（十八）SpringBoot之发送QQ邮件

一、引入maven依赖

    <dependencies>
        <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-tomcat</artifactId>
            <scope>provided</scope>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
    </dependencies>

二、配置application.properties

spring.mail.host=smtp.qq.com
spring.mail.username=邮箱名
spring.mail.password=这里填邮箱的授权码
spring.mail.default-encoding=UTF-8
spring.mail.port=465
spring.mail.properties.mail.smtp.socketFactory.class=javax.net.ssl.SSLSocketFactory
spring.mail.properties.mail.debug=true

• 注意：

1. PO3/SMTP服务必须开启

　　2.QQ邮箱发送邮件服务器主机名为：smtp.qq.com，必须使用使用SSL（spring.mail.properties.mail.smtp.socketFactory.class=javax.net.ssl.SSLSocketFactory），端口号465或587（spring.mail.port=465）

 3. 发送邮件

package com.shyroke.controller;

import javax.mail.internet.MimeMessage;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.MimeMessageHelper;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping("/mail")
public class MailController {
    @Autowired
    JavaMailSender mailSender;

    @ResponseBody
    @RequestMapping("/send")
    public Object sendEmail() {
        try {
            final MimeMessage mimeMessage = this.mailSender.createMimeMessage();
            final MimeMessageHelper message = new MimeMessageHelper(mimeMessage);
            message.setFrom("qweyhj@qq.com");
            message.setTo("865386512@qq.com");
            message.setSubject("测试邮件主题");
            message.setText("测试邮件内容");
            this.mailSender.send(mimeMessage);

            return "sucesss";
        } catch (Exception ex) {
            ex.printStackTrace();
            return "error";
        }
    }
}

 4. 结果
