- spring mvc mybatis 整合错误1
（放置事务注解的位置错误）（表现：直接访问.jsp,.html报错，写一个测试类，测试mapper，报错）
org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Cannot locate BeanDefinitionDecorator for element [annotation-driven]
- 整合错误2（dataSource拼写错误）
Offending resource: class path resource [applicationContext.xml]
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'transactionManager' defined in class path resource [applicationContext.xml]: Cannot resolve reference to bean 'dataSouorce' while setting bean property 'dataSource'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'dataSouorce' is defined
- 整合错误3(springmvc.xml 注解驱动配置错误 修改后未解决，仍然报一下错误。注解@Service 和@Controller，仍然报错。最后直接项目删了，重新copy配置文件，问题解决了。等于说是又建了一个，autowired dependencies failed还是没有解决)
Error creating bean with name 'itemsController': Injection of autowired dependencies failed;
