Tomcat 程序中远程部署

Tomcat远程部署：

tomcat提供了一套ant部署方案，但是项目中需要从程序中进行构件的远程部署，因此研究了一下tomcat的源码，给了一个简单的方案：
对于远端Tomcat服务器的配置：

1.修改远端tomcat的conf/tomcat-users.xml文件，添加manager角色，将其中一个用户设为manager角色

 <role rolename="manager"/>
 <user username="tomcat" password="tomcat" roles="tomcat,manager"/>

2.访问http://ip:port/,如果能通过tomcat/tomcat进入管理平台就证明你成功了]

程序代码如下:
接口:

package org.daragon.tomcat.manager;

import java.net.URL;

/**
 * 
 * @author daragon
 * 
 */
public interface ITomcatManager {

	public void deploy(URL war, boolean update);

	public void undeploy();

	public void reload();

	public void start();

	public void stop();
}

实现类：

package org.daragon.tomcat.manager;

import java.io.File;
import java.net.MalformedURLException;
import java.net.URL;

import org.apache.catalina.ant.AbstractCatalinaTask;
import org.apache.catalina.ant.DeployTask;
import org.apache.catalina.ant.ReloadTask;
import org.apache.catalina.ant.StartTask;
import org.apache.catalina.ant.StopTask;
import org.apache.catalina.ant.UndeployTask;

/**
 * Tomcat Deploy Manager <br>
 * Description : The Class {@link TomcatManager} is used to deploy your war file
 * remotely. and also, it can also undeploy,reload, start and stop your app. by
 * default, the user must have do as the role of manager on tomcat. you can
 * change that in <em>%CATALINA_HOME%/conf/tomcat-users.xml</em>
 * 
 * <em>Example:</em> 1. this will deploy a web app in tomcat. <code>
 * 		TomcatManager manager = new TomcatManager();
 * 		manager.setUsername("tomcat");
 * 		manager.setPassword("tomcat");
 * 		manager.setPath("/myapp");
 * 		manager.setUrl("http://ip:port/manager");
 * 		manager.deploy(new File("/home/daragon/myapp.war"),true);
 * </code>
 *

调用方法已经在注释中给出了。
