Set Time Zone conversion for iOS
Sometimes, in order to unify the time in the system, the time zone that needs to be exchanged between the server and the client, for example, using GMT.The code for converting an iPhone is as follows:
Nsdate * Now = [nsdate date];Nslog (@ "% @", [now description]);Nstimezone * defaulttimezone = [nstimezone defaulttimezone];Nstimezone * tzgmt = [nstimezone timezonewithname: @ "GMT"];[Nstimezone setdefatimetimezone
2, 2, 0, 0On the sender side, set the command at + CSMP = 17,167, 0,240 (when sending in PDU format, 240 is changed to the string DCS (F0 ))C) when the program finds the format of the Short Message prefix + CMT followed by the transmitted data, it immediately captures the short message and delivers it to the original address.D) If CSMP = 17,167, 0,240 is not set on the sending end, the captured short message should have a prefix + cmti. At this time,

Any help is really appreciated. Thanks in advance

I finally understood the problem and able to resolve it.
As @ zerologiko commented the issue is with transaction. I am using spring managed transaction with hibernate. Once I declare my transaction policy, spring takes care of start/end of transactions.
Reason for the issue in my case: Spring bean life cycle is not valid tive in

Previous Code: @ transactionattribute (transactionattributetype. Required) // sets the propagation feature of a transaction to required.
In the previous article, why is the propagation feature set to required?
There are 7 transaction propagation features:
1. propagation_required: if a transaction exists, the current transaction is supported. Enable if no transaction exists2
transaction result;
Propagation_not_supported: fooled the current context transaction, in non-transaction mode;
Propagation_never: execution is not allowed in the transaction context. If a transaction exists in the current context, an exception is thrown;
Propagation_nested: Embedded transactions (no equivalent concept in EJB), only supported in some transactionmanagers. Only supported in JDBC 3.0 + datasourcetransactionmanager;
If a transaction exists, it is executed in the nested tran
, Hibernate Transaction is obtained from the Session, tx = session. beginTransaction (), submit tx first, and then session. close, which fully complies with the Operation Sequence of the JDBC Transaction, but this sequence is totally different from the Transactioin Operation Sequence of JTA !!! JTA starts Transaction first, then starts the Session, closes the Session, and finally submits the Transaction. Therefore, when you use the Transaction of JTA, never use the Transaction of Hibernate, it s
