java - How to make sure multiple DBs are transacted with a single transaction manager in spring? -


i using mulitple transaction managers (hibernatetransactionmanager) 1 each database.

during 1 code flow believe start/finish multiple transactions each database.

i want make sure database transactions part of single transaction. how can acheive this?

one of post here suggest use jtatransaction manager, should use in combination using hibernate?

although think in case of execption during phase of application, transactions rolled back.

i using spring 4.1.* , hibernate 3.6.* , not using webcontainer.

it years since worked hibernate, apologies in advance if of misleading.

  • you need jta transactions. datasources need support jta.
  • if running in web container weblogic or websphere, creating jta transaction easy. don't think tomcat suffice here. command line program, have not found answer.
  • if have full control on 3 databases, should fine. aware rollback on systems involve web services can patchy or require non-standard protocols (e.g. weblogic supports soap jta on t3 protocol)

if results, please share amount of advice in area minimal.

(edit)just noticed stated not using web container. if come across solution command line program, there lots of know. building junit tests distributed transactions want do, have never found how generate jta transaction object (/edit>)

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
