问题描述

我一直在尝试通过 spring boot 发送电子邮件，但似乎无法成功.我已经使用javamail api很长时间了，但想在spring mail中使用springboot.

公共类 SendMail {@自动连线私人 JavaMailSender javaMailSender;公共无效发送邮件(字符串到，字符串主题，字符串正文){SimpleMailMessage message = new SimpleMailMessage();message.setTo(to);message.setSubject(主题);message.setText(body);javaMailSender.send(message);}}

这是我的邮件

@Controller公共类示例{@自动连线私人 SendMail sendMail;@RequestMapping("/他")公共字符串主页(){sendMail.sendingMail("bobobush007@gmail.com", "欢迎乔治", "示例消息");返回已发送"；}}

我的 pom 文件中已经有 sprint-boot-starter-mail，但我不断收到此错误消息.我什至看过有关如何执行此操作的教程的 youtube 视频，但它不起作用.我使用的是 Spring Tool Suite 版本:3.9.0.RELEASE.

属性文件

spring.mail.host=smtp.gmail.comspring.mail.username=我的电子邮件地址spring.mail.password=我的密码spring.mail.port=587spring.mail.properties.mail.smtp.auth=truespring.mail.properties.mail.smtp.starttls.enable=truespring.mail.defaultEncoding=UTF-8

说明:

com.example.demo.Example 中的字段 sendMail 需要一个 bean 类型找不到com.example.demo.SendMail".

操作:

考虑定义一个类型为 'com.example.demo.SendMail' 的 bean配置.

这是我的 Pom 文件

我已经卸载了 jdk 和 STS 并安装了新副本.现在出现此错误

解决方案

这有效.

@Service公共类 SendMail {@自动连线私人 JavaMailSender javaMailSender;公共无效发送邮件(字符串到，字符串主题，字符串正文){MimeMessage 消息=javaMailSender.createMimeMessage();MimeMessageHelper 助手；helper=new MimeMessageHelper(message,true);helper.setTo(to);helper.setSubject(主题);helper.setText(body);javaMailSender.send(message);}}

I have been trying to send email via spring boot and i cant seem to succeed. I am been using javamail api for a long time now but want to use springboot with spring mail.

public class SendMail {

    @Autowired
    private JavaMailSender javaMailSender;

    public void sendingMail(String to, String subject, String body) {
        SimpleMailMessage message = new SimpleMailMessage();
        message.setTo(to);
        message.setSubject(subject);
        message.setText(body);
        javaMailSender.send(message);
    }

}

and here is my mailer

@Controller
public class ExamPle {

    @Autowired
    private SendMail  sendMail;

    @RequestMapping("/he")
    public String homePage() {
        sendMail.sendingMail("bobobush007@gmail.com", "Welcome George", "Sample Message here");
        return "Sent";
        }
}

I already have sprint-boot-starter-mail in my pom file but i keep getting this error message. I have even watched youtube videos of tutorials on how to do this and yet it doesn't work. I am using Spring Tool Suite Version: 3.9.0.RELEASE.

I have uninstalled my jdk as well as STS and installed new copies.Now i get this error

解决方案

This works.

@Service
public class SendMail {

@Autowired
private JavaMailSender javaMailSender;

  public void sendingMail(String to, String subject, String body) {
    MimeMessage message=javaMailSender.createMimeMessage();
    MimeMessageHelper helper;
    helper=new MimeMessageHelper(message,true);
    helper.setTo(to);
    helper.setSubject(subject);
    helper.setText(body);
    javaMailSender.send(message);

 }}
