好的,下面是一个简单的例子,展示了如何在QT和Java之间进行RPC通信,并传递结构体:
在QT中,创建一个包含结构体的远程对象并将其公开为服务:
```cpp
// MyObject.h
#include
struct MyStruct {
QString name;
int age;
};
class MyObject : public QObject
{
Q_OBJECT
public:
explicit MyObject(QObject *parent = nullptr);
signals:
void mySignal(MyStruct data);
MyStruct myMethod(MyStruct data);
};
```
```cpp
// MyObject.cpp
#include "MyObject.h"
MyObject::MyObject(QObject *parent) : QObject(parent)
{
}
MyStruct MyObject::myMethod(MyStruct data)
{
emit mySignal(data);
data.name = "Hello from QT!";
data.age += 1;
return data;
}
```
在Java中,创建一个包含结构体的客户端对象并使用RMI注册该对象:
```java
// MyClient.java
import java.rmi.Remote;
import java.rmi.RemoteException;
public interface MyClient extends Remote {
MyStruct myMethod(MyStruct data) throws RemoteException;
}
class MyStruct implements java.io.Serializable {
public String name;
public int age;
}
```
```java
// MyClientImpl.java
import java.rmi.RemoteException;
import java.rmi.server.UnicastRemoteObject;
public class MyClientImpl extends UnicastRemoteObject implements MyClient {
protected MyClientImpl() throws RemoteException {
super();
}
@Override
public MyStruct myMethod(MyStruct data) throws RemoteException {
System.out.println("Received data: " + data.name + ", " + data.age);
data.name = "Hello from Java!";
data.age += 1;
return data;
}
}
```
```java
// MyServer.java
import java.rmi.registry.LocateRegistry;
import java.rmi.registry.Registry;
public class MyServer {
public static void main(String[] args) {
try {
Registry registry = LocateRegistry.createRegistry(1099);
MyClientImpl client = new MyClientImpl();
registry.rebind("MyClient", client);
System.out.println("Java RMI server is running...");
} catch (Exception e) {
System.err.println("Java RMI server
