SpringBoot項目，啟動程序ApiApplication。好好的一個程序，今天在啟動程序時發現報錯。
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
這是個老生常談的錯誤，既然是org/apache/ibatis/plugin/Interceptor.class，就是缺少apache相關jar包（或其他定義了package為org.apache.ibatis.plugin的jar包）依賴。
執行mvn：clean install了一下，發現並無卵用，問題依然存在。
同樣的程序，同事電腦上可以正常啟動。
那看來還是跟本地jar包依賴有關。然后，沿着這個思路，把相關jar重新install一下。發現還是沒解決。
我開始把焦點放在異常堆棧上，試圖從stacktrace尋找一些線索，卻也吃了閉門羹，沒發現什么有價值的東西。

我就把異常message里提到的 Interceptor ，去相關依賴工程里去查找。 不經意發現，自己曾經在本地測試時，添加了一個實現了Interceptor的MybatisInterceptor類。 罪魁禍首就是這個MybatisInterceptor，把它去掉就好了。不禁又想起了郭德綱於謙早年的相聲《羊上樹》。。
