Question

我想从官方文档中复制helloworld应用程序。我的应用程序称为Testapp，我是从org.opendaylight.controller groupId版本1.5.0创建的。添加示例代码（来自官方文档）并启动karaf后，我收到与databroker相关的错误。

我的TestappProvider.java

package org.opendaylight.testapp.impl;

    import   org.opendaylight.controller.sal.binding.api.BindingAwareBroker.ProviderContext ;
    import org.opendaylight.controller.sal.binding.api.BindingAwareBroker.RpcRegistration;
    import org.opendaylight.controller.sal.binding.api.BindingAwareProvider;
    import org.opendaylight.yang.gen.v1.urn.opendaylight.params.xml.ns.yang.testapp.rev170830.TestappService;
    import org.slf4j.Logger;
    import org.slf4j.LoggerFactory;

    public class TestappProvider implements BindingAwareProvider, AutoCloseable {

    private static final Logger LOG = LoggerFactory.getLogger(TestappProvider.class);
    private RpcRegistration<TestappService> helloService;

    @Override
    public void onSessionInitiated(ProviderContext session) {
        LOG.info("TestappProvider Session Initiated");
        helloService = session.addRpcImplementation(TestappService.class, new TestappImpl());
    }

    @Override
    public void close() throws Exception {
        LOG.info("TestappProvider Closed");
        if (helloService != null) {
            helloService.close();
        }
    }
}

我的TestappImpl

package org.opendaylight.testapp.impl;

import java.util.concurrent.Future;
import org.opendaylight.yang.gen.v1.urn.opendaylight.params.xml.ns.yang.testapp.rev170830.TestappService;
import org.opendaylight.yang.gen.v1.urn.opendaylight.params.xml.ns.yang.testapp.rev170830.HelloWorldInput;
import org.opendaylight.yang.gen.v1.urn.opendaylight.params.xml.ns.yang.testapp.rev170830.HelloWorldOutput;
import org.opendaylight.yang.gen.v1.urn.opendaylight.params.xml.ns.yang.testapp.rev170830.HelloWorldOutputBuilder;
import org.opendaylight.yangtools.yang.common.RpcResult;
import org.opendaylight.yangtools.yang.common.RpcResultBuilder;
public class TestappImpl implements TestappService {
@Override
public Future<RpcResult<HelloWorldOutput>> helloWorld(HelloWorldInput input) {
    HelloWorldOutputBuilder helloBuilder = new HelloWorldOutputBuilder();
    helloBuilder.setGreating("Hello " + input.getName());
    return RpcResultBuilder.success(helloBuilder.build()).buildFuture();
}
}

在Karaf中加载时发生ODL hello world应用程序错误
