Ich habe WebAppContext in der Hauptklasse und ich habe ein Servlet, die WebServlet Annotation und Konstruktor mit Argumenten haben. Wie kann ich Argumente von der Hauptklasse an Servlet übergeben?WebAppContext übergeben Argument zu Servlet Konstruktor
Main.java:
String webappDirLocation = "src/main/java/frontend/webapp/";
WebAppContext webAppContext = new WebAppContext();
webAppContext.setResourceBase("public_html");
webAppContext.setContextPath("/");
webAppContext.setDescriptor(webappDirLocation + "WEB-INF/web.xml");
webAppContext.setConfigurations(new Configuration[]{
new AnnotationConfiguration(), new WebXmlConfiguration(),
new WebInfConfiguration(),
new PlusConfiguration(),
new MetaInfConfiguration(),
new FragmentConfiguration(),
new EnvConfiguration()}
);
webAppContext.setAttribute("org.eclipse.jetty.server.webapp.ContainerIncludeJarPattern", ".*/classes/.*");
webAppContext.setParentLoaderPriority(true);
web.xml:
<?xml version="1.0" encoding="UTF-8"?>
<web-app

Servlets:
@WebServlet(name = "WebSocketGameServlet", urlPatterns = {"/gameplay"})
public class WebSocketGameServlet extends WebSocketServlet {
static final Logger logger = LogManager.getLogger(GameWebSocket.class);
private final static int IDLE_TIME = 6000 * 1000;
private AccountService accountService;
private Game game;
private WebSocketService webSocketService;
public WebSocketGameServlet(AccountService accountService, Game game, WebSocketService webSocketService) {
this.accountService = accountService;
this.game = game;
this.webSocketService = webSocketService;
}
@Override
public void configure(WebSocketServletFactory factory) {
factory.getPolicy().setIdleTimeout(IDLE_TIME);
factory.setCreator(new GameWebSocketCreator(accountService, game, webSocketService));
}
}
Sie sollten EJB Injection verwenden, da Sie sich für IoC entschieden haben (Inversion der Kontrolle). –
