Spring Boot如何开启一个邮件服务呢?
下文笔者讲述SpringBoot开启邮件服务,对外发送邮件的方法分享呢?下文笔者将一一道来,如下所示
邮件
邮件是我们日常工作中使用最多的一种通讯工具 那么java代码如何实现发送邮件的功能呢? 下文笔者将讲述java代码实现邮件发送的方法分享,如下所示
发送邮件的实现思路:
1.引入相应的发送邮件的starter,如：spring-boot-starter-mail
2.在application.properties上定义邮件的服务器及账户密码信息
3.编写相应的邮件service
方法中使用SimpleMailMessage对象
例:发送邮件的示例
//pom包引入相应的starter
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-mail</artifactId>
</dependency>
</dependencies>
//application.properties中添加邮箱配置
spring.mail.host=smtp.qiye.163.com //邮箱服务器地址
spring.mail.username=xxx@oo.com //用户名
spring.mail.password=xxyyooo //密码
spring.mail.default-encoding=UTF-8
mail.fromMail.addr=xxx@oo.com //以谁来发送邮件
//编写mailService 具体的实现类
@Component
public class MailServiceImpl implements MailService{
private final Logger logger = LoggerFactory.getLogger(this.getClass());
@Autowired
private JavaMailSender mailSender;
@Value("${mail.fromMail.addr}")
private String from;
@Override
public void sendSimpleMail(String to, String subject, String content) {
SimpleMailMessage message = new SimpleMailMessage();
message.setFrom(from);
message.setTo(to);
message.setSubject(subject);
message.setText(content);
try {
mailSender.send(message);
logger.info("简单邮件已经发送。");
} catch (Exception e) {
logger.error("发送简单邮件时发生异常！", e);
}
}
}
//test类进行测试
@RunWith(SpringRunner.class)
@SpringBootTest
public class MailServiceTest {
@Autowired
private MailService MailService;
@Test
public void testSimpleMail() throws Exception {
MailService.sendSimpleMail("ityouknow@126.com","test simple mail"," hello this is simple mail");
}
}
//发送html格式邮件的示例
public void sendHtmlMail(String to, String subject, String content) {
MimeMessage message = mailSender.createMimeMessage();
try {
//true表示需要创建一个multipart message
MimeMessageHelper helper = new MimeMessageHelper(message, true);
helper.setFrom(from);
helper.setTo(to);
helper.setSubject(subject);
helper.setText(content, true);
mailSender.send(message);
logger.info("html邮件发送成功");
} catch (MessagingException e) {
logger.error("发送html邮件时发生异常！", e);
}
}
//测试html邮件发送测试
@Test
public void testHtmlMail() throws Exception {
String content="<html>\n" +
"<body>\n" +
" <h3>hello java265.com ! 这是一封Html邮件!</h3>\n" +
"</body>\n" +
"</html>";
MailService.sendHtmlMail("admin@java265.com","test java html email send",content);
}
//发送带附件的邮件
//MailService中新增sendAttachmentsMail方法
public void sendAttachmentsMail(String to, String subject, String content, String filePath){
MimeMessage message = mailSender.createMimeMessage();
try {
MimeMessageHelper helper = new MimeMessageHelper(message, true);
helper.setFrom(from);
helper.setTo(to);
helper.setSubject(subject);
helper.setText(content, true);
//多次调用,则可添加多个附件
FileSystemResource file = new FileSystemResource(new File(filePath));
String fileName = filePath.substring(filePath.lastIndexOf(File.separator));
helper.addAttachment(fileName, file);
mailSender.send(message);
logger.info("带附件的邮件已经发送。");
} catch (MessagingException e) {
logger.error("发送带附件的邮件时发生异常！", e);
}
}
//测试发送带附件的邮件
@Test
public void sendAttachmentsMail() {
String filePath="d:\\test\\test.log";
mailService.sendAttachmentsMail("admin@java265.com", "主题：带附件的邮件", "有附件，请查收！", filePath);
}
//发送带静态资源的邮件
public void sendInlineResourceMail(String to, String subject, String content, String rscPath, String rscId){
MimeMessage message = mailSender.createMimeMessage();
try {
MimeMessageHelper helper = new MimeMessageHelper(message, true);
helper.setFrom(from);
helper.setTo(to);
helper.setSubject(subject);
helper.setText(content, true);
FileSystemResource res = new FileSystemResource(new File(rscPath));
helper.addInline(rscId, res);
mailSender.send(message);
logger.info("嵌入静态资源的邮件已经发送。");
} catch (MessagingException e) {
logger.error("发送嵌入静态资源的邮件时发生异常！", e);
}
}
//测试发送静态资源的方法,等同于附件发送
@Test
public void sendInlineResourceMail() {
String rscId = "neo006";
String content="<html><body>这是有图片的邮件：<img src=\'cid:" + rscId + "\' ></body></html>";
String imgPath = "D:\\test\\test.png";
mailService.sendInlineResourceMail("admin@java265.com", "主题：这是有图片的邮件", content, imgPath, rscId);
}
