备忘录：使用Spring发送各种类型的邮件，经测试，发送方和接收方可以是gmail，163。
当发送方是gmail时，设置有点不同。
Spring的设置：
<!-- Activates annotation-based bean configuration --> <!-- <context:component-scan base-package="com.aboy" /> --> <!-- JavaMailSender --> <!-- <bean id="javaMailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl"> <property name="host" value="smtp.163.com" /> <property name="username" value="obullxl@163.com" /> <property name="password" value="********" /> <property name="javaMailProperties"> <props> <prop key="mail.smtp.auth">true</prop> <prop key="mail.smtp.timeout">25000</prop> </props> </property> </bean> --> <bean id="javaMailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl"> <property name="host" value="smtp.gmail.com" /> <property name="username" value="obullxl@gmail.com" /> <property name="password" value="********" /> <property name="javaMailProperties"> <props> <prop key="mail.smtp.auth">true</prop> <prop key="mail.smtp.timeout">25000</prop> <prop key="mail.smtp.port">465</prop> <prop key="mail.smtp.socketFactory.port">465</prop> <prop key="mail.smtp.socketFactory.fallback">false</prop> <prop key="mail.smtp.socketFactory.class">javax.net.ssl.SSLSocketFactory</prop> </props> </property> </bean> <!-- 简单的message --> <bean id="mailMessage" class="org.springframework.mail.SimpleMailMessage"> <property name="to" value="obullxl@163.com" /> <property name="from" value="obullxl@gmail.com" /> <property name="subject" value="测试邮件" /> </bean> <!-- MimeMessage --> <bean id="mimeMessage" class="javax.mail.internet.MimeMessage" factory-bean="javaMailSender" factory-method="createMimeMessage" />
上面的设置中，第一个JavaMailSender的发送方为163邮箱，后面的一个为gmail邮箱的。
下面是单元测试代码：
private JavaMailSender mailSender;
private MailMessage mailMessage;
private MimeMessage mimeMessage;
@Before
public void setUp() {
ApplicationContext context = new ClassPathXmlApplicationContext("META-INF/spring/mail-context.xml");
Assert.notNull(context);
this.mailSender = context.getBean(JavaMailSender.class);
this.mailMessage = context.getBean(MailMessage.class);
this.mimeMessage = context.getBean(MimeMessage.class);
Assert.notNull(this.mailSender);
Assert.notNull(this.mailMessage);
Assert.notNull(this.mimeMessage);
}
/**
* 普通文本邮件
*/
@Test
public void testSendPlainTextMail() {
this.mailMessage.setSubject("普通文本邮件");
this.mailMessage.setText("测试Spring发送Email.");
try {
mailSender.send((SimpleMailMessage) this.mailMessage);
} catch (MailException e) {
System.out.println("Oops: 发送Email失败了....");
e.printStackTrace();
}
}
/**
* HTML格式邮件
* @throws MessagingException
*/
@Test
public void testSendHTMLMail() throws MessagingException {
MimeMessageHelper messageHelper = new MimeMessageHelper(this.mimeMessage, true, "UTF-8");
messageHelper.setTo("obullxl@163.com");
messageHelper.setFrom("obullxl@gmail.com");
messageHelper.setSubject("HTML格式邮件");
messageHelper.setText("<html><head></head><body><h2>Hello! Spring!</h2><b>XXX（中国）信息技术有限公司</b></body></html>", true);
this.mailSender.send(this.mimeMessage);
}
/**
* 带附件的HTML格式邮件
* @throws MessagingException
*/
@Test
public void testSetAttachMail() throws MessagingException {
MimeMessageHelper messageHelper = new MimeMessageHelper(this.mimeMessage, true, "UTF-8");
messageHelper.setTo("obullxl@163.com");
messageHelper.setFrom("obullxl@gmail.com");
messageHelper.setSubject("带附件的HTML格式邮件");
messageHelper.setText("<html><head></head><body><h2>Hello! Spring!</h2><b>XXX（中国）信息技术有限公司</b></body></html>", true);
FileSystemResource file = new FileSystemResource(new File("E:/Study/Spring/Spring-Validator.jpg")); // 根据个人情况设置
messageHelper.addInline("SpringValidator", file);
messageHelper.addAttachment("SpringValidator", file);
ClassPathResource resource = new ClassPathResource("jbpm.cfg.xml"); // 根据个人情况设置
messageHelper.addInline("jbpm.cfg.xml", resource);
messageHelper.addAttachment("jbpm.cfg.xml", resource);
this.mailSender.send(this.mimeMessage);
}
