方法开始
方法刚进入test方法，还未执行具体逻辑

上面这段日志实际上是由动态代理类打印出来
1.创建事务
2.获取数据库连接a
3.将a设置为手动提交
第一步
执行 investMapper.selectById("1");

从上面可以看出,
1.虽然assetNew上没是事务,但是
org.mybatis.spring.transaction.SpringManagedTransaction - JDBC Connection [com.dangdang.ddframe.rdb.sharding.jdbc.core.connection.ShardingConnection] will be managed by Spring
2.committing SqlSession不是提交事务！！！
Committing JDBC transaction才是。
