## 场景 ##

项目搭建专栏：

实现最简单的带标题以及文本内容的邮件发送。使用qq邮件服务器。

## 实现 ##

项目中引入邮件依赖

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

找到项目的全局配置文件application.properties

将username改为要发送邮件的账号，这里是qq邮箱账号

下面password设置为qq邮箱的授权码

#JavaMail邮件发送的配置
    #指明邮件发送服务器  如果是163的则为smtp.163.com
    spring.mail.host=smtp.qq.com
    spring.mail.username=
    #授权码qq邮箱需要设置并获取授权码  163则直接为邮箱密码
    spring.mail.password=
    spring.mail.properties.mail.smtp.auth=true
    spring.mail.properties.mail.smtp.starttls.enable=true
    spring.mail.properties.mail.smtp.starttls.required=true

qq邮箱设置授权码：

qq邮箱--设置--账户--POP3/SMTP服务

开启服务后就会获得qq的授权码

在项目下新建email包

在email包下新建配置类实现从全局配置文件中获取自定义属性

package com.example.demo.email;
    
    import org.springframework.beans.factory.annotation.Value;
    import org.springframework.stereotype.Component;
    @Component
    public class EmailConfig {
     
     @Value("${spring.mail.username}")
     private String emailFrom;
    
     public String getEmailFrom() {
      return emailFrom;
     }
    
     public void setEmailFrom(String emailFrom) {
      this.emailFrom = emailFrom;
     }
    
    }

新建接口EmailService,有一个发送邮件的方法。

package com.example.demo.email;
    
    import org.springframework.stereotype.Service;
    
    @Service
    public interface EmailService {
    
    
     void sendSimpleMail(String senfTo,String title,String content);
    }

新建接口实现类

package com.example.demo.email;
    
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.mail.SimpleMailMessage;
    import org.springframework.mail.javamail.JavaMailSender;
    import org.springframework.stereotype.Service;
    @Service
    public class EmailServiceImpl implements EmailService {
    
    
     @Autowired
     private EmailConfig emailConfig;
     
     @Autowired
     private JavaMailSender mailSender;
     
     @Override
     public void sendSimpleMail(String sendTo, String title, String content) {
      
      //简单邮件的发送
      SimpleMailMessage message = new SimpleMailMessage();
      message.setFrom(emailConfig.getEmailFrom());
      message.setTo(sendTo);
      message.setSubject(title);
      message.setText(content);
      mailSender.send(message);
     }
    
    }

通过SimpleMailMessage 设置要发送邮件的账号以及标题和内容。

然后使用JavaMailSender 实现发送邮件。

新建controller实现测试邮件发送。

package com.example.demo.email;
    
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.ResponseBody;
    
    @Controller
    public class EmailController {
    
     @Autowired
     private EmailService emailService;
     
     @RequestMapping("simpleEmail")
     @ResponseBody
     public String sendSimpleEmail() {
      emailService.sendSimpleMail("****@qq.com", "测试", "简单邮件");
      return "success";
     }
    }

sendSimpleMail方法第一个参数就是要发送的邮箱账号。

项目启动类下添加此包为可扫描。

@SpringBootApplication(scanBasePackages= {"com.example.demo.controller","com.example.demo.service","com.example.demo.interceptor","com.example.demo.handler","com.example.demo.job","com.example.demo.email"})

启动项目，访问

[http://localhost:8080/simpleEmail][http_localhost_8080_simpleEmail]

可以看到浏览器返回success，然后收到邮件。
