Java - How to configure log4j2.xml

I want to configure log4j2.xml file via my applicationContext.xml not web.xml. If this log4j2.xml file exist in classpath, I can't make any change in this file. So, I should configure with this applicationContext.xml.

pom.xml

<dependency> 
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-simple</artifactId>
    <version>1.6.0</version>
    </dependency>
<dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-api</artifactId>
    <version>2.11.1</version>
</dependency>
<dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-core</artifactId>
    <version>2.11.1</version>
</dependency>
<dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-1.2-api</artifactId>
    <version>2.11.1</version>
</dependency>
<dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-web</artifactId>
    <version>2.11.1</version>
</dependency>
<dependency>
    <groupId>commons-logging</groupId>
    <artifactId>commons-logging</artifactId>
    <version>1.2</version>
</dependency>

applicationContext.xml

<bean id="log4jInitialization" class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">
        <property name="targetClass"
                  value="org.apache.logging.log4j.LogManager" />
        <property name="targetMethod" value="getContext" />
        <property name="arguments">
            <list>
                <value>false</value>
            </list>
        </property>
    </bean>

    <bean id="log4jContext" class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">
        <property name="targetObject" ref="log4jInitialization"/>
        <property name="targetMethod" value="setConfigLocation"/>
        <property name="arguments">
            <list>
                <value>C:/projects/conf/log4j2.xml</value>
            </list>
        </property>
    </bean>

I think LoggerContext class does not have a setConfigLocation() method because getContext() return log4j-api's LoggerContext class not log4j-core's.

How can I handle this situation? Thank you for your help.

I used code as shown below, and I succedded when I using Tomcat Server but If I use WebSphere Server, Program does not print logs into file.

<bean id="log4jInitialization" class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">
    <property name="targetClass"
              value="org.apache.logging.log4j.core.LoggerContext" />
    <property name="targetMethod" value="getContext" />
    <property name="arguments">
        <list>
            <value>false</value>
        </list>
    </property>
</bean>

<bean id="log4jContext" class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">
    <property name="targetObject" ref="log4jInitialization"/>
    <property name="targetMethod" value="setConfigLocation"/>
    <property name="arguments">
        <list>
            <!--<value>classpath:log4j2.xml</value>-->
            <value>file:c:/projects/conf/log4j2.xml</value>
        </list>
    </property>
</bean>
