sringboot+vue集成邮箱收取邮件代码

Sure! Here's an example of how you can integrate email retrieval functionality into a Spring Boot + Vue.js application:

1. Backend (Spring Boot):
First, you'll need to add the necessary dependencies to your Spring Boot project. Add the following dependencies in your `pom.xml` file:

<dependencies>
    <!-- Spring Mail -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-mail</artifactId>
    </dependency>
    
    <!-- Other dependencies -->
    ...
</dependencies>

2. Configure Email Properties:
In your `application.properties` file, configure the email properties:

# SMTP Server Configuration
spring.mail.host=your-smtp-server
spring.mail.port=your-smtp-port
spring.mail.username=your-username
spring.mail.password=your-password
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.smtp.starttls.enable=true

# IMAP Server Configuration
spring.mail.store.protocol=imaps
spring.mail.imap.host=your-imap-server
spring.mail.imap.port=your-imap-port

3. Create a Service Class:
Create a service class to handle email retrieval operations. For example, create a `EmailService` class with a method to retrieve emails:

@Service
public class EmailService {
    
    @Autowired
    private JavaMailSender javaMailSender;
    
    public List<String> getEmails() throws MessagingException {
        List<String> emails = new ArrayList<>();
        
        Properties properties = new Properties();
        properties.setProperty("mail.store.protocol", "imaps");
        
        Session session = Session.getInstance(properties);
        Store store = session.getStore();
        
        store.connect("your-imap-server", "your-username", "your-password");
        
        Folder inbox = store.getFolder("INBOX");
        inbox.open(Folder.READ_ONLY);
        
        Message[] messages = inbox.getMessages();
        
        for (Message message : messages) {
            String subject = message.getSubject();
            emails.add(subject);
        }
        
        inbox.close(false);
        store.close();
        
        return emails;
    }
}

4. Expose the Service as a REST API:
Create a controller class to expose the email retrieval functionality as a REST API. For example:

@RestController
@RequestMapping("/api/emails")
public class EmailController {
    
    @Autowired
    private EmailService emailService;
    
    @GetMapping
    public List<String> getEmails() throws MessagingException {
        return emailService.getEmails();
    }
}

5. Frontend (Vue.js):
In your Vue.js application, you can now make a request to the backend API to retrieve emails. Here's an example using Axios:

import axios from 'axios';

export default {
    data() {
        return {
            emails: []
        };
    },
    mounted() {
        this.getEmails();
    },
    methods: {
        getEmails() {
            axios.get('/api/emails')
                .then(response => {
                    this.emails = response.data;
                })
                .catch(error => {
                    console.error(error);
                });
        }
    }
};

Make sure to replace `/api/emails` with the appropriate URL of your backend API.

That's it! You now have a Spring Boot + Vue.js application that integrates email retrieval functionality.
