spring3框架提供了非常有用的郵件功能，org.springframework.mail 提供了對郵件的發送的jar包，最好還是自己去看一下里面的函數。spring framework提供了簡單和帶附件的郵件發送功能。
假設這是個業務邏輯層代碼，假設我們需要給客戶發送關於訂單信息的郵件
publicinterface OrderManager { void placeOrder(Order order); }
簡單郵件發送功能
import org.springframework.mail.MailException; import org.springframework.mail.MailSender; import org.springframework.mail.SimpleMailMessage; publicclass SimpleOrderManager implements OrderManager {
private MailSender mailSender;//spring 提供的一個已經封裝好的庫，具體的實現可以參考API
private SimpleMailMessage templateMessage; publicvoid setMailSender(MailSender mailSender) { this.mailSender = mailSender; } publicvoid setTemplateMessage(SimpleMailMessage templateMessage) { this.templateMessage = templateMessage; } public void placeOrder(Order order) { // Do the business calculations...// Call the collaborators to persist the order...// Create a thread safe "copy" of the template message and customize it SimpleMailMessage msg = new SimpleMailMessage(this.templateMessage); msg.setTo(order.getCustomer().getEmailAddress()); msg.setText( "Dear " + order.getCustomer().getFirstName() + order.getCustomer().getLastName() + ", thank you for placing order. Your order number is " + order.getOrderNumber()); try{ this.mailSender.send(msg); } catch(MailException ex) { // simply log it and go on... System.err.println(ex.getMessage()); } }}
xml的配置文件，當然你也可以使用註解
<beanid="mailSender"class="org.springframework.mail.javamail.JavaMailSenderImpl">
<propertyname="host"value="mail.mycompany.com"/>//郵箱的服務主機
<property name="port" value="25"/>
<property name="port" value="25" />
<property name="javaMailProperties">
<props>
<prop key="mail.smtp.auth">true</prop>
<prop key="mail.smtp.timeout">25000</prop>
</props>
</property>
<property name="username" value="**********" />//用戶名
<property name="password" value="*******"></property>//密碼
</bean> <!-- this is a template message that we can pre-load with default state --> <beanid="templateMessage"class="org.springframework.mail.SimpleMailMessage"> <property name="from"v alue="[email protected]"/>//發送者的郵箱地址 <property name="subject"value="Your order"/> </bean> <beanid="orderManager"class="com.mycompany.businessapp.support.SimpleOrderManager"> <propertyname="mailSender"ref="mailSender"/> <propertyname="templateMessage"ref="templateMessage"/> </bean>發送附件和內嵌的htm啊
JavaMail and MimeMessageHelper
1 附件的發送
JavaMailSenderImpl sender = new JavaMailSenderImpl(); MimeMessage message = sender.createMimeMessage(); // use the true flag to indicate you need a multipart message MimeMessageHelper helper = new MimeMessageHelper(message, true);//true 表示你發送的是帶有附件的郵件 helper.setTo("[email protected]"); helper.setText("Check out this image!"); // let's attach the infamous windows Sample file (this time copied to c:/)
FileSystemResource file = new FileSystemResource(new File("c:/Sample.jpg"));
//spring 2.5的版本需要
//FileSystemResource file = new FileSystemResource(new File("file:c:/Sample.jpg"));
helper.addAttachment("CoolImage.jpg", file);// helper.addAttachment(MimeUtility.encodeWord("個人申請表.pdf"),new FileSystemResource(new File(pdfP//ath)));
sender.send(message);2 發送帶有html的郵件
JavaMailSenderImpl sender = new JavaMailSenderImpl(); sender.setHost("mail.host.com"); MimeMessage message = sender.createMimeMessage(); // use the true flag to indicate you need a multipart message MimeMessageHelper helper = new MimeMessageHelper(message, true); helper.setTo("[email protected]"); // use the true flag to indicate the text included is HTML helper.setText("<html><body><img src='cid:identifier1234'></body></html>", true); // let's include the infamous windows Sample file (this time copied to c:/) FileSystemResource res = new FileSystemResource(new File("c:/Sample.jpg")); helper.addInline("identifier1234", res); sender.send(message);
