以编程方式在tomcat上部署Web服务

Question

我正在尝试提供一项将在雄猫服务器上部署WAR文件的服务。 该类将输入作为WAR文件的路径，并在运行以下代码后将其自动部署到tomcat服务器。 请帮助我。 我也不想使用SFTP上传WAR，而是使用put请求将WAR文件部署在tomcat上。 我已经看到了使用FTP或SFTP的示例，但这不是我所需要的。 我的服务已经托管在tomcat上，它将自动托管提供给它的WAR文件。

public class DeployManager {

static CredentialsProvider credsProvider = new BasicCredentialsProvider();;

public static void main(String args[]) throws ClientProtocolException, IOException {
    /*
     * warning only ever AuthScope.ANY while debugging with these settings
     * the tomcat username and pw are added to EVERY request
     */

    credsProvider.setCredentials(AuthScope.ANY, new UsernamePasswordCredentials("tomcat", "s3cret"));
    deploy();
    // undeploy();
}

private static void deploy() throws ClientProtocolException, IOException {
    String url = "http://localhost:8080/manager/text/deploy?path=C:/Users/Jainesh_Trivedi/Desktop/WAR/AutohostDemo1_1145.war";
    File file = new File("C:\\Users\\Jainesh_Trivedi\\Desktop\\WAR\\AutohostDemo1_1145.war");

    HttpPut req = new HttpPut(url);
    MultipartEntityBuilder meb = MultipartEntityBuilder.create();
    meb.addTextBody("Sample", "C:\\Users\\Jainesh_Trivedi\\Desktop\\WAR\\AutohostDemo1_1145.war");

    // "application/octect-stream"
    meb.addBinaryBody("attachment", file, ContentType.APPLICATION_OCTET_STREAM, file.getName());

    req.setEntity(meb.build());
    String response = executeRequest(req, credsProvider);

    System.out.println("Response : " + response);
}

public static void undeploy() throws ClientProtocolException, IOException {
    String url = "http://localhost:8080/manager/text/undeploy?path=/deployMe";
    HttpGet req = new HttpGet(url);
    String response = executeRequest(req, credsProvider);
    System.out.println("Response : " + response);
}

private static String executeRequest(HttpRequestBase requestBase, CredentialsProvider credsProvider)
        throws ClientProtocolException, IOException {
    CloseableHttpClient client = HttpClients.custom().setDefaultCredentialsProvider(credsProvider).build();
    InputStream responseStream = null;
    String res = null;
    HttpResponse response = client.execute(requestBase);
    HttpEntity responseEntity = response.getEntity();
    responseStream = responseEntity.getContent();

    BufferedReader br = new BufferedReader(new InputStreamReader(responseStream));
    StringBuilder sb = new StringBuilder();
    String line;
    while ((line = br.readLine()) != null) {
        sb.append(line);
        sb.append(System.getProperty("line.separator"));
    }
    br.close();
    res = sb.toString();

    return res;
}
}

错误是：
