使用邮件模板(freemarker.jar)发送邮件

今天药忘吃喽~ 2022-04-11 02:48 214阅读 0赞

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>

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("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 }

4.Spring容器的配置:
