在Java Socket使用TCP的基础上，通过ObjectInputStream和ObjectOutputStream来读写对象。

//传输的对象，需要序列化

package socket;

public class MsgTO implements Serializable

{

private static final long serialVersionUID = 1L;

private String msg;

private int status;

private String response;

public String getMsg() {

return msg;

}

public void setMsg(String msg) {

this.msg = msg;

}

public int getStatus() {

return status;

}

public void setStatus(int status) {

this.status = status;

}

public String getResponse() {

return response;

}

public void setResponse(String response) {

this.response = response;

}

}

//客户端

public class SocketClient

{

private final Logger logger = LoggerFactory.getLogger(getClass());
