spring的解释见  https://github.com/spring-projects/spring-boot/issues/9172

Spring Boot 1.5.x isn't compatible with Log4j 2.8.x. We're planning support with Spring Boot 2.0.0 (see #8854).

另在spring-boot和log4j2 搭配使用时，如果log4j2.xml不在根路径下，务必在application.properties里加上

 

logging.config=config/log4j2.xml

config 为log4j2.xml 所在的目录，否则日志里会没有记录
