首先定义一个生日属性的实体对象：
@Getter @Setter public class BirthInfo { // 阳历 // 日期 private String solarDay; // 时间，精确到分即可 private String time; // 星期 private String weekday; // 星座 private String constellation; // 阴历 // 阴历年 private String lunarYear; // 阴历月日 private String lunarDay; // 生辰 private String period; // 属相 private String zodiac; // 八字 private String bazi; // 五行 private String wuxing; private String wuxingDesc; @Override public String toString() { return solarDay + " " + time + "\n" + weekday + "\n" + constellation + "\n\n" + lunarYear + lunarDay + "\n" + period + "\n" + zodiac + "\n" + bazi + "\n" + wuxing + "\n" + wuxingDesc; } }
传入日期格式“1999-12-12 12:12”，调用guess得出计算结果：
