javamail

1.spring.xml配置

2.Controller层

3.Service接口

4.接口的实现类

因为要邮件要带附件，所以SimpleMailMessage不能用，要换成的MimeMessage

参考的演示

1) 引入jar包

2) spring配置文件中初始化mail sender
<bean name="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
      <property name="host">
          <value>smtp.sina.com</value>
      </property>
      <property name="javaMailProperties">
          <props>
            <prop key="mail.smtp.auth">true</prop>
            <prop key="mail.smtp.starttls.enable">true</prop>
            <prop key="mail.smtp.starttls.required">true</prop>
          </props>
      </property>
      <property name="username">
          <value>XXX@sina.com</value>
      </property>
      <property name="password">
          <value>XXX</value>
      </property>
</bean>

3)  代码使用
 
    @Component
    public class XXX 

	@Autowired
	protected JavaMailSender sender;
	
       //发送邮件
	@Override
	public void sendMail(SimpleMailMessage message) throws Exception {
		sender.send(message);
	}
	
        //构建邮件对象
	@Override
	public SimpleMailMessage buildSimpleMessage(AlarmData alarmData, AlarmForward forward) {
		logger.info("buildSimpleMessage, forwardrule={}", forward);
		SimpleMailMessage message = new SimpleMailMessage();
		message.setFrom(from);
		message.setTo(forward.getEmailaddr().split(","));
		message.setSubject(forward.getTitle());
		message.setText("设备:" + alarmData.getDeveui() + " 上报告警，请及时处理！");
		return message;
	}

补充：

本机测试的环境不是阿里云环境，没有设置端口号（好像默认的端口号为25），测试可以发送邮件，

但阿里云环境要有端口号，加上端口号587

<property name="port">

     <value>587</value>

</property>

<bean name="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
      <property name="host">
          <value>smtp.sina.com</value>
      </property>
      <property name="port">
          <value>587</value>
      </property>
      <property name="javaMailProperties">
          <props>
            <prop key="mail.smtp.auth">true</prop>
            <prop key="mail.smtp.starttls.enable">true</prop>
            <prop key="mail.smtp.starttls.required">true</prop>
          </props>
      </property>
      <property name="username">
          <value>XXX@sina.com</value>
      </property>
      <property name="password">
          <value>XXX</value>
      </property>
</bean>
