java.lang.IllegalArgumentException：此類型名稱的警告不匹配：ru.sbt.filial.cards.aspect.SomeBean [Xlint：invalidAbsoluteTypeName]

Question

我從來沒有使用Spring AOP並嘗試配置我的第一個bean。似乎我正確地配置了它，但是我得到了一個異常，發現這個bean沒有找到。

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("******"); 
    } 
} 

我的豆是AOP沒有發現是 -

package ru.sbt.filial.cards.aspect; 

import org.springframework.stereotype.Component; 

@Component 
public class SomeBean { 

    public void printSmth() { 
     System.out.println("!!!!!!!!!!!"); 
    } 

} 

我有以下異常 -

我有遵循maven依賴關係 -

   <dependency> 
       <groupId>org.springframework</groupId> 
       <artifactId>spring-aop</artifactId> 
       <version>3.2.0.RELEASE</version> 
       </dependency> 
       <dependency> 
       <groupId>org.aspectj</groupId> 
       <artifactId>aspectjweaver</artifactId> 
       <version>1.7.3</version> 
       </dependency> 
       <dependency> 
       <groupId>org.aspectj</groupId> 
       <artifactId>aspectjrt</artifactId> 
       <version>1.7.3</version> 
       </dependency> 

我的春天的applicationContext.xml配置 -

<?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" 
    xmlns:aop="http://www.springframework.org/schema/aop" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="http://www.springframework.org/schema/beans 
         http://www.springframework.org/schema/beans/spring-beans.xsd 
         http://www.springframework.org/schema/mvc 
       http://www.springframework.org/schema/mvc/spring-mvc.xsd 
         http://www.springframework.org/schema/context 
       http://www.springframework.org/schema/context/spring-context-3.2.xsd 
         http://www.springframework.org/schema/aop 
       http://www.springframework.org/schema/aop/spring-aop-3.0.xsd"> 

<mvc:annotation-driven/> 
<aop:aspectj-autoproxy/> 

<bean id="someBean" class="ru.sbt.filial.cards.aspect.SomeBean"> 
</bean> 

UPDATE 我加入到我的Spring配置線

<context:component-scan base-package="ru.sbt.filial.cards.aspect"/> 

但還是同樣的信息。我也試圖詮釋不同的方式 - 如果我不指定bean即寫 -

@Before("execution(* ru.sbt.filial.cards.aspect.*.*(..))") 

代替

@Before("execution(* ru.sbt.filial.cards.aspect.SomeBean.*(..))") 

我對裝載沒有錯誤，但不調用AOP方法。

我也試圖詮釋這樣

@Before("this(ru.sbt.filial.cards.aspect.SomeBean) and execution(* printSmth(..))") 

但同樣的結果 - 敵不過這種類型的名稱。還有什麼想法？

Answer 1

要成功運行，在你的applicationContext.xml春天配置文件中加

<context:component-scan base-package="ru.sbt.filial.cards.aspect"/> 

當你使用SomeBean類@Component註釋

更新：

嘗試通過添加方法名@Before ：

@Before("execution(* ru.sbt.filial.cards.aspect.SomeBean.logBefore(..))") 

Answer 2

我有同樣的pr你和我解決了我的問題。我給你兩個建議，你可以試試看。 請修改切面類中@Before註解爲以下之一：

@Before("execution(* ru.sbt.filial.cards.aspect.SomeBean.logBefore(..))")

或

@Before("execution(* ru.sbt.filial.cards.aspect.SomeBean..*(..))")

希望它能幫助。
