如何将Spring log4j与messages.properties集成？

<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
    <property name="locations">
        <list>
            <value>classpath:messages.properties</value>
        </list>
    </property>
</bean>

<bean id="log4jConfigurer" class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">
    <property name="targetClass" value="org.springframework.util.Log4jConfigurer" />
    <property name="targetMethod" value="initLogging" />
    <property name="arguments">
        <list>
            <value>classpath:log4j.properties</value>
        </list>
    </property>
</bean>

log.error=An error occurred: {0}
log.info=Information: {0}

@Autowired
private MessageSource messageSource;

public void logError(String errorMessage) {
    String errorLogMessage = messageSource.getMessage("log.error", new Object[]{errorMessage}, Locale.getDefault());
    // 使用log4j记录日志
    Logger.getLogger(getClass()).error(errorLogMessage);
}
