没有看考勤的习惯，导致我的一天班白上了，都是钱啊，系统也不发个邮件通知下。。。。
为了避免以后还有类似状况特别写了个java模拟登录抓取考勤内容的方法(部分代码来自网络)，希望有人修改后也可以用上，哈哈！
公司内部系统，登录没有验证码，如果是有验证码的系统还得找破解方法
定时器是用的spring的，没用spring的可以自己写个定时器
用到的组件：httpclient-4.2.5.jar,httpcore-4.2.4.jar,jsoup-1.7.2.jar
jsoup官方下载地址：http://jsoup.org/download
httpclient官方下载地址:http://hc.apache.org/downloads.cgi
废话不多说，贴上我的代码
@Component
public class Login extends BaseJobs { SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
/**
* 获取当月第一天
*
* @return
*/
public String getFirstDayOfMonth() {
Calendar lastDate = Calendar.getInstance();
lastDate.set(Calendar.DATE, 1);// 设为当前月的1号
return sdf.format(lastDate.getTime()); } /**
* 计算当月最后一天
* @return
*/
public String getLastDayOfMonth() { Calendar lastDate = Calendar.getInstance();
lastDate.set(Calendar.DATE, 1);// 设为当前月的1号
lastDate.add(Calendar.MONTH, 1);// 加一个月，变为下月的1号
lastDate.add(Calendar.DATE, -1);// 减去一天，变为当月最后一天
return sdf.format(lastDate.getTime()); } //测试
public static void main(String args[]) throws Exception {
Login l = new Login();
l.login();
} private static CookieStore cs = new BasicCookieStore(); //利用spring定时器 每天早上10点一刻抓取并发邮件
