Therefore, if an uncaptured exception is thrown in the program, the transaction will be rolled back. See the following code: [java] public RPCMessage saveUser (TUmUserDTO entity) <span style = "color: # ff0000;"> throws DaoException </span> {log.info ("service layer operation: add a practitioner saveUser (TUmUserDTO ["+ entity +"]) "); Try {if (entity = null) {throw new ServiceException (ServiceException. ERRORCODE_PARAM_NULL);} If rollback-for = "ServiceException" is caught in the program, the transaction will not be rolled back because the exception is swallowed up and the transaction has been committed, see the following code: [java] log. debug ("service layer operation: practitioner role edited"); return this. getRPCMessage ();} catch (<span style = "color: # ff0000;"> ServiceException </span> e) {return this. getRPCMessage (e);} If rollback-for = "Exception", it belongs to the Exception and Exception packets. All exceptions are rolled back by transactions. Here, because DaoException and ServiceException are inherited from Exception, they are also rolled back. Expression = "execution (* com. xbzc. phr. service. um. userManageSrv. *(..)) "/> is used to determine which classes of methods are used when a transaction is rolled back. If rollback-for = "" is not configured, only operations that are caused by exceptions that are not captured are rolled back by default.
