SpingBoot环境下发送邮件

眰恦 2022/05/31 18:30:51 206 1 2

简介:Spring框架通过使用JavaMailSender接口为发送电子邮件提供了一个抽象，Spring Boot为它提供了自动配置以及一个启动模块。其不同的属性配置可以查看MailProperties来解决。

### 一、开启邮箱授权码和SMTP服务
**新浪邮箱：**
![](/upload/images/20220531/5cf950ec-b4d9-4f8a-8b67-5a2b63a71579.png)

**QQ邮箱：**
![](/upload/images/20220531/68eea2c8-3a92-467c-8bb1-7dc114ca4e96.png)

### 二、导入依赖

**pom.xml**
```xml
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-mail</artifactId>
    <version>2.2.0.RELEASE</version>
</dependency>
```
### 三、配置邮件参数

**application.yml**
```xml
spring:
  mail:
    host: smtp.sina.com		#新浪邮箱服务器
    #host: smtp.qq.com		#QQ邮箱服务器
    port: 465
    username: itkongdongyang@sina.com		#新浪邮箱账号
    #username: 707484721@qq.com		#QQ邮箱账号
    password: fda**********ada		#新浪邮箱授权码
    #password: zqs**********bbd		#QQ邮箱授权码
    protocol: smtps
    properties:
      mail:
        smtp:
          ssl:
            enable: true
          starttls:
            enable: true
            required: true
        stml:
          auth: true
```

### 四、编写发送邮件工具类
```java
package cn.dongyangjun.config;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.MimeMessageHelper;
import org.springframework.stereotype.Component;

import javax.mail.MessagingException;
import javax.mail.internet.MimeMessage;

@Component
public class MailClient {

private static final Logger logger = LoggerFactory.getLogger(MailClient.class);

@Autowired
    private JavaMailSender mailSender;

@Value("${spring.mail.username}")
    private String from;

public void sendMail(String to, String subject, String content) {
        try {
            MimeMessage message = mailSender.createMimeMessage();
            MimeMessageHelper helper = new MimeMessageHelper(message);
            helper.setFrom(from);
            helper.setTo(to);
            helper.setSubject(subject);
            helper.setText(content, true);
            mailSender.send(helper.getMimeMessage());
        } catch (MessagingException e) {
            logger.error("发送邮件失败:" + e.getMessage());
        }
    }

}
```

### 五、发送邮件
```java
package cn.dongyangjun.test;

import cn.dongyangjun.Application;
import cn.dongyangjun.config.MailClient;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringRunner;

@RunWith(SpringRunner.class)
@SpringBootTest
@ContextConfiguration(classes = Application.class)
public class MailTests {

@Autowired
    private MailClient mailClient;

@Test
    public void testTextMail() {
        mailClient.sendMail("目标邮箱", "邮件标题", "邮件内容");
    }
}
```
