# spring boot发送邮件
[TOC]
## 一.简单文本邮件
### 1.引入相关jar包
```xml
org.springframework.boot
spring-boot-starter-web
org.springframework.boot
spring-boot-starter-mail
org.springframework.boot
spring-boot-starter-test
test
```
### 2.配置邮箱参数
在项目的**application.properties**配置文件中配置邮箱信息
```properties
# 配置邮箱信息
spring.mail.host=smtp.qq.com
spring.mail.username=1260580035@qq.com
# 配置的是授权码，不是登录密码
spring.mail.password=nejvdivlanmobaef
spring.mail.default-encoding=utf-8
```
### 3.封装SimpleMailMessage
```java
@Service
public class MailService {
@Value("${spring.mail.username}")
private String from;
public void sayHello() {
System.out.println("Hello World!");
}
/**
* 发送简单邮件
* @param to 接收人邮箱地址
* @param subject 邮件主题
* @param context 邮件内容
*/
public void sendSimpleMail(String to, String subject, String context) {
SimpleMailMessage simpleMailMessage = new SimpleMailMessage();
simpleMailMessage.setTo(to);
simpleMailMessage.setSubject(subject);
simpleMailMessage.setText(context);
simpleMailMessage.setFrom(from);
}
}
```
### 4.JavaMailSender进行发送
```java
@Service
public class MailService {
@Value("${spring.mail.username}")
private String from;
/**
* 邮件发送类
*/
@Resource
private JavaMailSender javaMailSender;
public void sayHello() {
System.out.println("Hello World!");
}
/**
* 发送简单邮件
* @param to 接收人邮箱地址
* @param subject 邮件主题
* @param context 邮件内容
*/
public void sendSimpleMail(String to, String subject, String context) {
SimpleMailMessage simpleMailMessage = new SimpleMailMessage();
simpleMailMessage.setTo(to);
simpleMailMessage.setSubject(subject);
simpleMailMessage.setText(context);
simpleMailMessage.setFrom(from);
//发送邮件
javaMailSender.send(simpleMailMessage);
}
}
```
### 5.简单邮件发送测试
```java
@SpringBootTest
class MailServiceTest {
@Resource
MailService mailService;
@Test
void sayHello() {
mailService.sayHello();
}
@Test
void sendSimpleMail() {
mailService.sendSimpleMail("1260580035@qq.com", "这个我的第一份邮件",
"大家好啊，这个邮箱内容，好好加油哦!");
}
}
```
发送成功，打开邮箱查看
## 二.发送HTML邮件
> 编写`sendHtmlMail`方法
```java
/**
* 发送HTML邮件
* @param to 接收人邮箱地址
* @param subject 邮件主题
* @param context 邮件内容
*/
public void sendHtmlMail(String to, String subject, String context) throws MessagingException {
MimeMessage message = mailSender.createMimeMessage();
MimeMessageHelper helper = new MimeMessageHelper(message, true);
helper.setFrom(from);
helper.setTo(to);
helper.setSubject(subject);
helper.setText(context, true);
mailSender.send(message);
}
```
> 编写测试方法
```java
@Test
void sendHtmlMail() throws MessagingException {
String content = "\n" +
"\n" +
"这是一份html邮件
\n" +
"百度一下\n" +
"\n" +
"";
mailService.sendHtmlMail("1260580035@qq.com", "这是一份html邮件", content);
}
```
发送成功，邮箱查看结果如下
## 三.发送带有附件邮件
> 编写**sendAttachmentsMail**方法
```java
/**
* 发送附件邮件
* @param to 接收人邮箱地址
* @param subject 邮件主题
* @param context 邮件内容
* @param filePath 附件文件路径
*/
public void sendAttachmentsMail(String to, String subject, String context, String filePath) throws MessagingException {
MimeMessage message = mailSender.createMimeMessage();
MimeMessageHelper helper = new MimeMessageHelper(message, true);
helper.setFrom(from);
helper.setTo(to);
helper.setSubject(subject);
helper.setText(context);
/*
给发送邮件添加附件
*/
FileSystemResource file = new FileSystemResource(new File(filePath));
String filename = file.getFilename();
helper.addAttachment(filename, file);
//helper.addAttachment(filename, file); //如需添加多个附件，可以多次调用addAttachment()
mailSender.send(message);
}
```
> 编写测试方法
```java
@Test
void sendAttachmentsMail() throws MessagingException {
String filePath = "D:\\01.jpg";
mailService.sendAttachmentsMail("1260580035@qq.com", "这个一封带附件的邮件",
"这是内容，带有附件", filePath);
}
```
发送成功，查看邮箱如下，带有附件
## 四.发送内嵌资源（图片）邮件
> 编写**`sendInlineMail`**方法
```java
/**
* 发送资源邮件
* @param to 接收人邮箱地址
* @param subject 邮件主题
* @param context 邮件内容
* @param rscPath 资源路径
* @param rscId 资源id
* @throws MessagingException
*/
public void sendInlineMail(String to, String subject, String context, String rscPath, String rscId) throws MessagingException {
MimeMessage message = mailSender.createMimeMessage();
MimeMessageHelper helper = new MimeMessageHelper(message, true);
helper.setFrom(from);
helper.setTo(to);
helper.setSubject(subject);
helper.setText(context, true);
/*
给发送邮件添加资源
*/
FileSystemResource res = new FileSystemResource(new File(rscPath));
helper.addInline(rscId, res);
mailSender.send(message);
}
```
> 编写测试方法
```
@Test
void sendInlineMail() throws MessagingException {
String rscPath = "D:\\01.jpg";
String rscId = "img001";
String content = "![](\'cid:")
" + "";
mailService.sendInlineMail("1260580035@qq.com", "这个一封带资源的邮件",
content, rscPath, rscId);
}
```
发送成功，查看结果如下
**如果是qq邮箱，图片显示不出来，操作如下：
1，标记邮件为未读
2，点击邮箱首页，打开未读邮件
3，点击全文，即可查看
4，查看图片
## 五.邮件模板
### 1，引入模板jar包
在pom.xml文件中引入依赖包
```xml
org.springframework.boot
spring-boot-starter-thymeleaf
```
### 2，配置html模板
在资源目录下templates下新建邮件模板emailTemplate.html文件
```html
邮件模板
这是一封注册验证邮件，请点击下面的链接完成注册，感谢您的支持！
激活账号
```
### 3，编写测试方法
```java
/**
* 注入邮件模板引擎
*/
@Resource
TemplateEngine templateEngine;
/**
* 模板邮件测试
* @throws MessagingException
*/
@Test
void sendTemplateMail() throws MessagingException {
Context context = new Context();
//属性id对应邮件模板中的属性
context.setVariable("id", "006");
String emailContext = templateEngine.process("emailTemplate", context);
mailService.sendHtmlMail("1260580035@qq.com", "这个一封模板邮件", emailContext);
}
```
查看邮箱，
点击激活账号链接，跳转页面，可以看到id属性值已经传过来了
