基于WCF框架的分布式事务处理方案

第一：服务契约(ServiceContract)中的配置

　

　ServiceContract(SessionMode = SessionMode.Required)]

    public interface IDistributedTransaction

    {

        [TransactionFlow(TransactionFlowOption.Allowed)]

        [OperationContract]

        void Add();

    }

契约 Code

 

第二：服务契约实现的配置

　　

[OperationBehavior(TransactionAutoComplete = true, TransactionScopeRequired = true)]

        public void Add()

        {

            conn1.Open();

            SqlCommand command = new SqlCommand("insert into test2 values(111)", conn1);

            command.ExecuteNonQuery();

            DataBaseOperation.DisplayTransactioninfo.Display(System.Transactions.Transaction.Current);

        }

契约实现 Code

 

第三：WebConfig 配置

<service name="ServerConsole.Transaction.DistributedTransactionService1" behaviorConfiguration="metadatabehaviors">



        <host>

          <baseAddresses>

            <add baseAddress="http://localhost:8027"/>

            <add baseAddress="net.tcp://localhost:8028"/>

          </baseAddresses>

        </host>

        <endpoint address="DistributedTransactionService1" binding="netTcpBinding" bindingConfiguration="tranbinding"

                   contract="ServerConsole.Transaction.IDistributedTransaction"></endpoint>

      </service>

<bindings>

      <netTcpBinding>

          <binding name="tranbinding" transactionFlow="true" transactionProtocol="WSAtomicTransactionOctober2004">

          <reliableSession enabled="true" ordered="true"/>

        </binding>

      </netTcpBinding>

    </bindings>

WebConfig Code

 

第四：客户端 使用

 using (TransactionScope transcope = new TransactionScope())

            {

                try

                {

                    Transaction.Current.TransactionCompleted += new TransactionCompletedEventHandler(Current_TransactionCompleted);

                    tranclient.Add();

                    tranclient2.Add();

                    transcope.Complete();

                }

                catch (Exception err) { Transaction.Current.Rollback(); }

            }

 

static void Current_TransactionCompleted(object sender, TransactionEventArgs e)

        {

            if (e.Transaction.TransactionInformation.Status ==

                System.Transactions.TransactionStatus.Committed)

                Console.WriteLine(e.Transaction.TransactionInformation.DistributedIdentifier);

        }

客户端使用TransactionScope类来进行环境事务的设置，这样就很方便知道事务的执行范围，在TransactionScope里面我们可以通过Transaction.Current获取到当前上下文的事务对象，由于事务对象是存储在线程独立存储区里的，所以跨线程访问是没用的，通过依赖事务进行传递。
