切入点格式不正确

Question

我正在学习spring AOP。在尝试示例时，我收到 "Pointcut is not well-formed" 异常。以下是详细的例外情况：

代码：包裹 org.aspectDemo.aspect.com；

import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.aspectj.lang.annotation.Pointcut;

@Aspect
public class LogginAspect {
    @Before("allGetters()")
    public void LoggingAdvice(){
        System.out.println("Advice run. Get method called");
    }
    @Pointcut("execution(* * org.aspectDemo.model.com.Circle.*())")
    public void allGetters(){}

}

异常：

java.lang.IllegalArgumentException: Pointcut is not well-formed: expecting '(' at character position 14
execution(* * org.aspectDemo.model.com.Circle.*())
            ^^^

根据 the documentation，您似乎多了一个星号。此外，"any arguments" 被编码为 (..) 你的表达式应该是

execution(* org.aspectDemo.model.com.Circle.*(..))
