【错误】 Error creating bean with name 'articleManageMapper' defined in file

问题： Wrong namespace. Expected 'com.practice.mapper.ArticleManageMapper' but found 'com.practice.mapper'

分析：错误的命名空间应该是com.practice.mapper.ArticleManageMapper但是实际设置称为了com.practice.mapper

解决：将com.practice.mapper.ArticleManageMapper.xml中的namespace值改为com.practice.mapper.ArticleManageMapper就可以了。
