spring boot 发送邮件

2016-07-05 17:49 465 查看

简单几步，实现在spring boot中发送邮件：

1、引入依赖：

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-mail</artifactId>
</dependency>

2、application.yml中配置邮件相关的参数：

spring:
mail:
host: smtp.exmail.qq.com
username: 用户名
password: 密码
properties:
mail:
smtp:
auth: true
starttls:
enable: true
required: true

3、邮件service代码：

@Service
public class MailService {
private final Logger logger = LoggerFactory.getLogger(this.getClass());

@Autowired
private JavaMailSender sender;

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

/**
* 发送纯文本的简单邮件
* @param to
* @param subject
* @param content
*/
public void sendSimpleMail(String to, String subject, String content){
SimpleMailMessage message = new SimpleMailMessage();
message.setFrom(from);
message.setTo(to);
message.setSubject(subject);
message.setText(content);

try {
sender.send(message);
logger.info("简单邮件已经发送。");
} catch (Exception e) {
logger.error("发送简单邮件时发生异常！", e);
}
}

/**
* 发送html格式的邮件
* @param to
* @param subject
* @param content
*/
public void sendHtmlMail(String to, String subject, String content){
MimeMessage message = sender.createMimeMessage();

try {
//true表示需要创建一个multipart message
MimeMessageHelper helper = new MimeMessageHelper(message, true);
helper.setFrom(from);
helper.setTo(to);
helper.setSubject(subject);
helper.setText(content, true);

sender.send(message);
logger.info("html邮件已经发送。");
} catch (MessagingException e) {
logger.error("发送html邮件时发生异常！", e);
}
}

/**
* 发送带附件的邮件
* @param to
* @param subject
* @param content
* @param filePath
*/
public void sendAttachmentsMail(String to, String subject, String content, String filePath){
MimeMessage message = sender.createMimeMessage();

try {
//true表示需要创建一个multipart message
MimeMessageHelper helper = new MimeMessageHelper(message, true);
helper.setFrom(from);
helper.setTo(to);
helper.setSubject(subject);
helper.setText(content, true);

FileSystemResource file = new FileSystemResource(new File(filePath));
String fileName = filePath.substring(filePath.lastIndexOf(File.separator));
helper.addAttachment(fileName, file);

sender.send(message);
logger.info("带附件的邮件已经发送。");
} catch (MessagingException e) {
logger.error("发送带附件的邮件时发生异常！", e);
}
}

/**
* 发送嵌入静态资源（一般是图片）的邮件
* @param to
* @param subject
* @param content 邮件内容，需要包括一个静态资源的id，比如：<img src=\"cid:rscId01\" >
* @param rscPath 静态资源路径和文件名
* @param rscId 静态资源id
*/
public void sendInlineResourceMail(String to, String subject, String content, String rscPath, String rscId){
MimeMessage message = sender.createMimeMessage();

try {
//true表示需要创建一个multipart message
MimeMessageHelper helper = new MimeMessageHelper(message, true);
helper.setFrom(from);
helper.setTo(to);
helper.setSubject(subject);
helper.setText(content, true);

FileSystemResource res = new FileSystemResource(new File(rscPath));
helper.addInline(rscId, res);

sender.send(message);
logger.info("嵌入静态资源的邮件已经发送。");
} catch (MessagingException e) {
logger.error("发送嵌入静态资源的邮件时发生异常！", e);
}
}
}

4、单元测试代码：

public class MailTests extends BasicUtClass{
@Autowired
private MailService mailService;

private String to = "xujijun@mail.cn";

@Test
public void sendSimpleMail() {
mailService.sendSimpleMail(to, "主题：简单邮件", "测试邮件内容");
}

@Autowired
VelocityEngine velocityEngine;

@Test
public void sendHtmlMail() {
Map<String, Object> model = new HashMap<String, Object>();
model.put("time", XDateUtils.nowToString());
model.put("message", "这是测试的内容。。。");
model.put("toUserName", "张三");
model.put("fromUserName", "老许");
String content = VelocityEngineUtils.mergeTemplateIntoString(velocityEngine, "welcome.vm", "UTF-8", model);

mailService.sendHtmlMail(to, "主题：html邮件", content);
}

@Test
public void sendAttachmentsMail() {
mailService.sendAttachmentsMail(to, "主题：带附件的邮件", "有附件，请查收！", "C:\\Users\\Xu\\Desktop\\csdn\\1.png");
}

@Test
public void sendInlineResourceMail() {
String rscId = "rscId001";
mailService.sendInlineResourceMail(to,
"主题：嵌入静态资源的邮件",
"<html><body>这是有嵌入静态资源：<img src=\'cid:" + rscId + "\' ></body></html>",
"C:\\Users\\Xu\\Desktop\\csdn\\1.png",
rscId);
}
}
