Question

我正在学习春天的AOP。在尝试一个例子的时候，我得到的是“Pointcut没有格式良好”的例外。以下是例外情况：

代码：包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(){}

}

例外：

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

根据the documentation，你似乎有太多的星号。此外，＆＃34;任何参数＆＃34;编码为(..)您的表达式应为

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

切入点格式不正确
