Spring Manual ROLLBACK TRANSACTION

In spring's configuration file, if the data source's Defaultautocommit is set to True, the transaction is not rolled back if the exception is caught by itself in the method, and the transaction rolls back if the exception is not caught by itself, as in the following example:

<bean id= "DataSource" class= "xxx" >  
   <property name= "xxx" value= "xxx"/> <property "xxx"  
   value= "xxx"/> ...  
                     .  
     <property name= "Defaultautocommit" value= "true"/>  

Examples are as follows:

@Transactional (rollbackfor = {Exception.class}) public  
void Test () {  
    try {   

     } catch (Exception e) {  
          E.pri Ntstacktrace ();     
          Transactionaspectsupport.currenttransactionstatus (). Setrollbackonly (); This is the sentence
     }
