博客指出使用Idea运行程序时出现报错，经分析是log4j包冲突所致，解决办法是注释掉父类工程的log4j依赖，同时提醒在Maven工程导入依赖时要注意父类和子类间的包冲突问题。

运行程序时，idea报错如下：

ERROR StatusLogger No Log4j 2 configuration file found. Using default configuration (logging only errors to the console), or user programmatically provided configurations. Set system property 'log4j2.debug' to show Log4j 2 internal initialization logging. See https://logging.apache.org/log4j/2.x/manual/configuration.html for instructions on how to configure Log4j 2

报错信息很明显，是log4j的包冲突了，注释掉父类工程的log4j依赖即可。
注意：maven工程导入依赖的时候注意父类和子类之间的包冲突。
