使用Spring邮件发送Email

Spring提供了一个发送电子邮件的高级抽象层，它向用户屏蔽了底层邮件系统的一些细节，同时负责低层次的代表客户端的资源处理。Spring邮件抽象层的主要包为org.springframework.mail。它包括了发送电子邮件的主要接口MailSender和 封装了简单邮件的属性的值对象叫做SimpleMailMessage。
首先:我们定义一个发送邮件的接口:IMailManager.java
/*
* IMailManager.java
* Copyright 2005, All rights reserved.
*/
package test.mail.manager;

import test.common.logic.IManager;
import test.model.Order;

/**
* Note:this interface mainly deal with the sendOrder
*/
public interface IMailManager extends IManager{
   
    void sendOrder(Order order);
}

然后实现这个接口:MailManager.java
/*
* MailManager.java
* Copyright 2005, All rights reserved.
*/
package test.mail.manager;

import org.springframework.mail.MailException;
import org.springframework.mail.MailSender;
import org.springframework.mail.SimpleMailMessage;

import test.common.logic.impl.Manager;
import test.model.Order;

/**
* Note:the implements of IMailManager
*/
public class MailManager extends Manager implements IMailManager {
   
    private MailSender mailSender;
    private SimpleMailMessage message;

    public void sendOrder(Order order) {
        SimpleMailMessage mailMessage = new SimpleMailMessage(this.message);
        mailMessage.setTo(order.getUser().getEmail());
        mailMessage.setText("Dear"
                + order.getUser().getFirstName()
                + order.getUser().getLastName()
                + ", thank you for placing order. Your order code is "
                + order.getCode());
        try{
            mailSender.send(mailMessage);
        }catch(MailException ex) {
            System.err.println(ex.getMessage());           
        }

    }

    /**
     * @param mailSender The mailSender to set.
     */
    public void setMailSender(MailSender mailSender) {
        this.mailSender = mailSender;
    }
    /**
     * @param message The message to set.
     */
    public void setMessage(SimpleMailMessage message) {
        this.message = message;
    }
}

然后我们在Action 里面调用: SendMailAction.java
/*
* SendMail.java
* Copyright 2005, All rights reserved.
*/
package test.mail.action;

import test.common.action.BaseAction;
import test.mail.manager.IMailManager;
import test.order.dao.IOrderDao;
import test.model.Order;


/**
* Note: SendMailAction
*/
public class SendMailAction extends BaseAction {
    private IMailManager mailManager;
    private IOrderDao orderDao;
    private long orderId;
   
    public String execute() throws Exception {
        Order order = orderDao.getOrder(orderId);
        mailManager.sendOrder(order);
        return SUCCESS;
    }

   
    /**
     * @return Returns the mailManager.
     */
    public IMailManager getMailManager() {
        return mailManager;
    }
    /**
     * @param mailManager The mailManager to set.
     */
    public void setMailManager(IMailManager mailManager) {
        this.mailManager = mailManager;
    }
   
    /**
     * @return Returns the orderDao.
     */
    public IOrderDao getOrderDao() {
        return orderDao;
    }
    /**
     * @param orderDao The orderDao to set.
     */
    public void setOrderDao(IOrderDao orderDao) {
        this.orderDao = orderDao;
    }
    /**
     * @return Returns the orderId.
     */
    public long getOrderId() {
        return orderId;
    }
    /**
     * @param orderId The orderId to set.
     */
    public void setOrderId(long orderId) {
        this.orderId = orderId;
    }
}

最后的就是配置了.在ApplicationContext.xml文件里加上如下的内容:
<bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
<property name="host"><value>smtp服务器</value></property>
        <property name="username"><value>用户名</value></property>
        <property name="password"><value>密码</value></property>
/**如果服务器要求验证,加上此**/
        <property name="javaMailProperties">
            <props>
                <prop key="mail.smtp.auth">true</prop>
                <prop key="mail.smtp.timeout">25000</prop>
            </props>
        </property>
</bean>

<bean id="mailMessage"
class="org.springframework.mail.SimpleMailMessage">
<property name="from">
<value>你的电子邮件地址</value>
</property>
<property name="subject">
<value>邮件标题</value>
</property>
</bean>


<bean id="mailManager" class=" test.mail.manager.MailManager" >
<property name="mailSender">
<ref bean="mailSender" />
</property>
<property name="message">
<ref bean="mailMessage" />
</property>
</bean>
在对应的action配置文件中加入:
<bean id="SendMailAction"
class=" test.mail.action.SendMailAction" singleton="false" >
<property name="mailManager">
<ref bean="mailManager" />
</property>
<property name="orderDao">
<ref bean="orderDao"/>
</property>
</bean>

在xwork配置文件中:
<action name="sendMailBG" class="SendMailAction">
<interceptor-ref name="defaultStack" />
<result name="success" type="freemarker">success.ftl</result>
<result name="error" type="freemarker">error.ftl</result>
</action>

运行结果如下:用户163.com账户作测试:
