Question

我创建了Ignite服务，它实现了Service和虚拟测试接口。我试图通过下面的代码

调用Test接口方法

IgniteServiceTestInterface cntrSvc = ignite.services()
    .serviceProxy("IgniteServiceTestInterface", IgniteServiceTestInterface.class, false);
System.out.println(cntrSvc.invokeNext(1));

方法已在Service中实现，并在调用时返回下一个计数器。但相反，我收到如下错误

Exception in thread "main" class org.apache.ignite.IgniteException: Failed to find deployed service: IgniteServiceTestInterface
at org.apache.ignite.internal.processors.service.GridServiceProxy$ProxyInvocationHandler.invoke(GridServiceProxy.java:167)

有谁可以告诉我，我错过了哪些文字

Answer 1

它工作正常，服务名称与注册服务不匹配。一旦我纠正了它，我就可以调用服务名称。

Answer 2

这可能有助于想要快速部署点火服务的人：

Config config = ConfigFactory.load();
String configFile = "ignite.xml";
Ignite ignite = Ignition.start(configFile);

// Deployment the service
IgniteServices services = ignite.services(ignite.cluster().forServers());
services.deployClusterSingleton("IgniteServiceTestInterface", new IgniteServiceTestImpl());

// Accessing the deployed service
IgniteServiceTestInterface cntrSvc = ignite.services()
    .serviceProxy("IgniteServiceTestInterface", IgniteServiceTestInterface.class, false);
System.out.println(cntrSvc.invokeNext(1));

org.apache.ignite.IgniteException：无法找到已部署的服务
