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、找到符合主题的邮件，如包含（58.com）……，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

网上普遍可寻找到遵循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.com");    // pop3服务器  // SSL安全连接参数props.setProperty("mail.pop3.socketFactory.class", "javax.net.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 = Session.getInstance(props);  Store store = session.getStore("pop3");  store.connect("pop.qq.com","2627178143@qq.com", "......");//前面是我的邮箱号，后面填入自己的登陆码即可// 获得收件箱  Folder folder = store.getFolder("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: " + folder.getMessageCount());  // 得到收件箱中的所有邮件,并解析  try{Message[] messages = folder.getMessages();  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.com，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("未找到要解析的邮件!");  //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 = Pattern.compile("<h3.*?>([\\s\\S]*)<span.*?>([\\s\\S]*)</span></h3>");Pattern p2 = Pattern.compile("<label.*?>([\\s\\S]*)<span.*?><span.*?>([\\s\\S]*)</span></span></label>");Pattern p3 = Pattern.compile("<ul.*?>[\\s]*?<li.*?>([^\n]*)</li>[\\s]*?<li.*?>([^\n]*)</li>[\\s]*?<li.*?>([^\n]*)</li>[\\s]*?<li.*?>([^\n]*)</li>[\\s]*?</ul>");Pattern p4 = Pattern.compile("<label.*?>([\\s\\S]*)<span.*?>([\\s\\S]*)</span></label>");//斗米简历整理工具，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//???Date now = new Date();

主函数的调用

前面的异常处理里都添加了输出语句，可要可不要，另外对于程序中提示要添加的类，一定要看仔细了，经常会出现jar包名字不一样却有相同名字的类，添加错了，程序就出了问题，之前浪费了我不少的时间找bug。。。以下是我的程序里需要添加的类及主函数：

import java.io.BufferedInputStream;
import java.io.BufferedOutputStream;
import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.UnsupportedEncodingException;
import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Date;
import java.util.Properties;  import java.util.regex.Matcher;
import java.util.regex.Pattern;import javax.mail.Address;
import javax.mail.BodyPart;
import javax.mail.Flags;
import javax.mail.Folder;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.Multipart;
import javax.mail.Part;
import javax.mail.Session;
import javax.mail.Store;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeMultipart;
import javax.mail.internet.MimeUtility;  import jxl.Workbook;
import jxl.write.Label;
import jxl.write.WritableSheet;
import jxl.write.WritableWorkbook;
import jxl.write.WriteException;
import jxl.write.biff.RowsExceededException;public static void main(String[] args) throws Exception {  try{receive();}catch(Exception e){e.printStackTrace();System.out.println("receive异常");}  }

这个Java程序的名字自己随机取得，只是一个外壳，对内部程序没有影响。
有什么问题希望大家可以留言一起交流哈，集思广益，加油加油在加油，勤能补拙，希望自己技能日以渐进！
