java.lang.NoClassDefFoundError:org/omg/CORBA/COMM_创建简单spring boor rmi应用程序时客户端出现故障
我正在使用服务器上的RmiServiceExporter和客户端上的RmiProxyFactoryBean创建spring引导应用程序java.lang.NoClassDefFoundError:org/omg/CORBA/COMM_创建简单spring boor rmi应用程序时客户端出现故障,java,spring,spring-boot,spring-remoting,Java,Spring,Spring Boot,Spring Remoting,我正在使用服务器上的RmiServiceExporter和客户端上的RmiProxyFactoryBean创建spring引导应用程序 [main] o.s.remoting.rmi.RmiServiceExporter: Binding service 'ServerServiceIF' to RMI registry: RegistryImpl[UnicastServerRef [liveRef: [endpoint:[localhost:1099](local),objID:[0:0:0,

然后我启动我的客户端,它也是spring boot应用程序,客户端上的服务接口连接到本地主机上的地址
rmi://localhost:1099/ServerServiceIF
但当我尝试调用这个接口的方法时,我得到了

以下是我的服务器和客户端:
ServerApplication.java
package com.cw.server;
import com.cw.appif.ServerServiceIF;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;

@SpringBootApplication
public class ServerApplication {
@Bean
ServerServiceIF serverServiceIF() {
return new ServerService();
}
@Bean
RmiServiceExporter exporter(ServerServiceIF implementation) {
// Expose a service via RMI. Remote object URL is:
// rmi://<HOST>:<PORT>/<SERVICE_NAME>
// 1099 is the default port
Class<ServerServiceIF> serviceInterface = ServerServiceIF.class;
RmiServiceExporter exporter = new RmiServiceExporter();
exporter.setServiceInterface(serviceInterface);
exporter.setService(implementation);
exporter.setServiceName(serviceInterface.getSimpleName());
exporter.setRegistryPort(1099);
return exporter;
}
public static void main(String[] args) {
SpringApplication.run(ServerApplication.class, args);
}
package com.cw.client;

user = new User("Denis","1234","e@mail.co");
service.auth(user);
System.out.println("User authed");
} catch (AuthException e) {
e.printStackTrace();
}
}
}
我的服务器服务接口和服务器上的实现:
package com.cw.appif;
import com.cw.exceptions.AuthException;
import com.cw.models.User;
public interface ServerServiceIF{
boolean auth(User user) throws AuthException;
}
package com.cw.server;
import com.cw.appif.ServerServiceIF;
import com.cw.exceptions.AuthException;
import com.cw.models.User;
import java.util.List;
public class ServerService implements ServerServiceIF{
static List<User> clients;
@Override
public boolean auth(User user) throws AuthException {
clients.add(user);
System.out.println("hi");
return true;
}
}
package com.cw.appif;
导入com.cw.exceptions.AuthException;
导入com.cw.models.User;
公共接口ServerServiceIF{
布尔身份验证(用户用户)抛出身份验证异常;
}
包com.cw.server;
导入com.cw.appif.ServerServiceIF;
导入com.cw.exceptions.AuthException;
导入com.cw.models.User;
导入java.util.List;
公共类ServerService实现ServerServiceIF{
静态列表客户端;
@凌驾
公共布尔身份验证(用户用户)引发身份验证异常{
clients.add(用户);
System.out.println(“hi”);
返回true;
}
}
我的想法如下:
1) 可能是因为我在客户端和服务器上使用的接口完全相同,但客户端找不到类,因为路径不同
2) 当我调试我的客户端服务->h->advised->targetSource->targetClass时为空。可以吗?我将在下面的调试中上传我的项目结构和这个变量的截图
找到了问题。在将corba添加到类路径之后,我发现类用户必须是可序列化的。添加
实现了Serializable
和serialVersionUID
解决了这个问题,现在一切都正常了。如果您使用的是Java 9,您必须将Corba类添加到类路径中。哦,我明白了。但据我所知,我不能使用corba异常。我将添加它并更新帖子
