SpringBoot程序启动报错：FileNotFoundException：class path resource [***] cannot be opened because it does not exist

SpringBoot项目，启动程序ApiApplication。好好的一个程序，今天在启动程序时发现报错。

Application run failed
org.springframework.beans.factory.BeanDefinitionStoreException: Failed to parse configuration class [com.emax.channel.webapp.ApiApplication]; nested exception is java.io.FileNotFoundException: class path resource [org/apache/ibatis/plugin/Interceptor.class] cannot be opened because it does not exist

这是个老生常谈的错误，既然是org/apache/ibatis/plugin/Interceptor.class，就是缺少apache相关jar包（或其他定义了package为org.apache.ibatis.plugin的jar包）依赖。

执行mvn：clean install了一下，发现并无卵用，问题依然存在。
同样的程序，同事电脑上可以正常启动。
那看来还是跟本地jar包依赖有关。然后，沿着这个思路，把相关jar重新install一下。发现还是没解决。
我开始把焦点放在异常堆栈上，试图从stacktrace寻找一些线索，却也吃了闭门羹，没发现什么有价值的东西。

我就把异常message里提到的 Interceptor ，去相关依赖工程里去查找。 不经意发现，自己曾经在本地测试时，添加了一个实现了Interceptor的MybatisInterceptor类。 罪魁祸首就是这个MybatisInterceptor，把它去掉就好了。不禁又想起了郭德纲于谦早年的相声《羊上树》。。
