Spring基於javax.mail封裝了一套用於發送電子郵件的API，位於org.springframework.mail包下，下麵將介紹下發送普通文本郵件和基於thymeleaf模版的郵件。
普通郵件
導入javax.mail依賴
<!-- ...... -->
<!-- 省略Spring依賴 -->
<dependency>
<groupId>com.sun.mail</groupId>
<artifactId>javax.mail</artifactId>
<version>1.6.2</version>
</dependency>Spring配置類
@PropertySource(value="classpath:mail.properties")
@Configuration
public class SpringConfig {
@Autowired
Environment environment;
/**
* Spring郵件配置
*/
@Bean
public JavaMailSenderImpl javaMailSenderImpl(){
JavaMailSenderImpl javaMailSenderImpl = new JavaMailSenderImpl();
javaMailSenderImpl.setHost(environment.getProperty("mail.host"));
javaMailSenderImpl.setUsername(environment.getProperty("mail.username"));
javaMailSenderImpl.setPassword(environment.getProperty("mail.password"));
javaMailSenderImpl.setDefaultEncoding(environment.getProperty("mail.encoding"));
return javaMailSenderImpl;
}
}郵件配置：mail.properties
#QQ郵箱發送郵件伺服器
mail.host=smtp.qq.com
#QQ郵箱賬戶名
[email protected]
#QQ郵箱授權碼，開啟IMAP/SMTP服務時會生成
mail.password=lrorsapyffcwbegg
#郵件發送編碼
mail.encoding=UTF-8測試
@RunWith(SpringRunner.class)
@ContextConfiguration(classes=SpringConfig.class)
public class MailTest {
@Autowired
private JavaMailSenderImpl javaMailSenderImpl;
@Test
public void testSimpleMail() throws MessagingException{
MimeMessage message = javaMailSenderImpl.createMimeMessage();
//發送帶附件和內聯元素的郵件需要將第二個參數設置為true
MimeMessageHelper helper = new MimeMessageHelper(message, true);
//發送方郵箱，和配置文件中的mail.username要一致
helper.setFrom("[email protected]");
//接收方
helper.setTo("[email protected]");
//主題
helper.setSubject("郵件測試");
//郵件內容
helper.setText("<html><body><img src='cid:myphoto'></body></html>", true);
//郵件內容內嵌的圖片,addInline中的contentId要和郵件內容中的cid相對應
FileSystemResource res = new FileSystemResource(new File("e:/yc/1.jpg"));
helper.addInline("myphoto", res);
//郵件附件
FileSystemResource file = new FileSystemResource(new File("e:/yc/myphoto.zip"));
helper.addAttachment("myphoto.zip", file);
javaMailSenderImpl.send(message);
}
}
基於thymeleaf模版的郵件
導入thymeleaf-spring依賴
<dependency>
<groupId>org.thymeleaf</groupId>
<artifactId>thymeleaf-spring4</artifactId>
<version>3.0.11.RELEASE</version>
</dependency>Spring配置類中添加thymeleaf模板配置
@Bean
public TemplateEngine emailTemplateEngine() {
SpringTemplateEngine templateEngine = new SpringTemplateEngine();
ClassLoaderTemplateResolver templateResolver = new ClassLoaderTemplateResolver();
templateResolver.setResolvablePatterns(Collections.singleton("*.html"));
templateResolver.setPrefix("/templates/");
templateResolver.setSuffix(".html");
templateResolver.setTemplateMode(TemplateMode.HTML);
templateResolver.setCharacterEncoding("UTF-8");
templateResolver.setCacheable(false);
templateEngine.addTemplateResolver(templateResolver);
return templateEngine;
}模版文件：/src/main/resources/templates/msg.html
<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<style type="text/css">span{color:orange}</style>

@Autowired
private TemplateEngine emailTemplateEngine;
@Test
public void testTemplateMail() throws MessagingException{
MimeMessage message = javaMailSenderImpl.createMimeMessage();
MimeMessageHelper helper = new MimeMessageHelper(message, true);
helper.setFrom("[email protected]");
helper.setTo("[email protected]");
helper.setSubject("郵件測試");
//thymeleaf模版解析成String
Context ctx = new Context();
ctx.setVariable("name", "小姐姐");
ctx.setVariable("validCode", "88888888");
String htmlContent = emailTemplateEngine.process("msg.html", ctx);
helper.setText(htmlContent, true);
javaMailSenderImpl.send(message);
}
