无法设置TimeofDay的值，它始终为null

import java.time.LocalTime;

public class Main {
    public static void main(String[] args) {
        LocalTime timeOfDay = LocalTime.of(10, 30); // 设置时间为上午10:30
        System.out.println(timeOfDay);
    }
}

import java.time.LocalTime;

public class Main {
    public static void main(String[] args) {
        LocalTime timeOfDay = null;
        timeOfDay = LocalTime.of(10, 30); // 初始化并设置时间为上午10:30
        System.out.println(timeOfDay);
    }
}

import java.time.LocalTime;

public class Main {
    public static void main(String[] args) {
        LocalTime timeOfDay = getTimeOfDay();
        System.out.println(timeOfDay);
    }

    public static LocalTime getTimeOfDay() {
        // 确保这里正确设置了时间
        return LocalTime.of(10, 30);
    }
}

import org.springframework.format.annotation.DateTimeFormat;

public class Event {
    @DateTimeFormat(pattern = "HH:mm")
    private LocalTime timeOfDay;

    public void setTimeOfDay(LocalTime timeOfDay) {
        this.timeOfDay = timeOfDay;
    }

    public LocalTime getTimeOfDay() {
        return timeOfDay;
    }
}
