　　今天再项目里添加新功能时，突然爆出 

　　org.springframework.beans.factory.BeanCreationException: Error creating bean with name \'accountSeqService\': Injection of autowired dependencies failed; nested exception is 　　　　org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.tjgjk.mapper.account.card.AccountSeqMapper 　　com.tjgjk.service.account.card.impl.AccountSeqServiceImpl.accountSeqMapper; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 　　[com.tjgjk.mapper.account.card.AccountSeqMapper] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

　　当时就一顿好找，因为错误中提示是在 解析XML文件时出错，所以在XML里来来回回查找三、四遍，愣是没找到具体错误原因，

　　  然后是在受不了了就去Google了下，没想到具体原因实在是让人难以启齿啊，见图

　　

　　JavaType对应的是类里的数据类型，jdbcType对应数据库里的类型

　　jdbcType被我写成了javaType，想哭，也在此提醒下各位小伙伴，使用快捷键时一定要看好是不是所对应的方法，

　　  以此，给自己一个警告。
