问题：
在一次客户要求更换邮件发送方式的时候。需要使用outlook邮箱，端口是587.所以需要对原有的发邮件代码做一些修改
解决办法：
我直接把工具类贴出来，我只在类中加了两行代码：
props.put("mail.smtp.starttls.enable", "true");props.put("mail.smtp.port", "587");工具类如下：
import java.io.File;
import java.io.FileInputStream;
import java.io.UnsupportedEncodingException;
import java.util.ArrayList;
import java.util.List;
import java.util.Map;
import java.util.Properties;
import java.util.Set;
import javax.activation.CommandMap;
import javax.activation.DataHandler;
import javax.activation.FileDataSource;
import javax.activation.MailcapCommandMap;
import javax.mail.*;
import javax.mail.internet.*;
import com.datadriver.common.util.log.Logger;
import com.datadriver.sequoia.util.Switch;
