Java实现简单的socket通信教程
作者：liushao
这篇文章主要介绍了Java实现简单的socket通信教程，具有很好的参考价值，希望对大家有所帮助。一起跟随小编过来看看吧
今天学习了一下java如何实现socket通信，感觉难点反而是在io上，因为java对socket封装已经很完善了。
今天代码花了整个晚上调试，主要原因是io的flush问题和命令行下如何运行具有package的类，不过最后问题基本都解决了，把代码贴出来供大家参考
server
public class TcpServer {
public static void main(String[] args) throws Exception {
ServerSocket server = new ServerSocket(9091);
try {
Socket client = server.accept();
try {
BufferedReader input =
new BufferedReader(new InputStreamReader(client.getInputStream()));
boolean flag = true;
int count = 1;
while (flag) {
System.out.println(客户端要开始发骚了，这是第 + count + 次！);
count++;
String line = input.readLine();
System.out.println(客户端说： + line);
if (line.equals(exit)) {
flag = false;
System.out.println(客户端不想玩了！);
} else {
System.out.println(客户端说： + line);
}
}
} finally {
client.close();
}
} finally {
server.close();
}
}
}
client
public class TcpClient {
public static void main(String[] args) throws Exception {
Socket client = new Socket(127.0.0.1, 9091);
try {
PrintWriter output =
new PrintWriter(client.getOutputStream(), true);
Scanner cin = new Scanner(System.in);
String words;
while (cin.hasNext()) {
words = cin.nextLine();
output.println(words);
System.out.println(写出了数据: + words);
}
cin.close();
} finally {
client.close();
}
}
}
补充知识：Java-Socket通信 同时JSON传递与解析

return ID;

ID = iD;
