spring使用中一个问题

[better_chaner]

Resource res = new ClassPathResource("bean.xml");
BeanFactory factory = new XmlBeanFactory(res);
Messages mess = (Messages)factory.getBean("OP1");
System.out.println("Message:" + mess.getValue());

Messages为实体类


在使用上面的方法时，一直会出现

这个日志怎么去除掉呢？？？

[magong]

找到log4j.properties文件，将行
log4j.rootLogger = debug
中的这个debug改成info好了

缺少包org.apache.commons.collections.map.CaseInsensitiveMap
追加commons-collection包
