### 回答1:
使用Spring Boot发送电子邮件的实例代码如下:1、首先添加Maven依赖:<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-mail</artifactId>
</dependency>2、 在application.properties配置文件中添加如下配置:spring.mail.host=smtp.example.com
spring.mail.username=username
spring.mail.password=password3、编写发送邮件的类:@Component
public class MailService
{
@Autowired
private JavaMailSender mailSender; public void sendMail(String to,String subject,String content){
SimpleMailMessage message = new SimpleMailMessage();
message.setTo(to);
message.setSubject(subject);
message.setText(content);
mailSender.send(message);
}
}4、编写发送邮件的Controller:@Controller
public class MailController
{
@Autowired
private MailService mailService; @RequestMapping("sendmail")
public void sendMail(String to,String subject,String content){
mailService.sendMail(to,subject,content);
}
}

在Spring Boot中发送邮件可以借助JavaMailSender的实现类JavaMailSenderImpl,下面是一个完整的发送邮件的示例代码:
```java
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.stereotype.Component;
@Component
public class EmailSender {
@Autowired
private JavaMailSender javaMailSender;
public void sendEmail(String to, String subject, String text) {
SimpleMailMessage message = new SimpleMailMessage();
// 设置邮件接收人
message.setTo(to);
// 设置邮件主题
message.setSubject(subject);
// 设置邮件内容
message.setText(text);
// 发送邮件
javaMailSender.send(message);
}
}
```
在Spring Boot中,我们需要在application.properties或application.yml文件中配置发送邮件所需的SMTP服务器信息,如下所示:
application.properties配置文件:
```properties
spring.mail.host=smtp.example.com
spring.mail.port=587
spring.mail.username=your-email@example.com
spring.mail.password=your-password
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.smtp.starttls.enable=true
```
application.yml配置文件:
```yaml
spring:
mail:
host: smtp.example.com
port: 587
username: your-email@example.com
password: your-password
properties:
mail:
smtp:
auth: true
starttls.enable: true
```
然后,我们就可以在其他类中注入EmailSender的实例,并使用sendEmail方法发送邮件,如下所示:
```java
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
@Controller
public class HomeController {
@Autowired
private EmailSender emailSender;
@GetMapping("/")
public String home() {
String to = "recipient@example.com";
String subject = "Hello";
String text = "This is a test email.";
emailSender.sendEmail(to, subject, text);
return "home";
}
}
```
以上就是一个完整的Spring Boot中发送邮件的代码示例。通过配置邮件服务器信息,并借助JavaMailSender的实现类JavaMailSenderImpl,我们可以方便地在Spring Boot应用程序中发送邮件。

在Spring Boot中发送邮件需要引入JavaMailSender依赖。以下是一个使用Spring Boot发送邮件的示例代码。
首先,在pom.xml文件中添加以下依赖:
```xml
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-mail</artifactId>
</dependency>
```
然后,在application.properties文件中配置SMTP服务器的信息,例如:
```properties
spring.mail.host=smtp.example.com
spring.mail.port=587
spring.mail.username=your-email@example.com
spring.mail.password=your-email-password
spring.mail.properties.mail.transport.protocol=smtp
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.smtp.starttls.enable=true
```
最后,编写一个邮件发送服务类(EmailService):
```java
@Service
public class EmailService {
@Autowired
private JavaMailSender javaMailSender;
public void sendEmail(String to, String subject, String content) {
SimpleMailMessage message = new SimpleMailMessage();
message.setTo(to);
message.setSubject(subject);
message.setText(content);
javaMailSender.send(message);
}
}
```
在需要发送邮件的地方,可以通过@Autowired注入EmailService,并调用sendEmail方法来发送邮件:
```java
@RestController
public class MyController {
@Autowired
private EmailService emailService;
@GetMapping("/send-email")
public String sendEmail() {
emailService.sendEmail("recipient@example.com", "Test Subject", "Test content");
return "Email sent";
}
}
```
以上就是使用Spring Boot发送邮件的完整代码示例。需要注意的是,具体的SMTP服务器配置和邮件内容可以根据实际情况进行修改。
