使用 DeployTask 类远程部署 war 文件的 Java 代码

Question

我编写了下面的代码，使用 Tomcat 已经实现的 DeployTask 类在 tomcat 服务器上远程部署 war 文件。

import java.io.File;
import org.apache.catalina.ant.DeployTask;

public class TestClass {
    public static void main(String[] args) {
        String filePath = "resources/StudentWS.war";
        TestClass test=new TestClass();
        ClassLoader classLoader = test.getClass().getClassLoader();
        File warFile = new       
        File(classLoader.getResource(filePath).getFile());

        String webPath="StudentWS";
        String url = "http://localhost:8080/manager/text";

        DeployTask deployTask=new DeployTask();
        deployTask.setUrl(url);
        deployTask.setUsername("deployer");
        deployTask.setPassword("admin");       
        deployTask.setWar(warFile.getAbsolutePath());
        deployTask.setPath(webPath);
        deployTask.execute();
    }
}

这是 tomcat 上用户部署器的配置:

 < role rolename="manager-script"/>

 < role rolename="manager-jmx"/>

 < user username="deployer" password="admin" roles="manager-script,manager-jmx"/>

但是我得到了以下错误:

Exception in thread "main" java.io.IOException: Error writing request body to server

我想知道我错过了什么，或者是否有一个 java 代码可以在不使用 maven 的情况下使用下面的 url 远程部署 war 文件:

http://localhost:8080/manager/text/deploy?path=/StudentWS&war=file:Path_To_War_File

Answer 1

我刚刚遇到了同样的问题。问题似乎是我们需要使用“localwar”属性。我查看了源代码，它对 war 属性的处理方式不同，无法使用该属性部署本地文件。将您的代码更改为:

DeployTask deployTask=new DeployTask();
deployTask.setUrl(url);
deployTask.setUsername("deployer");
deployTask.setPassword("admin");       
deployTask.setLocalWar(warFile.getAbsolutePath());
deployTask.setPath(webPath);
deployTask.execute();

更新

我刚刚意识到这只有在您要部署到的服务器是本地服务器时才有效。如果它是远程服务器，我不相信它会起作用。 Deploy 任务本身一定有问题导致它失败。
