Send a simple message using the Spring message abstraction Layer

Spring provides a high-level abstraction layer for sending e-mail messages that shields the user from the details of the underlying messaging system and is responsible for low-level resource processing on behalf of the client. The main package for the spring message Abstraction layer is org.springframework.mail. It includes the primary interface for sending e-mail MailSender and the properties that encapsulate simple messages such as from, TO,CC, subject, and the value object of text called Simplemailmessage.

1. We define an interface for sending mail: Ordermanager.java

1 public interface OrderManager extends basemanager{
2/**
3 *email, email address to send;
4 *code: Activation code
5 */
6 public void PlaceOrder (String email);
7}

2, we need to implement the method of this interface: Ordermanagerimpl.java

1 Import javax.mail.Message;
2 Import javax.mail.MessagingException;
3 Import javax.mail.internet.InternetAddress;
4 Import Javax.mail.internet.MimeMessage;
5 Import org.springframework.mail.MailException;
6 Import Org.springframework.mail.javamail.JavaMailSender;
7 Import Org.springframework.mail.javamail.MimeMessagePreparator;
8 Import Service. OrderManager;
9
One public class Ordermanagerimpl extends Basemanagerimpl implements OrderManager {
12
Private Javamailsender MailSender;
Private MyMailMessage message;
15
16
Setmessage public void (Citymailmessage message)
18 {
this.message = message;
20}
public void Setmailsender (Javamailsender mailsender) {
This.mailsender = MailSender;
23}
public void PlaceOrder (final String email) {
25
26
Mimemessagepreparator preparator = new Mimemessagepreparator () {
public void Prepare (MimeMessage mimemessage) throws Messagingexception {
Mimemessage.setrecipient (Message.RecipientType.TO,
New internetaddress (email));
To Mimemessage.setfrom (New InternetAddress (Message.getfrom ()));
32/** Conversion code for gbk*/
Mimemessage.setsubject (Message.getsubject (), "GBK");
Mimemessage.settext (email+ "<br>" +message.getsubject () +message.gettext (), "GBK");
37
38}
39};
try{
Mailsender.send (Preparator);
42}
A catch (Mailexception ex) {
//log it and go on
System.err.println (Ex.getmessage ());
46}
47}
48}

3. Spring Configuration Send Email applicationcontext-email.xml

1 <?xml version= "1.0" encoding= "UTF-8"?
2! DOCTYPE beans Public "-//spring//dtd bean//en"
3 "HTTP://WWW.SPRINGFRAMEWORK.ORG/DTD/SPRING-BEANS.DTD" >
4
5 <beans>
6 <bean id= "MailSender" class= "Org.springframework.mail.javamail.JavaMailSenderImpl"
7 <property name= "host" >
8 <value> smtp.163.com </value>
9 </property>
<property name= "username" >
<value> username </value>
</property>
<property name= "Password"
<value> Password </value>
</property>
<property name= "Javamailproperties" >
<props>
<prop key= "Mail.smtp.auth" >true </prop>
<prop key= "Mail.smtp.timeout" >25000 </prop>
</props>
</property>
</bean>
23
<bean id= "MailMessage" class= "Org.springframework.mail.SimpleMailMessage"
<property name= "from"
<value> Email </value>
</property>
<property name= "Subject"
<value> title </value>
</property>
<property name= "text" >
<value> content </value>
</property>
+ </bean>
47
<bean id= "OrderManager" class= "Cn.cityyouth.service.impl.OrderManagerImpl"
<property name= "MailSender"
<ref bean= "MailSender"/>
Wuyi </property>
<property name= "message" >
<ref bean= "MailMessage"/>
</property>
</bean>
56
</beans>

4, the final configuration of their own JSP page and action

1 package cn.cityyouth.web.action;
2
3 Import javax.servlet.http.HttpServletRequest;
4 Import Javax.servlet.http.HttpServletResponse;
5 Import Org.apache.struts.action.ActionForm;
6 Import Org.apache.struts.action.ActionForward;
7 Import org.apache.struts.action.ActionMapping;
8 Import Org.apache.struts.action.ActionMessage;
9 Import org.apache.struts.action.ActionMessages;
Import Com.test.service.OrderManager;
11
public class Sendmailaction extends Baseaction {
13
14/**
* Method Execute
16 *
* @param mapping
* @param form
* @param request
* @param response
* @return Actionforward
22 */
Public Actionforward Execute (actionmapping mapping, Actionform form,
HttpServletRequest request, HttpServletResponse response) {
OrderManager omi= (OrderManager) This.getbean ("OrderManager");
String useremail= "123@163.com";
Omi.placeorder (UserEmail);
28}
29}

To this all the development to end.

The main package for the Sring message Abstraction Layer is: Org.springframework.mail package. It contains a core interface called MailSender for sending messages and a value object that contains simple message properties such as From,to,cc,subject,text called Simplemailmessage. This package also contains a hierarchy to check for exceptions that support a higher level of abstraction than the low-level mail system exception with root exception exists mailexception. Please refer to Javadocs for more information on the abnormal levels of miscellaneous messages.

Spring also supports a mailsender dedicated to JavaMail features such as MIME message sub-interfaces, named Org.springframework.javamail.JavaMailerSener. It also supports a ready callback interface for JavaMail MIME information, named Org.springframework.mail.JavaMail.MimeMessagePreparator.
