spring + mybatis 下出现JDBC Connection *** will not be managed by Spring错误

框架   druid 、spring 4.1.3 、mybatis 3.2.8

访问时日志打印

同事事务也不生效

事务配置

数据库连接配置

调试很久没排查到错误，最后想到是不是配置切点扫描表达式的问题，仔细看了切点表达式

execution(* com.ciguo.service.*.*(..))

这种写法是扫描到service下一级*.java里面的方法，显然是找不到的，于是乎改成

execution(* com.ciguo.service.*.impl.*.*(..))

impl后面第一个 *  表示Java类，第二个 * 表示方法 这样子就能扫描到了，重启测试，

SqlSession现在已经被spring管理了，事务也生效了
