Java

当我们在outlook中保存一个邮件是可以存成eml格式，这种格式是标准的邮件格式. 这种文件可以用JavaMail来解析。

import java.util.*;

import java.io.*;

import javax.mail.*;

import javax.mail.internet.*;

public class ReadEmail {

public static void main(String args[]) throws Exception{

display(new File("C:\\temp\\message.eml"));

}

public static void display(File emlFile) throws Exception{

Properties props = System.getProperties();

props.put("mail.host", "smtp.dummydomain.com");

props.put("mail.transport.protocol", "smtp");

Session mailSession = Session.getDefaultInstance(props, null);

InputStream source = new FileInputStream(emlFile);

MimeMessage message = new MimeMessage(mailSession, source);

System.out.println("Subject : " + message.getSubject());

System.out.println("From : " + message.getFrom()[0]);

System.out.println("--------------");

System.out.println("Body : " + message.getContent());

}

}

eml文件格式说明 :
