problem
创建了spring工程，设置了bean，
测试时报错：
// bean方式创建实例
ApplicationContext context = new ClassPathXmlApplicationContext("beans.xml");
Hello hello = (Hello) context.getBean("hello");
System.out.println(hello.toString());
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory
附带问题：
maven reimport报错：unable to import maven project see logs for detail
详情：

solution
尝试过的处理:
- 删除maven repo下的org
- 重新 maven install
- idea清除缓存重启：idea-file-invalidate caches/restart-Invalidate and Restart
重新导入项目：
- 删除maven项目: idea-maven-右键root-remove projects
- 重新导入: 重启idea-open-pom.xml文件, 选择 delete Existing Project and Import
- 再次运行: 正常，maven reimport 正常
