导入log4j的jar包
-
在web.xml上配置如下：
<!-- 配置log4j begin --> <context-param> <param-name>webAppRootKey</param-name> <param-value>bjgjqrcode.root</param-value> <!-- .root --> </context-param> <context-param> <param-name>log4jConfigLocation</param-name> <param-value>WEB-INF/log4j.properties</param-value> <!-- 配置文件存放路径 --> </context-param> <listener> <listener-class> org.springframework.web.util.Log4jConfigListener </listener-class> </listener> <!-- 配置log4j end --> |
3. log4j.properties 文件配置如下：
