java.lang.IllegalArgumentException：此类型名称的警告不匹配：ru.sbt.filial.cards.aspect.SomeBean [Xlint：invalidAbsoluteTypeName]

Question

我从来没有使用Spring AOP并尝试配置我的第一个bean。似乎我正确地配置了它，但是我得到了一个异常，发现这个bean没有找到。

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没有发现是 -

package ru.sbt.filial.cards.aspect; 

import org.springframework.stereotype.Component; 

@Component 
public class SomeBean { 

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

} 

我有以下异常 -

我有遵循maven依赖关系 -

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

       <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/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配置线

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

但还是同样的信息。我也试图诠释不同的方式 - 如果我不指定bean即写 -

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

代替

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

我对装载没有错误，但不调用AOP方法。

我也试图诠释这样

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

但同样的结果 - 敌不过这种类型的名称。还有什么想法？

Answer 1

要成功运行，在你的applicationContext.xml春天配置文件中加

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

当你使用SomeBean类@Component注释

更新：

尝试通过添加方法名@Before ：

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

Answer 2

我有同样的pr你和我解决了我的问题。我给你两个建议，你可以试试看。 请修改切面类中@Before注解为以下之一：

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

或

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

希望它能帮助。
