只能使用@Scheduled注釋無引數方法

@Component
public class SaveProviderStartupRunner implements ApplicationRunner {

    @Autowired
    private ProviderController providerController;

    @Autowired
    private AttachmentEmail attachmentEmail;

    String fileDate1 = new SimpleDateFormat("dd.MM.yyyy").format(new Date());

    LocalDate today = LocalDate.now();
    String fileDate = (today.minusDays(1)).format(DateTimeFormatter.ofPattern("dd MMM"));
    String fileDate2 = (today.minusMonths(1)).format(DateTimeFormatter.ofPattern("MMM"));

    @Override
    public void run(ApplicationArguments args) throws Exception {
        providerController.saveCards();
    }

    //@Override
    @Scheduled(cron = "26 17 * * * *")
    public void run1(ApplicationArguments args) throws Exception {
        attachmentEmail.sendMail1("[email protected]", "[email protected]", "List for "   fileDate, " ", "Report "   fileDate1   ".xlsx");
        attachmentEmail.sendMail2("[email protected]", "[email protected]", "List for "   fileDate, " ", "Report1 "   fileDate1   ".xlsx");
        attachmentEmail.sendMail3("[email protected]", "[email protected]", "List for "   fileDate, " ", "Report2 "   fileDate1   ".xlsx");
    }

    @Scheduled(cron = "27 17 * * * *")
    public void run2(ApplicationArguments args) throws Exception {
        attachmentEmail.sendMail4("[email protected]", "[email protected]", "List for "   fileDate, " ", "Report3 "   fileDate1   ".xlsx");
        attachmentEmail.sendMail5("[email protected]", "[email protected]", "List for "   fileDate, " ", "Report4 "   fileDate1   ".xlsx");
        attachmentEmail.sendMail6("[email protected]", "[email protected]", "List for "   fileDate, " ", "Report5 "   fileDate1   ".xlsx");
    }

    @Scheduled(cron = "28 17 * * * *")
    public void run3(ApplicationArguments args) throws Exception {
        attachmentEmail.sendMail7("[email protected]", "[email protected]", "List for "   fileDate, " ", "Report6 "   fileDate1   ".xlsx");
        attachmentEmail.sendMail8("[email protected]", "[email protected]", "List for "   fileDate, " ", "Report7 "   fileDate1   ".xlsx");
        attachmentEmail.sendMail9("[email protected]", "[email protected]", "List for "   fileDate, " ", "Report8 "   fileDate1   ".xlsx");
    }
}

我的專案有一種方法可以開始保存到 .xlsx 檔案。首先，我想將它們分開，以便一次保存一些檔案，另一次保存其他檔案。我嘗試設定此方法以通過 Scheduled 運行

@Override
@Scheduled(cron = "10 10 * * * *")
public void run(ApplicationArguments args) throws Exception {
    providerController.saveCards();
}

但是，我得到一個錯誤，因為在我有（args）的方法的引數中，沒有它這個方法不起作用。如何設定調度程式以便按時呼叫我的方法？

uj5u.com熱心網友回復：

On run1()，run2()并且run3()您不需要 ，ApplicationArguments args因為唯一的方法實際上覆寫了ApplicationRunner.run(ApplicationArguments args)方法，因此只需洗掉它們。此外，我會保持簡單并簡單地將方法分開（一個覆寫ApplicationRunner.run(ApplicationArguments args)方法和一個被調度的方法）：

@Component
public class SaveProviderStartupRunner implements ApplicationRunner {

    @Autowired
    private ProviderController providerController;

    @Autowired
    private AttachmentEmail attachmentEmail;

    String fileDate1 = new SimpleDateFormat("dd.MM.yyyy").format(new Date());

    LocalDate today = LocalDate.now();
    String fileDate = (today.minusDays(1)).format(DateTimeFormatter.ofPattern("dd MMM"));
    String fileDate2 = (today.minusMonths(1)).format(DateTimeFormatter.ofPattern("MMM"));

    @Override
    public void run(ApplicationArguments args) throws Exception {
        providerController.saveCards();
    }

    @Scheduled(cron = "10 10 * * * *")
    public void run() throws Exception {
        providerController.saveCards();
    }

    @Scheduled(cron = "26 17 * * * *")
    public void run1() throws Exception {
        attachmentEmail.sendMail1("[email protected]", "[email protected]", "List for "   fileDate, " ", "Report "   fileDate1   ".xlsx");
        attachmentEmail.sendMail2("[email protected]", "[email protected]", "List for "   fileDate, " ", "Report1 "   fileDate1   ".xlsx");
        attachmentEmail.sendMail3("[email protected]", "[email protected]", "List for "   fileDate, " ", "Report2 "   fileDate1   ".xlsx");
    }

    @Scheduled(cron = "27 17 * * * *")
    public void run2() throws Exception {
        attachmentEmail.sendMail4("[email protected]", "[email protected]", "List for "   fileDate, " ", "Report3 "   fileDate1   ".xlsx");
        attachmentEmail.sendMail5("[email protected]", "[email protected]", "List for "   fileDate, " ", "Report4 "   fileDate1   ".xlsx");
        attachmentEmail.sendMail6("[email protected]", "[email protected]", "List for "   fileDate, " ", "Report5 "   fileDate1   ".xlsx");
    }

    @Scheduled(cron = "28 17 * * * *")
    public void run3() throws Exception {
        attachmentEmail.sendMail7("[email protected]", "[email protected]", "List for "   fileDate, " ", "Report6 "   fileDate1   ".xlsx");
        attachmentEmail.sendMail8("[email protected]", "[email protected]", "List for "   fileDate, " ", "Report7 "   fileDate1   ".xlsx");
        attachmentEmail.sendMail9("[email protected]", "[email protected]", "List for "   fileDate, " ", "Report8 "   fileDate1   ".xlsx");
    }
}
