项目中用到Spring Boot发QQ邮箱给女朋友

spring.mail.host=smtp.qq.com
spring.mail.protocol=smtp
spring.mail.username=1974627037@qq.com
spring.mail.default-encoding=UTF-8
spring.mail.port=465
spring.mail.properties.mail.smtp.socketFactory.class=javax.net.ssl.SSLSocketFactory
spring.mail.properties.mail.debug=true
spring.mail.password=hpqxqvacriwibdbe

7.单元测试

@RunWith(SpringRunner.class)
@SpringBootTest
public class MailApplicationTests {
    @Autowired
    JavaMailSender mailSender;
    @Test
    public void contextLoads() {
        SimpleMailMessage msg = new SimpleMailMessage();
        msg.setTo("2579605371@qq.com");
        msg.setCc("757919476@qq.com");
        msg.setSubject("这是一封测试情书");
        msg.setFrom("1974627037@qq.com");
        msg.setSentDate(new Date());
        msg.setText("哈哈！你行不行啊");
        mailSender.send(msg);
    }
复制代码

8.用网页格式发送需要导pom.xml依赖

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-thymeleaf</artifactId>
        </dependency>
复制代码

9.写个main.html页

<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
    <p>欢迎<span style="color: #ffff11;" th:text="${username}"></span> 加入
    XXX 大家庭</p>
    <div>你的入职信息如下：</div>
<table torder="1">
    <tr>
        <td>职位</td>
        <td>th:text="${position}"</td>

    </tr>
    <tr>
        <td>薪资</td>
        <td th:text="${salary}"></td>

    </tr>
</table>
</body>
</html>
