Question

我有一个简单的Restlet应用程序，当它作为一个来自Eclipse的J2SE应用程序运行时工作正常，但是当打包为战争并使用＆＃34; mvn jetty运行时：run-war＆＃34; （jetty-maven-plugin），Application.createInboundRoot方法不会被调用，因此没有配置路由。

相关的错误消息似乎是

WARNING: A filter was executed without a next Restlet attached to it.

您可以从控制台输出中看到，在J2SE情况下调用ModspaceRestletApplication.createInboundRoot，在J2EE情况下，不调用该方法。为什么不呢？

以J2SE（Eclipse-＆gt; Run As-＆gt; Java Application）运行。

点击网址进行测试：

http://localhost:8182/modspace/users/fred/entries

返回正确形成的响应，控制台输出为：

In ModspaceRestApplication.ctor
Mar 25, 2014 2:41:15 PM org.restlet.engine.http.connector.HttpServerHelper start
INFO: Starting the internal HTTP server on port 8182
In ModspaceRestApplication.createInboundRoot

使用＆＃39; mvn jetty从命令行运行战争：run-war＆＃34;。

点击网址进行测试：

http://localhost:8080/modspace/users/fred/entries

浏览器看到了

The server encountered an unexpected condition which prevented it from fulfilling the request

和控制台输出是：

Restlet应用程序类：

import org.restlet.Application;
import org.restlet.Component;
import org.restlet.Restlet;
import org.restlet.data.Protocol;
import org.restlet.routing.Router;

public class ModspaceRestletApplication extends Application {

    Router router;

    public ModspaceRestletApplication() {
        System.out.println("In ModspaceRestApplication.ctor");
        //this.setInboundRoot(this.createInboundRoot());
    }

    @Override
    public synchronized Restlet createInboundRoot() {
        // Create a root router
        router = new Router(getContext());

        System.out.println("In ModspaceRestApplication.createInboundRoot");

        // Attach the handlers to the root router
        router.attach("/users/{user}", UserResource.class);
        router.attach("/users/{user}/entries", ModelResource.class);

        return router;
    }

        // Create a new Restlet component and add a HTTP server connector to it
        Component component = new Component();
        component.getServers().add(Protocol.HTTP, 8182);

        // Then attach it to the local host
        component.getDefaultHost().attach("/modspace", new ModspaceRestletApplication());

        // Now, let's start the component!
        // Note that the HTTP server connector is also automatically started.
        component.start();
    }
}

这现在有效。我认为这个问题是由于：

<dependency>
  <groupId>org.restlet</groupId>
  <artifactId>org.restlet.ext.servlet</artifactId>
  <version>2.0-M3</version>
</dependency>

应该是：

<dependency>
  <groupId>org.restlet.jee</groupId>
  <artifactId>org.restlet.ext.servlet</artifactId>
  <version>2.2.0</version>
</dependency>

注意groupID错误且版本已旧。

当app作为Eclipse / J2SE运行而不是作为maven jetty运行时调用的Restlet createInboundRoot：run-war
