使用Spring JavaMail发送邮件
一直以来都是用javax.mail来写email发送，看了spring的javamail之后才知道javax.mail臃肿繁杂。
下面总结一下spring javamail的应用：
首先导入使用jar包：activation.jar，commons-logging-1.0.4.jar，mail.jar，spring.jar
1、使用xml配置javamail：
在classpath底下新建application-mail.xml，内容如下：
1.<?xml version="1.0" encoding="UTF-8"?> 2.<beans xmlns="http://www.springframework.org/schema/beans" 3. xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 4. xmlns:aop="http://www.springframework.org/schema/aop" 5. xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd 6. http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd"> 7. <!-- 注意:这里的参数(如用户名、密码)都是针对邮件发送者的 --> 8. <bean id="mailSender" 9. class="org.springframework.mail.javamail.JavaMailSenderImpl"> 10. <property name="host"> 11. <value>smtp.163.com</value> 12. </property> 13. <property name="javaMailProperties"> 14. <props> 15. <prop key="mail.smtp.auth">true</prop> 16. <prop key="mail.smtp.timeout">25000</prop> 17. </props> 18. </property> 19. <property name="username"> 20. <value>[email protected]</value> 21. </property> 22. <property name="password"> 23. <value>xxxxxx</value> 24. </property> 25. </bean> 26.</beans>
2、发送Email类
1.public class SendMail {
2. public ApplicationContext ctx = null;
3. public SendMail() {
4. //获取上下文
5. ctx = new ClassPathXmlApplicationContext("applicationContext-mail.xml");
6. }
7. public void send() {
8. //获取JavaMailSender bean
9. JavaMailSender sender = (JavaMailSender) ctx.getBean("mailSender");
10. SimpleMailMessage mail = new SimpleMailMessage(); //<SPAN style="COLOR: #ff0000">注意SimpleMailMessage只能用来发送text格式的邮件</SPAN>
11.
12. try {
13. mail.setTo("[email protected]");//接受者
14. mail.setFrom("[email protected]");//发送者,这里还可以另起Email别名，不用和xml里的username一致
15. mail.setSubject("spring mail test!");//主题
16. mail.setText("springMail的简单发送测试");//邮件内容
17. sender.send(mail);
18. } catch (Exception e) {
19. e.printStackTrace();
20. }
21. }
发送html格式的Email：
1.public class SendMail {
2. public ApplicationContext ctx = null;
3. public SendMail() {
4. //获取上下文
5. ctx = new ClassPathXmlApplicationContext("applicationContext.xml");
6. }
7. public void send() {
8. //获取JavaMailSender bean
9. JavaMailSender sender = (JavaMailSender) ctx.getBean("mailSender");
10. JavaMailSenderImpl senderImpl = new JavaMailSenderImpl();
11. MimeMessage mailMessage = senderImpl.createMimeMessage();
12. //设置utf-8或GBK编码，否则邮件会有乱码
13. MimeMessageHelper messageHelper = new MimeMessageHelper(mailMessage,true,"utf-8");
14. try {
15. messageHelper.setTo(email.getEmail());//接受者
16. messageHelper.setFrom("[email protected]");//发送者
17. messageHelper.setSubject("测试邮件");//主题
18. //邮件内容，注意加参数true，表示启用html格式
19. messageHelper.setText("<html><head></head><body><h1>hello!!chao.wang</h1></body></html>",true);
20. sender.send(mailMessage);
21. } catch (Exception e) {
22. e.printStackTrace();
23. }
24. }
发送html格式并带有附件的Email：
1.public class SendMail {
2. public ApplicationContext ctx = null;
3. public SendMail() {
4. //获取上下文
5. ctx = new ClassPathXmlApplicationContext("applicationContext.xml");
6. }
7. public void send() {
8. //获取JavaMailSender bean
9. JavaMailSender sender = (JavaMailSender) ctx.getBean("mailSender");
10. JavaMailSenderImpl senderImpl = new JavaMailSenderImpl();
11. MimeMessage mailMessage = senderImpl.createMimeMessage();
12. //设置utf-8或GBK编码，否则邮件会有乱码
13. MimeMessageHelper messageHelper = new MimeMessageHelper(mailMessage,true,"utf-8");
14. try {
15. messageHelper.setTo(email.getEmail());//接受者
16. messageHelper.setFrom("[email protected]");//发送者
17. messageHelper.setSubject("测试邮件");//主题
18. //邮件内容，注意加参数true
19. messageHelper.setText("<html><head></head><body><h1>hello!!chao.wang</h1></body></html>",true);
20. //附件内容
21. messageHelper.addInline("a", new File("E:/xiezi.jpg"));
22. messageHelper.addInline("b", new File("E:/logo.png"));
23. File file=new File("E:/测试中文文件.rar");
24. // 这里的方法调用和插入图片是不同的，使用MimeUtility.encodeWord()来解决附件名称的中文问题
25. messageHelper.addAttachment(MimeUtility.encodeWord(file.getName()), file);
26. sender.send(mailMessage);
27. } catch (Exception e) {
28. e.printStackTrace();
29. }
30. }
