tomcat啟動時卡在：

一般這樣的問題是兩個原因：

1. 資料庫連線不上；

2. mapper.xml 中有錯誤，比如單詞拼寫錯誤；

這個問題不是，採取的方法是 把專案的日誌級別調整為debug模式，檢視詳細列印資訊：

spring-mybatis.xml

<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">     <property name="basePackage"               value="xxx.xxx.xxx.x.core.*.dao"/> </bean>  兩個spring-mybatis.xml 的MapperScannerConfiguer中 都沒有指定sqlSessionFactory。 ---------------------  作者：sumi  來源：CSDN  原文：https://blog.csdn.net/wconvey/article/details/55006768  版權宣告：本文為博主原創文章，轉載請附上博文連結！
