Spring boot邮件使用（一）

完整代码

一、邮件发送之文本邮件

即最简单的邮件发送，只有标题和文本内容，就当入门。
首先引入依赖，然后在配置文件中配置，最后测试就可以了。
pom引入依赖：

		
        
            org.springframework.boot
            spring-boot-starter-mail
        

配置文件，application.properties

###  配置邮件参数
#邮件协议
spring.mail.host=smtp.qq.com

[email protected]
#这里是客户端授权码，不是客户端登陆密码
spring.mail.password=xxxxxxxxxxxxx
#编码格式
spring.mail.default-encoding=UTF-8

写邮件发送的方法：

@Service
public class FirstEmailService {

    @Value("${spring.mail.username}")  //在项目启动时将配置文件中的信息注入到这里
    private String from;

    @Autowired
    private JavaMailSender javaMailSender;  //用来发送邮件

    //发送简单邮件
    public void sendSimpleMail(String to,String title,String content){
        SimpleMailMessage simpleMailMessage = new SimpleMailMessage();
        simpleMailMessage.setTo(to);
        simpleMailMessage.setSubject(title);
        simpleMailMessage.setText(content);
        simpleMailMessage.setFrom(from);

        javaMailSender.send(simpleMailMessage);
    }
}

开始测试，以及运行后的结果：

 @Test
    public void testFirstEmail() {
        emailService.sendSimpleMail("[email protected]","test--first email","测试邮件发送----第一封");
    }

二、邮件发送之html邮件

只需要添加方法即可：

//发送html邮件
    public void sendHtmlMail(String to,String title,String content) throws MessagingException {
        MimeMessage mimeMessage = javaMailSender.createMimeMessage();
        MimeMessageHelper helper = new MimeMessageHelper(mimeMessage,true);
        helper.setTo(to);
        helper.setSubject(title);
        helper.setText(content,true);
        helper.setFrom(from);

        javaMailSender.send(mimeMessage);
    }

然后测试：

    @Test
    public void testSecondEmail() throws MessagingException {
        String content = "\n\n" +
                "\n " +
                "
测试邮件发送----第二封
\n" +
                "\n" +
                "\n" +
                "" +
                "\n" +
                "\n" +
                "" +
                "\n" +
                "
1
2
lj
test
\n" +
                "\n" +
                "\n";
        emailService.sendHtmlMail("[email protected]", "test--second email", content);
    }

三、邮件发送之附件邮件

添加发送附件的方法

//发送附件邮件
    public void sendAttachmentsMail(String to,String title,String content,String filepath) throws MessagingException {
        MimeMessage mimeMessage = javaMailSender.createMimeMessage();
        MimeMessageHelper helper = new MimeMessageHelper(mimeMessage,true);
        helper.setTo(to);
        helper.setSubject(title);
        helper.setText(content,true);

        FileSystemResource fileSystemResource = new FileSystemResource(new File(filepath));
        String filename = fileSystemResource.getFilename();//获得文件名称
        helper.addAttachment(filename,fileSystemResource);
//   helper.addAttachment(filename+“test”,fileSystemResource);  发送多个附件内容

        helper.setFrom(from);

        javaMailSender.send(mimeMessage);
    }

测试

  @Test
    public void testThirdEmail() throws MessagingException {
        String content = "\n\n" +
                "\n " +
                "
测试邮件发送----第二封
\n" +
                "\n" +
                "\n" +
                "" +
                "\n" +
                "\n" +
                "" +
                "\n" +
                "

2
lj
test
\n" +
                "\n" +
                "\n";
        emailService.sendHtmlMail("[email protected]", "test--second email", content);
    }

四、邮件发送之图片邮件

添加方法：

   //发送图片邮件
    public void sendPictureMail(String to,String title,String content,String rscPath,String rscId) throws MessagingException {
        MimeMessage mimeMessage = javaMailSender.createMimeMessage();
        MimeMessageHelper helper = new MimeMessageHelper(mimeMessage,true);
        helper.setTo(to);
        helper.setSubject(title);
        helper.setText(content,true);

        FileSystemResource rsc = new FileSystemResource(new File(rscPath));
        helper.addInline(rscId,rsc);

        helper.setFrom(from);

        javaMailSender.send(mimeMessage);
    }

测试：

@Test
    public void testForthEmail() throws MessagingException {
        String rscId = "picture001";
        String content = "\n\n" +
                "\n " +
                "
测试邮件发送----第四封
\n" +
                "
\n" +
                "发送图片邮件\n" +
                "\n"+
                "
\n" +
                "\n" +
                "\n";
        emailService.sendPictureMail("[email protected]", "test--forth email", content,"C:\\Users\\lj\\Desktop\\22.jpg",rscId);
    }

在这里插入图片描述

GOOD LUCK！！！
