java.lang.NoSuchMethodException：$ Proxy205.dispatch（int，my.package.beans.AdapterHeader，my.package.beans.AdapterInfo）

Question

有沒有人通過這個？

在服務器端，在我的OSGi應用程序中，我正在導出服務。這裏的春天文件代碼：

<!-- RMI SERVICE EXPORT --> 
<bean class="org.springframework.remoting.rmi.RmiServiceExporter"> 
    <property name="serviceName" value="IntegrationRemoteService" /> 
    <property name="service" ref="integrationExecutor" /> 
    <property name="serviceInterface" value="my.package.services.IntegrationService" /> 
    <property name="registryPort" value="$system{integration.port}" /> 
</bean> 

<!-- INTEGRATION EXECUTOR --> 
<bean id="integrationExecutor" class="my.package.engine.IntegrationServiceExecutor"> 
    <property name="integrationServiceImpl" ref="integrationEngine" />  
</bean> 

我IntegrationServiceExecutor類擴展IntegrationService接口和實現方法：

public class IntegrationServiceExecutor implements IntegrationService { 
... 
@Override 
public GenericResult dispatch(int serviceCode, AdapterHeader adapterHeader, AdapterInfo adapterInfo) { 

的IntegrationService接口是另一個組件定義，此相同的組件在我的.war使用在客戶端。在這部分，我也有遠程請求的執行，通過我的.war稱爲

... 
import org.springframework.aop.framework.ProxyFactory; 
import org.springframework.remoting.rmi.RmiProxyFactoryBean; 
... 

    public class GenericRmiFactory implements RemoteConnectionFactory { 

private ProxyFactory proxyFactory; 

public GenericRmiFactory(ServerTransport transport) throws ClassCastException, IllegalFormatException { 
    RmiServerTransport rmiTransport = (RmiServerTransport) transport; 

    RmiProxyFactoryBean rmiProxyFactoryBean = new RmiProxyFactoryBean(); 

    rmiProxyFactoryBean.setLookupStubOnStartup(false); 
    rmiProxyFactoryBean.setCacheStub(false); 
    rmiProxyFactoryBean.setRefreshStubOnConnectFailure(true); 
    rmiProxyFactoryBean.setServiceUrl(String.format("rmi://%s:%s/%s", rmiTransport.getHostname(), rmiTransport.getPort(), rmiTransport.getServiceName())); 
    rmiProxyFactoryBean.setServiceInterface(rmiTransport.getRemoteInterface()); 
    rmiProxyFactoryBean.afterPropertiesSet(); 

    this.proxyFactory = new ProxyFactory(rmiTransport.getRemoteInterface(), rmiProxyFactoryBean); 
} 

private ProxyFactory getproxyFactory() { 
    return proxyFactory; 
} 

@Override 
public Object getRemoteService() { 
    return getproxyFactory().getProxy(); 
} 
} 

我調用遠程服務以這樣的方式

... 
    IntegrationService integrationService = (IntegrationService) getGenericRemoteFactory().getRemoteService(); 
integrationService.dispatch(myInt, myAdapterHeader, myAdapterInfo); 
... 

最後這句話引發異常：

Invocation of method [public abstract my.package.result.GenericResult my.package.services.IntegrationService.dispatch(int,my.package.beans.AdapterHeader,my.package.beans.AdapterInfo)] failed in RMI service [rmi://127.0.0.1:2260/IntegrationRemoteService]; nested exception is java.lang.NoSuchMethodException: $Proxy205.dispatch(int, my.package.beans.AdapterHeader, my.package.beans.AdapterInfo) 

有什麼我在這裏失蹤？ 在此先感謝， 凱倫

我以前見過這個。你必須添加'throws RemoteException'到你的接口方法。客戶端拋出一個NoSuchMethodException，但它真的抱怨沒有RemoteException。
