Java CRUDEPository未在CommandLineRunner中保存数据

我试图在应用程序通过commandlinerunner启动时添加一些默认数据，但Crudepository的.save函数没有保存数据。我曾在另一个commandlinerunner中尝试过，效果很好。我不确定这节课有什么问题。感谢您的帮助

我运行的另一个类具有以下控制台输出

Hibernate: insert into user (name, role, id) values (?, ?, ?)
Saved user:User [name=jyj123, id=1, role=Admin]

这个不起作用的类显示Hibernate:insert****和Hibernate:Select****

CommandLineRunner类

@Component
public class FlightsRepositoryCommandLineRunner implements CommandLineRunner {

    @Autowired
    private FlightsRepository flightsRep;
    
    @Override
    public void run(String... args) throws Exception {
        DateFormat df = new SimpleDateFormat("yyyy-MM-dd");
        Date d1 = df.parse("2020-12-10");
        Date d2 = df.parse("2020-12-11");
        Flights flights = new Flights("SQ404", "SIN", "LAX", "2045", "2140", "15h 55min", "Singapore Airlines", "$1050", d1, d2, false);
        flightsRep.save(flights);
        Date d3 = df.parse("2021-01-01");
        Date d4 = df.parse("2021-01-02");
        Flights flights1 = new Flights("UA356", "LAX", "SIN", "0045", "0940", "21h 30min", "United Airlines", "$941", d3, d4, false);
        flightsRep.save(flights1);
        Date d5 = df.parse("2020-09-15");
        Date d6 = df.parse("2020-09-16-");
        Flights flights2 = new Flights("EM544", "SIN", "LAX", "2045", "2140", "20h 35min", "Emirates", "$591", d5, d6, false);
        flightsRep.save(flights2);
        Date d7 = df.parse("2020-12-25");
        Date d8 = df.parse("2020-12-26");
        Flights flights3 = new Flights("SQ501", "SIN", "LAX", "2045", "2140", "19h 45min", "Singapore Airlines", "$1203", d7, d8, false);
        flightsRep.save(flights3);
        Date d9 = df.parse("2020-10-10");
        Date d10 = df.parse("2020-10-11");
        Flights flights4 = new Flights("MA403", "LAX", "SIN", "1945", "2340", "14h 55min", "Malaysia Airlines", "$2102", d9, d10, false);
        flightsRep.save(flights4);
    }

您可以发布错误跟踪吗？您也可以从哪里知道它没有保存，而不是

CommandLineRunner

您也可以尝试

ApplicationRunner

？会发生错误吗？您是否已启用日志以查看hibernate操作？@Patrick控制台没有编写hibernate:saved***@AvijitBarua没有错误，只是没有保存
