我创建了一个非常简单的Spring（无 Boot ）应用程序，我可以将其打包到.war中，并手动部署到Tomcat中，它可以正常工作。以下是我的项目：https://github.com/gaetan-l/demo-spring-api
现在我想在this github project之后使用嵌入式Tomcat，所以我添加了以下类：

package gaetanl.demo.springapi;

import java.io.File;
import java.util.Optional;
import org.apache.catalina.startup.Tomcat;

public class Application {
    public static final Optional<String> port = Optional.ofNullable(System.getenv("PORT"));

    public static void main(String[] args) throws Exception {
        String webappPath = "./build/libs";
        String warName = "demo-spring-api-1.0-SNAPSHOT";
        File war = new File(webappPath + "/" + warName + ".war");
        if (!war.exists()) {
            System.out.println("The .war has not been created yet (or is in another folder than ./build/libs)");
            System.out.println("Try running the gradle task \"assemble\"");
            return;
        }

        Tomcat tomcat = new Tomcat();
        tomcat.setPort(Integer.valueOf(port.orElse("8080") ));

        // Tomcat base directory
        tomcat.setBaseDir("./tomcat.8080");

        // Application root for this Host, can be an absolute pathname, a
        // relative pathname, or a URL.
        tomcat.getHost().setAppBase("./work/Tomcat/localhost");

        // Adding a web application to a host's appBase (usually Tomcat's
        // webapps directory).
        tomcat.addWebapp("/" + warName, war.getCanonicalPath());

        tomcat.start();
        tomcat.getServer().await();
    }
}

.war在嵌入式Tomcat的webapp文件夹中正确解压缩，然后当我运行Application类时，服务器似乎正确启动，下面是控制台输出：

16:09:07: Executing ':Application.main()'...

但是我无法访问服务器，当我尝试执行curl.exe -v http：//localhost：8080/时，我得到以下答案：

*   Trying 127.0.0.1:8080...
*   Trying [::1]:8080...
* connect to 127.0.0.1 port 8080 failed: Connection refused
* connect to ::1 port 8080 failed: Connection refused
* Failed to connect to localhost port 8080 after 2252 ms: Couldn't connect to server
* Closing connection 0

当我try netstat -an | find "8080"它也找不到任何东西。我做错什么了吗？
