我在其他站点中搜索了Baeldung和MKyong。一切看起来不错，但是我的建议没有执行。我读过某处关于在一个方面有多个切入点的知识，因此我为每个切入点创建了单独的方面，但仍然没有用。我正在尝试进行加载时编织。
我的一个方面类
@Aspect
public class AuditUpdateAspect {
@Before("execution(* com.kable.newsstand.kdsejb.session.KdsSessionUpdate.update*(..))")
public void beforeUpdate(JoinPoint jp) {
System.out.println("Update");
Object o = jp.getArgs()[0];
if (o instanceof Auditable) {
Auditable auditable = (Auditable)o;
auditable.setOsUserName(AuditHelper.getAuditName());
System.out.println("Done");
}
}
}
客户代码
// SessionHelper is a helper class with static methods to get stateless EJBs from JNDI
// getUpdate() returns an instance of KdsSessionUpdateBean which implements the KdsSessionUpdate interface
// updateIssue(Issue issue) is a method in KdsSessionUpdateBean
SessionHelper.getUpdate().updateIssue(issue);
编织发生在下面，您将看到：这是程序启动

这里是对SessionHelper.getUpdate().updateIssue(issue);的呼叫。这是缩写，因为发帖时间太长。

所以看起来好像是在加载时进行了编织，但是两个System.out.println("Update");和System.out.println("Done");没有执行。
编辑：根据要求包含aop.xml。

编辑：MCVE的测试代码

System.exit(0);
}
编辑：用简单代码替换EJB后的输出
