Spring邮件抽象层和Spring中的定时调度的整合(二)

其次: MimeMessagePreparator函数的使用

例子：

   1步：配置MailSender.xml

WEB-INF/conf/MailSender.xml



<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN"

"http://www.springframework.org/dtd/spring-beans.dtd">

<beans>

<bean id="JMSender" class="org.springframework.mail.javamail.JavaMailSenderImpl" >

     <property name="host">

         <value>mail.XXX.com</value>

     </property>

     <property name="javaMailProperties">

         <props>

            <!-- 如果要使用用户名和密码验证,这一步需要 -->

            <prop key="mail.smtp.auth">true</prop>

         </props>

     </property>

     <property name="username">

         <value>发件人的用户名</value>

     </property>

     <property name="password">

         <value>发件人的密码</value>

     </property>

  </bean>



<bean id="ordermanager" class="mail.OrderManagerImpl">

     <property name="JMSender" ref="JMSender"></property>

   

</bean>

</beans>

2步:配置web.xml



           <context-param>

        <param-name>contextConfigLocation</param-name>

        <param-value>

            <!--WEB-INF/dataAccessContext.xml,-->

            WEB-INF/conf/applicationContext.xml,

            WEB-INF/conf/MailSender.xml

        </param-value>

    </context-param>

3步: 创建类，一个JAVABEAN，一个接口，一个实现类。

package mail;



public class Customer {

  

    private String EmailAddress;

    private String FirstName;

    private String LastName;

    private String text;

  

public Customer(String emailAddress, String firstName, String lastName, String text) {

       super();

       EmailAddress = emailAddress;

       FirstName = firstName;

       LastName = lastName;

       this.text = text;

    }

    public String getEmailAddress() {

       return EmailAddress;

    }

    public void setEmailAddress(String emailAddress) {

       EmailAddress = emailAddress;

    }

    public String getFirstName() {

       return FirstName;

    }

    public void setFirstName(String firstName) {

       FirstName = firstName;

    }

    public String getLastName() {

       return LastName;

    }

    public void setLastName(String lastName) {

       LastName = lastName;

    }

    public String getText() {

       return text;

    }

    public void setText(String text) {

       this.text = text;

    }

  

}

package mail;



public interface IOrderManager {



    void placeOrder(Customer customer);

}

-------------------------------------------------------------------------------------------------------







package mail;



import javax.mail.Message;

import javax.mail.MessagingException;

import javax.mail.internet.InternetAddress;

import javax.mail.internet.MimeMessage;



import org.springframework.mail.MailException;

import org.springframework.mail.javamail.JavaMailSender;

import org.springframework.mail.javamail.MimeMessagePreparator;



public class OrderManagerImpl implements IOrderManager {



    private JavaMailSender JMSender;



    public void placeOrder(final Customer customer) {

      

       //定义一个回调函数

        MimeMessagePreparator preparator = new MimeMessagePreparator() {

      

public void prepare(MimeMessage mimeMessage) throws MessagingException {

                       //setRecipient设置收件人的地址。

         mimeMessage.setRecipient(Message.RecipientType.TO,

                        new InternetAddress(customer.getEmailAddress()));

//setFrom设置发件人的地址。

mimeMessage.setFrom(new InternetAddress("[e-mail]"));

           //setText 设置邮件内容。

                mimeMessage.setText(

                    "Dear "

                        + customer.getFirstName()

                        + customer.getLastName()

                        + ", thank you ！. "

                        );

              //setSubject 设置邮件标题。

                mimeMessage.setSubject("FOR TEST!!");

            }

        };

        try {

        JMSender.send(preparator);

        }

        catch (MailException ex) {

            //log it and go on

            System.err.println(ex.getMessage());          

        }

    }

    public JavaMailSender getJMSender() {

       return JMSender;

    }



    public void setJMSender(JavaMailSender sender) {

       JMSender = sender;

    }

}

再写以上的类的时候，要加Javamail.jar,关于Javamail.jar的具体信息，可以查一下互联网。

好了，邮件抽象层已经写完了，现在开始写Spring的定时调度。
