error at ::0 formal unbound in pointcut 报错

以下是错误代码：

Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'atithmeticCalculatorImpl' defined in file [D:\EclipseWorkspace\spring-2\bin\com\ltj\spring\aop\impl\AtithmeticCalculatorImpl.class]: Initialization of bean failed; nested exception is java.lang.IllegalArgumentException: error at ::0 formal unbound in pointcut

以下是的切面中的代码：

@Aspect
@Component
public class LogginAspect {
/**
* 定义一个方法，用于声明切面表达式，一般地，该方法中不再需要添加其他的代码
* 
*/
@Pointcut("execution(public int com.ltj.spring.aop.impl.AtithmeticCalculatorImpl.*(..))")
public void declareJoinPointExpression() {
}


@Before("declareJoinPointExpression()")
public void beforeMethed(JoinPoint joinPoint) {
String methedName = joinPoint.getSignature().getName();
