寫手機驗證碼時間驗證方法

<select id="getNumber"  resultType="java.lang.Integer">
    select  count(*)  from telephonecode where
    create_time>=#{starttime} and create_time&lt;=#{endtime} and telephone=#{telephone}
</select>

 

這個是映射xml裏最有效果一條

 

public static Date yesterday(){
    //獲取當前時間24小時前的時間
    Calendar c = Calendar.getInstance();
    c.setTime(new Date());
    c.set(Calendar.HOUR_OF_DAY,c.get(Calendar.HOUR_OF_DAY) - 24);
    Date time= c.getTime();
    return time;
}
public static Date onehour(){
    //獲取當前時間1小時前的時間
    Calendar c = Calendar.getInstance();
    c.setTime(new Date());
    c.set(Calendar.HOUR_OF_DAY,c.get(Calendar.HOUR_OF_DAY) - 1);
    Date time= c.getTime();
    return time;
}
public static Date oneminute(){

    return  new Date(System.currentTimeMillis()-1000*60);

}
