Java登录QQ邮箱整理邮件的58的简历（⼀）
Java登录QQ邮箱整理邮件的58的简历
实习期间给公司做的第⼀个⼩⼯具，只需下载jxl.jar和mail.jar的第三⽅那个类库，就可以着⼿敲代码了：
1、此次是使⽤POP3协议登录的邮箱，使⽤了⼿机获取的账号配置码
2、遍历收件箱的所有邮件，判断邮件类型，得到邮件的内容
3、解析每⼀封邮件的内容，parseMessage(Message …messages)
4、到符合主题的邮件，如包含（58）……，getSubject(MimeMessage msg)
5、针对特定邮件解析出相应内容，并创建excel表，⼀条条的存⼊其中
6、所有简历的部分信息先放在Excel表中集合，关闭表
登录邮箱
⽹上普遍可寻到遵循POP3协议及IMAP协议的登录⽅式，下⾯我⽤的是POP3协议，缺陷是不能给邮件做标记，只能读，不可改变邮件的状态及属性，后⾯会有IMAP协议的登录的⽅式的博客进⾏补充…….
另外敲代码前，先去邮箱的设置⾥，进去“账户”的设置，开启POP3协议的开启功能，使⽤⼿机发送信息得到登录码，很⽅便，可避免修改了密码，或是邮箱设置了独⽴密码等层层关卡的⿇烦。写成了⽅法，代码如下
public static void receive() throws Exception {
// 准备连接服务器的会话信息
Properties props = new Properties();
//props.setProperty("mail.store.protocol", "pop3"); // 协议
props.setProperty("mail.pop3.port", "110"); // 端⼝
props.setProperty("mail.pop3.host", "pop.qq"); // pop3服务器
// SSL安全连接参数
props.setProperty("mail.pop3.socketFactory.class", "javax.ssl.SSLSocketFactory");
props.setProperty("mail.pop3.socketFactory.fallback", "true");
props.setProperty("mail.pop3.socketFactory.port", "995");
// 创建Session实例对象
Session session = Instance(props);
Store store = Store("pop3");
// 获得收件箱
Folder folder = Folder("INBOX");
/* Folder.READ_ONLY：只读权限
* Folder.READ_WRITE：可读可写（可以修改邮件的状态）
*/
folder.open(Folder.READ_WRITE); //打开收件箱
// 由于POP3协议⽆法获知邮件的状态，所以getUnreadMessageCount得到的是收件箱的邮件总数
// 获得收件箱中的邮件总数
System.out.println("邮件总数: " + MessageCount());
// 得到收件箱中的所有邮件，并解析
try{
Message[] messages = Messages();
parseMessage(messages);
//释放资源
folder.close(true);
store.close();
}catch(Exception e){
e.printStackTrace();
System.out.println("receive内部异常");}
}
解析邮件
判断主题⾥是否有58，并判断该邮件是否是当天的，整理当天的邮件信息存⼊Excel表中去：
public static void parseMessage(Message ...messages) throws MessagingException, IOException {
if (messages == null || messages.length < 1)
throw new MessagingException("未到要解析的邮件!");
//58简历整理⼯具，使⽤正则表达式匹配相应的信息：姓名，性别，年龄，电话，邮箱，经验
Pattern p1 = Patternpile("<h3.*?>([\\s\\S]*)<span.*?>([\\s\\S]*)</span></h3>");
Pattern p2 = Patternpile("<label.*?>([\\s\\S]*)<span.*?><span.*?>([\\s\\S]*)</span></span></label>");
Pattern p3 = Patternpile("<ul.*?>[\\s]*?<li.*?>([^\n]*)</li>[\\s]*?<li.*?>([^\n]*)</li>[\\s]*?<li.*?>([^\n]*)</li>[\\s]*?<li.*?>([^\n]*)</li>[\\s]*?</ul>");
Pattern p4 = Patternpile("<label.*?>([\\s\\S]*)<span.*?>([\\s\\S]*)</span></label>");
