這篇文章主要為大家詳細介紹了如何利用springboot實現(xiàn)郵箱發(fā)送(激活碼)功能,文中的示例代碼簡潔易懂,有需要的小伙伴可以跟隨小編一起學(xué)習(xí)一下

第一步：現(xiàn)在郵箱里面開啟smtp服務(wù)

這里用163郵箱舉例，配置一下授權(quán)密碼，這個要提前記住

第二步：引入依賴

                </executions>
            </plugin>
        </plugins>
    </build>
 
</project>

第三步：寫配置文件

spring:
  mail:
    host: smtp.163.com # 網(wǎng)站發(fā)送郵件郵箱服務(wù) host
    port: 465
    username:  # 開啟那個服務(wù)的郵箱
    password:  # 開啟服務(wù)的那個認證碼
    properties:
      mail:
        smtp:
          auth: true
          socketFactory:
            class: javax.net.ssl.SSLSocketFactory
          starttls:
            enable: true

第四步：寫代碼

Order實體類：

package com.example.malisend.demos;
 
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
 
@Data
@AllArgsConstructor
@NoArgsConstructor
public class Order {
    private int oid;
    private String oname;
    private float price;
}

OrderManager接口

package com.example.malisend.demos;
 
public interface OrderManager {
 
    void placeOrder(Order order);
 
}

SimpleOrderManager類

package com.example.malisend.demos;
 
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
 
import javax.mail.internet.MimeMessage;
import org.springframework.mail.MailException;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.JavaMailSenderImpl;
import org.springframework.mail.javamail.MimeMessagePreparator;
import org.springframework.stereotype.Service;
 
@Service
public class SimpleOrderManager implements OrderManager {
 
    private JavaMailSender mailSender;
 
    public void setMailSender(JavaMailSender mailSender) {
        this.mailSender = mailSender;
    }
 
    public void placeOrder(final Order order) {
        // Do the business calculations...
        // Call the collaborators to persist the order...
 
        MimeMessagePreparator preparator = new MimeMessagePreparator() {
            public void prepare(MimeMessage mimeMessage) throws Exception {
                mimeMessage.setRecipient(Message.RecipientType.TO,
                        new InternetAddress("要發(fā)送給那個人的郵箱"));
                mimeMessage.setFrom(new InternetAddress("開啟服務(wù)的那個郵箱"));
                mimeMessage.setText("Dear " + order.getOname() + " " +
                        order.getPrice() + ", thanks for your order. " +
                        "Your order number is "  + ".");
            }
        };
 
        try {
            this.mailSender.send(preparator);
        }
        catch (MailException ex) {
            // simply log it and go on...
            System.err.println(ex.getMessage());
        }
    }
 
}

OrderController類

package com.example.malisend.demos;
 
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.mail.javamail.JavaMailSenderImpl;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
 
@RestController
public class OrderController {
    @Autowired
    SimpleOrderManager orderManager;
 
    @Autowired
    JavaMailSenderImpl mailSender;
 
    Order order=new Order(1,"cyl",2.8f);
    @GetMapping("/sendMail")
    public void sendMail(){
 
        orderManager.setMailSender(mailSender);
        orderManager.placeOrder(order);
    }
}

訪問：http://localhost:8080/sendMail

結(jié)果：
