mybatis+spring配置的时候出错了

Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sqlSessionFactory' defined in ServletContext resource [/WEB-INF/classes/spring-config.xml]: Invocation of init method failed; nested exception is org.springframework.core.NestedIOException: Failed to parse config resource: class path resource [mybatis-config.xml]; nested exception is org.apache.ibatis.builder.BuilderException: Error parsing SQL Mapper Configuration. Cause: org.apache.ibatis.builder.BuilderException: Error parsing Mapper XML. Cause: org.apache.ibatis.builder.BuilderException: Error resolving class. Cause: org.apache.ibatis.type.TypeException: Could not resolve type alias 'User'. Cause: java.lang.ClassNotFoundException: Cannot find class: User
求大神指导啊 什么错误啊

Answer 1

Mapper 配置文件发出来

追问

为什么啊

追答

因为你的配置文件错了

Answer 2

这是说无法创建sqlsessionfactory
原因是你的mybatis-config.xml 找不到 User这个类

你看看mybatis里有没有生名这个User类

追问

找到错误拉，是因为数据结构设计外键设计错了，但是由于mysql连接的jar的版本问题，所以没有提示到正确的错误
