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
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("[email protected]");//发送人
51 helper.setTo("1875[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" 5 xmlns:p="http://www.springframework.org/schema/p" 6 xsi:schemaLocation="http://www.springframework.org/schema/beans 7 http://www.springframework.org/schema/beans/spring-beans-3.1.xsd"> 8 9 <bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl"> 10 <property name="host" value="smtp.163.com"></property> <!-- 服务器名 --> 11 <property name="port" value="25"></property> <!-- 端口号 --> 12 <property name="username" value="13599057417"></property><!-- 用户名 --> 13 <property name="password" value="luofuxiang"></property><!-- 密码 --> 14 <property name="protocol" value="smtp"></property> <!-- 协议 --> 15 <property name="defaultEncoding" value="utf-8"></property> 16 <property name="javaMailProperties"> 17 <props> 18 <prop key="mail.smtp.auth">true</prop> 19 </props> 20 </property> 21 </bean> 22 <bean id="freeMarkerConfiguration" class="org.springframework.ui.freemarker.FreeMarkerConfigurationFactoryBean"> 23 <property name="templateLoaderPath" value="/cn/bd/mail/template"></property> <!-- 指定模板(mail.ftl)路径 --> 24 <!-- 设置FreeMarker环境变量 --> 25 <property name="freemarkerSettings"> 26 <props> 27 <prop key="default_encoding">UTF-8</prop> 28 </props> 29 </property> 30 </bean> 31 <!-- 配置bean:MailService --> 32 <bean id="mailService" class="cn.bd.mail.template.MailService"> 33 <property name="mailSender" ref="mailSender"></property><!-- 为属性注入值 --> 34 <property name="freeMarkerConfiguration" ref="freeMarkerConfiguration"></property><!-- 给属性注入值 --> 35 </bean> 36 </beans>
