《SpringBoot2.X心法总纲》

场景：用户角度就是授权登陆注册等...开发角度就是线上的项目发现bug异常，立即给开发发送bug到邮箱，快速发现问题解决问题。

1、pom依赖

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

2、application.properties

#mail
spring.mail.host=smtp.163.com
spring.mail.port=25
spring.mail.username=cj_javagopython@163.com
spring.mail.password=love15176305031

3、mail配置

import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.JavaMailSenderImpl;
/**
 * @Author:MuJiuTian
 * @Description: 邮件配置
 * @Date: Created in 下午3:04 2019/11/18
 */
@Configuration
@ConfigurationProperties(prefix = "spring.mail")
public class EmailConfig {
    private String host;
    private Integer port;
    private String username;
    private String password;
    @Bean
    public JavaMailSender javaMailSender() {
        JavaMailSenderImpl javaMailSender = new JavaMailSenderImpl();
        javaMailSender.setHost(host);
        javaMailSender.setPort(port);
        javaMailSender.setUsername(username);
        javaMailSender.setPassword(password);
        return javaMailSender;
    }
    public void setHost(String host) {
        this.host = host;
    }
    public void setPort(Integer port) {
        this.port = port;
    }
    public void setUsername(String username) {
        this.username = username;
    }
    public void setPassword(String password) {
        this.password = password;
    }
}

3、Service实现

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.MimeMessageHelper;
import org.springframework.stereotype.Service;
import javax.mail.MessagingException;
import javax.mail.internet.MimeMessage;
import java.io.File;
@Service
public class MailService {
    @Value("${spring.mail.username}")
    private String setFrom;
    @Autowired
    JavaMailSender javaMailSender;
    /**
     * 纯文本的 Email 在于构造 SimpleMailMessage 实例
     * @param setTo 收件人
     * @param mailTitle 邮件标题
     * @param mailContent 邮件内容
     */
    public void sendSimpleEmail(String setTo, String mailTitle, String mailContent) {
        // 构造Email消息
        SimpleMailMessage message = new SimpleMailMessage();
        message.setFrom(setFrom);
        message.setTo(setTo);
        message.setSubject(mailTitle);
        message.setText(mailContent);
        javaMailSender.send(message);
    }
    /**
     * 附件邮件发送
     * @param setTo 手机人地址
     * @param mailTitle 附件邮件主题
     * @param mailContent 附件邮件内容
     * @throws MessagingException
     */
    public void mimeEmail(String setTo, String mailTitle, String mailContent, File file) throws MessagingException {
        // MimeMessage 本身的 API 有些笨重，我们可以使用 MimeMessageHelper
        MimeMessage mimeMessage = javaMailSender.createMimeMessage();
        // 第二个参数是 true ，表明这个消息是 multipart类型的/
        MimeMessageHelper mimeMessageHelper = new MimeMessageHelper(mimeMessage, true);
        mimeMessageHelper.setFrom(setFrom);
        mimeMessageHelper.setTo(setTo);
        mimeMessageHelper.setSubject(mailTitle);
        mimeMessageHelper.setText(mailContent);
        //添加附件,第一个参数表示添加到 Email 中附件的名称，第二个参数是图片资源
        mimeMessageHelper.addAttachment("mail.png", file);
        javaMailSender.send(mimeMessage);
    }
    /**
     * 富文本发送，这个方法里面的参数根据自己的实际情况改变
     */
    public void htmlEmail(String setTo, String mailTitle, String mailContent, File file) throws MessagingException {
        // MimeMessage 本身的 API 有些笨重，我们可以使用 MimeMessageHelper
        MimeMessage mimeMessage = javaMailSender.createMimeMessage();
        // 第二个参数是 true ，表明这个消息是 multipart类型的,第三个防止中文乱码
        MimeMessageHelper mimeMessageHelper = new MimeMessageHelper(mimeMessage, true,"UTF-8");
        mimeMessageHelper.setFrom(setFrom);
        mimeMessageHelper.setTo(setTo);
        mimeMessageHelper.setSubject(mailTitle);
        StringBuilder html = new StringBuilder();
        html.append("<h1>SpirngBoot测试邮件HTML</h1>")
                .append(""<p style="color:#F00">"+mailContent+"</p>")
                .append("<p style="text-align:right">右对齐</p>");
        mimeMessageHelper.setText(html.toString(), true);
        //添加附件,第一个参数表示添加到 Email 中附件的名称，第二个参数是图片资源
        mimeMessageHelper.addAttachment("boot.png", file);
        javaMailSender.send(mimeMessage);
    }
}

4、Controller测试

@Autowired
MailService mailService;
/**
 * mail 邮件发送测试
 * @param type 1：简单发送 2：附件发送 3：富文本发送
 * @throws MessagingException
 */
@GetMapping(value = "/mail")
public String mail(int type) throws MessagingException {
    String setTo = "mdxlcj@qq.com";
    String mailTitle = "邮箱个人简介";
    String mailContent = "hhh，我是邮件的主要内容";
    File file = new File("/Users/tentsuuhou/git/tssd/src/main/resources/static/images/tssd.png");
    if (type == 1){
        mailService.sendSimpleEmail(setTo, mailTitle, mailContent);
    } else if (type == 2){
        mailService.mimeEmail(setTo, mailTitle, mailContent,file);
    } else {
        mailService.htmlEmail(setTo,mailTitle,mailContent,file);
    }
    return "sci";
}
