javamail开发简例

1)引入全部mailjar包 包括activation.jar 和mail.jar

2)实例一:

package testMail;   
  
import java.util.Date;    
import java.util.Properties;    
  
import javax.mail.Address;    
import javax.mail.Message;    
import javax.mail.Session;    
import javax.mail.Transport;    
import javax.mail.internet.InternetAddress;    
import javax.mail.internet.MimeMessage;
