfigured @EnableLoadTimeWeaving public class Config Inside Config I

问题 i am creating an aspect class with spring aspectj as follow @Aspect public class AspectDemo { @Pointcut("execution(* abc.execute(..))") public void executeMethods() { } @Around("executeMethods()") public Object profile(ProceedingJoinPoint pjp) throws Throwable { System.out.println("Going to call the method."); Object output = pjp.proceed(); System.out.println("Method execution completed."); return output; } } now i want to access the property name of class abc then how to acccess it in aspect

问题 I have an application running with Spring, and I'm using AOP in some places. Since I want to use the @Transactional annotation at interface level, I have to allow Spring to create JDK proxies. So, I don't set the proxy-target-class property to true. On the other hand, I don't want to create an interface for every single class I want advised: if the interface just doesn't make sense, I want to have just the implementation, and Spring should create a CGLIB proxy. Everything was working

问题 Upon starting my application, I get numerous warnings along the lines of o.s.aop.framework.Cglib2AopProxy 'Unable to proxy method [public final void org.springframework.jdbc.core.support.JdbcDaoSupport.setDataSource(javax.sql.DataSource)] because it is final: All calls to this method via a proxy will be routed directly to the proxy.' for about a dozen or so functions. Now I perfectly understand that proxy-based aspects cannot be applied to final methods. However, I did not (on purpose, at

问题 Spring docs say: After advice must be prepared to handle both normal and exception return conditions. @After("com.xyz.myapp.SystemArchitecture.dataAccessOperation()") public void doReleaseLock() { // ... } I'm interested in knowing whether dataAccessOperation completed normally or with an exception. Unfortunately, the above code snippet is in the run for the most useless documentation ever produced. I understand that I can use AfterReturning and AfterThrowing separately, or even Around , but
