关于Spring整合mybatis时配置MapperScannerConfigurer的问题

这是之前我用Spring整合mybatis的时候出过的错：Mark下。

在配置MapperScannerConfigurer的时候我配置SQLSessionFactoryBeanName，不管是maven install还是启动tomcat都会出这个错

解决方法： 应为我之前配置的mybatis.cfg.cml文件中配置的mapper.xml是只配置了一个。就没有配置package，将配置的mapper.xml文件删掉。配置package就能解决

严重: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener
