使用内部 RESTlet 服务器的 RESTlet 应用程序上下文为空
我有一个 Restlet (2.0.10) 应用程序，我从以下代码开始：
public static void main(final String[] args) {
try {
// Create a new Component
final Component component = new Component();
// Add a new HTTP server listening on port 8182
component.getServers().add(Protocol.HTTP, SERVER_PORT);
// Add a client protocol connector for static files
component.getClients().add(Protocol.FILE);
// Attach the sample application.
component.getDefaultHost().attach("/myApp", new MyApplication(Context.getCurrent()));
// Start the component.
component.start();
} catch (Exception e) {
LOGGER.error(e);
}
}
现在我需要应用程序内的应用程序根目录（即 /myApp），我尝试根据 Java 从 Restlet 资源中访问 ServletContext：
Client serverDispatcher = context.getServerDispatcher();
ServletContext servletContext = (ServletContext)serverDispatcher.getContext().getAttributes()
.get("org.restlet.ext.servlet.ServletContext");
String contextPath = servletContext.getContextPath();
将我的应用程序部署到Tomcat 服务器，但是当我使用如上所示的组件启动服务器时，我的 Context 始终为空。有人可以告诉我如何使用 Restlet 内部服务器功能获取正确初始化的上下文吗？
I have a Restlet (2.0.10) application, I start with the following code:
public static void main(final String[] args) {
try {
// Create a new Component
final Component component = new Component();
// Add a new HTTP server listening on port 8182
component.getServers().add(Protocol.HTTP, SERVER_PORT);
// Add a client protocol connector for static files
component.getClients().add(Protocol.FILE);
// Attach the sample application.
component.getDefaultHost().attach("/myApp", new MyApplication(Context.getCurrent()));
// Start the component.
component.start();
} catch (Exception e) {
LOGGER.error(e);
}
}
Now I require the applications root (i.e. /myApp) inside the application and I try to get this according to Java accessing ServletContext from within restlet Resource:
Client serverDispatcher = context.getServerDispatcher();
ServletContext servletContext = (ServletContext)serverDispatcher.getContext().getAttributes()
.get("org.restlet.ext.servlet.ServletContext");
String contextPath = servletContext.getContextPath();
This works perfectly fine while deploying my application to a Tomcat Server, but as soon as I start the server using a Component as shown above, my Context is always null. Can someone please tell me how to get a properly initialized context using restlets internal server capabilities?

看起来逻辑。
您需要 servlet 上下文，但您没有在 servlet 容器中运行，因此 servlet 上下文为 NULL。
当执行 component.start() 时，您使用 Restlet 连接器来服务器 HTTP/HTTPS 请求，而不是像 Tomcat 这样的 servlet 容器。
Seems logic.
You want a servlet context but you are not running in a servlet container, so the servlet context is NULL.
When doing component.start() you are using the Restlet connectors to server HTTP/HTTPS requests, not a servlet container like Tomcat.
您需要从
Component类中获取上下文：这只会为您提供 Restlet 上下文，但 Servlet 上下文仍然不可用，因为这是一个独立的 Java 应用程序。
You would need to pick up the context from the
ComponentClass:That would just give you the Restlet context, but Servlet Context still won't be available since this is a standalone Java application.
