废话就不多说了，代码如上.Velocity发送邮件的代码如下:

package org.frame.base.mail;

import java.util.HashMap;
import java.util.Map;

import org.apache.velocity.app.VelocityEngine;
import org.springframework.mail.MailMessage;
import org.springframework.mail.MailSender;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.ui.velocity.VelocityEngineUtils;

public class VelocityMailService {

	MailSender mailSender;
	MailMessage mailMessage;
	String template;
	VelocityEngine velocityEngine;
	Map model = new HashMap();
	public void setMailSender(MailSender mailSender) {
		this.mailSender = mailSender;
	}
	public void setMailMessage(MailMessage mailMessage) {
		this.mailMessage = mailMessage;
	}
	public void setTemplate(String template) {
		this.template = template;
	}
	public void setVelocityEngine(VelocityEngine velocityEngine) {
		this.velocityEngine = velocityEngine;
	}

	@SuppressWarnings("unchecked")
	public void send(String subject){
		model.put("me", "杨春龙");
		mailMessage.setSubject(subject);
		mailMessage.setText(getText());
		mailSender.send((SimpleMailMessage) mailMessage);
	}

	public String getText(){
		return VelocityEngineUtils.mergeTemplateIntoString(velocityEngine, template, model);
	}

}

通过Velocity渲染后，返回邮件内容，并发送邮件
