1、SpringBoot集成qq邮件

1.1、导入的依om.xml

​
<!--        引入邮件启动器： spring-boot-starter-mail-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-mail</artifactId>
        </dependency>
​
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
​
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
        </dependency>

1.2、配置文件

​
spring:
  #邮箱基本配置
  mail:
    #配置smtp服务主机地址
    # qq邮箱为smtp.qq.com          端口号465或587
    # sina    smtp.sina.cn
    # aliyun  smtp.aliyun.com
    # 163     smtp.163.com       端口号465或994
    host: smtp.qq.com
    #发送者邮箱
    username: xxxxxx@qq.com
    #配置密码,注意不是真正的密码，而是刚刚申请到的授权码
    password: xxxxxxxxx
    #端口号465或587
    port: 587
    #默认的邮件编码为UTF-8
    default-encoding: UTF-8
    #其他参数
    properties:
      mail:
        #配置SSL 加密工厂
        smtp:
          ssl:
            #本地测试，先放开ssl
            enable: false
            required: false
          #开启debug模式，这样邮件发送过程的日志会在控制台打印出来，方便排查错误
        debug: true

1.3、方法-controller

package com.lxx.service;
​
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.mail.javamail.JavaMailSenderImpl;
import org.springframework.mail.javamail.MimeMessageHelper;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
​
import javax.mail.MessagingException;
import java.util.Date;
​
@RestController
@RequestMapping("/email")
public class EmailController {
​
    /**
     * 注入邮件工具类
     */
    @Autowired
    private JavaMailSenderImpl javaMailSender;
    
    @Value("${spring.mail.username}")
    private String sendMailer;
    /**
     * 发送邮件
     * @param title 标题 （字符串）
     * @param text 主题内容（字符串）
     * @param receive 邮件的接受人（字符串）---535329006@qq.com
     * http://localhost:8080/email/sendEmail?title=标题&text=内容&receive=535329006@qq.com
     */
    @GetMapping("sendEmail")
    public void sendEmail(String title,String text,String receive) {
        try {
            //true 代表支持复杂的类型
            MimeMessageHelper mimeMessageHelper = new MimeMessageHelper(javaMailSender.createMimeMessage(),true);
            //邮件发信人
            mimeMessageHelper.setFrom(sendMailer);
            //邮件收信人
            mimeMessageHelper.setTo(receive);
            //邮件主题
            mimeMessageHelper.setSubject(title);
            //邮件内容
            mimeMessageHelper.setText(text);
            //邮件发送时间
            mimeMessageHelper.setSentDate(new Date());
            //发送邮件
            javaMailSender.send(mimeMessageHelper.getMimeMessage());
            System.out.println("发送邮件成功：" +sendMailer+"===>"+receive);
​
        } catch (MessagingException e) {
            e.printStackTrace();
            System.out.println("发送邮件失败："+e.getMessage());
        }
    }
}
