Java shutdown http server after receiving request-CodePudding

I have a setup a simple http server in java that only deals with one type of post request.

The server code:

int port = 5555;
HttpServer server = HttpServer.create(new InetSocketAddress(port), 0);
System.out.println("server started at "   port);
server.createContext("/echoPost", new echoPost());
server.setExecutor(null);
server.start();

The echoPost() class:

public class echoPost implements HttpHandler {

    @Override
    public void handle(HttpExchange http) throws IOException {  
            
            
            InputStreamReader inputStreamReader = new InputStreamReader(http.getRequestBody(), "utf-8");
            BufferedReader bufferReader = new BufferedReader(inputStreamReader);
            String incoming = br.readLine();
            System.out.println(incoming);                         
            
            String response = "response";
            
            http.sendResponseHeaders(200, response.length());
            OutputStream outputStream = http.getResponseBody();
            os.write(response.toString().getBytes());
            os.close();
            
    }
}

I want the server to stop after a post request is received. Is there a way to do this so straight after one post request is handled the server stops?

CodePudding user response：

What's wrong with calling server.stop(delay), where the delay is small enough (0 or 1)? You'll need to pass server as argument to the echoPost constructor.

CodePudding user response：

Use

System.exit(0);

It doesn't matter where this line of code is executed, it will terminate the JVM and quit.
