!-- log4j --> < dependency > < groupId >log4j</ groupId > < artifactId >log4j</ artifactId > < version >1.2.17</ version > </ dependency > < dependency > < groupId >org.slf4j</ groupId > < artifactId >slf4j-api</ artifactId > < version >1.7.4</ version > </ dependency > < dependency > < groupId >org.slf4j</ groupId > < artifactId >slf4j-log4j12</ artifactId > < version >1.7.4</ version > < scope >runtime</ scope > </ dependency > |
2、将log4j.properties放入项目src路径下即可,虚拟机会自动加载日志配置文件,文件内容如下:
