Transaction rolled back because it has been marked as rollback-only

今天遇到的异常

1. Invalid connection string format, a valid format is: "//host[:port][/service_name]"

这个异常是在配置oracle数据源的时候配置的格式不对

2. Transaction rolled back because it has been marked as rollback-only
   这个是因为spring的事务嵌套导致的

解决方式可以看这个两篇文章
