c.如果是已用了commons-logging/log4j想用用slf4j/logback，那也容易用下面的配置
<!-- slf4j -->
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
</dependency>
<!-- common-logging 實際調用slf4j -->
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>jcl-over-slf4j</artifactId>
</dependency>
<!-- log4j -->
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>log4j-over-slf4j</artifactId>
</dependency>
<dependency>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-core</artifactId>
</dependency>
<dependency>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-classic</artifactId>
</dependency>
再到http://logback.qos.ch/translator/Welcome.do，將你原來的log4j.properties轉成logback.xml
就可以將commons-logging.jar 跟 log4j.jar自你系統中移除了
