Question

我尝试使用jetty和javax-rs创建其他服务器。我指的是一些网站的内容。

https://www.javacodegeeks.com/2015/03/creating-web-services-and-a-rest-server-with-jax-rs-and-jetty.html

我只是有一些问题。 1.如果我想制作它，我是否必须运行tomcat或者只是使用Jetty？

我想为WebSocket和rest服务器设置configure。这意味着不仅要使用rest服务器，还要使用websocket。我不知道如何设置使用两者。首先，我成功制作了Web套接字服务器。

我想知道下面两个不同代码的合并。

我的服务器主要用于使用websocket（它被引用到这个网站http://amilamanoj.blogspot.kr/2013/06/secure-websockets-with-jetty.html）

import org.eclipse.jetty.http.HttpVersion;
import org.eclipse.jetty.server.*;
import org.eclipse.jetty.server.handler.ContextHandler;
import org.eclipse.jetty.server.handler.HandlerCollection;
import org.eclipse.jetty.util.resource.FileResource;
import org.eclipse.jetty.util.resource.Resource;
import org.eclipse.jetty.util.ssl.SslContextFactory;
import org.eclipse.jetty.websocket.server.WebSocketHandler;
import org.eclipse.jetty.websocket.servlet.WebSocketServletFactory;

import java.util.ArrayList;
import java.util.List;

public class WebSocketServer {
    private Server server;
    private String host;
    private int port;
    private Resource keyStoreResource;
    private String keyStorePassword;
    private String keyManagerPassword;
    private List<Handler> webSocketHandlerList = new ArrayList<>();

    public static void main(String[] args) throws Exception {
        WebSocketServer webSocketServer = new WebSocketServer();
        webSocketServer.setHost("localhost");
        webSocketServer.setPort(8443);
        webSocketServer.setKeyStoreResource(new FileResource(WebSocketServer.class.getResource("/keystore.jks")));
        webSocketServer.setKeyStorePassword("password");
        webSocketServer.setKeyManagerPassword("password");
        webSocketServer.addWebSocket(MyWebSocket.class, "/");
        webSocketServer.initialize();
        webSocketServer.start();
    }

    public void initialize() {
        server = new Server();
        // connector configuration
        SslContextFactory sslContextFactory = new SslContextFactory();
        sslContextFactory.setKeyStoreResource(keyStoreResource);
        sslContextFactory.setKeyStorePassword(keyStorePassword);
        sslContextFactory.setKeyManagerPassword(keyManagerPassword);
        SslConnectionFactory sslConnectionFactory = new SslConnectionFactory(sslContextFactory, HttpVersion.HTTP_1_1.asString());
        HttpConnectionFactory httpConnectionFactory = new HttpConnectionFactory(new HttpConfiguration());
        ServerConnector sslConnector = new ServerConnector(server, sslConnectionFactory, httpConnectionFactory);
        sslConnector.setHost(host);
        sslConnector.setPort(port);
        server.addConnector(sslConnector);
        // handler configuration
        HandlerCollection handlerCollection = new HandlerCollection();
        handlerCollection.setHandlers(webSocketHandlerList.toArray(new Handler[0]));
        server.setHandler(handlerCollection);
    }

    public void addWebSocket(final Class<?> webSocket, String pathSpec) {
        WebSocketHandler wsHandler = new WebSocketHandler() {
            @Override
            public void configure(WebSocketServletFactory webSocketServletFactory) {
                webSocketServletFactory.register(webSocket);
            }
        };
        ContextHandler wsContextHandler = new ContextHandler();
        wsContextHandler.setHandler(wsHandler);
        wsContextHandler.setContextPath(pathSpec);  // this context path doesn't work ftm
        webSocketHandlerList.add(wsHandler);
    }

    public void start() throws Exception {
        server.start();
        server.join();
    }
    public void stop() throws Exception {
        server.stop();
        server.join();
    }

    public void setHost(String host) {
        this.host = host;
    }
    public void setPort(int port) {
        this.port = port;
    }
    public void setKeyStoreResource(Resource keyStoreResource) {
        this.keyStoreResource = keyStoreResource;
    }
    public void setKeyStorePassword(String keyStorePassword) {
        this.keyStorePassword = keyStorePassword;
    }
    public void setKeyManagerPassword(String keyManagerPassword) {
        this.keyManagerPassword = keyManagerPassword;
    }

}

这是运行Rest Server的配置。

package example;
import org.eclipse.jetty.server.Server;4
import org.eclipse.jetty.servlet.ServletContextHandler;

import org.eclipse.jetty.servlet.ServletHolder;

public class RestServer {

    public static void main(String[] args) throws Exception {

        ServletContextHandler context = new ServletContextHandler(ServletContextHandler.SESSIONS);

        context.setContextPath("/");



        Server jettyServer = new Server(8080);

        jettyServer.setHandler(context);



        ServletHolder jerseyServlet = context.addServlet(

                org.glassfish.jersey.servlet.ServletContainer.class, "/*");

        jerseyServlet.setInitOrder(0);



        jerseyServlet.setInitParameter(

                "jersey.config.server.provider.classnames",

                Calculator.class.getCanonicalName());
        try {

            jettyServer.start();

            jettyServer.join();

        } finally {

            jettyServer.destroy();

        }

    }

}

我是否需要Tomcat使用Jetty开发Servlet（休息服务器）？
