java之接口开发-初级篇-socket通信

socket通信实现util包类实现

public class SocketThread extends Thread {
public void run() {
while (true) {
// log4j
Logger log = (Logger) LogManager.getLogger(SocketThread.class);
// 标识服务信息
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS");
ServerSocket ss;// socket服务监听对象
Socket socket;// 获取监听得到的结果
BufferedReader in;// 输入流
PrintWriter out;// 输出流
try {
// 设置监听的端口，并实例监听对象
ss = new ServerSocket(SocketConstants.SOCKET_PORT_NO_EC);
while (true) {

// 开始监听，若没有客户端请求则线程一直停留在这里等待请求，
// 一旦就有请求，就获取监听到的对象
socket = ss.accept();

InputStream sis = socket.getInputStream();// socket服务获取的输入流

// 等待读取状态
// 大于零为获取完毕
while (sis.available() <= 0)
System.out.println("inputStream is waitting...");

in = new BufferedReader(new InputStreamReader(sis));// 获取输入

String line = "";// 监听到的字符串

// 读数据
while (in.ready()) {
line += in.readLine();
}
// 记录下获取到的字符串流
log.warn("client request is :" + line);
out = new PrintWriter(socket.getOutputStream(), true);// 构建输出

// 输出
out.println("server response " + sdf.format(new Date()));
// 关闭当前请求对象
out.close();
in.close();
socket.close();
