簡介
傳送郵件可以實現，註冊驗證，忘記密碼等功能，還可以打廣告，可謂很nice的功能了
使用
新增依賴
<!--mail--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-mail</artifactId> </dependency>
配置檔案
spring: mail: host: *** #//郵箱伺服器地址 username: *** password: *** default-encoding: UTF-8 #以誰來發送郵件 mail.fromMail.addr: ***
封裝介面
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);
}
實現介面，這裡是關鍵程式碼了
/**
* @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;
/***
* 傳送文字郵件
* @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("[文字郵件傳送成功，當前時間]-[{}]",new Date());
}catch (Exception e){
e.printStackTrace();
}
}
/***
* html郵件
* @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表示建立一個multipart message
helper.setFrom(from);
helper.setTo(to);
helper.setSubject(subject);
helper.setText(content);
//傳送郵件
mailSender.send(message);
log.info("[html郵件傳送成功，當前時間]-[{}]",new Date());
}catch (MessagingException e){
e.printStackTrace();
}
}
/***
* 附件郵件
* @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表示建立一個multipart message
helper.setFrom(from);
helper.setTo(to);
helper.setSubject(subject);
helper.setText(content,true);
//上傳附件
FileSystemResource resource=new FileSystemResource(new File(filePath));
String fileName=filePath.substring(filePath.lastIndexOf(File.separator));
helper.addAttachment(fileName,resource);
//傳送郵件
mailSender.send(message);
log.info("[附件郵件傳送成功，當前時間]-[{}]",new Date());
}catch (MessagingException e){
e.printStackTrace();
}
}
/***
* 嵌入靜態資源郵件
* @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表示建立一個multipart message
helper.setFrom(from);
helper.setTo(to);
helper.setSubject(subject);
helper.setText(content,true);
//嵌入靜態資源
FileSystemResource resource=new FileSystemResource(new File(rscPath));
helper.addInline(rscId,resource);
//傳送郵件
mailSender.send(message);
log.info("[嵌入靜態資源郵件傳送成功，當前時間]-[{}]",new Date());
}catch (MessagingException e){
e.printStackTrace();
}
}
}
測試功能
@Test
public void test1(){
//for(int i=0;i<=2;i++){
emailService.sendTextEmail("郵件地址","測試","收到請回復，over！");
//}
}
@Test
public void test2(){
String content="<html>\n" +
"<body>\n" +
"<h3>hello world ! 這是一封html郵件!</h3>\n" +
"</body>\n" +
"</html>";
emailService.sendHtmlEmali("郵件地址","測試",content);
}
@Test
public void test3(){
emailService.sendAttachmentsEmail("郵件地址","測試","收到請回復，over！","C:\\Users\\ad182\\Pictures\\image3\\a.jpg");
}
@Test
public void test4(){
String rscId = "neo006";
String content="<html><body>這是有圖片的郵件：<img src=\'cid:" + rscId + "\' ></body></html>";
String imgPath = "C:\\Users\\ad182\\Pictures\\image3\\a.jpg";
emailService.sendStaticResourcesEmail("郵件地址","測試",content,imgPath,rscId);
}
還有一個傳送郵件驗證的功能
新增引擎模板
<!-- 模板引擎 --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-thymeleaf</artifactId> </dependency>
建立一個頁面，注意：頁面名稱和後臺引數名稱要一致
<body>
您好,這是驗證郵件,請點選下面的連結完成驗證,<br/>
<a href="#" th:href="@{ https://aodeng.cc/{id}(id=${id}) }">啟用賬號</a>
</body>
傳送驗證郵件，其實就是後臺拼接一個引數到頁面，將頁面發個使用者，使用者點選頁面的帶引數的連結，後臺接收引數，然後就實現驗證的功能了
@Test
public void test5() {
//建立郵件正文
org.thymeleaf.context.Context context = new org.thymeleaf.context.Context();
context.setVariable("id", "006");
String emailContent = templateEngine.process("emailTemplate", context);
emailService.sendHtmlEmali("[email protected]","主題：這是模板郵件",emailContent);
}
