Spring @Transactional annotation when using try catch block

Question

If we catch the exception in method annotated with the @Transactional annotation, will it roll back if any exception occurs?

@Transactional(readOnly = false, propagation = Propagation.REQUIRED, rollbackFor=Throwable.class) public void yearEndProcess() {     try {         // try block     } catch (Throwable throwable) {         // catch block     } } 

Answer 1

for example

class A{          @Transactional     public Result doStuff(){         Result res = null;         try {           // do stuff          } catch (Exception e) {                      }         return res ;     } } 

If there is an exception in the method doStuff the transaction isn't rolled back.

To rollback the exception programmatically, we can do something like below.

declarative approach

@Transactional(rollbackFor={MyException1.class, MyException2.class, ....}) public Result doStuff(){    ... } 

programmatic rollback

you need to call it from TransactionAspectSupport.

    public Result doStuff(){       try {         // business logic...       } catch (Exception ex) {         // trigger rollback programmatically         TransactionAspectSupport.currentTransactionStatus().setRollbackOnly();       }     } 

You are strongly encouraged to use the declarative approach to rollback if at all possible. Programmatic rollback is available should only be used if you absolutely need it.
