ningyu1 opened a new issue #1768: When the RPC protocol is HTTP, use GenericService.$invoke call error. URL: https://github.com/apache/incubator-dubbo/issues/1768 ## dubbo version dubbo-2.6.1 ## provider service ``` public interface MyClassService { public String sayHello(); public String sayHello(MyClassVo vo, @Min(1) long id); } ``` ## provider config ``` <dubbo:application name="dubbo-test-main" /> <!-- <dubbo:registry address="N/A" /> --> <dubbo:registry protocol="zookeeper" address="192.168.0.58:2181"/> <dubbo:protocol port="8090" name="http" /> <dubbo:service protocol="http" interface="com.jiuyescm.dubbo.test.api.MyClassService" ref="myClassService"/> ``` ## consumer use registry ``` ApplicationConfig application = new ApplicationConfig(); application.setName("DubboSample"); ReferenceConfig reference = new ReferenceConfig(); reference.setApplication(application); RegistryConfig registry = registry = new RegistryConfig(); registry.setProtocol("zookeeper"); registry.setAddress("192.168.0.58:2181"); reference.setRegistry(registry); reference.setGeneric(true); GenericService genericService = (GenericService) reference.get(); Object result = genericService.$invoke(getMethod(), new String[]{}, new Object[]{}); ``` ## consumer use dircet connection ``` ApplicationConfig application = new ApplicationConfig(); application.setName("DubboSample"); ReferenceConfig reference = new ReferenceConfig(); reference.setApplication(application); reference.setUrl("http://192.168.6.47:8090/com.jiuyescm.dubbo.test.api.MyClassService";) reference.setGeneric(true); GenericService genericService = (GenericService) reference.get(); Object result = genericService.$invoke(getMethod(), new String[]{}, new Object[]{});
