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

一.前言

在使用xml配置aop，测试AOP时，报错如下：

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]

二. 问题定位

提取有用的报错信息：

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

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

报错显示是loginCheck中方法出错，仔细检查了类中的方法，并没有错误，看网上说是aspectjweaver的jar包未引入导致，检查了一下，引入正常，说明不是jar包的问题，想到可能是配置文件有问题，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，并没有发现什么异常，仔细检查了一遍，发现是切点的名称与切面的引用重复了：

修改切点名称为其他的，启动正常！
