如何用java 程序启动Apache-ftpserver 功能

Answer 1

public class FtpServerListener implements ServletContextListener {

public static final String FTPSERVER_CONTEXT_NAME = "org.apache.ftpserver";

public void contextDestroyed(ServletContextEvent sce) {
System.out.println("Stopping FtpServer");

FtpServer server = (FtpServer) sce.getServletContext().getAttribute(FTPSERVER_CONTEXT_NAME);

if(server != null) {
server.stop();

sce.getServletContext().removeAttribute(FTPSERVER_CONTEXT_NAME);

System.out.println("FtpServer stopped");
} else {
System.out.println("No running FtpServer found");
}

}

public void contextInitialized(ServletContextEvent sce) {
System.out.println("Starting FtpServer");

WebApplicationContext ctx = WebApplicationContextUtils.getWebApplicationContext(sce.getServletContext());

FtpServer server = (FtpServer) ctx.getBean("myFtpServer");

sce.getServletContext().setAttribute(FTPSERVER_CONTEXT_NAME, server);

try {
server.start();
System.out.println("FtpServer started");
} catch (Exception e) {
throw new RuntimeException("Failed to start FtpServer", e);
}
}

}
