一、简介
要在网络上实现邮件功能，必须要有专门的邮件服务器。这些邮件服务器类似于现实生活中的邮局，它主要负责接收用户投递过来的邮件，并把邮件投递到邮件接收者的电子邮箱中。
SMTP服务器地址：
一般是 smtp.xxx.com，比如163邮箱是smtp.163.com，qq邮箱是smtp.qq.com。
SMTP协议：
通常把处理用户smtp请求(邮件发送请求)的服务器称之为SMTP服务器(邮件发送服务器)。
POP3协议：
通常把处理用户pop3请求(邮件接收请求)的服务器称之为POP3服务器(邮件接收服务器)。
二、邮箱服务授权配置
163邮箱在：设置—POP3中，打开相应的配置属性；
QQ邮箱：设置—账户安全中，打开相应的配置信息；
二、pom.xml依赖
<!--邮件服务-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-mail</artifactId>
</dependency>
<dependency>
<groupId>commons-net</groupId>
<artifactId>commons-net</artifactId>
<version>3.3</version>
</dependency>
三、properties配置文件
#邮箱的账号(163邮箱)
spring.mail.host= smtp.163.com
spring.mail.username=comlydms@163.com
spring.mail.password=158143484fs
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.starttls.enable=true
spring.mail.properties.mail.starttls.required=true
四、发送普通邮件
1、web层代码
@RequestMapping(value = "/simpleEmail", method = {RequestMethod.POST})
public ApiResult sendSimpleEmail() {
mailService.sendSimpleMail("395096666@qq.com", "这是一个测试邮件", "这是一个测试邮件");
return ApiResult.succ("调用成功");
}
2、Service代码
private final Logger logger = LoggerFactory.getLogger(this.getClass());
@Autowired
private JavaMailSender sender;
@Value("${spring.mail.username}")
private String fromMail;
public void sendSimpleMail(String toMail, String subject, String content) {
SimpleMailMessage simpleMailMessage = new SimpleMailMessage();
simpleMailMessage.setFrom(fromMail);
simpleMailMessage.setTo(toMail);
simpleMailMessage.setSubject(subject);
simpleMailMessage.setText(content);
try {
sender.send(simpleMailMessage);
logger.info("发送给:{}简单邮件已经发送。 subject:{}", toMail, subject);
} catch (Exception e) {
logger.info("发送给:{}send mail error subject:{}", toMail, subject);
e.printStackTrace();
}
}
二、发送Html格式邮件
1、Web层代码
@RequestMapping(value = "/htmlEmail", method = {RequestMethod.POST})
public ApiResult sendHtmlEmail() {
English english = new English();
english.setEnglish("my");
english.setChinese("我的");
english.setCodechinese("自己的东西");
ArrayList<English> en = new ArrayList<>();
en.add(english);
en.add(english);
String start = "<!DOCTYPE html><html><head><meta charset=\"utf-8\"><title></title></head><body><font color=\"red\">定时发送</font><table border=\"1\"><tr><th>英文</th><th>标准注解</th><th>代码中注解</th></tr>";
String prime = "";
for (int i = 0; i < en.size(); i++) {
English english1 = en.get(i);
String center = "<tr><td>English</td><td>Chinese</td><td>CodeChinese</td></tr>";
String one = center.replaceFirst("English", english1.getEnglish());
String two = one.replaceFirst("Chinese", english1.getChinese());
String result = two.replaceFirst("CodeChinese", english1.getCodechinese());
prime = prime + result;
}
String end = "</table></body></html>";
String html = start + prime + end;
mailService.sendHtmlMail("395096666@qq.com", "定时邮件发送", html);
return ApiResult.succ("调用成功");
}
2、Service代码
private final Logger logger = LoggerFactory.getLogger(this.getClass());
@Autowired
private JavaMailSender sender;
@Value("${spring.mail.username}")
private String fromMail;
public void sendHtmlMail(String toMail, String subject, String content) {
MimeMessage mimeMessage = sender.createMimeMessage();
try {
MimeMessageHelper mimeMessageHelper = new MimeMessageHelper(mimeMessage, true);
mimeMessageHelper.setTo(toMail);
mimeMessageHelper.setFrom(fromMail);
mimeMessageHelper.setText(content, true);
mimeMessageHelper.setSubject(subject);
sender.send(mimeMessage);
logger.info("发送给:{}html邮件已经发送。 subject:{}", toMail, subject);
} catch (Exception e) {
logger.info("发送给:{}html send mail error subject:{}", toMail, subject);
e.printStackTrace();
}
}
三、发送Html带图片邮件
1、Web层代码
@RequestMapping(value = "/htmlPotoEmail", method = {RequestMethod.POST})
public ApiResult sendHtmlPoto() {
String html = "<!DOCTYPE html>\r\n" +
"<html>\r\n" +
"<head>\r\n" +
"<meta charset=\"UTF-8\">\r\n" +
"<title>Insert title here</title>" +
"\r\n" +
"</head>\r\n" +
"<body>\r\n" +
"<img src=\"cid:image1\"/> " +
"<img src=\"cid:image2\"/> " +
" <font color=\"red\">发送html</font>\r\n" +
"</body>\r\n" +
"</html>";
List<InlineResource> list = new ArrayList<>();
String path = WordSmsController.class.getClassLoader().getResource("image.jpg").getPath();
InlineResource resource = new InlineResource("image1", path);
InlineResource resource2 = new InlineResource("image2", path);
list.add(resource2);
list.add(resource);
mailService.sendHtmlPhotoMail("395096666@qq.com", "这是一个测试邮件", html, list);
return ApiResult.succ("调用成功");
}
2、Service层代码
private final Logger logger = LoggerFactory.getLogger(this.getClass());
@Autowired
private JavaMailSender sender;
@Value("${spring.mail.username}")
private String fromMail;
public void sendHtmlPhotoMail(String to, String subject, String content, List<InlineResource> resourceist) {
MimeMessage me
