It's a simple example of using HttpServer.
package java_httpserver; import com.sun.net.httpserver.HttpExchange; import com.sun.net.httpserver.HttpHandler; import com.sun.net.httpserver.HttpServer; import java.io.IOException; import java.io.OutputStream; import java.net.InetSocketAddress; import java.util.logging.Level; import java.util.logging.Logger; /** * * @web http://java-buddy.blogspot.com/ */ public class Java_HttpServer { public static void main(String[] args) { try { HttpServer httpServer = HttpServer.create(new InetSocketAddress(8000), 0); httpServer.createContext("/", new MyHttpHandler()); httpServer.setExecutor(null); httpServer.start(); } catch (IOException ex) { Logger.getLogger(Java_HttpServer.class.getName()).log(Level.SEVERE, null, ex); } } static class MyHttpHandler implements HttpHandler{ @Override public void handle(HttpExchange he) throws IOException { int responseCode_OK = 200; String response = "Hello from java-buddy"; he.sendResponseHeaders(responseCode_OK, response.length()); OutputStream outputStream = he.getResponseBody(); outputStream.write(response.getBytes()); outputStream.close(); //try-with-resources form /* try (OutputStream outputStream = he.getResponseBody()) { outputStream.write(response.getBytes()); } */ } } }
To access the server, open a browser and visit: http://localhost:8000/
Next example show how to implement HttpServer to download image.
