java spring 郵件發送

一個簡單的關於spring的發送郵件案例：

環境：idea ，spring

•       首先加入關於email的jar

pom.xml中添加

<dependency>
  <groupId>javax.mail</groupId>
  <artifactId>mail</artifactId>
  <version>1.4</version>
</dependency>

• 建立用戶entity

package com.slh.email;

import javax.mail.Authenticator;
import javax.mail.PasswordAuthentication;

/**
 * Created by Tyson on 2018/8/10.
 */
public class MyAuthenticator extends Authenticator {

    private String username;
    private String password;

    public MyAuthenticator() {
    }

    public MyAuthenticator(String username, String password) {
        this.username = username;
        this.password = password;
    }

    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    @Override
    protected PasswordAuthentication getPasswordAuthentication() {
        return new PasswordAuthentication(username, password);
    }

}

• 創建發送郵件業務類(163郵箱爲例)

package com.slh.email;

import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import java.util.Date;
import java.util.Properties;

/**
 * Created by Tyson on 2018/8/10.
 */
public class SendMail {

    public void sendMail01() throws MessagingException {
        /***
         * 1. 設置郵件服務器信息
         * 2. 進行用戶名面認證
         * 3. 創建消息
         * 4. 設置收件人和發件人
         * 5. 發送郵件
         * */

        // 定義郵箱服務器配置
        Properties props=new Properties();
        // 163 郵件服務器地址
        props.put("mail.smtp.host", "smtp.163.com");
        // 163 郵件服務器端口
        props.put("mail.smtp.port", "25");
        // 163 郵件服務器認證屬性
        props.put("mail.smtp.auth", "true");// 一定要加引號


        Session session = Session.getInstance(props,
                new MyAuthenticator("郵箱地址(如：[email protected])","授權碼(郵箱設置中開啓授權碼)"));

        Message message = new MimeMessage(session);

        //發件人
        message.setFrom(new InternetAddress("[email protected]"));
        //收件人
        message.setRecipient(Message.RecipientType.TO,new InternetAddress("[email protected]"));

        message.setSentDate(new Date());//發送時間
        message.setSubject("SGCSGCSGC");
        message.setText("SGCSGCSGCSGCSGCSGCSGCSGCSGCSGCSGCSGCSGCSGCSGCSGCSGCSGCSGCSGCSGC");

        // 發送
        Transport.send(message);
    }
}

•  編輯測試

package com.slh.email;

import org.junit.Test;

import static org.junit.Assert.*;

/**
 * Created by Tyson on 2018/8/10.
 */
public class SendMailTest {
    @Test
    public void sendMail01() throws Exception {

        SendMail sendMail = new SendMail();
        for(int i=0;i<=22;i++){
            sendMail.sendMail01();
        }
        System.out.println("發送完畢");

    }

}
