send email with velocity and spring 完整示例

    由于项目里要发邮件，用了spring 和 velocity 模板。写下来以后可以看，好记性不如博客。
版本说明下：
spring 2.0.6
velocity 1.5
javamail 用 spring/lib下的

1.封装邮件信息类：

package  com.chenlb.mail;

import  java.util.Map;

import  javax.mail.MessagingException;
import  javax.mail.internet.MimeMessage;

import  org.apache.commons.logging.Log;
import  org.apache.commons.logging.LogFactory;
import  org.apache.velocity.app.VelocityEngine;
import  org.springframework.mail.MailException;
import  org.springframework.mail.javamail.JavaMailSender;
import  org.springframework.mail.javamail.MimeMessageHelper;
import  org.springframework.ui.velocity.VelocityEngineUtils;

/**
 * 邮件发送器
 * @作者 chenlb
 * @创建时间 2007-7-28 下午03:35:31 
  */
public   class  VelocityTemplateMailMessage {

     protected   final  Log logger  =  LogFactory.getLog(getClass());
    
     private  JavaMailSender javaMailSender;
     private  VelocityEngine velocityEngine;
     private  String from;
     private  String title;
     private  String encoding;
     private  String templateLocation;
     private  String[] toEmails;
     private  Map model;


     public   boolean  send() {
        MimeMessage msg  =  javaMailSender.createMimeMessage();
        MimeMessageHelper helper  =   new  MimeMessageHelper(msg);
        
         try  {
            helper.setFrom(from);
            helper.setSubject(title);
            helper.setTo(toEmails);
            helper.setText(getMessage(),  true );   //如果发的不是html内容去掉true参数
            javaMailSender.send(msg);
            
        }  catch  (MessagingException e) {
             //  TODO 自动生成 catch 块
             if (logger.isWarnEnabled()) {
                logger.warn( " 邮件信息导常! 邮件标题为:  " + title);
            }
             return   false ;
             // e.printStackTrace();
        }  catch  (MailException me) {
             //  TODO: handle exception
             if (logger.isWarnEnabled()) {
                logger.warn( " 发送邮件失败! 邮件标题为:  " + title);
            }
             return   false ;
        }
         return   true ;    
    }
    
    
     /**
     * 邮件模板中得到信息
     *  @return  返回特发送的内容
      */
     private  String getMessage() {
         return  VelocityEngineUtils.mergeTemplateIntoString(velocityEngine, 
                templateLocation, encoding, model);
    }

     private  String[] createToEmail(String to) {
         return   new  String[] {to};
    }
    
     public   void  setToEmail(String to) {
        setToEmails(createToEmail(to));
    }
    
     public   void  setJavaMailSender(JavaMailSender javaMailSender) {
         this .javaMailSender  =  javaMailSender;
    }
    
     public   void  setVelocityEngine(VelocityEngine velocityEngine) {
         this .velocityEngine  =  velocityEngine;
    }

     public   void  setEncoding(String encoding) {
         this .encoding  =  encoding;
    }

     public   void  setModel(Map model) {
         this .model  =  model;
    }

     public   void  setTemplateLocation(String templateLocation) {
         this .templateLocation  =  templateLocation;
    }

     public   void  setTitle(String title) {
         this .title  =  title;
    }

     public   void  setToEmails(String[] toEmails) {
         this .toEmails  =  toEmails;
    }

     public   void  setFrom(String from) {
         this .from  =  from;
    }

     public  String getTemplateLocation() {
         return  templateLocation;
    }
}

2.spring配置文件，applictionContext-mail.xml：

<? xml version="1.0" encoding="UTF-8" ?>
<! DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN 2.0//EN"
        "dtd/spring-beans-2.0.dtd" >
<!--  http://www.springframework.org/  -->
< beans >

<!--  属性文件加载  -->
     < bean  id ="propertyConfigurer"  class ="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer" >
         < property  name ="locations" >
           < list >
               < value > classpath:mail.properties </ value >
           </ list >
       </ property >
     </ bean >

<!--  邮件发送器  -->
     < bean  id ="mailSender"  class ="org.springframework.mail.javamail.JavaMailSenderImpl" >
         < property  name ="host"  value ="${mail.host}"   />
         < property  name ="username"  value ="${mail.username}"   />
         < property  name ="password"  value ="${mail.password}"   />
         < property  name ="defaultEncoding"  value ="UTF-8" ></ property >
         < property  name ="javaMailProperties" >
             < props >
                 < prop  key ="mail.smtp.auth" > ${mail.smtp.auth} </ prop >
                 < prop  key ="mail.smtp.timeout" > ${mail.smtp.timeout} </ prop >
             </ props >
         </ property >
     </ bean >
    
     < bean  id ="velocityEngine"  class ="org.springframework.ui.velocity.VelocityEngineFactoryBean" >
         < property  name ="resourceLoaderPath"  value ="classpath:velocity" ></ property >
     </ bean >
    
     < bean  id ="templateMail"  class ="com.chenlb.mail.VelocityTemplateMailMessage" >
         < property  name ="javaMailSender"  ref ="mailSender" ></ property >
         < property  name ="from"  value ="${mail.from}" ></ property >
         < property  name ="encoding"  value ="UTF-8" ></ property >
         < property  name ="templateLocation"  value ="test.vm" ></ property >
         < property  name ="velocityEngine"  ref ="velocityEngine" ></ property >
         < property  name ="title"  value ="wwww.blogjava.net/chenlb" ></ property >
     </ bean >
    
</ beans >

说明：模板文件放到classpath的velocity目录下，可自行改。

3.发送者邮件信息，mail.properties(classpath位置)：

mail.from = yourname@ 126 .com
mail.host = smtp .126 .com
mail.password = yourpassword
mail.smtp.auth = true
mail.smtp.timeout = 25000
mail.username = yourname

4.模板文件，text.vm(classpath的velocity目录下)：

你好！${me} 这是模板生成的邮件。

5.使用：

VelocityTemplateMailMessage vtmm  =  (VelocityTemplateMailMessage) context.getBean( " templateMail " );
Map < String, String >  data  =   new  HashMap < String, String > ();
data( " me " , " yourname " );
vtmm.setModel(data);
vtmm.setToMail( " [email protected] " );
vtmm.setTitle( " mail with veloctiy and spring " );
vtmm.send();

 

看下是否收到邮件了。^_^
