tomcat啓動時卡在：
一般這樣的問題是兩個原因：
1. 數據庫連接不上；
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 把項目的日誌級別調整爲debug模式，查看詳細打印信息：

statistic-spring-mybatis.xml
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage"

</bean>
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。
