java 發送 mail 純文本發送和html格式發送
一:需要引入mail maven jar包
<!--郵件發送包-->
<dependency>
<groupId>javax.mail</groupId>
<artifactId>mail</artifactId>
<version>1.4.7</version>
</dependency>
二:代碼示例
- 2.1 定義消息實體類
package textAnalysis.dto;
/**

*/
public class MailInfo {
//郵箱服務器 如smtp.163.com
private String host ;
//用戶郵箱 如**@163
private String formName ;
//用戶授權碼 不是用戶名密碼 可以自行查看相關郵件服務器怎麼查看
private String formPassword ;
//消息回覆郵箱
private String replayAddress ;
//發送地址
private String toAddress ;
//發送主題
private String subject ;
//發送內容
private String content ;
public String getHost() {
return host;
}
public void setHost(String host) {
this.host = host;
}
public String getFormName() {
return formName;
}
public void setFormName(String formName) {
this.formName = formName;
}
public String getFormPassword() {
return formPassword;
}
public void setFormPassword(String formPassword) {
this.formPassword = formPassword;
}
public String getReplayAddress() {
return replayAddress;
}
public void setReplayAddress(String replayAddress) {
this.replayAddress = replayAddress;
}
public String getToAddress() {
return toAddress;
}
public void setToAddress(String toAddress) {
this.toAddress = toAddress;
}
public String getSubject() {
return subject;
}
public void setSubject(String subject) {
this.subject = subject;
}
public String getContent() {
return content;
}
public void setContent(String content) {
this.content = content;
}
}
- 2.2 兩種方式實現
首先你需要獲取你的授權碼,以@163.com爲例 http://blog.csdn.net/hughnes/article/details/52070878
sendTextMail是純文本發送
sendHtmlMail是HTML格式標籤發送 這種方式可以識別html標籤
package textAnalysis.util;
import textAnalysis.dto.MailInfo;
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.Date;
import java.util.Properties;
/**

*/
public class MailSendUtil {
private final static String host = "smtp.163.com"; //163的服務器
private final static String formName = "[email protected]";//你的郵箱
private final static String password = "***********"; //授權碼
private final static String replayAddress = "[email protected]"; //你的郵箱
public static void sendHtmlMail(MailInfo info)throws Exception{
info.setHost(host);
info.setFormName(formName);
info.setFormPassword(password); //網易郵箱的授權碼~不一定是密碼
info.setReplayAddress(replayAddress);
Message message = getMessage(info);
// MiniMultipart類是一個容器類,包含MimeBodyPart類型的對象
Multipart mainPart = new MimeMultipart();
// 創建一個包含HTML內容的MimeBodyPart
BodyPart html = new MimeBodyPart();
// 設置HTML內容
html.setContent(info.getContent(), "text/html; charset=utf-8");
mainPart.addBodyPart(html);
// 將MiniMultipart對象設置爲郵件內容
message.setContent(mainPart);
Transport.send(message);
}
public static void sendTextMail(MailInfo info) throws Exception {
info.setHost(host);
info.setFormName(formName);
info.setFormPassword(password); //網易郵箱的授權碼~不一定是密碼
info.setReplayAddress(replayAddress);
Message message = getMessage(info);
//消息發送的內容
message.setText(info.getContent());
Transport.send(message);
}
private static Message getMessage(MailInfo info) throws Exception{
final Properties p = System.getProperties() ;
p.setProperty("mail.smtp.host", info.getHost());
p.setProperty("mail.smtp.auth", "true");
p.setProperty("mail.smtp.user", info.getFormName());
p.setProperty("mail.smtp.pass", info.getFormPassword());
// 根據郵件會話屬性和密碼驗證器構造一個發送郵件的session
Session session = Session.getInstance(p, new Authenticator(){
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(p.getProperty("mail.smtp.user"),p.getProperty("mail.smtp.pass"));
}
});
session.setDebug(true);
Message message = new MimeMessage(session);
//消息發送的主題
message.setSubject(info.getSubject());
//接受消息的人
message.setReplyTo(InternetAddress.parse(info.getReplayAddress()));
//消息的發送者
message.setFrom(new InternetAddress(p.getProperty("mail.smtp.user"),"餘高峯"));
// 創建郵件的接收者地址,並設置到郵件消息中
message.setRecipient(Message.RecipientType.TO,new InternetAddress(info.getToAddress()));
// 消息發送的時間
message.setSentDate(new Date());
return message ;
}
}
測試
@Test
public void send(){
String mail = "[email protected]"; //發送對象的郵箱
String title = "我有一句話跟你說";
String content = "<div>你不在學校嗎?</div><br/><hr/><div>記得28號來學校</div>";
MailInfo info = new MailInfo();
info.setToAddress(mail);
info.setSubject(title);
info.setContent(content);
try {
//MailSendUtil.sendTextMail(info);
MailSendUtil.sendHtmlMail(info);
} catch (Exception e) {
System.out.print("'"+title+"'的郵件發送失敗!");
e.printStackTrace();
}
}
採用的Junit的方式測試的採用 sendTextMail 的結果是
