Tomcat:以编程方式远程部署服务

Question

我正在尝试创建一个在tomcat服务器上部署WAR文件的服务。该类将input作为WAR文件的路径，并在run中的类包含以下代码后自动将其部署到tomcat服务器。请帮我解决这个问题。

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：

你的目标是在tomcat上部署war。我建议使用maven。如果你已经在你的项目中使用了maven，那么就使用tomcat插件。它将为您创建一个war并将其部署到tomcat上。

假设您使用的是Tomcat7。在pom.xml的<build>标记中添加以下内容。

     <build>
        <finalName>AutohostDemo1_1145</finalName>
        <plugins>
            <plugin>
                <groupId>org.apache.tomcat.maven</groupId>
                <artifactId>tomcat7-maven-plugin</artifactId>
                <version>2.2</version>
                <configuration>
                    <url>http://localhost:8080/manager/text</url>
                    <server>TomcatServer</server>
                    <path>/AutohostDemo1_1145</path>
                </configuration>
            </plugin>
        </plugins>
    </build>

让你的tomcat保持运行。从存储库中获取所有最新代码。然后从项目的根目录(包含pom.xml文件的目录)运行以下命令。

mvn tomcat7:redeploy

此命令将创建一个war文件并将其部署到tomcat。我们甚至不需要手动重启tomcat。

如果要在远程服务器上执行此操作，则可以在服务器上克隆存储库一次。之后，无论何时需要在tomcat上部署新的war，都可以使用telnet进行连接&从项目的根目录(在远程服务器上)运行相同的命令。
