发送类实现SendMailServiceImpl.java
public class SendMailServiceImpl implements ISendMailService {
private static final Logger LOG = LogManager.getLogger(SendMailServiceImpl.class.getName());
@Autowired
private SpringTemplateEngine templateEngine;
@Override
public String sendMail(MailParameter params) {
String message = Constants.SUCCESS;
try {
//构造上下文(Model)
Context context = new Context();
context.setVariable("email", params);
//构造静态文件地址
String result = UUID.randomUUID().toString()+".html";
FileWriter write = new FileWriter(Constants.TEMP+result);
//构造模板引擎并渲染
templateEngine.process(params.getTemplate(), context, write);
params.setTemplate(result);
message = MailUtil.sendEmail(params);
} catch (Exception e) {
LOG.error("邮件：{} 发送异常{}",params.getEmail(),e);
message = Constants.FAIL;
}
return message;
}
}
当然这里只是提供了部分代码实现，比如实体类，邮件发送工具类并未罗列。还有就是关于Thymeleaf 标签的一些实用说明，网上很多，请自行百度。
