我們可以通過ManagerServlet中g(shù)etPathInfo()提供的操作，將自己的項(xiàng)目遠(yuǎn)程部署到服務(wù)器上，下面將貼出我的實(shí)踐代碼，在實(shí)踐它之前你只需要引入httpclient包和commons包。

測(cè)試遠(yuǎn)程部署
在測(cè)試之前請(qǐng)先在配置文件放通下面用戶權(quán)限：
<role rolename="admin-gui"/> <role rolename="admin-script"/> <role rolename="manager-gui"/> <role rolename="manager-script"/> <role rolename="manager-jmx"/> <role rolename="manager-status"/> <user username="sqdyy" password="123456" roles="manager-gui,manager-script,manager-jmx,manager-status,admin-script,admin-gui"/>
下面是測(cè)試成功遠(yuǎn)程部署war包的代碼：
import static org.testng.AssertJUnit.assertEquals;
import java.io.File;
import java.net.URL;
import org.testng.annotations.Test;
public class TestTomcatManager {
@Test
public void testDeploy() throws Exception {
TomcatManager tm = new TomcatManager(new URL("http://localhost:8080/manager/text"), "sqdyy", "123456");
File war = new File("E:\\tomcat\\simple-war-project-1.0-SNAPSHOT.war");
TomcatManagerResponse response = tm.deploy("/simple-war-project-1.0-SNAPSHOT", war, true);
System.out.println(response.getHttpResponseBody());
assertEquals(200, response.getStatusCode());
// output:
// OK - Deployed application at context path /simple-war-project-1.0-SNAPSHOT
}
@Test
public void testList() throws Exception {
TomcatManager tm = new TomcatManager(new URL("http://localhost:8080/manager/text"), "sqdyy", "123456");
TomcatManagerResponse response = tm.list();
System.out.println(response.getHttpResponseBody());
assertEquals(200, response.getStatusCode());
// output:
// OK - Listed applications for virtual host localhost
// /:running:0:ROOT
// /simple-war-project-1.0-SNAPSHOT:running:0:simple-war-project-1.0-SNAPSHOT
// /examples:running:0:examples

// /docs:running:0:docs
}
@Test
public void testServerinfo() throws Exception {
TomcatManager tm = new TomcatManager(new URL("http://localhost:8080/manager/text"), "sqdyy", "123456");
TomcatManagerResponse response = tm.serverinfo();
System.out.println(response.getHttpResponseBody());
assertEquals(200, response.getStatusCode());
