发邮件-java

发送邮件的邮箱设置

• 开启客户端授权码，如图：
  • 

代码部分

• 导入依赖项如下：

		<!-- 发送邮件 -->
		<dependency>
			<groupId>com.sun.mail</groupId>
			<artifactId>javax.mail</artifactId>
			<version>1.5.3</version>
		</dependency>
		<dependency>
			<groupId>javax.mail</groupId>
			<artifactId>javax.mail-api</artifactId>
			<version>1.5.6</version>
		</dependency>

• 封装一个写邮件的类，并定义一个含有两个参数的发邮件的静态方法，

• 传过来发送到的邮箱地址，与想要发送的内容，这里发送的是一个激活链接

• 在类的title写邮件的标题，body中写要发送的内容，也可以设置成参数传过来

• 代码如下：

public class WriteEmail {

	public static void emailSend(String email,String url) {
		
		// http://blog.youkuaiyun.com/ja_ii_ck/article/details/3018553
		
		String smtpHost = "smtp.126.com";
		
		String toaddress = email;
		String user = "********@126.com";
		String password = "*********";
		

		String title = "公开课验证!";
		String body = "点击此链接激活:"+url;
		
		Properties props = new Properties();
		props.put("mail.smtp.host", smtpHost);
		props.put("mail.smtp.auth", "true");
		Session session = Session.getDefaultInstance(props, new Authenticator() {
			public PasswordAuthentication getPasswordAuthentication() {
				return new PasswordAuthentication(user, password);
			}
		});

		MimeMessage message = new MimeMessage(session);
		try {
			message.setSubject(title);
			message.setText(body);
			message.setFrom(new InternetAddress("******@126.com"));
			message.addRecipient(Message.RecipientType.TO, new InternetAddress(toaddress));

			Transport.send(message);
			System.out.println("发送成功");
		} catch (MessagingException e) {
			System.out.println(e);
		}
	}
}

控制层，只需要调用静态类中的方发即可发送邮件，如下：

 WriteEmail.emailSend(user.getEmail(), "http://localhost:8088/" + salt);
