Java實現簡單郵件發送功能
本文實例為大傢分享瞭Java實現簡單郵件發送的具體代碼，供大傢參考，具體內容如下
需要的jar包:
- activation-1.1.1.jar
- mail-1.4.7.jar
QQ郵箱設置開啟POP3/SMTP服務,並獲得授權碼
java實現簡單郵件發送
import com.sun.mail.util.MailSSLSocketFactory;
import javax.mail.*;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import java.util.Properties;
public class Mail1 {
public static void main(String[] args) throws Exception {
//要發送郵件,需要獲得協議和支持!開啟服務POP3/SMTP服務 授權碼: fsxqgovorymigfeb
Properties prop=new Properties();
prop.setProperty("mail.host","smtp.qq.com");//設置QQ郵件服務器
prop.setProperty("mail.transport.protocol","smtp");//設置郵箱發送協議
prop.setProperty("mail.smtp.auth","true");//需要驗證用戶名密碼
//QQ郵箱還有設置SSL加密
MailSSLSocketFactory sf=new MailSSLSocketFactory();
sf.setTrustAllHosts(true);
prop.put("mail.smtp.ssl.enable","true");
prop.put("mail.smtp.ssl.socketFactory",sf);
//1.創建定義整個應用程序所需要的環境信息的Session對象
Session session=Session.getDefaultInstance(prop, new Authenticator() {
@Override
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication("[email protected]","fsxqgovorymigfeb");
}
});
//開啟session的debug模式,這樣就可以查看運行狀態瞭
session.setDebug(true);
//2.通過session對象獲得transport對象
Transport transport = session.getTransport();
//3.使用郵箱的用戶名和授權碼連上郵件服務器
transport.connect("smtp.qq.com","[email protected]","fsxqgovorymigfeb");
//4.創建郵件:寫郵件
MimeMessage message = new MimeMessage(session);
message.setFrom(new InternetAddress("[email protected]"));//發件人
message.setRecipient(Message.RecipientType.TO,new InternetAddress("[email protected]"));//收件人
message.setSubject("你好");//郵件主題
message.setContent("<h1 style='color: red'>你好</h1>","text/html;charset=utf-8");//郵件內容
//5.發送郵件
transport.sendMessage(message,message.getAllRecipients());
//6.關閉連接
transport.close();
}
}
java實現復雜郵件發送( 帶文件 )
import com.sun.mail.util.MailSSLSocketFactory;
import javax.activation.DataHandler;
import javax.activation.FileDataSource;
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.util.Properties;
public class Mail1 {
public static void main(String[] args) throws Exception {
//要發送郵件,需要獲得協議和支持!開啟服務POP3/SMTP服務 授權碼: fsxqgovorymigfeb
Properties prop=new Properties();
prop.setProperty("mail.host","smtp.qq.com");//設置QQ郵件服務器
prop.setProperty("mail.transport.protocol","smtp");//設置郵箱發送協議
prop.setProperty("mail.smtp.auth","true");//需要驗證用戶名密碼
//QQ郵箱還有設置SSL加密
MailSSLSocketFactory sf=new MailSSLSocketFactory();
sf.setTrustAllHosts(true);
prop.put("mail.smtp.ssl.enable","true");
prop.put("mail.smtp.ssl.socketFactory",sf);
//1.創建定義整個應用程序所需要的環境信息的Session對象
Session session=Session.getDefaultInstance(prop, new Authenticator() {
@Override
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication("[email protected]","fsxqgovorymigfeb");
}
});
//開啟session的debug模式,這樣就可以查看運行狀態瞭
session.setDebug(true);
//2.通過session對象獲得transport對象
Transport transport = session.getTransport();
//3.使用郵箱的用戶名和授權碼連上郵件服務器
transport.connect("smtp.qq.com","[email protected]","fsxqgovorymigfeb");
//4.創建郵件:寫郵件
MimeMessage message = new MimeMessage(session);
message.setFrom(new InternetAddress("[email protected]"));//發件人
message.setRecipient(Message.RecipientType.TO,new InternetAddress("[email protected]"));//收件人
message.setSubject("你好");//郵件主題
//message.setContent("<h1 style='color: red'>你好</h1>","text/html;charset=utf-8");//郵件內容
//=============================================================================
//帶圖片的內容
MimeBodyPart image = new MimeBodyPart();
DataHandler dh = new DataHandler(new FileDataSource("E:\\IDEA\\JavaWeb\\mail-java\\src\\tx.png"));//圖片需要經過數據處理... DataHandler:數據處理
image.setDataHandler(dh);//在Body中放入處理的圖片數據
image.setContentID("tx.png");//給圖片設置ID
//準備正文數據
MimeBodyPart text = new MimeBodyPart();
text.setContent("這是一封郵件正文帶圖片<img src='cid:tx.png'>的郵件","text/html;charset=utf-8");
//描述數據關系
MimeMultipart mm = new MimeMultipart();
mm.addBodyPart(text);
mm.addBodyPart(image);
mm.setSubType("mixed");
//設置到消息中,保存修改
message.setContent(mm);
message.saveChanges();
//=========================================================================
//5.發送郵件
transport.sendMessage(message,message.getAllRecipients());
//6.關閉連接
transport.close();
}
}
Spring實現
1、添加依賴
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-mail</artifactId> </dependency>
2、編寫配置文件
[email protected] spring.mail.password=fsxqgovorymigfeb spring.mail.host=smtp.qq.com spring.mail.properties.mail.smtp.ssl.enable=true
3、編寫測試類
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSenderImpl;
import org.springframework.mail.javamail.MimeMessageHelper;
import javax.mail.MessagingException;
import javax.mail.internet.MimeMessage;
import java.io.File;
@SpringBootTest
class DemoApplicationTests {//簡單郵件
@Autowired
JavaMailSenderImpl mailSender;
@Test
void contextLoads() {
//發送郵件
//收件人
//內容
SimpleMailMessage message = new SimpleMailMessage();
message.setSubject("測試");
message.setText("Hello");
message.setFrom("[email protected]");
message.setTo("[email protected]");
mailSender.send(message);
}
@Test
public void test2() throws Exception {//復雜郵件
MimeMessage mimeMessage = mailSender.createMimeMessage();
MimeMessageHelper helper = new MimeMessageHelper(mimeMessage, true);
helper.setSubject("測試");
helper.setText("Hello",true);
//附件
helper.addAttachment("1.jpg",new File(""));
helper.setFrom("[email protected]");
helper.setTo("[email protected]");
mailSender.send(mimeMessage);
}
}
