农历和阳历的之间的转换

1.首先拷贝这两个实体类

@Data
public class Lunar {private boolean isleap;private int lunarDay;private int lunarMonth;private int lunarYear;
}

@Data
public class Solar {private int solarDay;private int solarMonth;private int solarYear;
}

2.然后考入下面的类

/*** 农历和阳历的互相转换* @author hj* @date 2020/9/11*/
