本文详细解析了在使用Spring AOP与AspectJ进行切面编程时遇到的IllegalArgumentException异常，分析了异常原因，包括类名或类路径错误以及表达式书写问题，并提供了两种解决方案：通配切入和精准切入。

1.异常现象

2.排查分析

此类型名称不匹配

参数非法：没有与类型匹配的参数

一般可能是类名、类路径哪里有问题，先确认一下。再就是写法可能哪里有问题。

3.解决方案

3.1.通配切入


@Pointcut("execution(public * com.weix.service..*ServiceImpl.*(..)) " +
       "|| execution(public * com.weix.service..*ManagerImpl.*(..))")
public void point() {
}

3.2.精准切入

@Pointcut("execution(public * com.weix.service.im.impl.LcServiceImpl.sendMsg(..)) " +
       "|| execution(public * com.weix.service.im.impl.TxServiceImpl.sendMsg(..))")
public void sendMsg() {
}
