Spring Boot 中可以使用 JavaMail API 来读取 IMAP 邮件。下面是一个简单的示例:
1. 添加依赖
```xml
<dependency>
<groupId>com.sun.mail</groupId>
<artifactId>javax.mail</artifactId>
<version>1.6.0</version>
</dependency>
```
2. 编写配置类
```java
@Configuration
public class MailConfig {
@Value("${spring.mail.host}")
private String host;
@Value("${spring.mail.port}")
private int port;
@Value("${spring.mail.username}")
private String username;
@Value("${spring.mail.password}")
private String password;
@Bean
public JavaMailSenderImpl javaMailSender() {
JavaMailSenderImpl mailSender = new JavaMailSenderImpl();
mailSender.setHost(host);
mailSender.setPort(port);
mailSender.setUsername(username);
mailSender.setPassword(password);
Properties properties = new Properties();
properties.setProperty("mail.store.protocol", "imaps");
mailSender.setJavaMailProperties(properties);
return mailSender;
}
@Bean
public Store store() throws Exception {
Store store = javaMailSender().getSession().getStore();
store.connect();
return store;
}
}
```
3. 编写读取邮件的代码
```java
@Service
public class MailService {
private final Store store;
@Autowired
public MailService(Store store) {
this.store = store;
}
public void readMail() throws Exception {
Folder inbox = store.getFolder("INBOX");
inbox.open(Folder.READ_ONLY);
Message[] messages = inbox.getMessages();
for (Message message : messages) {
System.out.println("Subject: " + message.getSubject());
System.out.println("From: " + message.getFrom()[0]);
System.out.println("Text: " + message.getContent().toString());
}
inbox.close(false);
}
}
```
在上面的代码中,我们从 `MailConfig` 中注入了 `Store` 实例,然后使用 `Store` 实例连接到邮件服务器,读取 INBOX 文件夹中的邮件并打印出来。
最后,我们可以在 Spring Boot 应用程序的任何位置调用 `MailService` 的 `readMail` 方法来读取邮件。
