java.lang.IllegalArgumentException: warning no match for this type name: ru.sbt.filial.cards.aspect.SomeBean [Xlint:invalidAbsoluteTypeName]

我从未使用过Spring AOP并尝试配置我的第一个Bean。似乎我正确配置了它,但是我得到了一个例外,即找不到bean。
我的方面是 -
@Aspect
@Component
public class IdentificationAspect {
@Before("execution(* ru.sbt.filial.cards.aspect.SomeBean.*(..))")
public void logBefore(JoinPoint joinPoint) throws Throwable {
System.out.println("logBefore() is running!");
System.out.println("hijacked : " + joinPoint.getSignature().getName());
System.out.println("******");
}
}
而AOP找不到的我的豆子是——
package ru.sbt.filial.cards.aspect;
import org.springframework.stereotype.Component;
@Component
public class SomeBean {
public void printSmth() {
System.out.println("!!!!!!!!!!!");
}
}
我有以下例外 -

而我的弹簧应用Context.xml配置是-
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:mvc="http://www.springframework.org/schema/mvc"

<bean id="someBean" class="ru.sbt.filial.cards.aspect.SomeBean">
</bean>
更新我添加到我的弹簧配置线
<context:component-scan base-package="ru.sbt.filial.cards.aspect"/>
但仍然是相同的信息。我还尝试以不同的方式注释 - 如果我不指定豆子,即写 -
@Before("execution(* ru.sbt.filial.cards.aspect.*.*(..))")
相反
@Before("execution(* ru.sbt.filial.cards.aspect.SomeBean.*(..))")
我在加载时没有错误,但未调用aop方法。
我也尝试像这样注释
@Before("this(ru.sbt.filial.cards.aspect.SomeBean) and execution(* printSmth(..))")
但具有相同的结果 - 此类型名称不匹配。还有更多的想法吗??
