若要为返回void的接口指定为单向消息交换模式,请将IsOneWay属性设置为true,默认是请求与响应模式为false.

若要为返回Void的操作指定单向消息交换,请将IsOneWay属性设置为true,默认为false. 此方法与前面的请求/答复示例相同,单思,将IsOneWay属性设置为true意味着尽管方法相同,服务操作也不会发送返回消息,而客户端将在出站消息抵达通道层时立即返回 双工模式 --双工模式的特点是 [OperationContract(IsOneWay=true)] void TestMethod(string strInput); 在接口定义方法加上IsOneWay=true ,即表示客户端调用的该方法为单向模式,IsOneWay在默认的情况下值为false的。 typeof(IClientCallBack)))] public interface ICalculatorService { [OperationContract(IsOneWay

ref或者out类型的参数,至于为什么,请参考C# ref与out关键字解析 (3)、使用单项模式的服务端接口没有返回值,返回类型只能为void (4)、通过设置OperationContract契约的IsOneWay namespace IService { [ServiceContract] public interface IOneWay { [OperationContract(IsOneWay

在定义Service Contract的时候,如果我们没有为某个Operation显式指定为One-way (IsOneWay = true), 那么默认采用Request/Response方式。 typeof(ICalculatorCallback))] public interface IDuplexCalculator { [OperationContract(IsOneWay { //[ServiceContract] public interface ICalculatorCallback { [OperationContract(IsOneWay

可以看到这两行代码: boolean isAsync = RpcUtils.isAsync(getUrl(), invocation); boolean isOneway = RpcUtils.isOneway 首先我们可以看到isOneway的判断还是我们熟悉的代码。但是这里只有一个if-else了。Dubbo调用有四种方式,if判断了isOneway,那么剩下的三种都在这个else里面啦。
Dubbo里面通过参数isOneway、isAsync来控制调用方式: isOneway=true 表示异步不带回调 isAsync=true 表示异步带回调 上述两种情况都不满足,使用同步API 同步调用
