使用SpringBoot集成Log4j2报错：
WARN The Logger org.springframework.boot.bind.PropertiesConfigurationFactory was created with the message factory org.apache.logging.log4j.spi.MessageFactory2Adapter@47dab94f and is now requested with a null message factory (defaults to org.apache.logging.log4j.message.ParameterizedMessageFactory), which may create log events with unexpected formatting.
springboot版本：1.4.7
log4j2版本：2.6
查了下，这个是log4j2版本2.6的bug，把它升级到2.6.1就可以解决。bug相关信息查看：Misleading WARN log events from Log4j about message factories and unexpected formatting
