• spring mvc mybatis 整合錯誤1

（放置事務註解的位置錯誤）（表現：直接訪問.jsp,.html報錯，寫一個測試類，測試mapper，報錯）
org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Cannot locate BeanDefinitionDecorator for element [annotation-driven]

• 整合錯誤2（dataSource拼寫錯誤）

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

• 整合錯誤3(springmvc.xml 註解驅動配置錯誤 修改後未解決，仍然報一下錯誤。註解@Service 和@Controller，仍然報錯。最後直接專案刪了，重新copy配置檔案，問題解決了。等於說是又建了一個，autowired dependencies failed還是沒有解決)    

Error creating bean with name 'itemsController': Injection of autowired dependencies failed; 
//錯誤的建立名為‘xxx’（原因）：自動接入依賴的注入失敗
