根据当前时间得到学年学期工具类

public static String getCurrentTerm() {
        // 获取当前时间
        LocalDateTime now = LocalDateTime.now();

        // 确定当前学年学期的起始和结束时间
        int year = now.getYear();
        LocalDateTime autumnStart = LocalDateTime.of(year, 9, 1, 0, 0);
        LocalDateTime springStart = LocalDateTime.of(year, 2, 1, 0, 0);

        // 计算当前学年学期
        if (now.isBefore(springStart)) {
            return (year - 1) + "-" + year + "-1";
        } else if (now.isAfter(autumnStart)) {
            return year + "-" + (year + 1) + "-1";
        } else {
            return (year - 1) + "-" + year + "-2";
        }
    }
