SpringBoot-邮件任务

邮件发送，在我们的日常开发中，也非常的多，Springboot也帮我们做了支持

邮件发送需要引入spring-boot-start-mail
SpringBoot 自动配置MailSenderAutoConfiguration
定义MailProperties内容，配置在application.yml中
自动装配JavaMailSender
测试邮件发送

1、引入pom依赖

<dependency>

   <groupId>org.springframework.boot</groupId>

   <artifactId>spring-boot-starter-mail</artifactId>

</dependency>

2、查看自动配置类：MailSenderAutoConfiguration

@Configuration(

    proxyBeanMethods = false

)

@ConditionalOnClass({MimeMessage.class, MimeType.class, MailSender.class})

@ConditionalOnMissingBean({MailSender.class})

@Conditional({MailSenderAutoConfiguration.MailSenderCondition.class})

@EnableConfigurationProperties({MailProperties.class})

@Import({MailSenderJndiConfiguration.class, MailSenderPropertiesConfiguration.class})

public class MailSenderAutoConfiguration {

    public MailSenderAutoConfiguration() {

    }

    static class MailSenderCondition extends AnyNestedCondition {

        MailSenderCondition() {

            super(ConfigurationPhase.PARSE_CONFIGURATION);

        }

        @ConditionalOnProperty(

            prefix = "spring.mail",

            name = {"jndi-name"}

        )

        static class JndiNameProperty {

            JndiNameProperty() {

            }

        }

        @ConditionalOnProperty(

            prefix = "spring.mail",

            name = {"host"}

        )

        static class HostProperty {

            HostProperty() {

            }

        }

    }

}

然后我们去看下配置文件MailProperties

public class MailProperties {

    private static final Charset DEFAULT_CHARSET;

    private String host;

    private Integer port;

    private String username;

    private String password;

    private String protocol = "smtp";

    private Charset defaultEncoding;

    private Map<String, String> properties;

    private String jndiName;

    .....

}

MailProperties 中就是我们能自己去定义的属性。

3、配置文件：

spring.mail.username=1763204261@qq.com

spring.mail.password=qq邮箱授权码

spring.mail.host=smtp.qq.com

# qq需要配置ssl

spring.mail.properties.mail.smtp.ssl.enable=true

获取授权码：在QQ邮箱中的设置->账户->开启pop3和smtp服务

4、Spring单元测试

    @Autowired

    JavaMailSenderImpl mailSender;

    @Test

    public void emailTest(){

        //邮件设置1：一个简单的邮件

        SimpleMailMessage message = new SimpleMailMessage();

        message.setSubject("通知-你收到邮件了");

        message.setText("神圣的时刻来了！");

        message.setTo("1763204261@qq.com");

        message.setFrom("1763204261@qq.com");

        mailSender.send(message);

    }

查看邮箱，邮件接收成功！

上面这个是比较简单的邮件发送，有时候会需要更复杂的，比如带入文件之类的：

此时需要用 MimeMessage

　　@Autowired

    JavaMailSenderImpl mailSender;

    @Test

    public void contextLoads2() throws MessagingException {

        //邮件设置2：一个复杂的邮件

        MimeMessage mimeMessage = mailSender.createMimeMessage();

        MimeMessageHelper helper = new MimeMessageHelper(mimeMessage, true);

        helper.setSubject("通知-收到文件邮件");

        helper.setText("<b style='color:red'>又是神圣的时刻！</b>",true);

        //发送附件

        helper.addAttachment("1.jpg",new File("G:\\1.jpg"));

        helper.setTo("1763204261@qq.com");

        helper.setFrom("1763204261@qq.com");

        mailSender.send(mimeMessage);

    }

测试

和预想的一样！
