使用邮件模板(freemarker.jar)发送邮件

2024-09-13 05:00:58   214人阅读

1.把freemarker.jar架包添加到项目中

2.创建模板文件,以*.ftl(后缀名是ftl)命名,模板示例如下

 1 <html>
 2 <head>
 3     <meta http-equiv="content-type" content="text/html;charset=utf-8">
 4 </head>
 5 <body>
 6     <font color="blue" size="4" face="Arial">
 7      尊敬的${user}：
 8     </font>
 9     <br/><br/>
10         <font color="blue" size="4" face="Arial">
11         &nbsp;&nbsp;恭喜您使用系统！请保管您的账号，如果登录时忘记密码
12         可以在网站登录页找回。<br/>
13         <br/><br/>系统管理员
14         </font>
15 </body>
16 </html>

 

3.发送邮件示例

 1 package cn.bd.mail.template;
 2 
 3 import java.io.IOException;
 4 import java.util.HashMap;
 5 import java.util.Map;
 6 
 7 import javax.mail.MessagingException;
 8 import javax.mail.internet.MimeMessage;
 9 
10 import org.springframework.mail.javamail.JavaMailSender;
11 import org.springframework.mail.javamail.MimeMessageHelper;
12 import org.springframework.ui.freemarker.FreeMarkerTemplateUtils;
13 import freemarker.template.Configuration;
14 import freemarker.template.Template;
15 import freemarker.template.TemplateException;
16 
17 public class MailService {
18     private JavaMailSender mailSender;
19     private Configuration freeMarkerConfiguration;
20     public void setMailSender(JavaMailSender mailSender) {
21         this.mailSender = mailSender;
22     }
23     public void setFreeMarkerConfiguration(Configuration freeMarkerConfiguration) {
24         this.freeMarkerConfiguration = freeMarkerConfiguration;
25     }
26     
27     private String getMailText(){
28         String htmlText="";
29         try{
30             //获取模板实例
31             Template template=freeMarkerConfiguration.getTemplate("mail.ftl");//mail.ftl就是模板文件
32             //通过Map传递动态数据
33             Map map=new HashMap();
34             map.put("user", "测试");
35             //解析模板文件
36             htmlText=FreeMarkerTemplateUtils.processTemplateIntoString(template, map);
37         }catch(IOException e){
38             e.printStackTrace();
39         }catch(TemplateException e){
40             e.printStackTrace();
41         }catch(Exception e){
42             e.printStackTrace();
43         }
44         return htmlText;
45     }
46     
47     public void sendMail() throws MessagingException{
48         MimeMessage mimeMessage=mailSender.createMimeMessage();
49         MimeMessageHelper helper=new MimeMessageHelper(mimeMessage,true,"UTF-8");
50         helper.setFrom("13599057417@163.com");//发送人
51         helper.setTo("1875285657@qq.com");//邮件接收人
52         helper.setSubject("标题....");
53         helper.setText(getMailText(),true);//设置HTML格式邮件内容
54         mailSender.send(mimeMessage);
55     }
56     
57 }
