Issue
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
Answer
原因:没有发现Log4j2的配置文件
解决办法:在src\main\resources下,添加一个log4j2.xml的配置文件
