Scala调用jetty的jar包

huhahapz

　　需要将jar包放到scala安装目录的lib（如C:\Program Files\scala\lib）目录下，则使用scalac和scala编译运行时可以不用添加包依赖关系。
　　如Java使用jetty库实现服务器如下(demo/Hello.java)：

package demo;
import org.eclipse.jetty.server.*;
import org.eclipse.jetty.server.handler.HandlerCollection;
import org.eclipse.jetty.server.nio.SelectChannelConnector;  
import org.eclipse.jetty.servlet.ServletContextHandler;
import org.eclipse.jetty.util.thread.QueuedThreadPool;
public class Hello{
public static void main(String[] args) throws Exception {
Server server = new Server();
//Handler
SelectChannelConnector connector = new SelectChannelConnector();  
connector.setPort(1987);  
connector.setThreadPool(new QueuedThreadPool(5));
server.setConnectors(new Connector[]{connector});
ServletContextHandler handlercontext = new ServletContextHandler();  
handlercontext.setContextPath("/");  
server.setHandler(handlercontext);  
HandlerCollection hc =new HandlerCollection();
hc.setHandlers(new Handler[]{handlercontext});
server.setHandler(hc);
server.start();
server.join();
}
}
　　使用scala调用jetty*.jar包如下：

//webapp
import org.eclipse.jetty.server._;
import org.eclipse.jetty.webapp._;
object Hello {   
def main(args: Array[String]) {
var webapp = "D:\\htdocs\\1";
val server = new Server(80);
val context = new WebAppContext(webapp,"/");
server.setHandler(context);
server.start();
server.join();
}
}
//handler
import org.eclipse.jetty.server._;
import org.eclipse.jetty.server.handler.HandlerCollection;
import org.eclipse.jetty.server.nio.SelectChannelConnector;  
import org.eclipse.jetty.servlet.ServletContextHandler;
import org.eclipse.jetty.util.thread.QueuedThreadPool;
object Hello {   
def main(args: Array[String]) {
val server = new Server();
//Handler
val connector = new SelectChannelConnector();  
connector.setPort(1987);
connector.setThreadPool(new QueuedThreadPool(5));
val connectors = new Array[Connector](1);
connectors(0) = connector;
server.setConnectors(connectors);
val handlercontext = new ServletContextHandler();  
handlercontext.setContextPath("/");  
server.setHandler(handlercontext);  
val hc =new HandlerCollection();
val contexts = new Array[Handler](1);
contexts(0) = handlercontext;
hc.setHandlers(contexts);
server.setHandler(hc);
server.start();
server.join();
}
}
