call chain :

serverA -> serverB

serverA method describtion:

Execute the local transaction first.(insert data into db.)
and use feign to call remote serverB.
next , throw RunTimeException();

serverB method describtion:
Only Execute the local transaction.
insert data into db.

now.......

serverB is Insert the success .
serverA is insert failure...because serverA throw RunTimeException;

---

so ............

serverB Should be rolled back ！！！！

but serverB insert success ??????? WHY ????

serverA 。

call serverB ，first..
next , throw RunTimeException()

Notice the order of execution ..........

BTM does not implement anything that would make transactions propagate across servers. I don't think there's ever been a protocol to do that over REST (like WS-AT does for SOAP).

In short: this isn't supported and cannot work.
