一、普通邮件发送

编写配置信息【app.xml】

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context https://www.springframework.org/schema/context/spring-context.xsd">

    <context:component-scan base-package="cn.zeal4j"/>

    <bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
        <property name="host" value="smtp.qq.com" />
        <property name="port" value="587" />
        <property name="username" value="zeal4j" />
        <property name="password" value="frcgbdjqjzptbegg" />
        <property name="defaultEncoding" value="utf-8"/>
    </bean>

    <bean id="mailMessage" class="org.springframework.mail.SimpleMailMessage">
        <property name="from" value="zeal4j@qq.com" />
        <property name="subject" value="spring-mail"/>
    </bean>
</beans>

管理器类：

package cn.zeal4j.util.springmail;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.mail.MailMessage;
import org.springframework.mail.MailSender;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.stereotype.Component;

/**
 * @author Administrator
 * @file IntelliJ IDEA Spring-Mail
 * @create 2020 09 22 12:38
 */
@Component
public class MailOrderManager implements OrderManager{

    @Autowired
    private MailSender mailSender;
    @Autowired
    private MailMessage mailMessage;

    public void placeOrder() {
        mailMessage.setTo("zeal4j@qq.com");
        mailMessage.setText("This message powered by Spring-Mail, 测试");
        mailSender.send((SimpleMailMessage) mailMessage);
    }
}

接口：

package cn.zeal4j.util.springmail;

/**
 * @author Administrator
 * @file IntelliJ IDEA Spring-Mail
 * @create 2020 09 22 12:39
 */
public interface OrderManager {

    void placeOrder();
}

测试：

    @Test
    public void sendSpringMail() {
        ApplicationContext applicationContext = new ClassPathXmlApplicationContext("app.xml");
        MailOrderManager mailOrderManager = applicationContext.getBean("mailOrderManager", MailOrderManager.class);
        mailOrderManager.placeOrder();
    }

二、带附件邮件发送：

    @Test
    public void sendSpringMailWithAttachment() throws Exception{
        ApplicationContext applicationContext = new ClassPathXmlApplicationContext("app.xml");

        JavaMailSender mailSender = applicationContext.getBean("mailSender", JavaMailSender.class);

        MimeMessage mimeMessage = mailSender.createMimeMessage();

        mimeMessage.setSubject("Spring-Mail 附件测试");

        MimeMessageHelper mimeMessageHelper = new MimeMessageHelper(mimeMessage, true, "utf-8");

        mimeMessageHelper.setTo("zeal4j@qq.com");

        mimeMessageHelper.setFrom("zeal4j@qq.com");

        mimeMessageHelper.setText("Spring-Mail 附件测试 ......");

        File file = new File("D:\\picture\\collection\\bg.jpg");

        mimeMessageHelper.addAttachment(file.getName(), file);

        mailSender.send(mimeMessage);
    }
