public class JmsTransactionManager
extends AbstractPlatformTransactionManager
implements ResourceTransactionManager, InitializingBean
```
PlatformTransactionManager implementation for a single JMS ConnectionFactory. Binds a JMS Connection/Session pair from the specified ConnectionFactory to the thread, potentially allowing for one thread-bound Session per ConnectionFactory.
This local strategy is an alternative to executing JMS operations within JTA transactions. Its advantage is that it is able to work in any environment, for example a standalone application or a test suite, with any message broker as target. However, this strategy is not able to provide XA transactions, for example in order to share transactions between messaging and database access. A full JTA/XA setup is required for XA transactions, typically using Spring's JtaTransactionManager as strategy.
Application code is required to retrieve the transactional JMS Session via ConnectionFactoryUtils.getTransactionalSession(javax.jms.ConnectionFactory, javax.jms.Connection, boolean) instead of a standard Java EE-style ConnectionFactory.createConnection() call with subsequent Session creation. Spring's JmsTemplate will autodetect a thread-bound Session and automatically participate in it.
Alternatively, you can allow application code to work with the standard Java EE-style lookup pattern on a ConnectionFactory, for example for legacy code that is not aware of Spring at all. In that case, define a TransactionAwareConnectionFactoryProxy for your target ConnectionFactory, which will automatically participate in Spring-managed transactions.
The use of CachingConnectionFactory as a target for this transaction manager is strongly recommended. CachingConnectionFactory uses a single JMS Connection for all JMS access in order to avoid the overhead of repeated Connection creation, as well as maintaining a cache of Sessions. Each transaction will then share the same JMS Connection, while still using its own individual JMS Session.
The use of a raw target ConnectionFactory would not only be inefficient because of the lack of resource reuse. It might also lead to strange effects when your JMS driver doesn't accept MessageProducer.close() calls and/or MessageConsumer.close() calls before Session.commit(), with the latter supposed to commit all the messages that have been sent through the producer handle and received through the consumer handle. As a safe general solution, always pass in a CachingConnectionFactory into this transaction manager's "connectionFactory" property.
Transaction synchronization is turned off by default, as this manager might be used alongside a datastore-based Spring transaction manager such as the JDBC DataSourceTransactionManager, which has stronger needs for synchronization.

```
public JmsTransactionManager()
```
    Create a new JmsTransactionManager for bean-style usage.
    Note: The ConnectionFactory has to be set before using the instance. This constructor can be used to prepare a JmsTemplate via a BeanFactory, typically setting the ConnectionFactory via setConnectionFactory.
    Turns off transaction synchronization by default, as this manager might be used alongside a datastore-based Spring transaction manager like DataSourceTransactionManager, which has stronger needs for synchronization. Only one manager is allowed to drive synchronization at any point of time.

    This target resource factory is usually used as resource key for TransactionSynchronizationManager's resource bindings per thread.

  - doGetTransaction
```
protected Object doGetTransaction()
```
    从类复制的说明: AbstractPlatformTransactionManager
    Return a transaction object for the current transaction state.
    The returned object will usually be specific to the concrete transaction manager implementation, carrying corresponding transaction state in a modifiable fashion. This object will be passed into the other template methods (e.g. doBegin and doCommit), either directly or as part of a DefaultTransactionStatus instance.
    The returned object should contain information about any existing transaction, that is, a transaction that has already started before the current getTransaction call on the transaction manager. Consequently, a doGetTransaction implementation will usually look for an existing transaction and store corresponding state in the returned transaction object.
    指定者:
    doGetTransaction 在类中 AbstractPlatformTransactionManager
    返回:
    the current transaction object

  - isExistingTransaction
```
protected boolean isExistingTransaction(Object transaction)
```
    从类复制的说明: AbstractPlatformTransactionManager
    Check if the given transaction object indicates an existing transaction (that is, a transaction which has already started).
    The result will be evaluated according to the specified propagation behavior for the new transaction. An existing transaction might get suspended (in case of PROPAGATION_REQUIRES_NEW), or the new transaction might participate in the existing one (in case of PROPAGATION_REQUIRED).
    The default implementation returns false, assuming that participating in existing transactions is generally not supported. Subclasses are of course encouraged to provide such support.
    覆盖:
    isExistingTransaction 在类中 AbstractPlatformTransactionManager
    参数:
    transaction - the transaction object returned by doGetTransaction

```
protected void doBegin(Object transaction,
                       TransactionDefinition definition)
```
    从类复制的说明: AbstractPlatformTransactionManager
    Begin a new transaction with semantics according to the given transaction definition. Does not have to care about applying the propagation behavior, as this has already been handled by this abstract manager.
    This method gets called when the transaction manager has decided to actually start a new transaction. Either there wasn't any transaction before, or the previous transaction has been suspended.
    A special scenario is a nested transaction without savepoint: If useSavepointForNestedTransaction() returns "false", this method will be called to start a nested transaction when necessary. In such a context, there will be an active transaction: The implementation of this method has to detect this and start an appropriate nested transaction.
    指定者:
    doBegin 在类中 AbstractPlatformTransactionManager
    参数:
    transaction - the transaction object returned by doGetTransaction
    definition - a TransactionDefinition instance, describing propagation behavior, isolation level, read-only flag, timeout, and transaction name
  - doSuspend
```
protected Object doSuspend(Object transaction)
```
    从类复制的说明: AbstractPlatformTransactionManager
    Suspend the resources of the current transaction. Transaction synchronization will already have been suspended.
    The default implementation throws a TransactionSuspensionNotSupportedException, assuming that transaction suspension is generally not supported.
    覆盖:
    doSuspend 在类中 AbstractPlatformTransactionManager
    参数:
    transaction - the transaction object returned by doGetTransaction
    返回:
    an object that holds suspended resources (will be kept unexamined for passing it into doResume)

    Resume the resources of the current transaction. Transaction synchronization will be resumed afterwards.
    The default implementation throws a TransactionSuspensionNotSupportedException, assuming that transaction suspension is generally not supported.

```
protected void doCommit(DefaultTransactionStatus status)
```
    从类复制的说明: AbstractPlatformTransactionManager
    Perform an actual commit of the given transaction.
    An implementation does not need to check the "new transaction" flag or the rollback-only flag; this will already have been handled before. Usually, a straight commit will be performed on the transaction object contained in the passed-in status.
    指定者:
    doCommit 在类中 AbstractPlatformTransactionManager

    从类复制的说明: AbstractPlatformTransactionManager
    Set the given transaction rollback-only. Only called on rollback if the current transaction participates in an existing one.
