j2ee打造可执行war包

1.  下载jetty

注意： Jetty 9.x 需要 JDK 1.7 支持。下表是Jetty各版本状态一览。

版本	JDK版本	Servlet	JSP	状态
9.0	1.7	3.0 (3.1 on branch)	2.2	稳定
8.x	1.6	3.0	2.2	成熟
7.x	1.5, J2ME	2.5	2.1	成熟
6.x	1.4-1.5	2.5	2.0	过时

下载地址： http://download.eclipse.org/jetty/

2.   启动类

package net.codaview;

import java.io.File;
import java.net.URL;
import java.security.ProtectionDomain;

import org.eclipse.jetty.server.Server;
import org.eclipse.jetty.webapp.WebAppContext;

public class EmbeddedServer {

    public static void main(String[] args) throws Exception {
        int port = Integer.parseInt(System.getProperty("port", "8080"));
        Server server = new Server(port);

        ProtectionDomain domain = EmbeddedServer.class.getProtectionDomain();
        URL warLocation = domain.getCodeSource().getLocation();

        WebAppContext webapp = new WebAppContext();
        webapp.setContextPath("/");
        webapp.setDescriptor(warLocation.toExternalForm() + "/WEB-INF/web.xml");
        webapp.setServer(server);
        webapp.setWar(warLocation.toExternalForm());
        String tempDir = new File(warLocation.getPath()).getParent() + "/tmp";
        webapp.setTempDirectory(new File(tempDir));

        server.setHandler(webapp);
        server.start();
        server.join();
    }
}

3.   ant脚本

<project>
    <target name="war">
        <!-- web根路径 -->
        <property name="webapp.dir" location="${basedir}/webapp" />
        <!-- jetty  -->
