本文记录了一次开发过程中遇到的问题：MyBatis中由于Mapper文件内的方法重复导致的SQLSessionFactory创建失败。通过分析错误日志，最终定位到具体问题并解决了方法名重复的问题。

[DEBUG]-[org.mybatis.spring.SqlSessionFactoryBean.buildSqlSessionFactory(SqlSessionFactoryBean.java:431)] 一直在创建sqlsession工厂原因

今天在做开发项目的时候出现一直在控台输出创建sqlsessionfactory'这个代码,

tomcat一直在控制台上输出这个内容无法停止下来,那么到底是什么原因呢,

我们可以在输出信息上看到有个warn信息,也可以看error信息
