我正在设计Spring AOP，并尝试创建一个简单的方面来跟踪所有方法。这段代码可以正常工作：
@Component
@Aspect
public class TracingAspect {
@Before("execution(* accountSubmit(..))")
public void entering() {
System.out.println("entering method");
}
}
但是如果我要跟踪所有方法，则会收到错误消息：
@Component
@Aspect
public class TracingAspect {
@Before("execution(* *(..))")
public void entering() {
System.out.println("entering method");
}
}
错误：
entering method
entering method
entering method

这不是实际问题，但我想知道此错误的原因是什么？
答案 0 :(得分：1)
Spring AOP的工作原理是通过对类进行子类化为类创建代理，并通过拦截对类的调用来应用方面。您可能已经知道，Java中不允许对最终类进行子类化。因此，您应该从自己的角度排除它们。
如果您正在使用AspectJ，则可以通过编写以下代码来做到这一点：
@Component
@Aspect
public class TracingAspect {
@Before("execution(* *(..)) && !within(is(FinalType))")
public void entering() {
System.out.println("entering method");
}
}

尝试使用此代码
@Aspect
@Configuration
public class TracingAspect {
@Before("execution(* *.*(..))")
public void entering() {
System.out.println("entering method");
}
}
