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=[e-mail]
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("[e-mail]");
vtmm.setTitle("mail with veloctiy and spring");
vtmm.send();

 

看下是否收到邮件了。^_^
