# 目的：springboot2.0-发送邮箱。QQ、网易邮箱 #

###  第一步：添加依赖【网上都是说添一种依赖这是错误的，会出现注入的时候为null】 ###

<dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-mail</artifactId>
            </dependency>
            <dependency>
                <groupId>org.springframework</groupId>
                <artifactId>spring-context-support</artifactId>
                <version>4.3.7.RELEASE</version>
            </dependency>

### 第二步、配置application.yml  ###

**注意:下面的password，并不是你的邮箱登陆密码**，而是

**2-1:126邮箱配置**

spring:
         #邮箱配置
        mail:
            host: smtp.126.com
            #发送者邮箱账号
            username: xdxBlog@126.com
            #发送者密钥
            password: xxxxxxxx
            default-encoding: utf-8
            port: 465
            properties:
                mail:
                    debug:
                        true
                    smtp:
                        socketFactory:
                            class: javax.net.ssl.SSLSocketFactory

**2-2：qq邮箱配置**

spring:
         #邮箱配置
        mail:
            host: smtp.qq.com
            #发送者邮箱账号
            username: 11111111@qq.com
            #发送者密码
            password: xxxxxxx
            default-encoding: utf-8
            port: 465
            properties:
                mail:
                    debug:
                        true
                    smtp:
                        socketFactory:
                            class: javax.net.ssl.SSLSocketFactory

### 第三步：开启你的 POP3/SMTP/IMAP ###

以网易邮箱为例（自行去百度 QQ邮箱的这个很简单就百度的到）

###  第四步：测试 ###

package com.xdx97.backstage.utils;
    
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.mail.SimpleMailMessage;
    import org.springframework.mail.javamail.JavaMailSender;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RestController;
    
    //发送邮箱
    @RestController
    public class SendMail {
    
        @Autowired
        private JavaMailSender jms; //自动注入的Bean
    
        @RequestMapping(value = "/bb")
        public String sendMail(){
    //        JavaMailSenderImpl jms = new JavaMailSenderImpl();
            //建立邮件消息
            SimpleMailMessage mainMessage = new SimpleMailMessage();
            //发送者
            mainMessage.setFrom("xdxBlog@126.com");
            //接收者
            mainMessage.setTo("1455465841@qq.com");
            //发送的标题
            mainMessage.setSubject("用来测试的");
            //发送的内容
            mainMessage.setText("这是邮件");
            jms.send(mainMessage);
            return "1";
        }
    
    }

注意：

在这里你可能遇到这么一个错   Couldn't connect to host, port: localhost, 25; timeout -1;
