一、SMTP协议发送邮件
老规矩，先贴代码
1.一个工具类
import com.sun.mail.util.MailSSLSocketFactory;
import org.springframework.stereotype.Component;
import javax.mail.*;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeBodyPart;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeMultipart;
import java.io.IOException;
import java.io.UnsupportedEncodingException;
import java.security.GeneralSecurityException;
import java.util.Date;
import java.util.Properties;
@Component
public class SendEmailUtil {
private static String account = "登录用户名";//登录用户名
private static String pass = "登录密码"; //登录密码
private static String host = "smtp.exmail.qq.com"; //服务器地址（邮件服务器）
private static String port = "465"; //端口
private static String protocol = "smtp"; //协议
static class MyAuthenricator extends Authenticator {
String u;
String p;
public MyAuthenricator(String u,String p){
this.u=u;
this.p=p;
}
@Override
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(u,p);
}
}
public void send(String to, String subject, String content){
Properties prop = new Properties();
//协议
prop.setProperty("mail.transport.protocol", protocol);
//服务器
prop.setProperty("mail.smtp.host", host);
//端口
prop.setProperty("mail.smtp.port", port);
//使用smtp身份验证
prop.setProperty("mail.smtp.auth", "true");
//使用SSL，企业邮箱必需！
//开启安全协议
MailSSLSocketFactory sf = null;
try {
sf = new MailSSLSocketFactory();
sf.setTrustAllHosts(true);
} catch (GeneralSecurityException e1) {
e1.printStackTrace();
}
prop.put("mail.smtp.ssl.enable", "true");
prop.put("mail.smtp.ssl.socketFactory", sf);
Session session = Session.getDefaultInstance(prop, new MyAuthenricator(account, pass));
session.setDebug(true);
MimeMessage mimeMessage = new MimeMessage(session);
try {
//发件人
mimeMessage.setFrom(new InternetAddress(account,"XXX")); //可以设置发件人的别名
//mimeMessage.setFrom(new InternetAddress(account)); //如果不需要就省略
//收件人
mimeMessage.addRecipient(Message.RecipientType.TO, new InternetAddress(to));
//主题
mimeMessage.setSubject(subject);
//时间
mimeMessage.setSentDate(new Date());
//容器类，可以包含多个MimeBodyPart对象
Multipart mp = new MimeMultipart();
//MimeBodyPart可以包装文本，图片，附件
MimeBodyPart body = new MimeBodyPart();
//HTML正文
body.setContent(content, "text/html; charset=UTF-8");
mp.addBodyPart(body);
//设置邮件内容
mimeMessage.setContent(mp);
//仅仅发送文本
//mimeMessage.setText(content);
mimeMessage.saveChanges();
Transport.send(mimeMessage);
} catch (MessagingException e) {
e.printStackTrace();
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
}
这里面主要配置的是发件邮箱的账号，密码，还有服务器地址（邮箱服务器），我这边使用的是smtp.exmail.qq.com，还有端口号465以及邮箱协议smtp。
这些信息必须自己先登录过邮箱，验证下正确性，再填写上去测试，不然搞的一个错的账号密码，怎么可能成功。然后比如一些协议或者服务器地址不知道的话可以先用邮箱软件登录看下配置。可以用outlook，网易邮箱大师，我这边就给大家看下邮箱大师是怎么看的，如图：

我这边总共有三个邮箱，我点击查看想要配置发件箱的邮箱配置：

这里可以看到发件与收件服务器的地址以及端口号。
2.发件
写一个controller
@RestController
@RequestMapping("/email")
public class EmailController {
@Autowired
public SendEmailUtil emailUtil;
private static String to = "发件邮箱地址";
private static String subject = "测试邮件标题";
private static String text = "测试邮件内容信息";
@GetMapping(path = "sendEmail")
public Boolean sendEmail(){
log.info("Sending!");
emailUtil.send(to, subject , text );
log.info("Done!");
return Boolean.TRUE;
}
}
这里就是调用1的组件发送邮箱。下面介绍下Exchange邮箱的发件配置
二、Exchange协议发送邮件
1.maven配置
