使用 maven 为 Spring MVC 和 jetty 嵌入式项目创建可执行战争

Question

我正在尝试为带有嵌入式码头的 Spring MVC 项目进行可执行的战争。我想使用命令 java -jar myProject.war 运行战争并启动主类。我只想使用 maven-war-plugin 但它不起作用

这是类 MAin

public class Main
{
	public static void main(String... anArgs) throws Exception
    {
        new Main().start();
    }

	private WebServer server;
    
    public Main()
    {
        server = new WebServer(8024);        
    }
    
    public void start() throws Exception
    {
        server.start();
        server.join();
    }
}

这是 WebServerClass

Answer 1

您需要maven assembly plugin。

首先在你的项目中嵌入jetty并配置Spring的DispatcherServlet。

import org.eclipse.jetty.server.Server;
import org.eclipse.jetty.servlet.ServletContextHandler;

public class App {

    public static void main( String[] args ) throws Exception {

        int port = 8080;

        Server server = new Server(port);
        ServletContextHandler handler = new ServletContextHandler(ServletContextHandler.SESSIONS);
        handler.setContextPath("/");
        server.setHandler(handler);
        handler.addServlet(org.springframework.web.servlet.DispatcherServlet.class, "/");
        server.start();
        server.join();

    }
}

然后使用组装插件创建一个可运行的jar

<build>
  <plugins>
    <plugin>
      <artifactId>maven-assembly-plugin</artifactId>
      <configuration>
        <archive>
          <manifest>
            <mainClass>fully.qualified.MainClass</mainClass>
          </manifest>
        </archive>
        <descriptorRefs>
          <descriptorRef>jar-with-dependencies</descriptorRef>
        </descriptorRefs>
      </configuration>
    </plugin>
  </plugins>
</build>

最后执行mvn clean compile assembly:single
