Spring email使用Velocity作为模板應用

發送纯文本的郵件：

备注：velocity为classpath中存放模板的文件夹

velocity中存在的email模板text.vm

text.vm内容如下：

你好！${me} 这是模板生成的邮件。

 

 

重点代码如下：

package cn.com.unusap.unutrip.spring.email;

import java.util.Map;

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.apache.velocity.app.VelocityEngine;
import org.apache.velocity.exception.VelocityException;
import org.springframework.mail.MailSender;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.ui.velocity.VelocityEngineUtils;

/**

 * @author longgangbai
 *
 */
public class VelocityTemplateMailMessage {

 protected static final Log log = LogFactory
   .getLog(VelocityTemplateMailMessage.class);

 private MailSender mailSender;

 private SimpleMailMessage message;

 private VelocityEngine velocityEngine;

 public void setVelocityEngine(VelocityEngine velocityEngine) {
  this.velocityEngine = velocityEngine;
 }

 public void setMailSender(MailSender mailSender) {
  this.mailSender = mailSender;
 }

 public void setMessage(SimpleMailMessage message) {
  this.message = message;
 }

 public void sendEmail(Map model) {
  message.setTo("[e-mail]");
  message.setSubject("subject");
  String result = null;
  try {
   result = VelocityEngineUtils.mergeTemplateIntoString(
     velocityEngine, "/velocity/text.vm", model);

//model存储模板中使用的对象的
  } catch (VelocityException e) {
   e.printStackTrace();
  }
  message.setText(result);
  mailSender.send(message);
 }
}

 

applicationContext-velocity.xml配置如下

</beans>

 

测试代码：

ApplicationContext appctx = new ClassPathXmlApplicationContext(
    "/applicationContext-velocity.xml");
  RegistrationService vtmm = (RegistrationService) appctx
    .getBean("registrationService");
  Order order = new Order();
  order.setContent("xiao bai");
  order.setDate(new Date());
  order.setEmail("[e-mail]");
  order.setOrderId("N0001");
  order.setUsername("wu xiaochao ");
  vtmm.register(order);

 

郵件配置：

classpath路径下mail.properties内容如下：

mail.from=[e-mail]
mail.host=mail.xxx.com
mail.password=xxxx
mail.smtp.auth=true
mail.smtp.timeout=25000
mail.username=xxxxx
