Java中有mail的技术。使用Spring的mail可以简化代码

上Spring mail API的demo代码，代码上的注释足以说明一切，实际上这是一个十分简单的技术。。。。

package org.mail.test;
    
    import java.io.File;
    import java.util.Properties;
    
    import javax.mail.internet.MimeMessage;
    
    import org.springframework.core.io.FileSystemResource;
    import org.springframework.mail.javamail.JavaMailSenderImpl;
    import org.springframework.mail.javamail.MimeMessageHelper;
    
    public class SpringMail
    {
    	
    	private static String host = "smtp.qq.com";
    
    	//目的邮箱  写上自己要发送的邮箱地址
    	private static String to = "";
    
    	//发送邮箱  写上自己要发送的邮箱地址....
    	private static String from = "";
    
    	//用户名
    	private static String username = "";
    
    	//密码
    	private static String password = "";
    
    	//邮件主题
    	private static String subject = "测试邮件主题...";
    	
    	
    	private static Properties prop = new Properties();
    
    	static
    	{
    		prop.put(" mail.smtp.auth ", "false"); 
    		prop.put(" mail.smtp.timeout ", " 25000 ");
    		prop.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
    		prop.put("mail.smtp.port", 465);
    	}
    	
    
    	public static void main(String[] args) throws Exception
    	{
    		JavaMailSenderImpl javaMailSenderImpl = new JavaMailSenderImpl();
    		
    		MimeMessage mimeMessage = javaMailSenderImpl.createMimeMessage();
    		
    		javaMailSenderImpl.setHost(host);
    		javaMailSenderImpl.setUsername(username);
    		javaMailSenderImpl.setPassword(password);
    
    		
    		MimeMessageHelper mimeMessageHelper = new MimeMessageHelper(mimeMessage,true,"utf-8");
    		
    		mimeMessageHelper.setFrom(from);
    		mimeMessageHelper.setSubject(subject);
    		mimeMessageHelper.setText("",true);
    		mimeMessageHelper.setTo(to);
    		mimeMessageHelper.addAttachment("hello.jpg",new FileSystemResource(new File("C:/Users/Administrator/Desktop/icon.JPG")));
    		
    		javaMailSenderImpl.setJavaMailProperties(prop);
    		
    		javaMailSenderImpl.send(mimeMessage);
    		System.out.println("send message ok .....");
    	
    	}
    }
