Starting and Stopping an Embedded Jetty Server

Ahoy there, mateys! In this article, we’ll be discussing how to start and stop an Embedded Jetty Server. Embedded Jetty is a lightweight and fast web server that can be embedded in Java applications. It’s a great choice for developers who need to create web applications that can be run locally or as part of a larger system.

Starting an Embedded Jetty Server

Starting an Embedded Jetty Server is easy as pie. First, you need to create a new instance of the Server class. Here’s some code to get you started:

Server server = new Server(8080);

This creates a new server instance and specifies that it should listen on port 8080. You can change the port number to whatever value you like. Once you’ve created the server instance, you’ll need to add a Handler to it. A handler is responsible for processing incoming requests and returning responses.

Handler handler = new AbstractHandler() {
    public void handle(String target, Request baseRequest, HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException {
        response.setContentType("text/html;charset=utf-8");
        response.setStatus(HttpServletResponse.SC_OK);
        baseRequest.setHandled(true);
        response.getWriter().println("<h1>Hello, world!</h1>");
    }
};
server.setHandler(handler);

This code creates a simple Handler that returns a “Hello, world!” message when a request is received. The setHandler() method sets this handler as the default handler for the server.

Finally, you need to start the server:

server.start();

This starts the server and begins listening for incoming requests. That’s it! Your Embedded Jetty Server is now up and running.

Stopping an Embedded Jetty Server

Stopping an Embedded Jetty Server is just as simple. You can use the stop() method to stop the server:

server.stop();

This method stops the server and releases any resources that it’s using. It’s important to always stop the server when you’re done using it, so that you don’t leave any open connections or waste system resources.

Conclusion

That’s all there is to starting and stopping an Embedded Jetty Server. It’s quick and easy to get up and running, and it provides a great foundation for building powerful web applications. In the next article, we’ll cover how to configure an Embedded Jetty Server. Until then, happy coding, me hearties!
