Maven：程序包org.apache.log4j不存在问题处理

 <dependency>
        <groupId>log4j</groupId>
        <artifactId>log4j</artifactId>
        <version>1.2.15</version>
        <exclusions>
          <exclusion>
            <groupId>javax.mail</groupId>
            <artifactId>mail</artifactId>
          </exclusion>
          <exclusion>
            <groupId>javax.jms</groupId>
            <artifactId>jms</artifactId>
          </exclusion>
          <exclusion>
            <groupId>com.sun.jdmk</groupId>
            <artifactId>jmxtools</artifactId>
          </exclusion>
          <exclusion>
            <groupId>com.sun.jmx</groupId>

          </exclusion>
        </exclusions>
        <scope>compile</scope>
      </dependency> 

 注意log4j的scope为<scope>compile</scope>
