嵌入式Tomcat Web服务器的使用

　　在运行web工程时，常常要频繁启动tomcat,使用嵌入式tomcat可以减少部分重复操作。

1、下载tomcat5.0.28embed.zip 解压文件夹复制到工程下。

　　http://archive.apache.org/dist/tomcat/tomcat-5/v5.0.28/bin/jakarta-tomcat-5.0.28-embed.zip

2、源码实现

import java.io.File;

import javax.servlet.ServletException;

import org.apache.catalina.LifecycleException;

import org.apache.catalina.core.AprLifecycleListener;

import org.apache.catalina.core.StandardServer;

import org.apache.catalina.startup.Tomcat;

import org.apache.juli.logging.Log;

import org.apache.juli.logging.LogFactory;



public class WebStart {

    private final Log log = LogFactory.getLog(getClass());

    private static String CONTEXT_PATH = "";

    private static String PROJECT_PATH = System.getProperty("user.dir");// 工程物理的绝对路径

    private static String WEB_APP_PATH = PROJECT_PATH + File.separatorChar

            + "WebRoot";

    private static String CATALINA_HOME = PROJECT_PATH + "/Embedded/Tomcat";

    private Tomcat tomcat = new Tomcat();

    private int port;



    public WebStart(int port) {

        this.port = port;

    }



    public void start(){

        tomcat.setPort(port);

        tomcat.setBaseDir(CATALINA_HOME);

        tomcat.getHost().setAppBase(WEB_APP_PATH);

        try {

            StandardServer server = (StandardServer) tomcat.getServer();

            AprLifecycleListener listener = new AprLifecycleListener();

            server.addLifecycleListener(listener);

            tomcat.addWebapp(CONTEXT_PATH, WEB_APP_PATH);

        } catch (ServletException e) {

            e.printStackTrace();

            log.error(e.getMessage());

        }

        try {

            tomcat.start();

            log.info("Tomcat started success !");

            tomcat.getServer().await();

        } catch (LifecycleException e) {

            e.printStackTrace();

            log.error(e.getMessage());

        }

    }



    public void stop(){

        try {

            tomcat.stop();

            log.info("Tomcat has stoped !");

        } catch (LifecycleException e) {

            e.printStackTrace();

            log.error(e.getMessage());

        }

    }



    public void setPort(int port) {

        this.port = port;

    }



    public int getPort() {

        return this.port;

    }



    public static void main(String[] args){

        WebStart tomcat = new WebStart(8080);

        try {

            tomcat.start();

        } catch (Exception e) {

            System.out.println("Tomcat Start error !"+"\n"+e.toString());

        }

    }
