java.io.StreamCorruptedException: invalid stream header: 异常

使用java的对象流出现java.io.StreamCorruptedException: invalid stream header异常

原因是数据发送端发送对象到接收端

接收端对于同一个输入流创建了不同的对象输入流，而后用不同的对象输入流进行接收

下面模拟异常的发送

传输的对象：

 

public class User implements Serializable{
	private String name;
	private int age;
	public User(String name, int age){
		this.name = name;
		this.age = age;
	}
	public String GetName(){
		return this.name;
	}
	public int GetAge(){
		return this.age;
	}
}

 

客户端程序：

 

public class Client {
	public static void main(String[] args) throws Exception {
		Socket client = new Socket("127.0.0.1", 1234);
		ObjectOutputStream objOutput = new ObjectOutputStream(client.getOutputStream());
		//用同一输出流发送两个对象
		User user = new User("小明", 20);
		objOutput.writeObject(user);
		User user1 = new User("小红", 10);
		objOutput.writeObject(user1);
		client.close();
	}
}

 

 

 

服务端：

 

public class Server {

	public static void main(String[] args) throws Exception {
		// TODO Auto-generated method stub
		ServerSocket serverSocket = new ServerSocket(1234);
		
		System.out.println("start. . .");
		Socket clientSocket = serverSocket.accept();
		
		//用clientSocket的输入流创建对象输入流objInput
		ObjectInputStream objInput = new ObjectInputStream(clientSocket.getInputStream());
		User user = (User)objInput.readObject();
		System.out.println(user.GetName());
		System.out.println(user.GetAge());
		
		//用clientSocket的输入流创建对象输入流objInput2
		ObjectInputStream objInput2 = new ObjectInputStream(clientSocket.getInputStream());
		user = (User)objInput2.readObject();
		System.out.println(user.GetName());
		System.out.println(user.GetAge());	
		
		
		clientSocket.close();
		serverSocket.close();
	}

}

服务端用网络输入流创建了两个不同的对象输入流，这时就会产生异常，如果用同一个对象输入流接收就不会产生。
