解决了吗？？？？我也是这样的问题。AreaService的bean总是失败，AreaDao没问题
java.lang.IllegalStateException: Failed to load ApplicationContext
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'shopServiceImpl' defined in file [/Users/apple/IdeaProjects/myo2o/target/classes/com/harry/o2o/service/impl/ShopServiceImpl.class]: Initialization of bean failed; nested exception is java.lang.NoClassDefFoundError: org/apache/commons/fileupload/FileUploadException

同学好，首先可以尝试右键tomcat server 然后 clean 看看；如果不行，在还没有解决类似问题的能力之前，还是和视频里一样的配置，spring-service.xml里
<context:component-scan base-package="com.imooc.o2o.service" />
到service而不是到impl
其次，
serviceimpl里直接
@Service public class AreaServiceImpl implements AreaService {即可
