Spring AOP報錯：Unable to locate method [xxx] on bean [xxx]

一.前言

在使用xml配置aop，測試AOP時，報錯如下：

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name '(inner bean)#3bbc39f8': Initialization of bean failed; nested exception is java.lang.IllegalArgumentException: Unable to locate method [loginBefore] on bean [loginCheck]
	at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.doCreateBean(AbstractAutowireCapableBeanFactory.java:603)

二. 問題定位

提取有用的報錯信息：

Error creating bean with name '(inner bean)#400cff1a'

Unable to locate method [loginBefore] on bean [loginCheck]

報錯顯示是loginCheck中方法出錯，仔細檢查了類中的方法，並沒有錯誤，看網上說是aspectjweaver的jar包未引入導致，檢查了一下，引入正常，說明不是jar包的問題，想到可能是配置文件有問題，我的配置如下;

   <aop:config >
       <aop:aspect id="myLoginCheck" ref="loginCheck">
           <aop:pointcut id="loginCheck" expression="execution(* com.clguo.service.*.*(..))"/>
            <aop:before pointcut-ref="loginCheck" method="loginBefore"/>
        </aop:aspect>
    </aop:config>

大致看了一下，並沒有發現什麼異常，仔細檢查了一遍，發現是切點的名稱與切面的引用重複了：

修改切點名稱爲其他的，啓動正常！
