```java
/**
* 获取某月的最后一天
*/
@Override
public Date getLastDayOfMonth(int year, int month) {
Calendar cal = Calendar.getInstance();
//设置年份
cal.set(Calendar.YEAR, year);
//设置月份
cal.set(Calendar.MONTH, month );
cal.set(Calendar.DAY_OF_MONTH, 0);
cal.set(Calendar.HOUR_OF_DAY, cal.getActualMaximum(Calendar.HOUR_OF_DAY));
cal.set(Calendar.MINUTE, cal.getActualMaximum(Calendar.MINUTE));
cal.set(Calendar.SECOND, cal.getActualMaximum(Calendar.SECOND));
cal.set(Calendar.MILLISECOND, cal.getActualMaximum(Calendar.MILLISECOND));
Date date = cal.getTime();
return date;
