本文实例为大家分享了SpringBoot +Mail+FreeMarker发送邮件，供大家参考，具体内容如下

通过spirngboot 自带的mail服务及FreeMarker模板引擎，发送邮

添加依赖

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-freemarker</artifactId>
</dependency>
<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.projectlombok</groupId>
<artifactId>lombok</artifactId>
<optional>true</optional>
</dependency>

在application.yml文件中配置Mail信息

spring:
mail:
port: 25
username: ${username}
password: ${password}
protocol: smtp
default-encoding: utf-8
host: ${host}

编写MailService服务

@Service
public class MailServiceImpl implements MailService {

//邮件的发送者
@Value("${spring.mail.username}")
private String from;

//注入MailSender
@Autowired
private JavaMailSender mailSender;

//发送邮件的模板引擎
@Autowired
private FreeMarkerConfigurer configurer;

/**
* @param params 发送邮件的主题对象 object
* @param title 邮件标题
* @param templateName 模板名称
*/
@Override
public void sendMessageMail(Object params, String title, String templateName) {

try {

MimeMessage mimeMessage = mailSender.createMimeMessage();
MimeMessageHelper helper = new MimeMessageHelper(mimeMessage, true);
helper.setFrom(from);
helper.setTo(InternetAddress.parse("xxxxx@163.com"));//发送给谁
helper.setSubject("【" + title + "-" + LocalDate.now() + " " + LocalTime.now().withNano(0) + "】");//邮件标题

Map<String, Object> model = new HashMap<>();
model.put("params", params);
try {
Template template = configurer.getConfiguration().getTemplate(templateName);
try {
String text = FreeMarkerTemplateUtils.processTemplateIntoString(template, model);

helper.setText(text, true);
mailSender.send(mimeMessage);
} catch (TemplateException e) {
e.printStackTrace();
}
} catch (IOException e) {
e.printStackTrace();
}
} catch (MessagingException e) {
e.printStackTrace();
}
}
}

定义发送邮件对象

发送内容为object，我这里演示一个对象，通过模板渲染方式接收内容

@Data
public class Message {

private String messageCode;
private String messageStatus;
private String cause;

}

在项目templates目录新建个message.ftl文件

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>消息通知</title>
</head>

<style type="text/css">
table {
font-family: "Trebuchet MS", Arial, Helvetica, sans-serif;
width: 100％;
border-collapse: collapse;
}

td, th {
font-size: 1em;
border: 1px solid #5B4A42;
padding: 3px 7px 2px 7px;
}

th {
font-size: 1.1em;
text-align: center;
padding-top: 5px;
padding-bottom: 4px;
background-color: #24A9E1;
color: #ffffff;
}
</style>
<body>
<div>
<h2>邮件消息通知</h2>
<table id="customers">
<tr>
<th>MessageCode</th>
<th>MessageStatus</th>
<th>Cause</th>
</tr>
<tr>
<td>${(params.messageCode)!""}</td>
<td>${(params.messageStatus)!""}</td>
<td>${(params.cause)!""}</td>
</tr>
</table>
</div>
</body>
</html>

测试邮件发送

新建controller类

@RestController
public class MailController {

@Autowired
private MailService mailService;

@RequestMapping(value = "/sendMessage", method = RequestMethod.GET)
public void sendMailMessage() {
Message message = new Message();

message.setMessageCode("MissingParameter");
message.setMessageStatus("Failed");
message.setCause("缺少参数,请确认");

mailService.sendMessageMail(message, "测试消息通知", "message.ftl");
}
}

启动服务访问 http://localhost:8080/sendMessage
