我不通过controller层调用service接口，而是使用main方法通过ClassPathXmlApplicationContext调用service接口，
会报No unique bean of type [com.ultrapower.demo.service.impl.AppServiceImpl] is defined: expected single bean but found 0:
main方法代码如下：
public static void main(String[] args) {
        String path="D:\\software\\apache-tomcat-6.0.45\\webapps\\QuartzTest\\WEB-INF\\conf\\beans\\*.xml";
        ApplicationContext applicationContext = new ClassPathXmlApplicationContext("file:"+path);
        IAppService iAppService = applicationContext.getBean(AppServiceImpl.class);
        String appStr = iAppService.getApp();
        System.out.println(appStr);
    }
dao的配置
<bean id="iAppDao" class="com.ultrapower.demo.dao.impl.AppDaoImpl" parent="baseDao">
    </bean>
service的配置：
<bean id="iAppService" class="com.ultrapower.demo.service.impl.AppServiceImpl"
        parent="baseService" >
        <property name="iAppDao" ref="iAppDao" />
    </bean>
报错：log4j:WARN No appenders could be found for logger (org.springframework.context.support.ClassPathXmlApplicationContext).
