java - BufferedReader readLine 和 OutputStreamWriter .write

Question

我有 2 个程序:客户端和服务器。

服务器创建一个 ServerSocket，客户端使用以下方式连接:

address = InetAddress.getByName(host);
conn = new Socket(address, port);

这是可行的，但问题是:void mousePressed() { 一旦单击鼠标就会被调用，执行以下命令:(客户端)

void mousePressed() {
  try {
    BufferedOutputStream os = new BufferedOutputStream(conn.getOutputStream());
    OutputStreamWriter osw = new OutputStreamWriter(os, "US-ASCII");
    osw.write("123");
        osw.flush();
      } catch (Exception e) {
        e.printStackTrace();
      }
}

服务器应该使用以下方式接收输入:

BufferedReader reader = new BufferedReader(
new InputStreamReader(new BufferedInputStream(conn.getInputStream())));
StringBuilder result = new StringBuilder();
for (String line = null; (line = reader.readLine()) != null;) {
    result.append(line);
}
reader.close();
println(result.toString());

服务器仅在客户端使用 conn.close(); 关闭套接字或退出客户端后才接收输入。由于我希望能够多次单击鼠标，因此无法关闭套接字。

如何在不关闭套接字的情况下发送输入？

编辑:连接代码:

服务器:

 // init
    ServerSocket socket1;
    int main_port = 5204;
    // in main
    try {
          socket1 = new ServerSocket(main_port);
          Socket conn = socket1.accept();
        } catch (Exception e) {
            e.printStackTrace();
        }

客户:

// init
    String host = "localhost";
    int port = 5204;
    Socket conn;
    InetAddress address;
    // in main
    try {
          address = InetAddress.getByName(host);
          conn = new Socket(address, port);
         } catch (Exception e) {
                e.printStackTrace();
            }

Answer 1

我的解决方案(基于其他答案和评论):

1) 在客户端中将 osw.write("123"); 更改为 osw.write("123\n");。

2)更换

    BufferedReader reader = new BufferedReader(new InputStreamReader(new
BufferedInputStream(thread_cnn.getInputStream())));        
        StringBuilder result = new StringBuilder();
        for (String line = null; (line = reader.readLine()) != null;) {
    result.append(line);
}
println(result);
reader.close();

与

BufferedReader reader = new BufferedReader(new InputStreamReader(new BufferedInputStream(conn.getInputStream())));        
String result = reader.readLine().toString();
println(result);
reader = null;
result = null;

在服务器上。
