Question

我想通过 applicationContext.xml 而不是 web.xml 配置 log4j2.xml 文件。如果此 log4j2.xml 文件存在于 classpath 中，我无法对此文件进行任何更改。所以，我应该配置这个 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>

我认为 LoggerContext class 没有 setConfigLocation() 方法，因为 getContext() return log4j-api 的 LoggerContext class 不是 log4j-core 的。

我该如何处理这种情况？感谢您的帮助。

我使用了如下所示的代码，当我使用 Tomcat 服务器时我成功了，但是如果我使用 WebSphere 服务器，程序不会将日志打印到文件中。

<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>
