以前使用log4j，后台可以打印sql日志，现在换成log4j2了，所有日志都不打印了，怎么破
下面是我log4j2.xml的内容

看本站源码的log4j.xml,地址在页脚.

用了你的log4j2.xml，还是没有打印出sql日志，感觉好像是nutz的日志没有交给log4j2去管理似的

@qq_16dd5808 仔细看pom.xml

来自炫酷的 NutzCN

pom.xml也没发现什么问题。下面是我的

<!-- log4j2日志依赖 -->

加 log4j-1.2-api

成功。加了

<dependency>
            <groupId>org.apache.logging.log4j</groupId>
            <artifactId>log4j-1.2-api</artifactId>
            <version>2.6.2</version>
        </dependency>

就可以了。多谢@wendal
