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 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:
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("[email protected]");//发送人
51 helper.setTo("[email protected]");//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 }4.Spring容器的配置:
1 <?xml version="1.0" encoding="UTF-8"?>
2 <beans
3 xmlns="http://www.springframework.org/schema/beans"
4 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
