java利用模板发送邮件_SpringBoot使用FreeMarker模板发送邮件

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

org.springframework.boot

spring-boot-starter-freemarker

org.springframework.boot

spring-boot-starter-mail

org.springframework.boot

spring-boot-starter-web

org.projectlombok

lombok

true

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"));//发送给谁

helper.setSubject("【" + title + "-" + LocalDate.now() + " " + LocalTime.now().withNano(0) + "】");//邮件标题

Map 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

消息通知

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;

}

邮件消息通知

MessageCode	MessageStatus	Cause
${(params.messageCode)!""}	${(params.messageStatus)!""}	${(params.cause)!""}

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
