關於slf4j和log4j沖突問題（自己項目配置文件不生效）

用-Dlog4j.debug可以打印出配置log4j的配置文件加載的信息

mvn dependency:tree 看依賴信息

然后排除掉重復得依賴

<dependencies>
<dependency>
<groupId>org.apache.storm</groupId>
<artifactId>storm-core</artifactId>
<version>1.1.0</version>
<scope>provided</scope>
<exclusions>
<exclusion>
<artifactId>logback-classic</artifactId>
<groupId>ch.qos.logback</groupId>
</exclusion>
<exclusion>
<artifactId>logback-core</artifactId>
<groupId>ch.qos.logback</groupId>

<exclusion>
<groupId>org.slf4j</groupId>
<artifactId>log4j-over-slf4j</artifactId>
</exclusion>

<exclusion>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-slf4j-impl</artifactId>
</exclusion>
</exclusions>
<!--本地調試的時候，屏蔽掉scope，等打包時候再放開 -->
<!--<scope>provided</scope> -->

</dependency>

正確排除得話會看到自己得日志配置文件生效
