Question

我在我的EAR项目中使用AspectJ作为AOP API。该项目包含EJB和MBean，并在Wildfly 8.2.0应用程序服务器上运行。

在AspectJ中，有一个方面关联 - perthis我试图在我的项目中实现。此方面关联将为每个关节点的执行对象创建新的方面实例。

详细信息：

AspectJ version used: 1.8.5
EJB version: 3.2
Application server: Wildfly 8.2.0
Java version: 1.7

在使用perthis方面关联时，我收到的一些EJB和MBean的错误如下所示：

Aspectj perthis用法：

@Aspect("perthis(getField2() || setField2())")
public abstract class Field2Aspect {
...
...
}

获得错误：

JFYI我只是在实施perthis实施时才收到错误。由于AspectJ方面关联默认为SINGLETON，我需要在我的项目中实现perthis，并且实现相同的方法会给我上述错误。有没有人遇到这种情况和错误？请帮我。感谢。

使用 percflow 方面关联解决了上述问题。

获取java.lang.ClassFormatError：在Wildfly 8中实现PERTHIS aspectJ实现时，在类文件中复制方法名称和签名
