spring boot 发送邮箱

此篇介绍 spring boot 集成 email 发送邮箱 这里 用的是qq邮箱  
添加 maven 依赖

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

添加配置文件：

spring:
    
      mail: 
        host: smtp.qq.com
        #你的QQ邮箱账户
        username: 1355605391@qq.com
        #你的QQ邮箱第三方授权码
        password: xxx
        #编码类型
        default-encoding: UTF-8

QQ邮箱第三方授权码 需要在 QQ邮箱获取  
需要在 设置中找到账户的最下面

一般开启第一个就可以了

我这 创建了 server 和 controller 目的为了配合 swagger 使用

@Service
    public class EmailServer {
    
    	@Autowired
        private JavaMailSender mailSender;
    	
    	@Value("${spring.mail.username}")
        private String from;
    	
    	//普通邮件
    	public Map<String, Object> sendToEmail(String to, String title, String content) {
    		Map<String, Object> mp = new HashMap<String, Object>();
    		SimpleMailMessage message = new SimpleMailMessage();
    		if(to != null && title != null && content != null) {
    			try {
    				message.setTo(to);//收信人
    		        message.setSubject(title);//主题
    		        message.setText(content);//内容
    		        message.setFrom(from);//发信人
    		        mailSender.send(message);
    		        mp.put("msg", 200);
    			} catch (Exception e) {
    				mp.put("msg", 500);
    			}
    		}else {
    	        mp.put("msg", 1017);
    		}
            return mp;
    	}
    	//HTML邮件
    	public Map<String, Object> sendToHTMLEmail(String to, String title, String content) {
    		Map<String, Object> mp = new HashMap<String, Object>();
    		if(to != null && title != null && content != null) {
    			try {
    				MimeMessage message = mailSender.createMimeMessage();
    		        MimeMessageHelper helper = new MimeMessageHelper(message, true);
    	            helper.setTo(to);
    	            helper.setSubject(title);
    	            helper.setText(content, true);//true代表支持html
    	            helper.setFrom(from);
    	            mailSender.send(message);
    		        mp.put("msg", 200);
    			} catch (Exception e) {
    				mp.put("msg", 500);
    			}
    		}else {
    	        mp.put("msg", 1017);
    		}
            return mp;
    	}
    	
    }

@RestController
    @RequestMapping("/email")
    @Api(tags = "邮件相关接口")
    @CrossOrigin(origins = "*", maxAge = 3600)
    public class EmailController{
    
    	@Autowired
    	protected EmailServer email;//邮箱
    	
    	@ApiOperation(value="发送简单邮箱")
        @PostMapping("/sendToEmail")
        public Map<String, Object> sendToEmail(@RequestBody Map<String, Object> map) {
            return email.sendToEmail((String)map.get("to"), (String)map.get("title"), (String)map.get("content"));
        }
    
    	@ApiOperation(value="发送HTML邮箱")
        @PostMapping("/sendToHTMLEmail")
        public Map<String, Object> sendToHTMLEmail(@RequestBody Map<String, Object> map) {
            return email.sendToHTMLEmail((String)map.get("to"), (String)map.get("title"), (String)map.get("content"));
        }
    	
    }

[推荐一个比较全的spring boot 发送邮箱][spring boot]

//发送图片需要添加
                    File file = new File("img_url");
                 FileSystemResource res = new FileSystemResource(file);
                 helper.addInline("001", res);
     
                    //测试时加入 <img width='250px' src='cid:001'>
