java.io.StreamCorruptedException：无效的流标题：54657374
我正在尝试读取一个使用Socket程序从客户端发送的字符串，代码如下：
import java.io.IOException; import java.io.ObjectInputStream; import java.io.ObjectOutputStream; import java.lang.ClassNotFoundException; import java.net.ServerSocket; import java.net.Socket; public class SocketServerExample { //static ServerSocket variable private static ServerSocket server; //socket server port on which it will listen private static int port = 5000; public static void main(String args[]) throws IOException, ClassNotFoundException{ //create the socket server object server = new ServerSocket(port); //keep listens indefinitely until receives 'exit' call or program terminates while(true){ System.out.println("Waiting for client request"); //creating socket and waiting for client connection Socket socket = server.accept(); //read from socket to ObjectInputStream object ObjectInputStream ois = new ObjectInputStream(socket.getInputStream()); //convert ObjectInputStream object to String String message = (String) ois.readObject(); System.out.println("Message Received: " + message); //create ObjectOutputStream object ObjectOutputStream oos = new ObjectOutputStream(socket.getOutputStream()); //write object to Socket oos.writeObject("Hi Client "+message); //close resources ois.close(); oos.close(); socket.close(); //terminate the server if client sends exit request if(message.equalsIgnoreCase("exit")) break; } System.out.println("Shutting down Socket server!!"); //close the ServerSocket object server.close(); } } 但是从客户端读取字符串时，我收到如下错误：
Exception in thread "main" java.io.StreamCorruptedException: invalid stream header: 54657374 at java.io.ObjectInputStream.readStreamHeader(ObjectInputStream.java:803) at java.io.ObjectInputStream.(ObjectInputStream.java:298) at SocketServerExample.main(SocketServerExample.java:29)
我搜索并没有管理找到错误。 请帮帮我。
显然，您不是使用ObjectOutputStream:发送数据ObjectOutputStream:您只是在编写字节。
- 如果使用
readObject()读取，则必须使用writeObject().编写writeObject(). - 如果使用
readUTF()读取，则必须使用writeUTF().写入writeUTF(). - 如果使用
readXXX()读取，readXXX()必须使用writeXXX(),写入大多数XXX值。
您不能指望ObjectInputStream自动将文本转换为对象。 hex54657374作为文本"Test" 。 您必须直接以字节发送它。
