我有部署有关Ignite服务一个实用程序方法:在Apache部署服务的Ignite
private static void startNewService(String queryId, String sqlQuery, long timeInterval) {
QueryServiceImpl cepService = new QueryServiceImpl(queryId, sqlQuery, timeInterval);
ServiceConfiguration cfg = new ServiceConfiguration();
cfg.setService(cepService);
cfg.setName(queryId);
cfg.setTotalCount(1);
cfg.setMaxPerNodeCount(1);
System.out.println("---- Deploying the service. "+queryId);
services.deploy(cfg);
System.out.println("---- Deployed the service. "+queryId);
}
当我运行这个从我的客户端机器,我得到的服务器计算机以下错误:
[12:13:26,640][SEVERE][srvc-deploy-#35%myGrid%][GridServiceProcessor] Failed to initialize service (service will not be deployed): Query1

我的QueryServiceImpl实现Service,QueryService,其中QueryService是一个带有方法runContinuousQuery()的接口。
请注意,我没有手动将此jar /类复制到服务器类路径。我期待着点燃将所需的类加载到Ignite服务器节点并在那里运行服务。我怎样才能做到这一点?
如果每次更改都需要部署时,如何开发服务?即使使用本地Ignite服务器,我也遇到同样的问题。 – Derecho
