log4j 打印sql

有兩個工程一樣的環境（mybatis+spring mvc+spring+maven）一樣的log4j配置，有一個能正常打印sql，有一個死活不打印，info信息等都能輸出就是不輸出sql，添加slf4j包以後又能正常打印，想不通到底爲啥呢。有大神但願指點下。

slf4j包：

    <dependency>

        <groupId>org.slf4j</groupId>

<artifactId>slf4j-log4j12</artifactId>

<version>1.7.5</version>

</dependency>

        <dependency>

<groupId>org.slf4j</groupId>

<artifactId>slf4j-api</artifactId>

<version>1.7.5</version>

</dependency>

log4j配置文件：
