通过排查，大概问题出现在配置事务处
 <aop:config> <aop:advisor advice-ref="txAdvice" pointcut="execution(* com..*.*(..))"></aop:advisor> </aop:config>
在和学习视频对照后发现aspect表达式和视频内容有所不同，后面改了一下，发现了问题所在，原来是我的理解有误，我原以为包名与类名之间的两点代表该包及其以下的所有包比如之前我的表达式为"execution(* com..*.*(..))"
我的文件结构
按照我之前的理解，我以为这样的表达式能指向com包下的所有类
实际上，包名和类名之间的两点代表该包及其子包下的类，并不包括子包的子包所有，将以上表达式改为"execution(* com.she..*.*(..))"程序不再报错
