Springboot实现邮件发送

　　本文以QQ邮箱为例，实现springboot邮件发送

邮箱设置主要获取授权码
按照步骤开启服务获取授权码

导入依赖

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-mail</artifactId>
 </dependency>

配置邮件发送类

@Configuration
public class TestConfig {

    @Bean
    public JavaMailSender javaMailSender() {
        JavaMailSenderImpl javaMailSender = new JavaMailSenderImpl();
        javaMailSender.setPassword(授权码);
        javaMailSender.setHost("smtp.qq.com");
        javaMailSender.setUsername(邮箱名称);
        javaMailSender.setPort(587);
        return javaMailSender;
    }
}

邮箱地址，端口参数在qq邮箱帮助中心搜索SSL获取，如下：

测试发送

@Autowired
    private JavaMailSender javaMailSender;

    @Test
    public void testSendMail() {
        SimpleMailMessage simpleMailMessage = new SimpleMailMessage();
        simpleMailMessage.setFrom("xxx@qq.com");
        simpleMailMessage.setTo("xxx@qq.com");
        simpleMailMessage.setSentDate(new Date());
        simpleMailMessage.setSubject("测试");
        simpleMailMessage.setText("简单邮件可以直接构建一个SimpleMailMessage对象进行配置，配置完成后，通过JavaMailSender将邮件发送出去");
        javaMailSender.send(simpleMailMessage);
    }
