mybatis报错：Error creating bean with name 'xxxDao' defined

Question

mybatis报错：

Error creating bean with name 'xxxDao' defined in file [xxx]: cannot resolve reference to bean 'sqlSessionFactory' while setting bean property 'sqlSessionFactory'...
Error creating bean with name 'yyyDao' defined in file [xxx]: cannot resolve reference to bean 'sqlSessionFactory' while setting bean property 'sqlSessionFactory'...
Error creating bean with name 'zzzDao' defined in file [xxx]: cannot resolve reference to bean 'sqlSessionFactory' while setting bean property 'sqlSessionFactory'...

是一个老项目的新需求，我写完一个接口的一套mvc，把mymapper.xml添加到mybatis的config.xml以后就出现这个错误，主要是报错的'xxxDao' 'yyyDao' 都不是我写的，我也没动过。。。请问是哪里配置错了

Answer 1

日志应该多贴一些过来
我猜可能是数据库配置出了点问题,不小心改到了或者网络问题,DB那边修改了等等可能

Answer 2

mybatis 配置文件是不是被你修改了，导致扫描不到类

Answer 3

感觉是数据库配置有问题导致数据库连不上，报错里有SessionFactory创建失败的日志
