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>

public class TomcatManager extends AbstractCatalinaTask implements
ITomcatManager {
private String path = null;
/**
* deploy one web app with the given location of war .
*/
public void deploy(URL war, boolean update) {
DeployTask deployer = new DeployTask();
deployer.setPath(path);
deployer.setUsername(username);
deployer.setPassword(password);
deployer.setUrl(url);
deployer.setWar(war.toString());
deployer.setUpdate(update);
deployer.execute();
}
/**
*
* @param warFile
* @param update
* @throws MalformedURLException
*/
public void deploy(File warFile, boolean update)
throws MalformedURLException {
this.deploy(warFile.toURI().toURL(), update);
}
/**
* undeploy app
*/
public void undeploy() {
UndeployTask undeployer = new UndeployTask();
undeployer.setPath(path);
undeployer.setUrl(url);
undeployer.setUsername(username);
undeployer.setPassword(password);
undeployer.execute();
}
/**
* reload app.
*/
public void reload() {
ReloadTask reloader = new ReloadTask();
reloader.setPath(path);
reloader.setUrl(url);
reloader.setUsername(username);
reloader.setPassword(password);
reloader.execute();
}
/**
* start app by remotely
*/
public void start() {
StartTask starter = new StartTask();
starter.setPath(path);
starter.setUrl(url);
starter.setUsername(username);
starter.setPassword(password);
starter.execute();
}
/**
* stop the app
*/
public void stop() {
StopTask stopper = new StopTask();
stopper.setPath(path);
stopper.setUrl(url);
stopper.setUsername(username);
stopper.setPassword(password);
stopper.execute();
}
public String getPath() {
return path;
}
/**
* configure the context path of your web app.
*
* @param path
*/
public void setPath(String path) {
this.path = path;
}
}

调用方法已经在注释中给出了。
