简介
发送邮件可以实现，注册验证，忘记密码等功能，还可以打广告，可谓很nice的功能了
使用
添加依赖
<!--mail-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-mail</artifactId>
</dependency>
配置文件
spring:
mail:
host: *** #//邮箱服务器地址
username: ***
password: ***
default-encoding: UTF-8
#以谁来发送邮件
mail.fromMail.addr: ***
封装接口
public interface EmailService {
void sendTextEmail(String to,String subject,String content);
void sendHtmlEmali(String to,String subject,String content);
void sendAttachmentsEmail(String to,String subject,String content,String filePath);
void sendStaticResourcesEmail(String to,String subject,String content,String rscPath,String rscId);
}
实现接口，这里是关键代码了
/**
* @program:hope
* @author:aodeng
* @create:2018-10-11 13:25
**/
@Service
public class EmaliServiceImpl implements EmailService {
private static final Logger log= LoggerFactory.getLogger(EmaliServiceImpl.class);
@Autowired
private JavaMailSender mailSender;
@Value("${mail.fromMail.addr}")
private String from;
/***
* 发送文本邮件
* @param to
* @param subject
* @param content
*/
@Override
public void sendTextEmail(String to, String subject, String content) {
SimpleMailMessage mailMessage=new SimpleMailMessage();
mailMessage.setFrom(from);
mailMessage.setTo(to);
mailMessage.setSubject(subject);
mailMessage.setText(content);
try {
mailSender.send(mailMessage);
log.info("[文本邮件发送成功，当前时间]-[{}]",new Date());
}catch (Exception e){
e.printStackTrace();
}
}
/***
* html邮件
* @param to
* @param subject
* @param content
*/
@Override
public void sendHtmlEmali(String to, String subject, String content) {
MimeMessage message=mailSender.createMimeMessage();
try {
MimeMessageHelper helper=new MimeMessageHelper(message,true);//true表示创建一个multipart message
helper.setFrom(from);
helper.setTo(to);
helper.setSubject(subject);
helper.setText(content);
//发送邮件
mailSender.send(message);
log.info("[html邮件发送成功，当前时间]-[{}]",new Date());
}catch (MessagingException e){
e.printStackTrace();
}
}
/***
* 附件邮件
* @param to
* @param subject
* @param content
* @param filePath
*/
@Override
public void sendAttachmentsEmail(String to, String subject, String content, String filePath) {
MimeMessage message=mailSender.createMimeMessage();
try {
MimeMessageHelper helper=new MimeMessageHelper(message,true);//true表示创建一个multipart message
helper.setFrom(from);
helper.setTo(to);
helper.setSubject(subject);
helper.setText(content,true);
//上传附件
FileSystemResource resource=new FileSystemResource(new File(filePath));
String fileName=filePath.substring(filePath.lastIndexOf(File.separator));
helper.addAttachment(fileName,resource);
//发送邮件
mailSender.send(message);
log.info("[附件邮件发送成功，当前时间]-[{}]",new Date());
}catch (MessagingException e){
e.printStackTrace();
}
}
/***
* 嵌入静态资源邮件
* @param to
* @param subject
* @param content
* @param rscPath
* @param rscId
*/
@Override
public void sendStaticResourcesEmail(String to, String subject, String content, String rscPath, String rscId) {
MimeMessage message=mailSender.createMimeMessage();
try {
MimeMessageHelper helper=new MimeMessageHelper(message,true);//true表示创建一个multipart message
helper.setFrom(from);
helper.setTo(to);
helper.setSubject(subject);
helper.setText(content,true);
//嵌入静态资源
FileSystemResource resource=new FileSystemResource(new File(rscPath));
helper.addInline(rscId,resource);
//发送邮件
mailSender.send(message);
log.info("[嵌入静态资源邮件发送成功，当前时间]-[{}]",new Date());
}catch (MessagingException e){
e.printStackTrace();
}
}
}
测试功能
@Test
public void test1(){
//for(int i=0;i<=2;i++){
emailService.sendTextEmail("邮件地址","测试","收到请回复，over！");
//}
}
@Test
public void test2(){
String content="<html>\n" +
"<body>\n" +
" <h3>hello world ! 这是一封html邮件!</h3>\n" +
"</body>\n" +
"</html>";
emailService.sendHtmlEmali("邮件地址","测试",content);
}
@Test
public void test3(){
emailService.sendAttachmentsEmail("邮件地址","测试","收到请回复，over！","C:\\Users\\ad182\\Pictures\\image3\\a.jpg");
}
@Test
public void test4(){
String rscId = "neo006";
String content="<html><body>这是有图片的邮件：<img src=\'cid:" + rscId + "\' ></body></html>";
String imgPath = "C:\\Users\\ad182\\Pictures\\image3\\a.jpg";
emailService.sendStaticResourcesEmail("邮件地址","测试",content,imgPath,rscId);
}
还有一个发送邮件验证的功能
添加引擎模板
<!-- 模板引擎 -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
创建一个页面，注意：页面名称和后台参数名称要一致
<body>
您好,这是验证邮件,请点击下面的链接完成验证,<br/>
<a href="#" th:href="@{ https://aodeng.cc/{id}(id=${id}) }">激活账号</a>
</body>
发送验证邮件，其实就是后台拼接一个参数到页面，将页面发个用户，用户点击页面的带参数的链接，后台接收参数，然后就实现验证的功能了
@Test
public void test5() {
//创建邮件正文
org.thymeleaf.context.Context context = new org.thymeleaf.context.Context();
context.setVariable("id", "006");
String emailContent = templateEngine.process("emailTemplate", context);
emailService.sendHtmlEmali("f12974049826@163.com","主题：这是模板邮件",emailContent);
}
