Java发送简单邮箱

话不多说，直接上代码带注释，首先需要引入一个jar包（我是这个版本）：javax.mail-1.6.2.jar.，

package java_mail;
    
    import java.util.Date;
    import java.util.Properties;
    
    import javax.mail.Address;
    import javax.mail.Session;
    import javax.mail.Transport;
    import javax.mail.internet.InternetAddress;
    import javax.mail.internet.MimeMessage;
    /**javaMail*/
    public class JavaMailDemo { 
    	public static void main(String[] args) throws Exception{ 
    		Properties props= new Properties();
    		props.setProperty("mail.transport.protocol", "smtp");	//使用smtp协议
    		props.setProperty("mail.smtp.host", "smtp.qq.com");		//qq邮箱协议地址
    		props.setProperty("mail.smtp.port", "465");				//qq邮箱协议端口号
    		props.setProperty("mail.smtp.auth", "true");			//授权
    		
    		//QQ邮箱：SSL安全认证(使用类javax.net.ssl.SSLSocketFactory支持)
    		props.setProperty("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
    		//是否处理非 SSL认证的请求
    		props.setProperty("mail.smtp.socketFactory.fallback", "false");
    		//SSL端口号(与QQ邮箱端口一致)
    		props.setProperty("mail.smtp.socketFactory.port", "465");
    		
    		
    		Session session = Session.getInstance(props);
    		session.setDebug(true); //开启日志
    		//创建邮件
    		MimeMessage message = createMimeMessage(session,"发送人邮箱","收件人邮箱");
    		//建立连接对象
    		Transport transport = session.getTransport();
    		//建立连接 qq,授权码
    		transport.connect("发送人邮箱","这里填第三方授权码");
    		//发送
    		transport.sendMessage(message, message.getAllRecipients());
    		//发送完毕后关闭连接
    		transport.close();
    	}
    	
    	
    	/** * @param session * @param send 发送人 * @param recive 收件人 * @param cRecive 抄送人 * @param mRecive 密送人 * @return 邮件对象 * @throws Exception */
    	//,String cRecive,String mRecive 我这里不要抄送密送了
    	public static MimeMessage createMimeMessage(Session session,String send,String recive) throws Exception{ 
    		MimeMessage message = new MimeMessage(session);
    		//添加发件人
    		Address address = new InternetAddress(send,"发件人的name","UTF-8");
    		message.setFrom(address);
    		//设置邮箱标题，编码格式
    		message.setSubject("这是java邮件的标题", "UTF-8");
    		//设置正文
    		message.setContent("正文内容", "text/html; charset=utf-8");
    		//设置收件人类型： .TO普通收件人、CC抄送、BCC密送
    		message.setRecipient(MimeMessage.RecipientType.TO, new InternetAddress(recive,"收件人A","UTF-8"));
    // message.setRecipient(MimeMessage.RecipientType.CC, new InternetAddress(cRecive,"抄送人B","UTF-8"));
    // message.setRecipient(MimeMessage.RecipientType.BCC, new InternetAddress(mRecive,"密送人C","UTF-8"));
    		
    		//设置发件日期
    		message.setSentDate(new Date());
    		message.saveChanges();
    		return message;
    	}
    	
    }

获取三方邮箱登录授权码，以QQ邮箱为例：
