com.sun.mail javax.mail

1.先引入maven依赖，在pom.xml文件中添加：

 <!--        引入邮箱插件-->
        <!-- https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-mail -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-mail</artifactId>
            <version>2.1.1.RELEASE</version>
        </dependency>

注意里面我使用的是log4j日志对信息进行记录，不懂得同学们可以点击此处快速学习

2.创建javaSocket类

import com.sun.mail.util.MailSSLSocketFactory;
import com.talent.api.commonApi.ContenConfig;

import javax.mail.*;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import java.util.Properties;

public class JavaSocket {
    private static final String EMAIL_SEND = "自己的邮箱";
    private static final String EMAIL_KEY = "16位的授权码";
    public static void sendEmail(EmailModel emailModel) throws Exception {


        Properties prop = new Properties();
        prop.setProperty("mail.host", "smtp.qq.com");
//        设置QQ邮件服务器
        prop.setProperty("mail.transport.protocol", "smtp"); // 邮件发送协议
        prop.setProperty("mail.smtp.auth", "true"); // 需要验证用户名密码

        // 关于QQ邮箱，还要设置SSL加密，加上以下代码即可
        MailSSLSocketFactory sf = new MailSSLSocketFactory();
        sf.setTrustAllHosts(true);
        prop.put("mail.smtp.ssl.enable", "true");
        prop.put("mail.smtp.ssl.socketFactory", sf);


        //使用JavaMail发送邮件的5个步骤

        //创建定义整个应用程序所需的环境信息的 Session 对象

        Session session = Session.getDefaultInstance(prop, new Authenticator() {
            public PasswordAuthentication getPasswordAuthentication() {
                //发件人邮件用户名、授权码
                return new PasswordAuthentication(EMAIL_SEND, EMAIL_KEY);
            }
        });

        //开启Session的debug模式，这样就可以查看到程序发送Email的运行状态
        session.setDebug(true);

        //2、通过session得到transport对象
        Transport ts = session.getTransport();

        //3、使用邮箱的用户名和授权码连上邮件服务器
        ts.connect("smtp.qq.com", EMAIL_SEND, EMAIL_KEY);

        //4、创建邮件

        //创建邮件对象
        MimeMessage message = new MimeMessage(session);

        //指明邮件的发件人
        message.setFrom(new InternetAddress(EMAIL_SEND));

        //指明邮件的收件人，现在发件人和收件人是一样的，那就是自己给自己发
        message.setRecipient(Message.RecipientType.TO, new InternetAddress(emailModel.getEmailReciver()));

        //邮件的标题
        message.setSubject(emailModel.getTitle());

        //邮件的文本内容
        message.setContent(emailModel.getMessage(), "text/html;charset=UTF-8");

        //5、发送邮件
        ts.sendMessage(message, message.getAllRecipients());

        // re=ts
        ts.close();


    }
}

不会获取邮箱检验码的点击此处
emailModel

public class EmailModel {
    private String title;//邮件标题
    private String message;//邮件内容
    private String emailReciver;//邮件的收件人

    public EmailModel(String title, String message, String emailReciver) {
        this.title = title;
        this.message = message;
        this.emailReciver = emailReciver;
    }

    public String getTitle() {
        return title;
    }

    public void setTitle(String title) {
        this.title = title;
    }

    public String getMessage() {
        return message;
    }

    public void setMessage(String message) {
        this.message = message;
    }

    public String getEmailReciver() {
        return emailReciver;
    }

    public void setEmailReciver(String emailReciver) {
        this.emailReciver = emailReciver;
    }
}

如何使用呢，我们可以创建一个工具类MailUtils

public class MailUtils {
    private static final JavaSocket javaSocket = new JavaSocket();

    /**
     * 发送邮件
     * 发送成功：true
     * 发送失败：fasle
     *
     * @param title   邮件主题
     * @param message 邮件内容
     * @return
     */
    public static Boolean senEmail(String title, String message, String emailReceiver) {
        Boolean re = false;
        try {
            javaSocket.sendEmail(new EmailModel(title, message, emailReceiver));
            re = true;
        } catch (Exception e) {
            re = false;
            e.printStackTrace();
        }
        return re;

    }

    public static void main(String[] args) {
        Boolean re = senEmail("测试数据", "测试内容", "649623649");
        System.out.println(re);
    }
}

上面只是实现了发送纯文本类型的邮件，更多类型的邮件服务可以参考以下方式：
