java - 查找尝试连接到 ServerSocket 的程序的 IP

Question

虽然我搜索了它，但我找不到答案。

假设我有以下 Java 代码：

    ServerSocket serve = null;

    try {
        server = new ServerSocket(5567);
    } catch (IOException e) {
        System.err.println("Problem with port 5567");
        System.exit(1);
    }

    Socket clientSocket = null;
    try {
        clientSocket = server.accept();
    } catch (IOException e) {
        System.exit(1);
    }

何时server.accept()被调用程序会阻塞，直到有人连接到我的服务器。有没有办法能够找到连接到我的服务器的程序/用户的 IP？

尝试

Socket clientSocket = null;
    try {
        clientSocket = server.accept();
        System.out.println("Connected from " + clientSocket .getInetAddress() + " on port "
             + clientSocket .getPort() + " to port " + clientSocket .getLocalPort() + " of "
             + clientSocket .getLocalAddress());
    } catch (IOException e) {
        System.exit(1);
    }
