WCF 4.0 SOA承诺作为Transcation

Question

在WCF 4.0中,如何将3个不同的服务操作作为单个事务提交？(在SOA中提交)

我有3个不同的WCF服务,如下所示,每个服务方法调用DB操作

service1.CreateEmployee();

service2.SendSetupRequestForEmployee();

service3.GiveOfficePermissionToEmployee();

即使一个操作失败,整个事情也应该回滚......任何帮助都会受到赞赏.

简短的回答:在a下进行服务呼叫TransactionScope,并确保将呼叫本身设置为在事务下运行.

TLDR 在这里阅读这篇文章.

基本上,您需要装饰您的Operation Contract方法:

[TransactionFlow(TransactionFlowOption.Allowed)]
void MyWcfServiceCall() {...}

并且服务方法调用自身:

[OperationBehavior(TransactionScopeRequired = true)]
void MyWcfServiceCall() {...}

并打电话给 TransactionScope

using (TransactionScope tx = new TransactionScope(TransactionScopeOption.RequiresNew)) {
    myServiceClient.MyWcfServiceCall();
    myOtherServiceClient.MyOtherWcfServiceCall();
    tx.Complete();
}

在配置文件中绑定,将transactionFlow设置为true:

<bindings>
    <wsHttpBinding>
        <binding name="MyServiceBinding" transactionFlow="true" ... />
    </wsHttpBinding>
</bindings>
