简单的Client和Server的实现，传输对象流

（测试时，要先启动服务器端，再启动客户端，如果出现Connection reset的异常，说明Student类没有实现序列化。

为什么yaos要实现序列化呢？[https://blog.csdn.net/thinkingcao/article/details/75133183][https_blog.csdn.net_thinkingcao_article_details_75133183]

参考这篇博客）

**Server服务器端**

public class server {
    	public static void main(String[] args) throws Exception {
    		//1.创建服务器端套接字对象
    		ServerSocket ss=new ServerSocket(10098);
    		//2.创建兼听客户端socket
    		Socket socket = ss.accept();
    		//3.使用流接收
    		InputStream is = socket.getInputStream();
    		BufferedInputStream bis = new BufferedInputStream(is);
    		ObjectInputStream ois = new ObjectInputStream(bis);
    		System.out.println("我服务器端要开始接收了哈！");
    		Student stu=(Student)ois.readObject();
    		String string = stu.toString();
    		System.out.println(socket.getInetAddress().getHostAddress()+":"+string);
    		//4.关闭流
    		socket.close();
    		ss.close();
    	}
    }

**Client客户端**

public class client {
    	public static void main(String[] args) throws Exception {
    		Student stu=new Student();
    		stu.setName("静静");
    		stu.setWord("今天天气真好啊！");
    		//1.创建客户端套接字对象
    		Socket s=new Socket("127.0.0.1",10098);
    		//2.使用流写
    		OutputStream os = s.getOutputStream();
    		BufferedOutputStream bos = new BufferedOutputStream(os);
    		ObjectOutputStream oos = new ObjectOutputStream(bos);
    		System.out.println("客户端开始传输数据了！");
    		oos.writeObject(stu);
    		//3.关闭流
    		oos.close();
    		bos.close();
    		os.close();
    		s.close();
    	}
    }

**Student实体类**

//实体类要进行序列化
    public class Student implements Serializable{
    	private String name;
    	private String word;
    	public String getName() {
    		return name;
    	}
    	public void setName(String name) {
    		this.name = name;
    	}
    	public String getWord() {
    		return word;
    	}
    	public void setWord(String word) {
    		this.word = word;
    	}
    	public Student(String name, String word) {
    		super();
    		this.name = name;
    		this.word = word;
    	}
    	public Student() {
    		super();
    	}
    	@Override
    	public String toString() {
    		return "Student [name=" + name + ", word=" + word + "]";
    	}
    }
