使用配置文件控制定时任务的注解

@Component
@EnableScheduling
@PropertySource("classpath:config/sftp.properties")
public class TimedTask {
    @Resource
    private SFTPProp sftpProp;
    @Resource
    private SaveImpl save;

    @Scheduled(cron = "${timedTask}")
    public void downloadTask() {
        System.out.println("定时任务自动启动，当前时间：" + new Date());
        System.out.println("IP：" + sftpProp.getIP());
        System.out.println("Port：" + sftpProp.getPort());
        System.out.println("Username：" + sftpProp.getUsername());
        System.out.println("Password：" + sftpProp.getPassword());
        System.out.println("remoteDownloadDir：" + sftpProp.getRemoteDownloadDir());
　　}
}

@PropertySource("classpath:config/sftp.properties")

@Scheduled(cron = "${timedTask}")

在使用jar包运行程序时，会读取不到外部配置，将配置文件名改为application.properties后问题解决
