Jetty在多个TCP端口上发布端点

我们正在使用Jetty 9.3嵌入式和发布多个Web服务端点(使用Endpoint.publish)。但我不确定如何在不同的TCP端口上发布其中一些。

端点发布:

endpoint = Endpoint.publish("http://0.0.0.0:8081/services/Service1"), service1);
endpoint = Endpoint.publish("http://0.0.0.0:8081/services/Service2"), service2);
endpoint = Endpoint.publish("http://0.0.0.0:8082/services/Service3"), service3);

期待:使端口8081上的服务1和2可用,端口8082上只有8081和Service3,而且只有8082。

实际:两个TCP端口都可用的所有三种服务。

设置使用我们的嵌入式码头:

JettyHttpServerProvider.setServer(jettyWebServer);
System.setProperty("com.sun.net.httpserver.HttpServerProvider", JettyHttpServerProvider.class.getName());

为了完整性,jetty web server init:

jettyWebServer = new Server(new DelegatingThreadPool(new QueuedThreadPool()));
ServerConnector connector = new ServerConnector(jettyWebServer);
//connector.setHost();
connector.setPort(8081);
jettyWebServer.addConnector(connector);

不得不为第二个端口添加此端点,端点发布将不适用于Service3:

connector = new ServerConnector(jettyWebServer);
//connector.setHost(...);
connector.setPort(8082);
jettyWebServer.addConnector(connector);
ContextHandlerCollection contexts = new ContextHandlerCollection();
jettyWebServer.setHandler(contexts);

但是这三个端口8081和8082都可以使用。无法设置多个jetty服务器实例来处理这个问题,只有一套方法可用:JettyHttpServerProvider.setServer(...),没有添加或类似

任何帮助表示感谢。

我能够通过创建两个Jetty Server实例并使用不同的实例设置全局JettyHttpServerProvider.server静态字段来实现此功能,如下所示:

package com.scotth.jettypublish;

import javax.xml.ws.Endpoint;

import org.eclipse.jetty.http.spi.DelegatingThreadPool;
import org.eclipse.jetty.http.spi.JettyHttpServerProvider;
import org.eclipse.jetty.server.Server;
import org.eclipse.jetty.server.ServerConnector;
import org.eclipse.jetty.server.handler.ContextHandlerCollection;
import org.eclipse.jetty.util.thread.QueuedThreadPool;

import com.scotth.jettypublish.ws.HelloWorld;
import com.scotth.jettypublish.ws.impl.HelloWorldImplOne;
import com.scotth.jettypublish.ws.impl.HelloWorldImplThree;
import com.scotth.jettypublish.ws.impl.HelloWorldImplTwo;

public class PublishTesterMain {

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

        Server ws1 = new Server(new DelegatingThreadPool(new QueuedThreadPool()));
        ServerConnector connector = new ServerConnector(ws1);
        connector.setPort(8081);
        ws1.addConnector(connector);
        ContextHandlerCollection contexts = new ContextHandlerCollection();
        ws1.setHandler(contexts);

        Server ws2 = new Server(new DelegatingThreadPool(new QueuedThreadPool()));
        ServerConnector connector2 = new ServerConnector(ws2);
        connector2.setPort(8082);
        ws2.addConnector(connector2);
        ContextHandlerCollection contexts2 = new ContextHandlerCollection();
        ws2.setHandler(contexts2);

        System.setProperty("com.sun.net.httpserver.HttpServerProvider", JettyHttpServerProvider.class.getName());

        HelloWorld service1 = new HelloWorldImplOne();
        HelloWorld service2 = new HelloWorldImplTwo();

        JettyHttpServerProvider.setServer(ws1);
        Endpoint.publish("http://0.0.0.0:8081/services/Service1", service1);
        Endpoint.publish("http://0.0.0.0:8081/services/Service2", service2);
        ws1.start();

        HelloWorld service3 = new HelloWorldImplThree();

        JettyHttpServerProvider.setServer(ws2);
        Endpoint.publish("http://0.0.0.0:8082/services/Service3", service3);
        ws2.start();
        Thread.sleep(Long.MAX_VALUE);
    }

}

运行这个主要方法后,我观察到以下印刷标准:

2016-05-31 22:38:54.818:INFO::main: Logging initialized @212ms

2016-05-31 22:38:55.942:INFO:oejs.Server:main: Started @1339ms

请求http://localhost:8081/services/Service1http://localhost:8081/services/Service2产生了预期的Web服务端点问候页面,而http://localhost:8081/services/Service3产生了HTTP 404。请求http://localhost:8082/services/Service3产生了预期的第三个服务端点问候页面。

要完成代码示例(如果您已经有可用的服务impl对象,则没有必要),这是我使用的服务端点接口(三个impls的相同接口):

package com.scotth.jettypublish.ws;

import javax.jws.WebMethod;
import javax.jws.WebService;

@WebService
public interface HelloWorld {

    @WebMethod 
    String sayHello(String name);
}

以下是演示的Endpoint.publish()调用中使用的三种Web服务实现:

一:

package com.scotth.jettypublish.ws.impl;

import javax.jws.WebService;

import com.scotth.jettypublish.ws.HelloWorld;

@WebService(endpointInterface = "com.scotth.jettypublish.ws.HelloWorld")
public class HelloWorldImplOne implements HelloWorld {

    @Override
    public String sayHello(String name) {
        return "ONE Hello " + (name == null ? "World" : name);
    }

}

二:

package com.scotth.jettypublish.ws.impl;

import javax.jws.WebService;

import com.scotth.jettypublish.ws.HelloWorld;

@WebService(endpointInterface = "com.scotth.jettypublish.ws.HelloWorld")
public class HelloWorldImplTwo implements HelloWorld {

    @Override
    public String sayHello(String name) {
        return "TWO Hello " + (name == null ? "World" : name);
    }

}

三:

package com.scotth.jettypublish.ws.impl;

import javax.jws.WebService;

import com.scotth.jettypublish.ws.HelloWorld;

@WebService(endpointInterface = "com.scotth.jettypublish.ws.HelloWorld")
public class HelloWorldImplThree implements HelloWorld {

    @Override
    public String sayHello(String name) {
        return "THREE Hello " + (name == null ? "World" : name);
    }

}
